Android的触摸起来不工作 [英] Android Touch UP not working

问题描述

即时消息还挺坚持了这个项目的Andr​​oid即时通讯试图弄清楚这是为什么不工作，但我没有idea.This是顺便的自定义视图，以防万一。

问题是这样的事件ACTION_DOWN是可以正常使用即时得到控制台调试触摸1和触摸2，但ACTION_UP，ACTION_CANCEL或默认：不工作我不能算出这个所以任何帮助将是非常美联社$ pciated p $谢谢

这里是IM调用doTouch功能

 公共布尔onTouchEvent（MotionEvent事件）
        {
            thread.doTouch（事件）;
            返回super.onTouchEvent（事件）;
        }
 

解决方案

它看起来像你的问题是你要处理的 onTouchEvent 触摸事件的方式。你需要，如果你想处理触摸事件从 onTouchEvent 返回true。所以，如果你得到一个 ACTION_DOWN 和 onTouchEvent 返回false，系统将不会向您发送相关的，直到更多的触摸事件接下来的 ACTION_DOWN 事件。

不知道正是你所用的触摸事件做什么，我不能给你一个解决方案，一定会为你的情况下工作，但如果你想获得比 ACTION_DOWN <之外的任何触摸事件/ code>您将需要从 onTouchEvent 。

im kinda stuck with this project in android im trying to figure out why this is not working but i have no idea.This is By the way a custom view just in case.

The problem is this the event ACTION_DOWN is working perfectly im getting the console debug "Touching 1" and "Touching 2" but ACTION_UP,ACTION_CANCEL or default: are not working i cant figure this out so any help would be really appreciated thank you

        public void doTouch(MotionEvent event)
        {
            int action = event.getAction();

            float x = event.getX();
            float y = event.getY();

            switch(action)
            {
            case MotionEvent.ACTION_DOWN:
                if(x < 125 && y < 125){
                    for(AnimatedSprite a:mSprites)
                    {
                        if(a.getID() == 1)
                        {
                            a.AdvanceToFrame(0);
                            touching = true;
                            System.out.println("Touching 1");
                            //touch_obj1 = true;
                        }
                    }
                }
                else if(x > getWidth()-125 && y > getHeight()-125)
                {
                    for(AnimatedSprite a:mSprites)
                    {
                        if(a.getID() == 2)
                        {
                            a.AdvanceToFrame(1);
                            System.out.println("Touching 2");
                            touching = true;
                            //touch_obj2 = true;
                        }
                    }
                }
                else
                {
                    touching = false;
                }
                break;
                case MotionEvent.ACTION_CANCEL:
                case MotionEvent.ACTION_UP:

                    System.out.println("Touch UP");
                    touching = false;
                    break;

                default:
                    System.out.println("NOT Touching");
                    touching = false;
                break;
            }
        }

here is where im calling the doTouch function

public boolean onTouchEvent(MotionEvent event)
        {
            thread.doTouch(event);
            return super.onTouchEvent(event);
        }

解决方案

It looks like your problem is the way you are handling touch events in onTouchEvent. You need to return true from onTouchEvent if you want to handle touch events. So, if you get an ACTION_DOWN and return false from onTouchEvent the system will not send you any more touch events related until the next ACTION_DOWN event.

Without knowing exactly what you are doing with the touch events, I can't give you a solution that will definitely work for your situation, but if you want to receive any touch events other than ACTION_DOWN you will need to return true from onTouchEvent.
