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
因为我们可以利用这个造假
?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
?
