Processing more than one button click at Android Widget
android, widget
Solution
That works, our Widget class that extends `AppWidgetProvider`:
public class ExampleProvider extends AppWidgetProvider {
// our actions for our buttons
public static String ACTION_WIDGET_REFRESH = "ActionReceiverRefresh";
public static String ACTION_WIDGET_SETTINGS = "ActionReceiverSettings";
public static String ACTION_WIDGET_ABOUT = "ActionReceiverAbout";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main_layout);
Intent active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_REFRESH);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_refresh, actionPendingIntent);
active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_SETTINGS);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_settings, actionPendingIntent);
active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_ABOUT);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_about, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_WIDGET_REFRESH)) {
Log.i("onReceive", ACTION_WIDGET_REFRESH);
} else if (intent.getAction().equals(ACTION_WIDGET_SETTINGS)) {
Log.i("onReceive", ACTION_WIDGET_SETTINGS);
} else if (intent.getAction().equals(ACTION_WIDGET_ABOUT)) {
Log.i("onReceive", ACTION_WIDGET_ABOUT);
} else {
super.onReceive(context, intent);
}
}
...
And `AndroidManifest.xml` where we must register our actions:
<receiver android:name="ExampleProvider">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_REFRESH"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_SETTINGS"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_ABOUT"/>
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_info"/>
</receiver>
</application>
Problem
I saw this topic and implement `IntentService` as describes, but what if I want more than one button? How can I distinguish button from each other? I'm trying to `setFlags`, but cannot read it at `onHandleIntent()` method: ``` public static class UpdateService extends IntentService { ... @Override public void onHandleIntent(Intent intent) { ComponentName me = new ComponentName(this, ExampleProvider.class); AppWidgetManager manager = AppWidgetManager.getInstance(this); manager.updateAppWidget(me, buildUpdate(this)); } private RemoteViews buildUpdate(Context context) { RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.main_layout); Intent i = new Intent(this, ExampleProvider.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_refresh, pi); i = new Intent(this, ExampleProvider.class); pi = PendingIntent.getBroadcast(context, 0, i, 0); updateViews.setOnClickPendingIntent(R.id.button_about, pi); return updateViews; } } ``` At this little piece of code I have two `PendingIntent` linked with `setOnClickPendingIntent`, can I distinguish this intent for different actions and processing? Thanks for the help!
