禁用button的方法

在AppWidget开发中我们可以使用button，但是却不能是buttondisable为什么呢

RemoteViews不能控制一个button可用和不可用的状态，但是可以控制它的显示与隐藏

 然后呢

<ButtonAndroid:idButtonAndroid:id="@+id/startbutton"
android:text="Start"
android:visibility="visible">
</Button> 
<Buttonandroid:idButtonandroid:id="@+id/startbutton_disabled"
android:text="Start"
android:clickable="false" 
androidandroid:textColor="#999999"
android:visibility="gone">
</Button> 
<Buttonandroid:idButtonandroid:id="@+id/stopbutton"
android:text="Stop"
android:visibility="gone">
</Button> 
<Buttonandroid:idButtonandroid:id="@+id/stopbutton_disabled"
android:text="Stop"
android:clickable="false" 
androidandroid:textColor="#999999"
android:visibility="visible">
</Button>

  当点击startbutton的时候 

RemoteViews remoteView=newRemoteView(context.getPackageName(),R.layout.widget); 
 remoteView.setViewVisibility(R.id.startbutton,View.GONE); 
 remoteView.setViewVisibility(R.id.startbutton_disabled,View.VISIBLE);  
 remoteView.setViewVisibility(R.id.stopbutton,View.VISIBLE); 
 remoteView.setViewVisibility(R.id.stopbutton_disabled,View.GONE);
 AppWidgetManager.getInstance(context).updateAppWidget(AppWidgetId,remoteView);

 当点击stopbutton的时候 

RemoteViewsremoteView=newRemoteViews(context.getPackageName(),R.layout.widget); 
remoteView.setViewVisibility(R.id.startbutton,View.VISIBLE); 
remoteView.setViewVisibility(R.id.startbutton_disabled,View.GONE); 
remoteView.setViewVisibility(R.id.stopbutton,View.GONE);  
remoteView.setViewVisibility(R.id.stopbutton_disabled,View.VISIBLE); 
AppWidgetManager.getInstance(context).updateAppWidget(AppWidgetId,remoteView);

其实通过一个android:clickable="false"，还有buuton的隐藏转换造成了视觉的欺骗
