[英]Android, GridView and onTouchListener
My application have three pages (three tabs) and I want to switch beetween two gridviews by moving finger horizontaly. 我的应用程序有三个页面(三个选项卡),我想通过水平移动手指在两个gridview之间切换。 The touch code works fine but I can't click anymore on the grid items!
触摸代码可以正常工作,但是我无法再单击网格项! I use the method onItemClickListener (onClickListener don't works on Gridview) but the grid item is not clicked.
我使用方法onItemClickListener(onClickListener在Gridview上不起作用),但是未单击网格项。 Thanks for your help!
谢谢你的帮助!
The code is : 代码是:
myGrid.setOnTouchListener(this);
myGrid.setOnItemClickListener(this);
....
public boolean onTouch(View v, MotionEvent event) {
int eventaction = event.getAction();
switch (eventaction) {
case MotionEvent.ACTION_DOWN:
xStart = event.getX();
break;
case MotionEvent.ACTION_UP:
xEnd = event.getX();
if (xEnd - xStart > 20){
//switch to previous tab
}
if (xEnd - xStart < -20){
//switch to next tab
}
return true;
default:
break;
}
return true;
}
What view is that onTouch code in? 该onTouch代码在什么视图中? You could try changing that last
return true
to return false
so that if the action wasn't a motionevent, the event is not consumed by the view. 您可以尝试将最后一个
return true
更改为return false
以便如果该动作不是运动事件,则视图不会使用该事件。
