May 27, 2009

I want to create a listview with rows that have an image and two textviews. This must be a very common activity but I can't find a class/or source code that does this.

Android :: Styling Added Rows To ArrayAdapter ListView Android

Jul 15, 2010

I have a ListView that I want to use with an ArrayAdapter to add different styled rows. The rows are created on different states in my application, and depending on the different states the rows should be styled(like colors and stuff). Here is some pseudo-code:

on creation:
mArrayAdapter = new ArrayAdapter(this, R.layout.message);
mView = (ListView) findViewById(R.id.in);
mView.setAdapter(mArrayAdapter);

On different states, which is triggered by another thread using a MessageHandler, add a row to the list containing a message: mArrayAdapter.add("Message");

This works fine, messages are popping up in the list depending on different states, but I want to have the rows styled differently. How to do this? Is the solution to create a custom ArrayAdapter with a custom Add() method?

Android :: Double Rows In Listview With ArrayAdapter - Android

Oct 13, 2010

I'm new to android programming and I would like some help. I have the following code:

Object[] list_cities = parsedData.getCityname().toArray();
Object[] list_countries = parsedData.getCountryname().toArray();

// Display the available locations
list_search.setAdapter(new ArrayAdapter<Object>(this, android.R.layout.simple_list_item_2, android.R.id.text1, list_cities));
list_search.setAdapter(new ArrayAdapter<Object>(this, android.R.layout.simple_list_item_2, android.R.id.text2, list_countries));

I would like to display double rows for each entry in the list (city and country) but I have no luck. With the above code I only see the countries but not the cities. Is there any way to add both the adapters to the list_search so I can see all the data?

Android :: Multiple Views For For Row In ListView

Jan 17, 2010

I have a ListView that could have 4 different views for a row depending on the data for the row. I have the ListView working correctly overriding getViewTypeCount and getItemViewTYpe. I originally was trying to dynamiclly update the view type count as new views were inflated by forcing calls to getViewTypeCount because it was possible that maybe one or two views may be all that would be needed. The app never functioned correctly crashing after there was more than one view added. The problem was fixed by setting getViewTypeCount to always return 4. I noticed getViewTypeCount is automatically called on app start-up and never called again unless a force call is made. So I'm just curious if this can be changed dynamically or do you need to know the number of max views you can possibly have and override getViewTypeCount to return that max value.

Android :: Removing Items From ListView/ArrayAdapter Doesn't Work After Text Filtering

Jul 10, 2010

I have an Android ListView, backed by an ArrayAdapter. When the user clicks on an item in the list, that item is removed. This all appears to work fine, you can click on each item until there are no items left.

However, it all goes wrong once text filtering occurs. Once the list has been filtered once, even if that filter is cleared, all subsequent calls to remove(Object) on the adapter fail to remove the item from the visible list. I've tried calling ListView.clearTextFilter() before removing the item, calling it after removing the item, and not calling it all. There's no difference.

I've looked through the source for ArrayAdapter.java and it seems that once filtering is set, the adapter uses one collection to respond to queries but updates a different one. I can see no obvious way to get it to revert its behaviour. Is this a bug or am I missing something?

Android :: Accessing Rows In ListView - Change Text / Styling

Sep 27, 2010

I'm having trouble changing the data held within a TextView inside of a listView. I can access the data and send a toast of the text, but the list isn't updated when I change it.

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, presidents));
ListView lv = getListView();
lv.setTextFilterEnabled(true);
ListAdapter list_adapter = lv.getAdapter();
TextView var_x = (TextView) list_adapter.getView(0,null,null);
ListView list = getListView();
int count = list.getChildCount();
Toast.makeText(getApplicationContext(),(var_x).getText(),Toast.LENGTH_SHORT).show();
var_x.setText("not a president");}

How can I change the text/styling of a row once I've already created it?

Android :: Adding Iconified Rows To Existing ArrayAdapter

Mar 26, 2010

I am developing an application which requires me to load first twenty rows (consisting on icons and two text fields) and if I have more rows I need to display a button. When i click this button I want to display more twenty rows( again iconified).My current approach which is working is that on the button click I create one more activity which will have the previous rows and the new rows. In this case the cursor is set to the very first row.But I want to have something like Facebooks "Older Post" where the new rows get appended to the old ones and the cursor is set to the last row to which the new rows are added.Please can anyone give me ideas on how to achieve this. That is, how to add rows (iconified) to the existing array adapter.

Android : Avoid Re-drawing All Views In An ArrayAdapter?

Mar 25, 2010

I have an ArrayAdapter powering a ListView. I would like to change the data behind the ArrayAdapter and update the ListView's. Sounds like notifyDataSetChanged(); would be exactly what I am looking for, but it updates the entire ListView, and I would prefer to update on a row-by-row basis.

Is there a way to do this with ArrayAdapter, or do I need to manage my data some other way if I want this functionality?

Android :: Pros - Cons Of Multiple Activities In An App Vs One Activity - Multiple Views

Aug 16, 2010

Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.

I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.

What advantages of multiple activities am I missing?

Android :: ListView ArrayAdapter Data Updates Best Practices

Aug 26, 2010

I have an activity with multiple list views that are continuously receiving new values form a socket thread, another thread parses the data and updates the array adapters, then the ui thread calls notifyDataSetChanged() to cause the list to refresh.

My issue is that im refreshing all the list a couple of time a second, this causes the UI to be very laggy when some animations need to happen.

I was wondering what the best way is to update multiple lists with multiple value changes every second?

Android :: Removing Items From A ListView/ArrayAdapter Activity

Aug 24, 2009

I have a list (of messages) and I want to give the user the ability to remove these items from the list. I have extended an ArrayAdapter and give it an ArrayList of my messages and would like to simply remove an item from that list and then refresh the listview instead of reloading the entire list of sent messages. The problem is, if there's only one message and I remove it using listAdapter.remove(messageObject), the adapter is still calling getView and then throwing NullPointerExceptions all over the place. I'm not sure what the best way is to go about this.

Android :: Wrong Image Show Up In ListView Rows

Oct 8, 2010

I use this code in my getView:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {

LayoutInflater vi = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listrow, null);
}
Order o = items.get(position);

if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
ImageView thumb = (ImageView) v.findViewById(R.id.icon);

if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());
}

}
return v;}

The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.

Android :: Losing Ability To Click On Rows In The ListView

Aug 30, 2010

So, basically I have a custom View that contains a ListView with a custom Adapter that has the ability to read in information from the network (dumbed down HTML) and display it on a row by row basis. All of this works, but I need the text that is read in to be parsed as HTML which contains links that can be tapped on and launched in browser. I managed to do this by:

text.setText(Html.fromHtml(textBuffer), TextView.BufferType.SPANNABLE);
text.setMovementMethod(LinkMovementMethod.getInstance());

Works great, any <a href=""></a> links in the text are displayed as links and can be tapped. This is a side effect of now making it so the rest of the rows in the ListView cannot be tapped (or tapped and held). Basically, all the rows are non-selectable now. Is there any way to achieve both of what I need?

Android :: Strange ListView Scrolling - Rows Turn Light Green

Aug 16, 2010

I have a ListView in my app that has a background image. All of the rows are a semi transparent white (#35FFFFFF). Whenever I scroll the list, the rows turn a light green that obscures the background image until I stop scrolling (usually--sort of unpredictable). Sometimes it flickers between the background image/color and the green. And yes, I have set the cache color hint to #00000000. Any advice about this would be appreciated.

ListView xml:

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"

Android :: Color Code Individual Rows In ListView As Done In MESSAGING Application?

Feb 28, 2010

How can I color code individual rows in a ListView exactly like it is done in the native MESSAGING app? I do NOT want to simply do alternating rows, but I want to copy the format used in the MESSAGING app, where message rows have a different background color based on the username of the message. FYI: I am currently extending SimpleAdapter and overriding getView(int position, View convertView, ViewGroup parent) . In this method I am trying to calculate setting the background color based on the position as compared to a list of 'positions to highlight' that I am maintaining each time I update the list, but so far this is only working the first time the list is updated. In class that overrides SimpleAdapter:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
if(highlightPositions.contains(new Integer(position))){
view.setBackgroundColor(highlightColor);
}
else{
view.setBackgroundColor(normalColor);
}
return view;}

Android :: How To Use Multiple Map Activities / Views?

Jul 31, 2010

My situation is the following: I have written one MapActivity class that is able to display a set of places as well as single places. On startup, the application creates an instance of this MapActivity and displays multiple places. If the user clicks on a certain place, then a new Activity is launched that shows the details of the selected place. This activity has a menu item that allows the user to view the place on a map - this causes that a new instance of the MapActivity is created, except that now only this single place is displayed.

The problem now is that if the user navigates back to the first MapActivity (the one that shows multiple places) the tiles won't be loaded anymore + sometimes OutOfMemoryErrors are encountered. According to the Android JavaDocs, it is only possible to have one MapActivity per process. However, I don't want to define my MapActivity as a singleInstance/singleTask, since the user should always be able to navigate back to the first MapActivity that shows multiple places. I have seen that the Google Places app (which has come with Google Map 4.4) for Android uses multiple MapActivity instances. How is this possible?

Android :: Android - Continue Scrolling In ListView With Clickable Items In Rows

Nov 19, 2010

I've been trawling the internet looking for an answer for several hours, but I can't seem to find anyone who has been able to solve this. I've got a listview which uses enter code herea custom adapter. A row looks like this. The list is filled by an array. Everything works great. Now, I want the ImageView and the ToggleButton to react to clicks, so I implement the OnClickListener in my adapter, put the items position in each view's tag, and then I set their onclicklistener to this. Works great, except now I can't use the onListItemClick for starting an activity for the item! OK, I say, I just make the relativelayout holding the text in the middle there use the same onclicklistener. Works great. Everything is clickable, and life is good.

EXCEPT! Now, when I scroll the list, I cannot "continue" the scroll by just flinging again. This causes the scrolling to stop, and I have to fling once more to get it going again. It seems the onclick-thingy causes the fling-motion to be interpreted as a tap or something (it does not trigger the logic within onClick).
I know that this is possible by just going to the phone list on my HTC Hero, which has exactly the kind of layout and behaviour I want from my app. This app even seems to have the onItemClickListener working. So how can I make sure the list keeps scrolling, and still be able to click the togglebutton, listitem and the imageview? I've been stuck on this all day, and it's giving me a headache
