Question

我正在为自动化制作SKD。所以我的需求与正常的应用程序开发略有不同。

要求：获取当前活动的ViewHierarchy。问题：当Spinner未打开时，我认为它是正确的。旋转器开启时我没有得到微调器的细节。

我使用以下代码来获取层次结构。问题是：Spinner是否在不同的窗口中托管，这就是为什么我没有得到它？得到它的方法是什么？

    //This is how I start recursion to get view hierarchy
    View view = getWindow().getDecorView().getRootView();
    if (view instanceof ViewGroup) {
        ViewGroup group = (ViewGroup) view;
        dumpViewHierarchyWithProperties( group, 0);
    }

//Functions to get hierarchy
private  void dumpViewHierarchyWithProperties(ViewGroup group,int level) {
    if (!dumpViewWithProperties(group, level)) {
        return;
    }

    final int count = group.getChildCount();
    for (int i = 0; i < count; i++) {
        final View view = group.getChildAt(i);
        if (view instanceof ViewGroup) {
            dumpViewHierarchyWithProperties((ViewGroup) view, level + 1);
        } else {
            dumpViewWithProperties(view, level + 1);
        }
    }
}

private  boolean dumpViewWithProperties(View view,int level) {

    //Add to view Hierarchy.
    return true;
}

我设法使用部分代码获取打开的微调器弹出视图层次结构以及其他一些反射魔法，这里是完整代码，请记住反射会影响SDK和使用的应用程序的性能它

//Function to get all available windows of the application using reflection
private void logRootViews() {
    try {
        Class wmgClass = Class.forName("android.view.WindowManagerGlobal");
        Object wmgInstnace = wmgClass.getMethod("getInstance").invoke(null, (Object[])null);

        Method getViewRootNames = wmgClass.getMethod("getViewRootNames");
        Method getRootView = wmgClass.getMethod("getRootView", String.class);
        String[] rootViewNames = (String[])getViewRootNames.invoke(wmgInstnace, (Object[])null);

        for(String viewName : rootViewNames) {
            View rootView = (View)getRootView.invoke(wmgInstnace, viewName);
            Log.i(TAG, "Found root view: " + viewName + ": " + rootView);
            getViewHierarchy(rootView);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

//Functions to get hierarchy
private void getViewHierarchy(View view) {
    //This is how I start recursion to get view hierarchy
    if (view instanceof ViewGroup) {
        ViewGroup group = (ViewGroup) view;
        dumpViewHierarchyWithProperties(group, 0);
    } else {
        dumpViewWithProperties(view, 0);
    }
}

private void dumpViewHierarchyWithProperties(ViewGroup group, int level) {
    if (!dumpViewWithProperties(group, level)) {
        return;
    }

    final int count = group.getChildCount();
    for (int i = 0; i < count; i++) {
        final View view = group.getChildAt(i);
        if (view instanceof ViewGroup) {
            dumpViewHierarchyWithProperties((ViewGroup) view, level + 1);
        } else {
            dumpViewWithProperties(view, level + 1);
        }
    }
}

private boolean dumpViewWithProperties(View view, int level) {
    //Add to view Hierarchy.
    if (view instanceof TextView) {
        Log.d(TAG, "TextView from hierarchy dumped: " + view.toString() + " with text: " + ((TextView) view).getText().toString() + " ,in Level: " + level);
    } else {
        Log.d(TAG, "View from hierarchy dumped: " + view.toString() + " ,in Level: " + level);
    }
    return true;
}
