本文介绍了如何执行从code onTouch事件?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

使用 myObject.performClick()我可以模拟从code click事件。

对于是否 onTouch 事件这样的事情存在吗?我可以模仿触摸操作从Java code?

修改

这是我的 onTouch 监听器。

  myObject.setOnTouchListener(新View.OnTouchListener(){
        @覆盖
        公共布尔onTouch(查看视图,MotionEvent motionEvent){
            // 做一点事
            返回false;
        }
    });


解决方案

这应该工作,发现这里:How在Android中模拟触摸事件:

  //获取MotionEvent对象
长时间的停机= SystemClock.uptimeMillis();
长EVENTTIME = SystemClock.uptimeMillis()+ 100;
浮动X = 0.0;
浮Y = 0.0;
//元状态列表在这里找到:developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
INT亚状态= 0;
MotionEvent motionEvent = MotionEvent.obtain(
    停机时间,
    EVENTTIME,
    MotionEvent.ACTION_UP,
    X,
    Y,
    亚状态
);//调度触摸事件查看
view.dispatchTouchEvent(motionEvent);

有关得到更多有关MotionEvent对象,这里是一个很好的答案:

编辑:并让您的视图的位置,为 X 坐标,使用:

  INT [] = COORDS新INT [2];
myView.getLocationOnScreen(COORDS);
INT X = COORDS [0];
INT Y = COORDS [1];

Using myObject.performClick() I can simulate click event from the code.

Does something like this exist for onTouch event? Can I mimic touch action from the Java code?

EDIT

This is my onTouch listener.

   myObject.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            // do something
            return false;
        }
    });
解决方案

This should work, found here: How to simulate a touch event in Android?:

// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
    downTime,
    eventTime,
    MotionEvent.ACTION_UP,
    x,
    y,
    metaState
);

// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);

For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?

EDIT: and to get the location of your view, for the x and y coordinates, use:

int[] coords = new int[2];
myView.getLocationOnScreen(coords);
int x = coords[0];
int y = coords[1];
