Android的，GridView和onTouchListener [英] Android, GridView and onTouchListener

问题描述

我的应用程序中有三个页面（三个选项卡），我想通过horizo​​ntaly移动手指beetween 2 GridView的切换。触摸code工作正常，但我不能再点击网格上的物品！我使用的方法onItemClickListener（onClickListener不工作在GridView的），但电网项目不点击。
感谢您的帮助！

在code是：

  myGrid.setOnTouchListener（本）;
myGrid.setOnItemClickListener（本）;
....公共布尔onTouch（视图V，MotionEvent事件）{
    INT eventaction = event.getAction（）;
    开关（eventaction）{
    案例MotionEvent.ACTION_DOWN：
        XSTART = event.getX（）;
        打破;
    案例MotionEvent.ACTION_UP：
        XEND = event.getX（）;        如果（XEND  -  XSTART→20）{            //切换到previous标签
        }
        如果（XEND  -  XSTART＆LT; -20）{
            //切换到下一个标签
        }
        返回true;
    默认：
        打破;
    }
    返回true;
}
 

解决方案

什么观点是，onTouch code吗？你可以尝试改变，去年返回true 到返回false 因此，如果动作不是motionevent，事件不受视图消耗

My application have three pages (three tabs) and I want to switch beetween two gridviews by moving finger horizontaly. The touch code works fine but I can't click anymore on the grid items! I use the method onItemClickListener (onClickListener don't works on Gridview) but the grid item is not clicked. Thanks for your help!

The code is :

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;
}

解决方案

What view is that onTouch code in? 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.
