摘要：在使用自動(dòng)化測試框架過程中，基于對(duì)控件實(shí)現(xiàn)長按，發(fā)現(xiàn)自帶的方法很多時(shí)候不能實(shí)現(xiàn)對(duì)控件的長按，因此需要重寫該方法。主要代碼如下調(diào)用方式在使用自動(dòng)化框架時(shí)，調(diào)用方法來實(shí)現(xiàn)對(duì)控件長按效果。其中參數(shù)控件對(duì)象，表示長按時(shí)間，單位為毫秒。

在使用uiautomator自動(dòng)化測試框架過程中，基于對(duì)控件實(shí)現(xiàn)長按，發(fā)現(xiàn)uiautomator自帶的方法longClick()很多時(shí)候不能實(shí)現(xiàn)對(duì)控件的長按，因此需要重寫該方法。

主要代碼如下：

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;
}

調(diào)用方式：
在使用uiautomator自動(dòng)化框架時(shí)，調(diào)用longClickWithTime(Object, time)方法來實(shí)現(xiàn)對(duì)UiObject控件長按效果。其中Object參數(shù)：uiautomator UiObject控件對(duì)象，time：表示長按時(shí)間，單位為毫秒。
例如：對(duì)手機(jī)主頁時(shí)鐘按鈕進(jìn)行長按5s操作，
longClickWithTime(new UiCollection(new UiObject(new UiSelector().text("Clock")), 5000)；
