推荐答案

您看到的应用程序图标的任何触摸的反馈？ （是否发光，当你preSS吗？）

Are you seeing any touch feedback from the app icon? (Does it glow when you press it?)

由于许多活动，不使用操作栏home键，在应用程序，针对API 14+在Android 4.0上运行它默认是禁用的。 （这是为了让用户不要试图pressing它，看到它焕发，但不知道为什么什么都没有发生。）希望利用这个应该叫<一个应用程序href="http://developer.android.com/reference/android/app/ActionBar.html#setHomeButtonEnabled%28boolean%29"><$c$c>ActionBar#setHomeButtonEnabled(true).

Since many activities do not use the action bar home button, in apps that target API 14+ running on Android 4.0 it is disabled by default. (This is so that users don't try pressing it, see it glow, and wonder why nothing happened.) Apps that want to use this should call ActionBar#setHomeButtonEnabled(true).

我们也许应该修改ActionBarCompat样本更清晰地浮出水面这一点。一个简单的办法让你和运行将修改ActionBarHelperICS.java并添加以下内容：

We should probably revise the ActionBarCompat sample to surface this more clearly. One simple way to get you up and running would be to modify ActionBarHelperICS.java and add the following:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mActivity.getActionBar().setHomeButtonEnabled(true);
}

在你想要更多地控制开启和关闭，你把这个将要作进一步修改的应用程序。

In an app where you want more control over turning this on and off you would want to make further changes.
