I have a custom ListView and I want to redraw a View inside each row under some circumstances. How would I do that in the ListActivity?
But that seems a waste, redrawing the whole listview. Code...

I have a ListView with a Button below it. When I fill the list with more content than the screen size allows, so that the scroll bar appears, the Button is not part of the scrollable area. That is, the Button disappears. How do I make the Button part of the scrollable area? Code...
View 2 Replies View RelatedI wanted to change the divider height dynamically. From whatever I have searched it seems that it is possible through setting divider as part of each item in listview. But I am not very clear with this. So, can someone be more specific as how can one make the divider as part of item in listview?

View 2 Replies View RelatedI have a widget set up and it displays properly in both portrait and landscape when added to each. But when I change orientation it has the problem "Problem Loading Widget". I delete this, re-add the widget, and it displays correctly. Thus, my widget can support both portrait and landscape but it doesn't survive an orientation switch. What am I missing? Do I need to redraw the widget when orientation is changed? Doesn't it do this automatically? Do I need to call onUpdate() somehow?

I am having a bit of trouble with my current application. With a button at the beginning of my app, I send out Intents for two activities, one gets a camera object, and starts a preview screen. On top of that, in a separate layout, there is an activity with a translucent view, which shows a resource image (the user is trying to get the image he is actually taking to align with the translucent image) and a couple of textviews displaying a target phone orientation as well as the user's current phone orientation.
when I update the text value of one of my text views in my onSensorChanged() field, the system constantly reallocates 1.22MB and garbage collects it. I can only assume that this is because it is redrawing the entire layout with the translucent image and the text fields, because if I remove the view containing the translucent image from the layout, my text field updates 10x quicker and I don't have ridiculous heap growing / garbage collecting. I am wondering how to go about getting the text fields to update without redrawing the entire surface. I am very new to UI design, and this code was written by someone else before I took over the project, so I don't understand much of what is going on in the custom view he wrote to take care of the translucent image -- called MyView. I will post the code for the layout as well as the MyView code below.................................
It seems that my home screen takes a while to load anytime I switch to it. Noticeably lagging are the widgets on that screen (GMail Unread Count x2, Agenda Widget, power control). I figure this is because these widgets are killed when using other programs to free memory. Is this the case? If so, is there anything I can do to change that since I am now rooted?

I have a LinearLayout layout with a ListView in it. I've made the android:background of the LinearLayout (I've also tried it on the ListView) be an image that I would like for my background.
This works fine enough. However, when I start scrolling through the ListView, the background often disappears and becomes black. If I move it around some more I may be able to get it to appear again. It would seem that Android is drawing over, or perhaps painting what's behind my background onto the items.

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:

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.

I have an ExpandableListView that I want to populate with my custom views of type NoteView. NoteView extends LinearLayout and contains two buttons and a checkbox. I have almost everything working, the NoteView's are being populated with backing data, the lists are getting filled, and the buttons are clickable and perform the required tasks.
The problem is the ExpandableListView no longer responds to click/longclick/keypress events at all (other than selecting list items with trackball/DPAD).
I replaced my custom view with a standard TextView and the touch events flowed normally again, so it is almost certainly something I am doing wrong with my custom view or some obscure ListView setting I am overlooking.
Here is my NoteView code and XML Layout. What am I missing?

I want 2 things:
When i move with arrow keys, the item selected changed its background. It's works fine with the actual implementation of selector.
When i press a item, the item changed its background too, but it doesn't work with the actual selector.
I try to set also into the ListView android:listSelector="@drawable/list_selector" but it doesn't work neither.

View 2 Replies View RelatedI think I've tried everything(made focusable:false!!) and I cant capture in anyway the selected checkbox on my list item. Even OnItemClickListener, doesn't respond to any click. How can I retrieve checked checkboxes in my list item? My list item included: image view, 4 textviews and the checkbox. Some code:
this is in my ListActivity class:
final String columns[] = new String[] { MyUsers.User._ID, MyUsers.User.MSG, MyUsers.User.LOCATION }; int[] to = new int[] { R.id.toptext, R.id.bottomtext,R.id.ChkBox, R.id.Location}; Uri myUri = Uri.parse("content://com.idan.datastorageprovider/users"); Cursor cursor = getContentResolver().query(myUri, columns, null, null, null); startManagingCursor(cursor); ListCursorAdapter myCursorAdapter=new ListCursorAdapter(this, R.layout.listitem, cursor, columns, to); this.setListAdapter(myCursorAdapter);
And this is my Custom Cursor adapter class:
public class ListCursorAdapter extends SimpleCursorAdapter { private Context context; private int layout; public ListCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) { super(context, layout, c, from, to); this.context = context; this.layout = layout;
} @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { Cursor c = getCursor(); final LayoutInflater inflater = LayoutInflater.from(context); View v = inflater.inflate(layout, parent, false); return v;
} @Override public void bindView(View v, Context context, Cursor c) { TextView topText = (TextView) v.findViewById(R.id.toptext); if (topText != null) { topText.setText("");
} int nameCol = c.getColumnIndex(MyUsers.User.MSG); String name = c.getString(nameCol); TextView buttomTxt = (TextView) v.findViewById(R.id.bottomtext); if (buttomTxt != null) { buttomTxt.setText("Message: "+name); } nameCol = c.getColumnIndex(MyUsers.User.LOCATION);
name = c.getString(nameCol); TextView location = (TextView) v.findViewById(R.id.Location);
if (locationLinkTxt != null) { locationLinkTxt.setText(name);
}
I've tried many ways. many listeners, can't figure how to capture listener to my checkboxes. The data I am binding to the list items from the database, isn't concerned about the checkbox.. only the textviews. There isn't any connection between the database and the checkbox I have in the list's item.
