Android :: ListView On Item Click Listener Not Responding?
Mar 3, 2010I've looked everywhere for a solution to this, but I can't figure out how to implement it. My OnItemClickListener was disabled somehow on my ListView rows, because I have an ImageButton in the row layout, which takes over the focus. There have been numerous questions I've found, but none of them have gotten me anywhere. I've checked this question, but I couldn't really make heads or tails of it. I just need a way to get the rows clickable so that I can detect when a row is pressed. Long press and focus work fine.

Sep 23, 2010I have a ListView and an ExpandableListView inside of a TabActivity. I have overridden the setOnItemClickListener for the ListView. I have 2 tabs and one uses the ListView and the other uses the ExpandableListView. For some reason I cannot click on any of the items in the first ListView.

Oct 5, 2009I have Implemented a custom ListView by extending LinearLayout for every row. Every row has a small thumbnail, a text and a check box. The list view is deployed properly and I can scroll and fling through it without any problems. But The ListView doesn't seem to respond to the setOnItemClickListener() at all, So I had to find a workaround by setting click listener in the getView of the Text inside every row which is obviously creating problem when I am trying to reuse the adapter. Does anyone have a solution?

Android :: List View On Item Click Listener Not Working
Sep 6, 2010What I´m trying to do is to create a list (using a list view) of items (which are views inflated from the same layout) what must be clickable. At first I thought that all I had to do was to add an onItemClickListener to the ListView so if the used clicked on any of the views that composed this Item the listener would react. Well, I was wrong. I´ve tried a lot of things, including setting focus and focusontouchmode off for each of the views that compose the item´s view but it still doesn´t work. Any tips here? Can I archive this result? Oh, also ... this list view is in a dialog and the listener is in the activity that builds the dialog.

I thought only unread articles were supposed to sync but mine just keeps loading all the same crap again, as well as new stuff too.

Android :: Button Click Lost On Widget When Screen Rotated
Nov 22, 2010I have a very simple widget application which consists of a linear layout with a background and an image button. In the AppWidgetProvider on Update method, I register the click of the button to broadcast an intent. When the widget first loads, everything runs fine and the click is captured. The problem occurs when the screen is rotated, and the click is never captured again even if the screen is rotated back. What do I have to do to re-register the click when the screen rotates? below is some segments of code I am using.
AppWidgetProvider
@Override
public void on Receive(Context context, Intent intent)
{super.on Receive(context, intent);
if(intent.getAction().equals("test.CLICK"))
{Closemouthed(context);}}
@Override
public void on Update(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds)final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i]; RemoteViews views=new RemoteViews(context.getPackageName(), R.layout.widget);
Intent click intent=new Intent("test.CLICK");
Pending Intent pendingIntentClick=Pending Intent.getBroadcast(context, 0, click intent, Pending Intent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.change_mode, pendingIntentClick);
SetInitialLayout(context);
appWidgetManager.updateAppWidget(appWidgetId, views);}
super.on Update(context, appWidgetManager, appWidgetIds);}
Manifest
<receiver android:name=".Widget" android:label="@string/widget_name">
<intent-filter>
<action android:name="android.appwidget.action.ACTION_APPWIDGET_CONFIGURE" />
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
<action android:name="test.CLICK" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_mode_switcher" />
