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.

I want to show a list of items when the user clicks an overlay item on a map. The user should be able to select any of these items and edit them. The list can have many items (more than that can fit in one active screen) therefore it needs to be scrollable

I even tried to subclass TextView to implement my own scroll method, but nothing worked.Are there any ways to achieve that? there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this
View 3 Replies View RelatedOne of my activities receives some data.I want to obtain a layout like the one for the "contacts" app, which has 1 contact on each row and clicking a row you pass to another activity which shows the details.
What do I need to create the "list" layout?
Are those rows simply TextViews or what else?
How do I generate the rows at runtime into the layout?
If it is too long to write down some code, just tell me what I need and I'll check by myself.

View 2 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?
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

<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"?>

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();
} } );

The ListView contents are managed by an enhanced ArrayAdapter.
When 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?"
