android - 如何以编程方式触发android中的触摸事件？

Question

我想触发这样的触摸事件:

首先手指在屏幕的 (0,50%) 处触碰并滑动到屏幕的 (50%,50%)，然后退出(将手指从屏幕上移开)

我发现了一些类似的东西:

MotionEvent event = MotionEvent.obtain(downTime, eventTime, action, x, y, pressure, size, metaState, xPrecision, yPrecision, deviceId, edgeFlags);

onTouchEvent(event);

但是，如何模拟上述情况？我需要创建 2 个事件吗？ onTouchDown ， onMove 等....？感谢您的帮助。

Answer 1

// 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);
