Android自动化测试中实现长按并拖动，android自动化,android应用自动化

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(floatfromX,floattoX,floatfromY,floattoY,intstepCount)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。
