Android :: Change Properties Of Expandable List?
Jul 29, 2009I'm using BaseExpandableListAdapter, and there is a drop-down button (looks like an arrow) on the left side for each parent item to indicate that you can expand that item to view child items. The question is: How can I change the properties of that drop-down button such as its position? I basically want to move it a bit lower in each parent item.

Jun 8, 2010I 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?

Android :: Scroll ListView With Custom Adapter - Too Fast
Aug 4, 2010I have a listview with a custom arrayadapter that handles about 15 strings. The style of each row alternates (between labels and values for those labels--for example row 1 could be "email address" and row 2 would be the actual email address). I'm changing the style of each row to alternate like this in the arrayadapter's getView() method. So if the item at the current position is a label, I'll change the styling from the default row style (which is what the values have applied to them). When the listview first loads, the styling is perfect and just how I want it to be. If I scroll the list slowly up or down, it stays that way. However, if I scroll the list fast up and down, the styling of the value rows starts changing to that of the label ones until all of the rows have the styling of a label row. I've used custom adapters on other listviews in the app with no problems like this. Found out that it also changes all of the rows to the label styling on portrait->landscape orientation changes. Doesn't do this on landscape->portrait changes. Below is the adapter I'm using.
public class DetailsAdapter extends ArrayAdapter<String> { private TextView text = null; private String item = null;
public DetailsAdapter(Context context, int resource, int textViewResourceId, String[] objects) { super(context, resource, textViewResourceId, objects);
} @Override public View getView(int position, View convertView, ViewGroup parent) { text = (TextView) super.getView(position, convertView, parent); item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { text.setBackgroundColor(0xFF575757); text.setTextSize(15);
text.setTypeface(null, Typeface.BOLD); text.setPadding(8, 5, 0, 5);
} else { text.setPadding(15, 15, 0, 15); } return text;
} @Override public boolean isEnabled(int position) { item = getItem(position);
if (item.equals("Name") || item.equals("Mobile") || item.equals("Home") || item.equals("Email") || item.equals("Address")) { return false;
} else { return true; } } }
Android :: Populating Child List In Expandable Lists Using Dynamic Multidimensional Arrays
Jul 26, 2010I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.

Android :: Load ListPreference Items From Adapter?
May 29, 2010I'm setting out to create a settings activity for my app. I've defined a PreferenceActivity with a nice layout including a ListPreference object for the user to select a bluetooth device. I'm having trouble dynamically populating the list. I would like to populate ListPreference with values from an array adapter (which I'll create and populate with relevant bluetooth device names). If this were a spinner View, I could just call setAdapter(). However with the ListPreference object I can't figure out how to attach an adapter (findviewByID won't cast from View To ListPreference, so I can't even get a handle to the object). I would like to attach an adapter and then populate the adapter with values, which in turn would populate the ListPreference with values.

View 3 Replies View RelatedAndroid :: Looking For List Adapter Pattern
Nov 15, 2010I have a custom layout with a lot of Views. Currently, I build the entire view hierarchy in the on Create, though I stream the actual work in small batches. This works OK up to about 1000 Views and then performance degrades a little. Obviously, I'd like to use the List Adapter pattern and only generate the parts of the View hierarchy that are visible on the screen. My parent View, however, is not (and cannot be) any of the existing List View types. My question, then, is how do the List View types interact with a List Adapter to limit the number of Views necessary to represent a big list? More broadly, is there a pattern out there for extending a Linear Layout to create special List Views?

Nov 5, 2010I have been playing around with a LazyList code sample which is pretty neat for displaying images in a safe and non-memory-hogging way. It uses a very simple mechanism of displaying images based on a list that exists within the class file.
Example:
CODE:...........
I am trying to load these values from an index file that is downloaded to the SD card, and then loaded from it. Here is the code that loads the index file and simply displays it as a Toast message (this works fine).
PULL FILE FROM SD CARD

What I am struggling with is how to take this string that is being loaded from the SD card and pass it into the list adapter.
The code presently looks like this:

I am trying to reload or refresh that same adapter using the values I pulled from the SD card file, presently called "readString".
Can anyone give me some pointers? I am leaving out the code that I created that doesn't work ... because I don't think I am handling this at all correctly. Also - go easy on my, I am a complete newbie to all of this. :-)
Here is my what I am trying to do. Simply copy and paste the working code where I want it. I know it's not that simple, but I am having a hard time reconstructing it properly. Here is my edited code ...

View 1 Replies View RelatedAndroid :: Filtered List View With Custom Adapter Not Updated
Mar 25, 2010I have a ListView with a custom Adapter that extends ArrayAdapter. It's ArrayAdapter of Type Artist. (There are about 1200 artists in my list). Artist is a very small class that has a name and an id. The Artist Class has toString() overridden to return just the name. I have an EditText. The EditText has an TextChangeListener where I call .getFilter().filter(chars, callback) on my adapter. In the Filter.Filterlistener().onComplete() callback i print the count and it looks really good. As i type the count decreases. So it seams everything works as advertised, but the List stays the same. I tried to call artistAdapter.notifyDataSetChanged() to force the list to redraw, but nothing happens. [see 2.)]. I am tinkering around for days now! I am desperate. Hopefully someone can have a look on my code and tell me what I am doing wrong! How can I force the list to be redrawn?
Here is what I have done:
1.) Defined a ListView and an EditText like this:
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_search_text"
android:layout_width="fill_parent"
android:layout_height="35dip"
android:layout_below="@id/header">
</EditText>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/list_search"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
</ListView>
2.) Setup my ListView in the Activities onCreate():
private ListView listView = null;
private ArtistAdapter artistAdapter = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_artists);
artistAdapter = new ArtistAdapter(this, R.layout.row, list); // 'list' is an ArrayList<Artist>
listView = (ListView) findViewById(R.id.list_search);
listView.setAdapter(artistAdapter);
listView.setFastScrollEnabled(true);
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> av, View v, int position, long id) {
// do something } });
EditText txtSearch = (EditText) findViewById(R.id.list_search_text); txtSearch.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable arg0) { }
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
public void onTextChanged(CharSequence chars, int start, int before, int count) {
artistAdapter.getFilter().filter(chars, new Filter.FilterListener() {
public void onFilterComplete(int count) {
Log.d(Config.LOG_TAG, "filter complete! count: " + count);
artistAdapter.notifyDataSetChanged();
}});
}});
}
3.) This is my ArtistAdapter in short. I added an remove() and add() method:
public class ArtistAdapter extends ArrayAdapter<Artist> implements SectionIndexer {
private List<Artist> items;
/* other stuff like overridden getView, getPositionForSection,
getSectionForPosition and so on */
@Override
public void remove(Artist object) {
super.remove(object);
items.remove(object);
}
@Override
public void add(Artist object) {
super.add(object);
items.add(object);
} }
4.) My artist has also the toString() overridden:
public class Artist implements Comparable<Artist> {
public String uid;
public String name;
public Artist(String id, String name) {
this.uid = id;
this.name = name; }
public int compareTo(Artist another) {
return this.name.compareToIgnoreCase(another.name);
}
@Override
public String toString() {
return this.name;
} }
