我這裏看到類似的問題對SO後沒有更新，但似乎在我的情況下工作...的Android - Appwidget與Remoteviews重啓
我創建了一個appwidget與AdapterViewFlipper（簡單ViewAnimator，將兩者之間的動畫或更多的視圖已添加到它）。 appwidget有一個Next按鈕，使用戶可以導航到小部件上的下一個視圖。
這一切工作正常，當我第一次添加appwidget。但是，如果智能手機重新啓動，小部件的Next按鈕不再適用於我的Samsung S4（調用方法onReceive，但未發生，它不會導航到下一個視圖並停留在第一個視圖中）。我必須刪除小部件，並再次添加它，以便它的工作...
我懷疑這是Touchwiz的問題，因爲我在另一部手機（Moto G）上測試它，它工作正常。
下面是我的代碼的一些部分：
的AppWidgetProvider
public class AppWidgetProvider extends AppWidgetProvider {
public static final String NEXT_ACTION = VersionUtil.getPackageName() + ".action.NEXT";
private static final String TAG = DailyAppWidget.class.getSimpleName();
@Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
@Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId, colorValue);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId, int primaryColor) {
Intent intent = new Intent(context, ViewFlipperWidgetService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
// When intents are compared, the extras are ignored, so we need to embed the extras
// into the data so that the extras will not be ignored.
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
// Instantiate the RemoteViews object for the app widget layout.
RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.app_widget);
// open the activity from the widget
Intent intentApp = new Intent(context, MainActivity.class);
intentApp.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intentApp, 0);
rv.setOnClickPendingIntent(R.id.widget_title, pendingIntent);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
rv.setRemoteAdapter(R.id.adapter_flipper, intent);
} else {
rv.setRemoteAdapter(appWidgetId, R.id.adapter_flipper, intent);
}
// Bind the click intent for the next button on the widget
final Intent nextIntent = new Intent(context,
AppWidgetProvider.class);
nextIntent.setAction(AppWidgetProvider.NEXT_ACTION);
nextIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
final PendingIntent nextPendingIntent = PendingIntent
.getBroadcast(context, 0, nextIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
rv.setOnClickPendingIntent(R.id.widget_btn_next, nextPendingIntent);
appWidgetManager.updateAppWidget(appWidgetId, mRemoteViews);
}
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (action.equals(NEXT_ACTION)) {
RemoteViews rv = new RemoteViews(context.getPackageName(),
R.layout.daily_app_widget);
rv.showNext(R.id.adapter_flipper);
int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
Log.e(TAG, "onReceive APPWIDGET ID " + appWidgetId);
AppWidgetManager.getInstance(context).partiallyUpdateAppWidget(
appWidgetId, rv);
}
super.onReceive(context, intent);
}
