如何通過點擊小工具

Question

我WidgetProvider打開的應用程序是這樣的：

package br.com.pedro.widget; 

import android.appwidget.AppWidgetProvider; 

public class MyWidgetProvider extends AppWidgetProvider { 

} 

如何顯示，顯示佈局和點擊後進入我的主類的窗口小部件？

這裏將MainActivity替換爲您想要打開的活動。

@Override 
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { 
     final int N = appWidgetIds.length; 
     Toast.makeText(context, "Touched view ", Toast.LENGTH_SHORT).show(); 
     Log.i("ExampleWidget", "Updating widgets " + Arrays.asList(appWidgetIds).size()); 
     // Perform this loop procedure for each App Widget that belongs to this 
     // provider 
     for (int i = 0; i < N; i++) { 
      int appWidgetId = appWidgetIds[i]; 

      // Create an Intent to launch ExampleActivity 
      Intent intent = new Intent(context, MainActivity.class); 
      PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); 

      // Get the layout for the App Widget and attach an on-click listener 
      // to the button 
      RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout); 
      views.setOnClickPendingIntent(R.id.button, pendingIntent); 

      // Tell the AppWidgetManager to perform an update on the current app 
      // widget 
      appWidgetManager.updateAppWidget(appWidgetId, views); 
     } 
    }
