启动活动的Android简单小部件
||
嗨，我之前从未使用过小部件，但是我想做的是创建一个非常简单的小部件，我基本上想制作一个只有图标的，只有一个图像设置为背景，没有文本的1 by 1小部件。没有什么只是一个小图标，当我按下图标时，我想打开一个活动。基本上，我想以小部件形式在应用程序抽屉中创建第二个图标，以打开另一个活动而不是主要活动。
任何帮助是极大的赞赏

public class WidgetProvider extends AppWidgetProvider { @Override 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]; Intent intent = new Intent(context, ClassToLaunchHere.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); views.setOnClickPendingIntent(R.id.widget, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } } }细屠截殴些

然后添加onUpdate和onReceive@Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { ComponentName thisWidget = new ComponentName(context, DigitalClock.class); RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock); for (int widgetId : appWidgetManager.getAppWidgetIds(thisWidget)) { remoteViews.setOnClickPendingIntent(R.id.imageView, getPendingSelfIntent(context, YOUR_AWESOME_ACTION)); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } } @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub super.onReceive(context, intent); if (YOUR_AWESOME_ACTION.equals(intent.getAction())) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.digital_clock); ComponentName watchWidget = new ComponentName(context, DigitalClock.class); appWidgetManager.updateAppWidget(watchWidget, remoteViews); Intent ntent = new Intent(context, MainActivity.class); ntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(ntent); //Toast.makeText(context, YOUR_AWESOME_ACTION, Toast.LENGTH_SHORT).show(); } } protected PendingIntent getPendingSelfIntent(Context context, String action) { Intent intent = new Intent(context, getClass()); intent.setAction(action); return PendingIntent.getBroadcast(context, 0, intent, 0); }<activity android:name=\".MainActivity\"> <intent-filter> <action android:name=\"android.intent.action.MAIN\" /> <category android:name=\"android.intent.category.LAUNCHER\" /> </intent-filter> </activity>
