I have a ListView, displaying some items, containing an ImageView filled with a standard image at first and a line of text.
What I wanna do is downloading one thumb after another with an AsyncTask and step for step change the standard image with the downloaded one. How to realise this?
The ListView contents are managed by an enhanced ArrayAdapter.

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.
However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).
1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.
2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?
3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

View 2 Replies View RelatedI have a list (ListView) which displays news items. They contain a image, title and some text. The image is loaded in a separate thread (with a queue and all) and when the image is downloaded, I now call notifyDataSetChanged() on the list adapter to update the image. This works, but getView() is getting called way to often now, since notifyDataSetChanged() calls getView() for all visible items. I want to update just the single item in the list. How would I do this?Problems I have with my current approch is that the list is slow and I have a fadein animation on the image which happens every time a single new image in the list is loaded.

View 1 Replies View RelatedI have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded.
View 1 Replies View RelatedIn Android, I want to present the user with a list. When an item on the list is selected some action is performed, and this list item is no longer selectable. It is also 'grayed out' or the like to indicate that it cannot be selected the next time the list is displayed. I have seen the isSelectable() override in Adapter, but I believe this causes the item to be treated as a separator, which causes visual problems. And I have not found a way to 'gray out' an item.
View 4 Replies View RelatedI have a list view and an adapter that sets alternating background colors to the list items ("zebra" list style):
public View getView(final int position, View convertView, ViewGroup parent) {
int colorPos = position % colors.length;
...
convertView.setBackgroundColor(colors[colorPos]);
return convertView;}
But now, when i select an item using scroll wheel, or when I click an item, the original colors for selecting/clicking do not override my custom backgrounds (I can see the original color below the one I set).
How can I set the original colors for these states?
I cannot find any example of a widget showing a scrollable list of items (e.g. text) since the widget api says there is no listview, no scrollview etc.. at all, how to implement a scrollable list inside a widget?
For example a list like friends-stream from HTC shows or many other widgets around.... do i have to code my own list-implementation for a widget.
The way I want it is, per row there will be a text and is followed by a right arrow button, so that the user can click on that button to edit the content of that row. If the user is using the keypad, by using the left and right buttons on the keypad, he should be able to select the textview or the Button in that particular row. I have seen this in a couple of apps. The way I see that working on those apps appear as if they are maintaining two lists in parallel.
The reason i felt it this way is, if I am on row 1 of the list and if I press the right key on the phone keypad, then the right arrow button will get highlighted and now if I use the down key or if I keep pressing the down key, then the focus will scroll through that arrow button only as if that is an another parallel list constructed. I don't know if that is a good way to do it. I tried many for getting this to work, but couldn't succeed.
I have a listview from an SQLDatabase using custom CursorAdaptor. I would like to go back to the activity that I used to create the items when I click on them in the listview. So that I can edit the entries. But nothing happen when I implement the OnItemClick method and the getItemId() on the CursorAdapter even though am not sure I am correct there. Here is my Code:
public void onItemClick(AdapterView<?> adapview, View view, int position, long rowId) {
Cursor c = adapter.retrieveRow(rowId); // retrieve row from Database
Intent edit = new Intent(this,NewItem.class);
edit.putExtra(DBAdapter.KEY_ID, rowId);
edit.putExtra(DBAdapter.Title, c.getString(c.getColumnIndex(DBAdapter.Title)));
edit.putExtra(DBAdapter.DATE, c.getString(c.getColumnIndex(DBAdapter.DATE)));
startActivity(edit); } public long getItemId(int id){ return id; }
I've got the following main.xml:
<?xml version="1.0" encoding="utf-8"?> <AbsoluteLayout
android:id="@+id/widget0" android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" >
<ListView android:id="@+id/listview" android:layout_width="315px"
android:layout_height="379px" android:layout_x="2px" android:layout_y="50px" >
</ListView> <TextView android:id="@+id/title" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Select device:" android:textSize="17sp"
android:layout_x="-2px" android:layout_y="1px" >
</TextView> <Button android:id="@+id/refresh" android:layout_width="109px"
android:layout_height="wrap_content" android:text="Refresh" android:layout_x="209px android:layout_y="7px" >
</Button> </AbsoluteLayout>
The main class does nothing but drawing the layout. I've got the following class and layout for the listitems:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"

import android.view.View; import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter;
import android.widget.ListView; import android.widget.TextView;
import android.widget.Toast;
public class BTListView extends ListActivity {
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, COUNTRIES)); ListView lv = getListView();
lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show(); } } ); }
Countries is just an array with a list of countries, some dummy values. Now, how do I make the list items of the BTListView class go in the ListView (with @+id/listview) of the main class? Now my list works, but it isn't clickable anymore. This is the code:
ListView lv = getListView(); lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), "lolwat", Toast.LENGTH_SHORT).show();
} } );
Can any one please tell me how to add multiple items (images/text) in list view?

I am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item.I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array?What is the best way to do this?
View 2 Replies View RelatedWhen your intent kicks knocked on the head by the OS and then restored / recreated (for example when you slide out the keyboard on the G1) if you have a ListView populated with items in an activity they appear after the recreate. However, if you have a dialog box full of list items and do the same steps, the ListView comes back up empty when the window is redrawn after the slide.
Is this an Android bug? My list is a pain in the neck to pack into a bundle, it consists of Address objects, and there might be ten of them. Am I doing something "un-android?"
