问题描述

我有类似这个问题的问题: PreferenceActivity中的自定义标题栏?

I have the same problem like this question: Custom title bar in PreferenceActivity?

扩展PreferenceActivity之后,我在onCreate()中编写此代码,它只是显示一个空白的灰色标题.我认为这是一个错误(因为此解决方案适用于Activity).

After extending PreferenceActivity, I write this code in onCreate(), it just shows a blank grey title. I think it is a bug (because this solution works well with Activity).

requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.main_pref);
