拖放浓缩咖啡

Question

是否可以通过Espresso执行拖动&拖放操作？为了在我的自动化测试中接受一些条件，我需要向下移动一个视图（以直线形式）。

Answer 1

您可以使用GeneralSwipeAction来拖放&拖放。

public static ViewAction swipeUp() { 
return new GeneralSwipeAction(Swipe.FAST, GeneralLocation.BOTTOM_CENTER, 
    GeneralLocation.TOP_CENTER, Press.FINGER); 
} 

您也可以自定义位置以符合您的要求。

多数民众赞成我是如何做到这一点。您可以更多地访问您的视图应该发生的情况。但接受的答案也执行拖动&下降。

public static void drag(Instrumentation inst, 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, x, y, 0); 
     inst.sendPointerSync(event); 
     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); 
      inst.sendPointerSync(event); 
     } 

     eventTime = SystemClock.uptimeMillis(); 
     event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_UP, x, y, 0); 
     inst.sendPointerSync(event); 
     inst.waitForIdleSync(); 
    }
