到目前为止，我从 ActionBarSherlock 迁移到 ActionBarCompat 没有更大的问题。在我的 Nexus 4 上，它运行良好。当我开始在运行 2.3.6 的旧 Nexus One 上进行测试时，我在旋转设备时遇到了问题。我请求一个 Window 功能来显示 ActionBar 中的中间进度：

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

    requestWindowFeature(android.view.Window.FEATURE_PROGRESS);
    requestWindowFeature(android.view.Window.FEATURE_INDETERMINATE_PROGRESS);

    setupActionBar(getSupportActionBar());

}

这在果冻豆上效果很好。

在 2.3.6 上获取此堆栈跟踪：

打电话supportRequestWindowFeature(Window.FEATURE_...)。

请参阅http://android-developers.blogspot.com/2013/08/actionbarcompat-and-io-2013-app-source.html

利用supportRequestWindowFeature(WindowCompat.FEATURE_xxx)

即您还需要使用WindowCompat.FEATURE_xxx而不是Window.FEATURE_xxx向后兼容。

对于那些不调用requestWindowFeature()方法但仍然遇到异常的人，请尝试以下解决方法：

@Override
protected void onCreate(Bundle savedInstanceState) {
    try {
        super.onCreate(savedInstanceState);
    } catch (Throwable e) {
        //dummy workaround
    }
    setContentView(getLayoutResId());

错误日志清楚地表明“必须在添加内容之前调用 requestFeature()”。所以你必须调用'super.onCreate(savedInstanceState);' 在“requestWindowFeature”调用之后。并且不需要如上所述调用 supportRequestWindowFeature(Window.FEATURE_...) 。请参阅下面的工作代码。

  @Override
    public void onCreate(Bundle savedInstanceState) {
        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
        requestWindowFeature(Window.FEATURE_PROGRESS);
        super.onCreate(savedInstanceState);
