我创建了一个显示数字时钟的简单 appwidget,并为该时钟设置了 PendingIntent。(即)当用户点击 textview 时,拨号盘被打开。它完美地工作。但是,当我打开一些应用程序(例如 Car Home)然后从 Car Home 退出时,我的主屏幕只会闪一下。我的小部件现在进入无响应状态。我不知道我错了。过去 2 天我在谷歌上搜索这个。任何人请帮忙。
爪哇代码:
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
super.onUpdate(context, appWidgetManager, appWidgetIds);
context.startService(new Intent(UpdateService.ACTION_UPDATE));
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
Intent dial = new Intent();
dial.setAction("android.intent.action.DIAL");
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, dial, 0);
remoteViews.setOnClickPendingIntent(R.id.Time, pendingIntent);
for (int i = 0; i < appWidgetIds.length; i++) {
appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews);
}
}
