Question

在我的Android应用程序中，我有3个全屏幕ImageButtons（水平在LinearLayout内部），我隐藏了状态栏（全屏应用程序）

问题在于，当我向下滑动以显示状态栏时，顶部的ImageButton被点击，我尝试检测点击次数，因此我禁用了按钮的功能，如果它是滑动而不是像这样的点击

@Override
public boolean onTouchEvent(MotionEvent event)
{
    switch (event.getAction())
    {
        case MotionEvent.ACTION_DOWN :
            y1 = event.getY();

            i=0;

            break;
        case MotionEvent.ACTION_UP:
            y2 = event.getY();

            float deltaY = y2-y1; 
            if(deltaY < 10 && deltaY > -10)
            {
                flag=true;
            }
            else
            {
                flag=false;
            }
            break;
    }
    return super.onTouchEvent(event);
}

但它似乎不起作用。

非常感谢任何帮助，谢谢你。

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_birthday);


    }

    public void speech(View v)

                float Delta = x2-x1;

                //if on actionUp, the distance is big == swipe 
                if(Delta < 5 && Delta(-5))
                {

                }
                else
                {

                }
                break;
        }
        return super.onTouchEvent(event);
    }



}

Answer 1

onTouchEvent如果您使用了此操作则返回true，如果您没有，则返回false。

所以，你应该这样 -

@Override
public boolean onTouchEvent(MotionEvent event)
{
    switch (event.getAction())
    {
        case MotionEvent.ACTION_DOWN :{
            //something
            return true;
        }
        case MotionEvent.ACTION_UP: {
            //something else
            return true;
        }
    }
    //some other event, let system handle it
    return super.onTouchEvent(event);
}
