Hi, I have an app widged which basically has a textview. I also have
an activity which displays a textview from string created within. Now
i have a button in Activity 1 which onClick will send data (string to
appWidget class) I tried putExtra and getExtra methods and also Shared
preferences method, im little confused to use which first!
Here are some inputs from me for more clarity.
Activity1:
final String addwidget =
((TextView)findViewById(R.id.verse)).getText().toString();
Intent widgetIntent = new Intent(MyScheduledActivity.this,
MainWidget.class);
widgetIntent.putExtra("widgetVerse", addwidget);
AppWidget:
public class MainWidget extends AppWidgetProvider {
RemoteViews views;
public static String verseFromFav;
private Bundle getVerseData;
@Override
public void onReceive(Context context, Intent intent) {
getVerseData = intent.getExtras();
verseFromFav = getVerseData.getString("widgetVerse");
super.onReceive(context, intent);
}
@Override
public void onUpdate(Context context, AppWidgetManager
appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i=0; i<N; i++) {
views = new
RemoteViews(context.getPackageName(),R.layout.widget_layout);
if(verseFromFav == null){
verseFromFav = "no verse";
}
views.setTextViewText(R.id.widgetVerse,
verseFromFav);
ComponentName thisWidget = new ComponentName(
context,
MainWidget.class );
AppWidgetManager.getInstance( context ).updateAppWidget( thisWidget,
views );
appWidgetManager.updateAppWidget(appWidgetIds,
views);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
}
(THE APP WIDGET SHOWS "no verse" WHICH READS NULL)
Can any one help me with a basic idea on how to display the string
here. please. thanks in advance.
