アンドロイドウィジェットでonclicklistnerを設定する方法は？

Question

MyCollectionWidgetProvider

CollectionWidgetがAppWidgetProviderを拡張

パブリッククラス{ プライベート静的最終列MyOnClick = "myOnClickTag"。

void updateAppWidget(Context context, AppWidgetManager appWidgetManager, 
        int appWidgetId) { 
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.collection_widget); 

// views.setTextViewText（R.id.appwidget_text、widgetText）;

// Set up the collection 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) { 
     setRemoteAdapter(context, views); 
    } else { 
     setRemoteAdapterV11(context, views); 
    } 
    // Instruct the widget manager to update the widget 
    appWidgetManager.updateAppWidget(appWidgetId, views); 

    views.setOnClickPendingIntent(android.R.id.text1, 
      getPendingSelfIntent(context, MyOnClick)); 



} 

@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); 
    } 
    super.onUpdate(context, appWidgetManager, appWidgetIds); 
} 

@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 
} 

/** 
* Sets the remote adapter used to fill in the list items 
* 
* @param views RemoteViews to set the RemoteAdapter 
*/ 
@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH) 
private static void setRemoteAdapter(Context context, @NonNull final RemoteViews views) { 
    views.setRemoteAdapter(R.id.widget_list, 
      new Intent(context, WidgetService.class)); 
} 

/**

*/ 
@SuppressWarnings("deprecation") 
private static void setRemoteAdapterV11(Context context, @NonNull final RemoteViews views) { 
    views.setRemoteAdapter(0, R.id.widget_list, 
      new Intent(context, WidgetService.class)); 


} 
protected PendingIntent getPendingSelfIntent(Context context, String action) { 
    Intent intent = new Intent(context, getClass()); 
    intent.setAction(action); 
    return PendingIntent.getBroadcast(context, 0, intent, 0); 
} 

@Override 
public void onReceive(Context context, Intent intent) { 
    super.onReceive(context, intent); 

    if (MyOnClick.equals(intent.getAction())){ 
     Toast.makeText(context, "clicked", Toast.LENGTH_SHORT).show();  } 
} 

}

WidgetDataProvider

パブリッククラスWidgetDataProviderは、ブロードキャストレシーバクラス、捕捉においてRemoteViewsService.RemoteViewsFactory {

List<String> mCollection = new ArrayList<>(); 
Context mContext = null; 

public WidgetDataProvider(Context context, Intent intent) { 
    mContext = context; 
} 

@Override 
public void onCreate() { 
    initData(); 
} 

@Override 
public void onDataSetChanged() { 
    initData(); 
} 

@Override 
public void onDestroy() { 

} 

@Override 
public int getCount() { 
    return mCollection.size(); 
} 

@Override 
public RemoteViews getViewAt(int position) { 
    RemoteViews view = new RemoteViews(mContext.getPackageName(), 
      android.R.layout.simple_list_item_1); 
    view.setTextViewText(android.R.id.text1, mCollection.get(position)); 




    return view; 
} 

@Override 
public RemoteViews getLoadingView() { 
    return null; 
} 

@Override 
public int getViewTypeCount() { 
    return 1; 
} 

@Override 
public long getItemId(int position) { 
    return position; 
} 

@Override 
public boolean hasStableIds() { 
    return true; 
} 

private void initData() { 
    mCollection.clear(); 
    for (int i = 1; i <= 10; i++) { 
     mCollection.add("ListView item " + i); 
    } 
} 

}

を実装しますインテントのエキストラとエキストラに基づいて、更新されたUI変更でRemoteViewを再度作成します。
