问题描述

我必须写一个preferenceActivity，它包含嵌套子preferenceScreen。问题是我想要让他们全屏，我在AndroidManifest添加theme.fullscreen和它的作品，但是当我在分项之一点击进入一个嵌套的preferenceScreen，出现在标题栏。现在我不知道如何让嵌套全屏了。
我已经看源$ C ​​$ C为preferenceScreen寻求帮助。它表明嵌套preferenceScreen被显示在一个对话框，而且我发现code哪些新的对话框中方法的ShowDialog。

I have write an PreferenceActivity and it contains nested child PreferenceScreen. the problem is i want made them FullScreen, i've add theme.fullscreen in AndroidManifest and it works, but when i click on one of the sub-item to enter an nested PreferenceScreen, the title bar appears. and now i didn't know how to make the nested full screen too. and i've look source code for PreferenceScreen to find help. it shows that nested preferenceScreen was showed on an Dialog, and i found the code which new the Dialog in method showDialog.

Dialog dialog = mDialog = new Dialog(context, TextUtils.isEmpty(title)
            ? com.android.internal.R.style.Theme_NoTitleBar
            : com.android.internal.R.style.Theme);

似乎noway要做到这一点，但我真的想知道的是任何人都可以在一个preferenceActivity实现这一点。

it seems that noway to do that, but i really want to know is anyone can implement this in one PreferenceActivity.
