Android ImageView onClick event on Widget

如何才能知道或捕获ImageView onclicklistener？Android ImageView onClick event on Widget

public class AppWidget extends AppWidgetProvider{ 
    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, ShowActivity.class); 
      PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); 
      RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout); 
      views.setOnClickPendingIntent(R.id.imageView1, pendingIntent); 
      appWidgetManager.updateAppWidget(appWidgetId, views); 
     } 
    } 
}

上面的代码，当点击ImageView时，意图ShowActivity.class。但是我真正想要的是当点击ImageView时，我想显示“Toast”消息而不需要任何活动。

它会显示ü想excatly什么事：

Intent intent = new Intent(context, ShowActivity.class); 
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);   
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME))); 
PendingIntent pendIntent = PendingIntent.getActivity(context, 0,intent, PendingIntent.FLAG_UPDATE_CURRENT); 
RemoteViews views = new RemoteViews(context.getPackageName(),R.layout.widget_layout); 
views.setOnClickPendingIntent(R.id.image1, pendIntent); 
appWidgetManager.updateAppWidget(appWidgetId, views);

我很困惑，“在哪里敬酒味精会显示上面的代码？” – ppshein 2013-04-25 06:06:09

您是否尝试过ClickClickListener？

ImageView img = (ImageView) findViewById(R.id.img_id); 
img.setOnClickListener(new OnClickListener() { 
@Override 
public void onClick(View v) { 
    Toast.makeText(YourActivityName.this, 
      "My Toast Text", Toast.LENGTH_LONG).show(); 
    } 
});

你写的不是AppWidgetProvider。我的意思是，如何捕捉AppWidgetProvider中的onclicklistener。 – ppshein 2013-04-25 03:09:12

好吧，我明白了，问题并非100％清楚 - “我如何知道或捕获ImageView onclicklistener？” – ebi 2013-04-25 14:36:37
