android自動化測試中實現長按並拖動

   android應用自動化過程中,會遇見需要長按並拖動的場景,例如類似UC浏覽器中,長按某個導航中的圖標,使其處於可移動狀態,然後再將其移動到另一個地方,與其它導航圖標換個位置,在robotium中有個drag(float fromX, float toX, float fromY, float toY,int stepCount)方法,但由於drag沒有長按這個步驟,因此不能使應用處於可移動的狀態,是沒法完成這樣的常見而簡單的操作的。

  drag方法源碼實現如下:

  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) {}

  }

  可以看出其實是通過MotionEvent的ACTION_DOWN模擬屏幕按下操作,ACTION_MOVE模擬手勢在屏幕上滑動,ACTION_UP模擬手勢離開屏幕,從而完成整個拖動過程,而且其實robotium中的各種點擊類方法也都是通過模擬不同的手勢完成的。

  因此要想完成長按並拖動的操作,只要在ACTION_DOWN之後,停留一段時間即可模擬長按操作。

  /**

  * @param viewFrom 起始View

  * @param viewTo 終點View

  * @throws Exception

  */

  public void clickLongAndDrag(View viewFrom,View viewTo) throws Exception {

  //獲得視圖View中手機屏幕上的絕對x、y坐標

  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);

  //延遲一秒,模擬長按操作

  eventTime = SystemClock.uptimeMillis() + 1000;

  //xStop加了10點坐標,獲得的View坐標需根據應用實際情況稍做一點調整

  event = MotionEvent.obtain(downTime, eventTime, MotionEvent.ACTION_MOVE, xStop+10f, yStop+50f, 0);

  inst.sendPointerSync(event);

  eventTime = SystemClock.uptimeMillis() + 1000;

  //又再小小移動了一次,不這麼做的話可以無法激活被測應用狀態,導致View移動後又回復到原來位置

  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

  }

  }
