在使用uiautomator自动化测试框架过程中,基于对控件实现长按,发现uiautomator自带的方法longClick()很多时候不能实现对控件的长按,因此需要重写该方法。
  主要代码如下:
public static boolean longClickWithTime(UiObject obj, long time) throws Exception {
Class<?> InteractionControllerClass = null;
Method findAccessibilityNodeInfoMethod = null;
Method getInteractionControllerMethod = null;
Method touchDownMethod = null;
Method touchUpMethod = null;
Field WAIT_FOR_SELECTOR_TIMEOUT = null;
findAccessibilityNodeInfoMethod = UiObject.class.getDeclaredMethod("findAccessibilityNodeInfo",long.class);
findAccessibilityNodeInfoMethod.setAccessible(true);
WAIT_FOR_SELECTOR_TIMEOUT = UiObject.class.getDeclaredField("WAIT_FOR_SELECTOR_TIMEOUT");
WAIT_FOR_SELECTOR_TIMEOUT.setAccessible(true);
AccessibilityNodeInfo node = (AccessibilityNodeInfo) findAccessibilityNodeInfoMethod.invoke(obj, WAIT_FOR_SELECTOR_TIMEOUT.getLong(obj));
if(node == null) {
throw new UiObjectNotFoundException(obj.getSelector().toString());
}
Rect rect = obj.getVisibleBounds();
getInteractionControllerMethod = UiObject.class.getDeclaredMethod("getInteractionController");
getInteractionControllerMethod.setAccessible(true);
Object interactionController = getInteractionControllerMethod.invoke(obj);
InteractionControllerClass = Class.forName("com.android.uiautomator.core.InteractionController");
touchDownMethod = InteractionControllerClass.getDeclaredMethod("touchDown", int.class, int.class);
touchDownMethod.setAccessible(true);
touchUpMethod = InteractionControllerClass.getDeclaredMethod("touchUp", int.class, int.class);
touchUpMethod.setAccessible(true);
if(Boolean.parseBoolean(touchDownMethod.invoke(interactionController, rect.centerX(), rect.centerY()).toString())) {
SystemClock.sleep(time);
if(Boolean.parseBoolean(touchUpMethod.invoke(interactionController, rect.centerX(), rect.centerY()).toString())) {
return true;
}
}
return false;
}
  调用方式:
  在使用uiautomator自动化框架时,调用longClickWithTime(Object, time)方法来实现对UiObject控件长按效果。其中Object参数:uiautomator UiObject控件对象,time:表示长按时间,单位为毫秒。
  例如:对手机主页时钟按钮进行长按5s操作,
  longClickWithTime(new UiCollection(new UiObject(new UiSelector().text("Clock")), 5000);
