Android自动化测试中实现长按并拖动
2018-07-20 来源:open-open
android应用自动化过程中,会遇见需要长按并拖动的场景,例如类似UC浏览器中,长按某个导航中的图标,使其处于可移动状态,然后再将其移动到另一 个地方,与其它导航图标换个位置,在robotium中有个drag(float fromX, float toX, float fromY, float toY,int stepCount)方法,但由于drag没有长按这个步骤,因此不能使应用处于可移动的状态,是没法完成这样的常见而简单的操作的。
drag方法源码实现如下:
public void drag(float fromX, float toX, float fromY, float toY, int stepCount) { long downTime = SystemClock.uptimeMillis(); long eventTime = SystemClock.uptimeMillis(); float y = fromY; float x = fromX; float yStep = (toY - fromY) / stepCount; float xStep = (toX - fromX) / stepCount; MotionEvent event = MotionEvent.obtain(downTime, eventTime,MotionEvent.ACTION_DOWN, fromX, fromY, 0); try { inst.sendPointerSync(event); } catch (SecurityException ignored) {} for (int i = 0; i < stepCount; ++i) { y += yStep; x += xStep; eventTime = SystemClock.uptimeMillis(); event = MotionEvent.obtain(downTime, eventTime,MotionEvent.ACTION_MOVE, x, y, 0); try { inst.sendPointerSync(event); } catch (SecurityException ignored) {} } eventTime = SystemClock.uptimeMillis(); event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP,toX, toY, 0); try { inst.sendPointerSync(event); } catch (SecurityException ignored) {} }
可以看出其实是通过MotionEvent的ACTION_DOWN模拟屏幕按下操 作,ACTION_MOVE模拟手势在屏幕上滑动,ACTION_UP模拟手势离开屏幕,从而完成整个拖动过程,而且其实robotium中的各种点击类 方法也都是通过模拟不同的手势完成的。
因此要想完成长按并拖动的操作,只要在ACTION_DOWN之后,停留一段时间即可模拟长按操作。
/** * 实现将一个视图拖动到另一个视图所在的位置 * @param viewFrom 起始View * @param viewTo 终点View * @throws Exception */ public void clickLongAndDrag(View viewFrom,View viewTo) throws Exception { //获得视图View中手机屏幕上的绝对x、y坐标 final int[] location = new int[2]; final int[] location2 = new int[2]; viewFrom.getLocationOnScreen(location); viewTo.getLocationOnScreen(location2); float xStart=location[0]; float yStart=location[1]; float xStop=location2[0]; float yStop=location2[1]; Log.i(TAG, "xStart:"+String.valueOf(xStart)); Log.i(TAG, "yStart:"+String.valueOf(yStart)); Log.i(TAG, "xStop:"+String.valueOf(xStop)); Log.i(TAG, "yStop:"+String.valueOf(yStop)); long downTime = SystemClock.uptimeMillis(); long eventTime = SystemClock.uptimeMillis(); try{ MotionEvent event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_DOWN, xStart+10f, yStart+10f, 0); inst.sendPointerSync(event); //event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, xStart+10f+1.0f, yStart+10f+1.0f, 0); //inst.sendPointerSync(event); //Thread.sleep(1000); //延迟一秒,模拟长按操作 eventTime = SystemClock.uptimeMillis() + 1000; //xStop加了10点坐标,获得的View坐标需根据应用实际情况稍做一点调整 event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, xStop+10f, yStop+50f, 0); inst.sendPointerSync(event); eventTime = SystemClock.uptimeMillis() + 1000; //又再小小移动了一次,不这么做的话可以无法激活被测应用状态,导致View移动后又回复到原来位置 event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, xStop+10f, yStop+10f, 0); inst.sendPointerSync(event); eventTime = SystemClock.uptimeMillis() + 1000; event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP, xStop+10f, yStop+10f, 0); inst.sendPointerSync(event); }catch (Exception ignored) { // Handle exceptions if necessary } }
