Android :: Cannot Display Image Correctly Using Custom Item Layout In ListView

Apr 22, 2010

I am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.

This is the item layout I made (post_item.xml):

CODE:........................

I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.

I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).

When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).

I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.

Here is my code for the Adapter:

CODE:..............

And this is the code to prepare the items:

CODE:.........................

Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?

Android :: OnClick() Event On An Item Of ListView Custom Row Layout

Nov 15, 2010

I have a ListView whose rows are formatted by me. Each row has a mix of ImageView and TextView. I have also implemented my own adapter and am able to draw each row through it.

Now, I would want something like this-

User clicks on an ImageView (not anywhere else on the row, but only this ImageView should respond to clicks)
I get to know the position of the row whose ImageView was clicked.

I have tried many things for this and have wanted my code to be as efficient as possible (in terms of overkill).
Currently i can capture the click event on that particular ImageView only, but I can't know which row was clicked.

I have provided an attribute in the Row XML like this-

CODE:..................

And in my code, I have a method like this:

CODE:..............

I can get the parent row (perhaps) but am not sure how to go further from here.

Android :: Layout For ListView Item Like Twitter

Sep 11, 2010

As you already know, in Twiiter application, twitt content stays in the right hand side of the Username, and in second line, the twitt content stays back to the left of the parent layout. (which is similar to the Listview item's layout of Facebook Application)

My problem is the username and twitt content belong to 2 different columns. Could you please tell me the way to fix the problem?

Deleting Item From ListView Layout And SharedPreferences

Sep 14, 2013

How to delete an item from a ListView.

I have a layout which includes the listview, an edittext and a button. On button click, the edittext's string is added to the listview. Clicking on a listview item opens a dialog which asks for confirmation to delete that item. When confirmation is received, the item appears to delete. But when the delete button is clicked on another item, the item deletes, but the previous item reappears in its spot. From my limited understanding, I assume that the item doesn't delete from the SharedPreferences, and so when they are loaded again, the item reappears. I've tried clearing the SharedPreferences before saving after delete, but this didn't work (though I could've been doing it wrong).

I've included the whole class incase to test it out in IDE. I understand there are a lot of unneeded objects and the code is quite messy which is a result of me screwing around with the code to try and get this to work. Though everything works as it should, aside from deletion.

[HIGH]
package com.example.send2omni;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;

[Code]....

And here's the layout to save some time:

[HIGH]
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
androidrientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"

[Code]...

Android :: ListView Item From Custom Adapter Not Selectable

Jul 1, 2010

I'm making a custom adapter so that I can display a list of items with icons which looks like the menu that comes up when you long click the home screen. For some reason though the list items are not clickable. The can be navigated to with the D-pad but they cannot be clicked in any way. I thought maybe the problem was with the AlertDialog I was using so I replaced a working adapter I had elsewhere but I have the same issue there. My adapter looks like this:

ArrayList<IconListItem> mItems; LayoutInflater mInflater;
public IconListAdapter(Context context, ArrayList<IconListItem> items) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mItems = items;
} public IconListAdapter(Context context) {
this(context, new ArrayList<IconListItem>());
} public void add(IconListItem item) { mItems.add(item);
notifyDataSetChanged(); return item;
} public void remove(IconListItem item) { mItems.remove(item); notifyDataSetChanged();
} @Override public int getCount() { return mItems.size();
} @Override public IconListItem getItem(int position) { return mItems.get(position);
} @Override public long getItemId(int position) { return position;
} @Override public View getView(int position, View convertView, ViewGroup parent) { View view;
if(convertView == null){ view = mInflater.inflate(R.layout.two_line_icon_list_item, null);
} else { view = convertView; } IconListItem item = mItems.get(position);

TextView lineOne = (TextView) view.findViewById(R.id.firstLine);
TextView lineTwo = (TextView) view.findViewById(R.id.secondLine);
ImageView iconImage = (ImageView) view.findViewById(R.id.icon);
lineOne.setVisibility(View.VISIBLE); lineTwo.setVisibility(View.VISIBLE);
iconImage.setVisibility(View.VISIBLE); lineOne.setText(item.getText());
if (item.getSubtext() == null) lineTwo.setVisibility(View.GONE);
else lineTwo.setText(item.getSubtext());
if (item.getIcon() == null) iconImage.setVisibility(View.GONE);
else iconImage.setImageDrawable(item.getIcon());
return view; }

And the XML it's inflating:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="6dip" >
<ImageView android:id="@+id/icon" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_marginRight="6dip" />
<LinearLayout android:orientation="vertical" android:layout_width="wrap_content"
android:layout_weight="1" android:layout_height="fill_parent" >
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1"android:gravity="center_vertical"
android:id="@+id/firstLine" android:ellipsize="marquee" android:inputType="text" />
<TextView android:layout_width="wrap_content" android:layout_height="0dip"
android:layout_weight="1" android:ellipsize="marquee"
android:id="@+id/secondLine" android:inputType="text" />
</LinearLayout> </LinearLayout>

When I say they are not clickable, I mean that they items do not highlight in orange when I press them nor does onItemClick ever get called. In my code I have this, a different adapter for another purpose and it works perfectly

this.foos= foos; fa = new FooAdapter(this.foos); fooList.setAdapter(fa);
// View the details for an item when it is selected
fooList.setOnItemClickListener(new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MyActivity.this, MyOtherActivity.class);
i.putExtra("foo", ((fooAdapter)arg0.getAdapter()).getItem(arg2));
i.putExtra("list_position", arg2);
MyActivity.this.startActivityForResult(i, 0);
} } );

But when I swap out the first 3 lines for
IconListAdapter ila = new IconListAdapter(this);
ila.add(0, "Test 1", android.R.drawable.ic_menu_mylocation);
ila.add(0, "Test 2", android.R.drawable.ic_menu_edit);
ila.add(0, "Test 3", android.R.drawable.ic_menu_search);
groupList.setAdapter(ila);
I t stops working.

Android :: Custom ListView Selected Item Children?

Oct 27, 2010

I have a custom listview row that contains a number of textView components. Instead of the "standard" single text item, I have created a item where each listview row contains several bits of information. For this example, I have a record id, a name, and a description for each row in the listview. I have my listview populated via
this.mDbHelper = new RecordDBAdapter(this); this.mDbHelper.open();
Cursor c = this.mDbHelper.fetchAllRecords(); startManagingCursor(c);
String[] from = new String[] {RecordDBAdapter.ROW_ID, RecordDBAdapter.NAME,
RecordDBAdapter.DESCRIPTION};
int[] to = new int[] {R.id.recordId, R.id.lblName, R.id.lblDescription};
// Now create an array adapter and set it to display using our row
SimpleCursorAdapter records = new SimpleCursorAdapter(this, R.layout.record_row, c, from, to); this.list.setAdapter(dives);

Now what I want is to be able to access the recordId value within each clicked item. I've tried to follow the Android tutorials to no avail. They do something like
Object o = adapter.getItemAtPosition(position);
but that still doesn't help either. What I really want is to get the value of the recordId within each selected listItem. Does anyone know how this would be accomplished? Here is my onItemClick event:
protected OnItemClickListener onListItemClick = new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> adapter, View view, int position, long rowId) {
// My goal is either to grab the value of the
// recordId value from the textView, or from the adapter.
//Object o = adapter.getItemAtPosition(position);
//Tried this, no joy
Intent intent = new Intent(NeatActivity.this, SomeOtherActivity.class);
// intent.putExtra("selectedRecordId",val); //val here is a numerical record row id being passed to another activity.
startActivity(intent); } };

Android :: ListView Item Background Via Custom Selector

Apr 1, 2010

Is it possible to apply a custom background to each Listview item via the list selector?

The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible.

I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place.

For reference, this is the selector I'm using to try and get this working:

CODE:...............

And this is how I'm setting the selector:

Android :: Custom Separator In ListView Depening On Content Of Item

Oct 22, 2009

I've a ListView with items containing information about places with a rating and the distance to the current location.

The items are sorted into groups:

Group 1: within 500m
Group 2: 500m - 1km
Group 3: 1km - 1.5km

Withing these groups the items are sorted by their rating.Now I put out these items via my custom adapter (extension of BaseAdapter) into the ListView, which works perfectly.

However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any idea on how to realize this?

Android :: Display Images On Demand Inside A Listview / Find Out List Item Is On Screen?

Oct 31, 2010

I am building a android aplication which will be consuming a json file from the internet. This json file contains a list of news from a particular website. Each json object contains information such like title, summary, descripition and web links for the news thumbnail and the original image.

I will be displaying in a listview three information: the news thumbnail, the title and the summary. Here resides my problem. I dont want to load all thumbnails from the internet if they wont be displayed. What I am trying to say is that why download a thumbnail from the 30th news if the user wont scroll down the image. So, i will, initially only download the thumnails from those news that are being displayed in the screen and when the user scrolls down to see more news, as soon as the list item appers to the screen i want to download the image and then display.

Is there a way to achieve this? Is it possible to find out if the list item is on the screen? I have been searching all over the internet for a solution for this but i am running out of ideas.

Android :: Listview Custom Row Layout - Tried Many Combinations

Jun 13, 2010

I am having trouble getting my layout to give me result I need, I already tried many options and it seems that I'm doing something wrong or completely missing something.

I have a listview with a custom row layout I can't seem to working although it shouldn't be complex. I need of the list row to insist of:

Icon -- title text (bigger and bold) with a short multi line text under the title -- ImageButton

My problem in most of my tests is the icon to the right usually doesn't appear, I guess my center group grows and takes all the space of the button. My last failed attempt was with a Relative Layout, didn't have too much luck with a Linear Layout either.

Here is the row XML:

Android :: Custom Typface In Listview Row Layout

Aug 6, 2010

I am running a sqlite query and binding the returned data to a ListAdapter.

I have used the following example

ListActivity | Android Developers

However, having defined a seperate layout for the rows I cannot change the typeface for textview text1 to a custom one from assets

Here is the row layout

CODE:................

Here is the code from the andriod tutorial

CODE:............

We'll define a custom screen layout here (the one shown above), but typically, you could just use the standard ListActivity layout. setContentView(R.layout.custom_list_activity_view) ;

Query for all people contacts using the Contacts.People convenience class. Put a managed wrapper around the retrieved cursor so we don't have to worry about requerying or closing it as the activity changes state.

CODE:................

Now create a new list adapter bound to the cursor. SimpleListAdapter is designed for binding to a Cursor.
CODE:................

Specify the row template to use (here, two columns bound to the two retrieved cursor rows). mCursor, // Pass in the cursor to bind tonew String[]{People.NAME, People.COMPANY}, // Array of cursor columns to bind to. new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.

Android :: ListView With RadioButton In SingleChoice Mode And A Custom Row Layout

Nov 22, 2010

I have a ListView, which is in singleChoice mode. All I want is to display a RadioButton to the side, that when clicked highlights to say it is selected, and when a different one is clicked that one goes back to unselected and the new one becomes selected. Why is this so hard? This should not be this complicated. I've spent DAYS looking for an appropriate answer to this and I have found nothing, so I'm asking hopefully in a clear and concise manner.

My layout for the listview (R.layout.view_orders):

CODE:.............

My custom row (R.layout.orders_row):

CODE:.................

My onCreate() method:

CODE:.................

Now everything underlying works as expected, you click on a radiobutton and through it's tag I can appropriately select that item from the list and manipulate it how I want. However, when the first radio button is clicked, the last one will be selected. Click that same radio button again, and it is now selected as well. Click it once more and nothing happens, both the last and the first are selected. Now I click any other one on the list, it gets selected like expected. Click anyone of the selected radio buttons and nothing happens, the radio button remains selected.

I have tried using the following in onCreate():

CODE:.................

And that just shows no radio buttons at all. AWESOME.

Now maybe (read: most likely), I'm just dense and can't figure this out, but I've seen this question asked a lot with no real answer. Lots of references to other tutorials or to the Commonsware guy's book. However, the comments are old now and his repository has changed so much, that those are no longer correct answers.

So, does anyone have any idea how to get the expected functionality out of this? Or failing that, just pass me along the GMail app's source code.

Android :: Creating A Custom Image Based Layout?

Sep 26, 2010

Is it possible to create a layout based on (background) images? For example, there is well know app called Appie that uses this picture as a homescreen:

I might be able to recreate the layout with a TableLayout, but this will be difficult to get it perfectly aligned with the buttons in the image. The default layout options make it very difficult, or maybe impossible, to allow for selection of the buttons on the image (especially when the buttons are in an arc-path). Can anyone tell me how this is done?

Android :: Custom BaseAdapter - Dynamic Updates - Crash In ListView Layout

Feb 16, 2010

I'm trying to get my first Android app stable enough for the marketplace, and I've hit a brick wall with one exception that I don't understand. Probably I'm doing something stupid, but I can't tell what, and after several hours googling and experimenting, I thought I'd see if I can get some help. My Activity extends ListActivity, and the parts I think are most important are extracted below:

GroupedListAdapter is a simple class that extends BasedAdapter to provide headings for sections of the list (not unlike the Fancy ListView tutorials that are floating around).

I create this in onCreate, and it works fine. Inside onListItemClick, I do some actions which will create a different set of list contents. I "clear" the adapter, which empties the contents, and call reload, which repopulates it. Then I call notifyDataSetChanged.

Most often, this seems to work, but also fairly often, I get the exception following the code snippets below - this seems to indicate the ListView is not in sync with my changes. Lately this crash happens 100% of the time under the simulator.

Android :: Dumped XML Layout File Padding Positions Not Behaving Correctly

Dec 30, 2009

I've been trying to figure out how to make some sense of a dumped XML layout, and it's progressing 'pretty good'. The only thing I'm currently unsure about is the following:

I get the following result:

That's all good, but what I'm trying to figure out is how to convert the following code into the XML layout file:

Converting those values to decimal would result in:

CODE:.................

All good, but I've been trying to figure out what the (type 0x5 means). With all other types, the result is defined in the Android.util.TypedValue.class file

Decompiling that, gives the following result for 0x5:

Makes sense, in a way. But, I need to know what kind of value it is, so looking down, I find the following value:
