scrcpy学习--多点触控事件的模拟_scrcpy 模拟点击

 

input tap x y 命令可以进行模拟点击，但是只是一个点的事件，怎么进行多点模拟操作呢？

其实在MotionEvent里面把多点信息写进去就可以了。

 

我们可以参考scrcpy里面的写法，

https://github.com/Genymobile/scrcpy

 

    private boolean injectTouch(int action, long pointerId, Position position, float pressure, int buttons) {

        long now = SystemClock.uptimeMillis();

 

        Point point = device.getPhysicalPoint(position);

        if (point == null) {

            // ignore event

            return false;

        }

 

        int pointerIndex = pointersState.getPointerIndex(pointerId);

        if (pointerIndex == -1) {

            Ln.w("Too many pointers for touch event");

            return false;

        }

// pointersState里对pointer进行添加等管理

        Pointer pointer = pointersState.get(pointerIndex);

        pointer.setPoint(point);

        pointer.setPressure(pressure);

        pointer.setUp(action == MotionEvent.ACTION_UP);

//这里设置pointerProperties, pointerCoords

        int pointerCount = pointersState.update(pointerProperties, pointerCoords);

 

        if (pointerCount == 1) {

            if (action == MotionEvent.ACTION_DOWN) {

                lastTouchDown = now;

            }

        } else {

//设置多点事件的action，如105,105,205

            // secondary pointers must use ACTION_POINTER_* ORed with the pointerIndex

            if (action == MotionEvent.ACTION_UP) {

                action = MotionEvent.ACTION_POINTER_UP | (pointerIndex << MotionEvent.ACTION_POINTER_INDEX_SHIFT);

            } else if (action == MotionEvent.ACTION_DOWN) {

                action = MotionEvent.ACTION_POINTER_DOWN | (pointerIndex << MotionEvent.ACTION_POINTER_INDEX_SHIFT);

            }

        }

 

        MotionEvent event = MotionEvent

                .obtain(lastTouchDown, now, action, pointerCount, pointerProperties, pointerCoords, 0, buttons, 1f, 1f, DEVICE_ID_VIRTUAL, 0,

                        InputDevice.SOURCE_TOUCHSCREEN, 0);

        return device.injectEvent(event);

}

 

 

调用injectInputEvent方法

 

    public boolean injectEvent(InputEvent event) {

        return injectEvent(event, InputManager.INJECT_INPUT_EVENT_MODE_ASYNC);

    }

 

    public boolean injectEvent(InputEvent inputEvent, int mode) {

        if (!supportsInputEvents()) {

            throw new AssertionError("Could not inject input event if !supportsInputEvents()");

        }

 

        if (displayId != 0 && !InputManager.setDisplayId(inputEvent, displayId)) {

            return false;

        }

 

        return serviceManager.getInputManager().injectInputEvent(inputEvent, mode);

    }

 

 

设置好几个点的轨迹，组装好MotionEvent, 就可以使用injectInputEvent来注入多点触控事件了。MotionEvent的getActionIndex方法可以获取到当前的操作的事件是哪个点发起的。
