模拟MotionEvent事件

这两天在做模块的单元测试，需要模拟触屏事件，手势操作，下面针对MotionEvent做下代码记录：

下面的事件注入都会调用一个函数：

Instrumentation mInstrumentation;public void sendPointerEvent(int action, Point point) {MotionEvent event = MotionEvent.obtain(SystemClock.uptimeMillis(),SystemClock.uptimeMillis(), action, point.x, point.y, 0);mInstrumentation.sendPointerSync(event);event.recycle();}

1，MotionEvent.ACTION_DOWN

Down跟UP通常是连着的。

Point selectPoint = new Point(670,470);
sendPointerEvent(MotionEvent.ACTION_DOWN, selectPoint);
sendPointerEvent(MotionEvent.ACTION_UP, selectPoint);

2，MotionEvent.ACTION_MOVE

从一个Down事件开始，中间loop多个Move，最后一个Up事件。

Point from = new Point(150, 650);
Point to = new Point(150, 260);
sendPointerEvent(MotionEvent.ACTION_DOWN, from);
MovePointerEvent(from, to, 10, 10);
sendPointerEvent(MotionEvent.ACTION_UP, to);

这里计算move的步进：

    private int getNextMoveValue(int oldValue, int targetValue, int distance, int step) {if (targetValue - oldValue > distance) {return oldValue + step;} else if (targetValue - oldValue < -distance) {return oldValue - step;} else {return targetValue;}}

3，手势操作，缩放

private int PINCH_STEP_COUNT = 10;public void scaleGestureDetector() {try {final float initialScaleFactor = 1.0f;final DisplayMetrics dm = new DisplayMetrics();final WindowManager wm =(WindowManager)mContext.getSystemService(Context.WINDOW_SERVICE);//obtain the display size ,so that to get start and end coordinates.wm.getDefaultDisplay().getMetrics(dm);final int displayWidth = dm.widthPixels;final int displayHeight = dm.heightPixels;//from center,pinch to 75% of display.final int centerX = displayWidth / 2;final int centerY = displayHeight / 2;final float[] firstFingerStartCoords = new float[] {centerX + 1.0f, centerY - 1.0f};final float[] firstFingerEndCoords =new float[] {0.75f * displayWidth, 0.25f * displayHeight};//the second point different from the first.final float[] secondFingerStartCoords = new float[] {centerX - 1.0f, centerY + 1.0f};final float[] secondFingerEndCoords =new float[] {0.25f * displayWidth, 0.75f * displayHeight};//specify the touch properites.final MotionEvent.PointerProperties pp1 = new MotionEvent.PointerProperties();pp1.id = 0;pp1.toolType = MotionEvent.TOOL_TYPE_FINGER;final MotionEvent.PointerProperties pp2 = new MotionEvent.PointerProperties();pp2.id = 1;pp2.toolType = MotionEvent.TOOL_TYPE_FINGER;MotionEvent.PointerProperties[] pointerProperties =new MotionEvent.PointerProperties[]{pp1, pp2};//specify the motion properites.final MotionEvent.PointerCoords pc1 = new MotionEvent.PointerCoords();pc1.x = firstFingerStartCoords[0];pc1.y = firstFingerStartCoords[1];pc1.pressure = 1;pc1.size = 1;final MotionEvent.PointerCoords pc2 = new MotionEvent.PointerCoords();pc2.x = secondFingerStartCoords[0];pc2.y = secondFingerEndCoords[1];pc2.pressure = 1;pc2.size = 1;final long startTime = SystemClock.uptimeMillis();long eventTime = startTime;final MotionEvent.PointerCoords[] pointerCoords = new MotionEvent.PointerCoords[]{pc1, pc2};final MotionEvent firstFingerEvent = MotionEvent.obtain(startTime,eventTime, MotionEvent.ACTION_DOWN, 1, pointerProperties, pointerCoords,0, 0, 1, 1, 0, 0, 0, 0);eventTime = SystemClock.uptimeMillis();final MotionEvent secondFingerEvent = MotionEvent.obtain(startTime, eventTime,MotionEvent.ACTION_POINTER_DOWN +(pp2.id << MotionEvent.ACTION_POINTER_INDEX_SHIFT),2, pointerProperties, pointerCoords, 0, 0, 1, 1, 0, 0, 0, 0);//inject the start down event.mInstrumentation.sendPointerSync(firstFingerEvent);mInstrumentation.sendPointerSync(secondFingerEvent);final float[][] stepsFirstFinger = interpolate(firstFingerStartCoords,firstFingerEndCoords);final float[][] stepsSecondFinger = interpolate(secondFingerStartCoords,secondFingerEndCoords);//loop the motion of two fingers to the end points.for (int i = 0; i < PINCH_STEP_COUNT; i++) {eventTime = SystemClock.uptimeMillis();pc1.x = stepsFirstFinger[i][0];pc1.y = stepsFirstFinger[i][1];pc2.x = stepsSecondFinger[i][0];pc2.y = stepsSecondFinger[i][1];final MotionEvent event = MotionEvent.obtain(startTime, eventTime,MotionEvent.ACTION_MOVE, 2, pointerProperties, pointerCoords,0, 0, 1, 1, 0, 0, 0, 0);mInstrumentation.sendPointerSync(event);Thread.sleep(TIMEWAITING*4/5);}eventTime = SystemClock.uptimeMillis();final MotionEvent secondFingerUpEvent = MotionEvent.obtain(startTime, eventTime,MotionEvent.ACTION_POINTER_UP, 2, pointerProperties, pointerCoords,0, 0, 1, 1, 0, 0, 0, 0);//inject the up event.mInstrumentation.sendPointerSync(secondFingerUpEvent);eventTime = SystemClock.uptimeMillis();final MotionEvent firstFingerUpEvent = MotionEvent.obtain(startTime, eventTime,MotionEvent.ACTION_POINTER_UP, 1, pointerProperties, pointerCoords,0, 0, 1, 1, 0, 0, 0, 0);mInstrumentation.sendPointerSync(firstFingerUpEvent);}catch (InterruptedException e) {e.printStackTrace();Thread.currentThread().interrupt();}}

两个手指移动的差值计算：

    private float[][] interpolate(float[] start, float[] end) {float[][] res = new float[PINCH_STEP_COUNT][2];for (int i = 0; i < PINCH_STEP_COUNT; i++) {res[i][0] = start[0] + (end[0] - start[0]) * i / (PINCH_STEP_COUNT - 1f);res[i][1] = start[1] + (end[1] - start[1]) * i / (PINCH_STEP_COUNT - 1f);}return res;}
