Android :: How To Display A Loading - Text While Retrieving Items For A ListView
Jul 26, 2010There are some others applications doing this, like Twitter, Facebook, or even native applications such as Android Market. When you want to display a list of items retrieved from the internet, this looks like a standard way for displaying the user some notification about action in progress. This is a white background screen with an animated spinning wheel and a "Loading..." text. Does somebody know how to do this?. I've been able to do something similar with this code, but i don't like it too much yet.

Android :: Removing Items From ListView/ArrayAdapter Doesn't Work After Text Filtering
Jul 10, 2010I 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 :: ListView Items Not Responding To Tap
May 28, 2010I'm just getting my feet wet with Android and have built a UI that contains a TabHost with three tabs. Each tab is powered by its own Activity. The first Tab contains a listview with a prepopulated set of rows and is built from a custom ArrayAdapter.
The problem I'm running into is that none of the ListView rows are tappable. In other words, when I tap on them there is no orange selection. If I use the scroll ball on my Nexus One it will select, but any touch gestures don't seem to be responding. All the UI is being handled using XML files with a main.xml housing the TabHost -> LinearLayout -> TabWidget/FrameLayout and a nearby_activity.xml file containing my ListView UI
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

Jul 20, 2010I have a listview that's using a custom adapter. I want to dynamically show/remove items from the listview. I've tried everything inside the getView() method in my view adapter. I've tried doing setVisiblity(View.GONE) on the view I'm returning. And it infact doesn't draw the view, but it allocates space for the view and it's just a blank black space.

Android :: Controlling Width Of ListView Items
May 26, 2009I'm trying to make a list that contains elements not necessarily occupying the entire width of the screen, but even if using android:layout_width="wrap_content" on my elements, they always behave as if their width value were set to "fill_parent" instead. If I set a fixed value for the width, e.g. "100px", that value is indeed used, but I just can't get wrap_content to work.
Example simple list item:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="#707"> <TextView android:id="@+id/text1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentTop="true" android:layout_alignParentRight="true"
android:background="#770" android:text="Text1" /> <TextView android:id="@+id/text2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentLeft="true" android:layout_below="@id/ text1"
android:background="#077" android:text="Text2" /> </RelativeLayout>
What am I missing here? How do I accomplish a list item with wrap_content behaviour, i.e., where the width of each RelativeLayout is adapted to the length of the strings in the contained text views?

Android :: Two Selectable Items In Each List In ListView
Dec 16, 2009The 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.
Android :: Editing List Items In ListView

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)));

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(),

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();
} } );

View 2 Replies View RelatedAndroid :: ListView Items Won't Show Focus When Touched
Jun 20, 2010I've got a ListView that works just great, except for this minor annoyance. I can use the trackball/dpad to move up and down my list, and the background changes according to which row has focus. But when I touch the row (click or long click), there's no background change letting me know what's been focused. I've tried setting 'focusable' and 'focusable in touch mode' to true on the rows, but it still doesn't work.
Just in case it matters somehow:
I am setting onClickListeners for each row. The row is comprised of LinearLayouts, TextViews, and a single ImageView. Focusable/clickable is 'true' for each row. Have not specified values for these on the ListView.
Trackable does act funny. I can only move between rows after touching inside the ListView. If I scroll trackball above the first item, it's impossible for me to scroll back into the list.
