Android appwidget将其他小部件变成添加的小部件＆第二个小部件不会工作？

我正在制作一个有2个小部件的android应用程序。我有1个小部件设置和工作，第二个小部件在小部件列表&中正确加载，但是：Android appwidget将其他小部件变成添加的小部件＆第二个小部件不会工作？

如果我在添加小部件2时屏幕上已经有小部件1，则这两个小部件都将更改为小部件2 。如果我有一个小部件2和一个小部件1，并添加一个小部件2，它们全部更改为小部件2.同样的情况发生，如果我添加小部件1 - 它们全部更改为小部件1.

此外，部件2被点击，即使我用几乎相同的代码窗口小部件1.

wi dgetstuff.xml（用于小工具1）：

<?xml version="1.0" encoding="utf-8"?> 
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" android:minHeight="40dp" android:minWidth="40dp" android:initialLayout="@layout/widget_layout"> 


</appwidget-provider>

任何人都可以告诉我问题是什么吗？我通过这个做我的螺母在试图弄明白:(

您还没有利用了onUpdate PARAM int[] appWidgetIds的。

你应该循环，任何代码适用于每个人。此刻的你是不告诉它更新哪个小部件，也不尝试和更新超过一个小部件

下面的例子，注意N上的循环。子方法也使用小部件的id，它从onUpdate。

@Override 
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { 
     final int N = appWidgetIds.length; 

     Log.d(LOG_TAG, "Updating Example Widgets."); 

     // 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, WidgetExampleActivity.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.widget1); 
      views.setOnClickPendingIntent(R.id.button, pendingIntent); 
      // Tell the AppWidgetManager to perform an update on the current app 
      // widget 
      appWidgetManager.updateAppWidget(appWidgetId, views); 


      // Update The clock label using a shared method 
      updateAppWidget(context, appWidgetManager, appWidgetId); 
     } 
    } 

    public static void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) { 
     String currentTime = df.format(new Date()); 

     RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.widget1); 
     updateViews.setTextViewText(R.id.widget1label, currentTime); 
     appWidgetManager.updateAppWidget(appWidgetId, updateViews); 
    }
