如何在onTouch方法中取消click事件？

Question

我需要创建一个可以在屏幕上拖动的Button。我已经尝试通过在ACTION_MOVE中调用clickable来将setClickable(false)设置为false，但这不起作用。感谢您提供任何有用的答案。

这是我的onTouch()方法：

@Override
public boolean onTouch(View v, MotionEvent event) {
    switch(event.getAction() & MotionEvent.ACTION_MASK) {
        case MotionEvent.ACTION_DOWN:
            //here is click or drag is not sure. we return false here.
            break;
        case MotionEvent.ACTION_MOVE:
            //here after 2~3 events come. we known it's click or drag( by calculate the distance). question here: if current status is drag, how to cancel the click event? 
            break;
        case MotionEvent.ACTION_CANCEL:
        case MotionEvent.ACTION_UP:
            break;
        default:;
    }
    return false;
}
