Android ActionBarDrawerToggle onDrawerClosed 延迟后调用

Question

我有一个应用程序，我在其中覆盖 onDrawerClosed 的 ActionBarDrawerToggle。我注意到在调用onDrawerClosed 方法之前总是存在不必要的延迟。这个问题很容易发现：当我覆盖onDrawerSlide 并输入一些日志记录时，我清楚地看到在调用onDrawerClosed 之前的50-100ms 之间的slideOffset 值是0.0。为什么会出现延迟？

mDrawerToggle = new ActionBarDrawerToggle([...]) {
    public void onDrawerClosed(View view) {
        Log.d(TAG, String.format("% 12d onDrawerClosed", Calendar.getInstance().getTimeInMillis()));
        super.onDrawerClosed(view);
    }

    public void onDrawerOpened(View drawerView) {
        super.onDrawerOpened(drawerView);
    }

    @Override
    public void onDrawerSlide(View drawerView, float slideOffset) {
        Log.d(TAG, String.format("% 12d onDrawerSlide %f", Calendar.getInstance().getTimeInMillis(), slideOffset)));
        // THIS IS CALLED WITH slideOffset = 0.0f TOO LONG BEFORE onDrawerClosed
        super.onDrawerSlide(drawerView, slideOffset);
    }
};

我不确定这个答案，你能不能在超级调用之后把那个 Log.d 放出来
