如何以编程方式引发的Andr​​oid触摸事件？ [英] How to programmatically trigger the touch event in android?

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);
