Use programming to set touch input on android

问题

I want to use programming to mimic a "touch" on a position (x, y) on the screen.

I saw this link, but it only teaches you how to inject characters.

I want to inject a touch at position (x, y)

How do I do this using Android SDK (which is java)?

回答1:

You can "fake" a touch event like this:

MotionEvent event = MotionEvent.obtain(downTime, eventTime, action, x, y, metaState);
view.onTouchEvent(event);

API Docs:

Create a new MotionEvent, filling in a subset of the basic motion values. Those not specified here are: device id (always 0), pressure and size (always 1), x and y precision (always 1), and edgeFlags (always 0).

Parameters:

downTime The time (in ms) when the user originally pressed down to start a stream of position events. This must be obtained from SystemClock.uptimeMillis().
eventTime The the time (in ms) when this specific event was generated. This must be obtained from SystemClock.uptimeMillis().
action The kind of action being performed -- one of either ACTION_DOWN, ACTION_MOVE, ACTION_UP, or ACTION_CANCEL.
x The X coordinate of this event.
y The Y coordinate of this event.
metaState The state of any meta / modifier keys that were in effect when the event was generated.
