[英]MotionEvent Action_Up issues on passing event
I have a top(transparant) view over my appliction. 我对自己的申请有一个顶视图。
this is supposed to catch a Long press of 5 seconds and open a menu . 长按5秒并打开菜单。 So i implemented an OnTouchListener .
所以我实现了一个OnTouchListener。 like this :
像这样 :
public boolean onTouch(View v, MotionEvent event)
{
long downtime = 0;
long eventt = 0;
boolean returnvalue = false;
switch (event.getAction() & MotionEvent.ACTION_MASK)
{
case MotionEvent.ACTION_DOWN:
eventt = event.getEventTime();
returnvalue = true;
break;
case MotionEvent.ACTION_UP:
downtime = event.getDownTime();
if (eventt - downtime > 5000)
{
Main.changePlayerDialog.show();
returnvalue = true;
}
else
{
returnvalue = false;
//return false;
}
break;
default:
break;
}
return returnvalue;
}
});
now , for the 5 second touch and release this works just fine. 现在,对于5秒钟的触摸和释放,效果很好。 however , when its less then 5 ,I return false.
但是,当它小于5时,我返回false。 The MotionEvent however isn't passed down to other views beneath it !
但是,MotionEvent不会传递到其下的其他视图! so all buttons and such of underlying views are now 'disabled' ...
所以所有按钮以及诸如此类的基础视图现在都被“禁用”了...
If i return false straightaway everything works fine... but then the ACTION_UP doesn't trigger anymore if a underlying button has been triggered. 如果我返回错误的结果,一切都很好...但是,如果已触发基础按钮,则ACTION_UP不会再触发。 (seems logical, event has been handled somewhere else).
(似乎合乎逻辑,事件已在其他地方处理)。
how can i fix this ? 我怎样才能解决这个问题 ?
Have you tried returning : 您是否尝试过返回:
return super.onTouch(v, event);
? ?
--- Edit -编辑
Well, if you do so : 好吧,如果您这样做:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="coucou"
android:id="@+id/button" />
<LinearLayout android:id="@+id/linear"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</RelativeLayout>
And add onTouch on linear layout and on click on button, the button will never catch the event... 并在线性布局上添加onTouch并单击按钮,该按钮将永远不会捕获事件...
