Android的顯示圖標

我無法顯示Android設備的鎖定屏幕上的小部件，我的代碼：Android的顯示圖標

package com.example.widgetapp; 

    import android.annotation.SuppressLint; 
    import android.app.PendingIntent; 
    import android.appwidget.AppWidgetManager; 
    import android.appwidget.AppWidgetProvider; 
    import android.content.ActivityNotFoundException; 
    import android.content.ComponentName; 
    import android.content.Context; 
    import android.content.Intent; 
    import android.net.Uri; 
    import android.view.WindowManager; 
    import android.widget.RemoteViews; 
    import android.widget.Toast; 

public class MainActivity extends AppWidgetProvider { 

    // private static final String ACTION_CLICK = "ACTION_CLICK"; 

    @SuppressLint("NewApi") 
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
       int[] appWidgetIds) 
    { 


     ComponentName thisWidget = new ComponentName(context, 
        MainActivity.class); 
     int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); 
     for (int widgetId : allWidgetIds) { 

        try { 
//     getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
//     getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); 
         Intent intent = new Intent("android.intent.action.MAIN"); 
         intent.addCategory("android.intent.category.LAUNCHER"); 

         intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
         intent.setComponent(ComponentName.unflattenFromString("com.example.rage/com.example.rage.RageActivity")); 

         Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"+198)); 
         callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

         //remoteViews.setOnClickFillInIntent(widgetId, callIntent); 

         PendingIntent pendingIntent = PendingIntent.getActivity(
          context, 0, intent, 0); 
         PendingIntent pendingIntent1 = PendingIntent.getActivity(
           context, 0, callIntent, 0); 
         RemoteViews views = new RemoteViews(context.getPackageName(), 
           R.layout.activity_main); 
//     views.setOnClickFillInIntent(widgetId, intent); 
//     views.setOnClickFillInIntent(widgetId, callIntent); 

        // context.startActivity(intent); 
        // context.startActivity(callIntent); 

         views.setOnClickPendingIntent(R.id.button1, pendingIntent1); 
         views.setOnClickPendingIntent(R.id.button2, pendingIntent); 

        appWidgetManager.updateAppWidget(widgetId, views); 

        } catch (ActivityNotFoundException e) { 
          Toast.makeText(context.getApplicationContext(), 
            "There was a problem loading the application: ", 
            Toast.LENGTH_SHORT).show(); 

        } 
     } 

}

你把'keyguard'放到你的'android：widgetCategory'中了嗎？ –

嘗試補充說：「機器人：widgetCategory =」 home_screen |鍵盤保護」到提供XML

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" 
    android:initialLayout="@layout/my_widget_layout" 
    android:minHeight="40dp" 
    android:minWidth="40dp" 
    android:resizeMode="horizontal|vertical" 
    android:widgetCategory="home_screen|keyguard" > 
</appwidget-provider>
