弹出滑动菜单时，轻轻移动操作栏中的主页图标

Question

我正在阅读有关滑动菜单/导航菜单的google's official doc。

我无法实现的一件事就是轻轻移动操作栏上的主页图标。请参阅以下屏幕截图 - 弹出滑动菜单时，图标会稍微向左移动。怎么做？

Answer 1

在创建drawable时定义ActionBarDrawerToggle后，请确保将以下内容添加到Activity以便进行滑动效果：

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);

    mDrawerToggle.syncState();
}

Answer 2

使用https://developer.android.com/reference/android/support/v4/app/ActionBarDrawerToggle.html

您将drawable提供给ActionBarToggle实例，它会为您处理它。

new ActionBarDrawerToggle(this, mDrawerLayout,
                    R.drawable.ic_drawer, R.string.drawer_open,
                    R.string.drawer_close);

它需要一个用于打开和关闭的字符串，一个图标的图像以及附加到它的DrawerLayout。

这是我在我的一个应用程序中扩展我所有活动的课程。它确保抽屉在我的所有活动中都能正常工作。
