如何从代码执行onTouch事件？ [英] How to perform onTouch event from code?

问题描述

使用 myObject.performClick（）我可以从代码中模拟点击事件。

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

对于 onTouch 事件，会有类似的东西吗？我可以模仿Java代码中的触摸操作吗？

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

编辑

我的 onTouch 监听器。

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

推荐答案

这应该工作，在这里找到：如何在Android中模拟触摸事件？：

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);

有关获取MotionEvent对象的更多信息，以下是一个很好的答案：Android：如何创建MotionEvent？

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

编辑：要获取视图的位置，对于 x 和 y 坐标，请使用：

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];
