如何允许单多点触控 [英] How to allow single multitouch

问题描述

我写一个定制的ViewGroup，我只需要使用一根手指的触摸，想要彻底清除多点触控。我曾与其他选项被选中的android：splitMotionEvents =FALSE 的android：windowEnableSplitTouch =FALSE但都没有工作。

I am writing an custom ViewGroup where I need to use only single finger touch and wanted to remove multitouch completely. I have checked with other option android:splitMotionEvents="false" android:windowEnableSplitTouch="false" but both are not working.

修改

@Override
    public boolean onTouchEvent(MotionEvent ev) {

        DragHelper.processTouchEvent(ev);

        return true;
    }

任何建议！

推荐答案

尝试以下把定制的视图code。

Try following code in your custom view.

@Override
public boolean onTouchEvent(MotionEvent event) 
{
    // TODO Auto-generated method stub
    if(event.getPointerCount() > 1) {
        System.out.println("Multitouch detected!");
        return true;
    }
    else
    {
        return super.onTouchEvent(event);
    }
}
