Hi guys,
I am trying to make an appwidget to be displayed when we click a
button.
I am having a simple application which has a button.
When the button is clicked,it will send a broadcast message.
I am implementing an appwidgetprovider class in the same application.
I have overridden the onReceive function in the appwidgetprovider
class as shown below:
@Override
public void onReceive ( Context context,Intent intent ) {
String action = intent.getAction();
String message="";
//String packagename="";
//int appwidgetid;
//String RESULT_OK = "sucessfull";
Log.i("test", "message received");
if( "android.appwidget.action.APPWIDGET_ENABLED".equals (
action ) )
{
//String message;
Toast.makeText( context, "Broadcast sucessfull...",
Toast.LENGTH_LONG).show();
if ( intent.hasExtra(broadcast.MESSAGE)) {
message =
(String)intent.getCharSequenceExtra(broadcast.MESSAGE);
Toast.makeText( context, message,
Toast.LENGTH_LONG).show();
}
ComponentName component;
component = new ComponentName(context,receiver.class);
RemoteViews views = new
RemoteViews(context.getPackageName
(),R.layout.widget_provider);
views.setTextViewText(R.id.message, message);
}
}
}
I am able to see the toast messages but i am not able to see the
appwidget.
In the above code R.layout.widget_provider is the xml file which has
the appwidget-provider tag.
I have also mention this file as the resource file in the android
manifest file.
My questions are:
1.Is this code correct?
2.What should be the second parameter in the instantiation of
"Remoteviews" class?
3.What should be the first parameter in the setTextViewText function?
Please anybody help me on this...
