如何以编程方式引发的Android触摸事件？
问题描述：
我想触发触摸事件是这样的：
I would like to trigger a touch event like this:
第一手指触摸向下在（0.50％）的画面的画面和滑动到（50％，50％），以及出口（移动至手指离开画面）
First the finger is touch down at the (0,50%) of the screen and slide to the (50%,50%) of the screen, and exit (move the finger off the screen)
我已经发现了一些事情是这样的：
I have found some thing like this:
MotionEvent event = MotionEvent.obtain(downTime, eventTime, action, x, y, pressure, size, metaState, xPrecision, yPrecision, deviceId, edgeFlags);
onTouchEvent(event);
然而，如何效仿上述情况？我需要创建2的事件吗？ onTouchDown，onMove等....？感谢您的帮助。
However, how to emulate the above case? Do I need to create 2 event ? onTouchDown , onMove etc.... ? Thanks for helping.

// 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);
