我有一个小部件,当action android.media.RINGER_MODE_CHANGED
发生时,我必须更新该小部件。我有以下广播接收器:
public void onReceive(Context context, Intent intent) {
AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context.getApplicationContext());
ComponentName thisWidget = new ComponentName(context.getApplicationContext(), ExampleAppWidgetProvider.class);
int[] appWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
if (appWidgetIds != null && appWidgetIds.length > 0) {
for (int widgetId : appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context
.getApplicationContext().getPackageName(),
R.layout.widget1);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
}
以下是关于我的小部件的代码:
这是我的小部件的代码:
public class ExampleAppWidgetProvider extends AppWidgetProvider {
DateFormat df = new SimpleDateFormat("hh:mm:ss");
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
for (int i = 0; i < N; i++) {
int appWidgetId = appWidgetIds[i];
//my pudate widget code
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
}
<receiver android:name=".ExampleAppWidgetProvider" android:label="demo widget">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget1_info" />
</receiver>
我的问题是,即使我从广播接收器执行指令appWidgetManager.updateAppWidget(widgetId, remoteViews);
,小部件中的更新方法也不会被执行。有人知道为什么吗?
