如何从preferenceCategory标题栏preferenceActivity [英] How to remove the title bar from PreferenceCategory in PreferenceActivity

问题描述

这是我的preferences XML文件：我的preferences.xml：

This is my preferences xml file: myPreferences.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory>
    <EditTextPreference android:key="name" android:title="Name" android:inputType="text" android:defaultValue="" />
    <EditTextPreference android:key="email" android:title="Email" android:inputType="textEmailAddress" android:defaultValue="" />
    <EditTextPreference android:key="phone" android:title="Phone Number" android:inputType="phone" android:defaultValue="" />
    <EditTextPreference android:key="zipcode" android:title="Zip Code" android:inputType="number" android:defaultValue="" />
</PreferenceCategory>
</PreferenceScreen>

这是我的preferences活动的声明，我的Andr​​oidManifest.xml：

This is my preferences activity declaration in my AndroidManifest.xml:

<activity
        android:name=".activities.MyPreferencesActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" />

和，这是我尝试过运用到我的活动方式：

And, this is a style I have tried applying to my activity before:

 <activity
     android:name=".activities.MyPreferencesActivity"
     android:screenOrientation="portrait"
     android:theme="@android:style/PreferenceTheme" />

 <style name="PreferenceTheme">
     <item name="android:background">@drawable/background_preferences</item>
     <item name="android:windowNoTitle">true</item>
 </style>

这是行不通的。

然后，我试着做它通过Java code在我的我的preferencesActivity的的onCreate：

Then, I've tried doing it through java code in my onCreate of myPreferencesActivity:

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     requestWindowFeature(Window.FEATURE_NO_TITLE);
     super.onCreate(savedInstanceState);
 addPreferencesFromResource(R.xml.myPreferences);
 }

不工作。试图标题设置为绘制。

Doesn't work. Tried setting the title to a drawable.

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
     super.onCreate(savedInstanceState);
     addPreferencesFromResource(R.xml.preferences_profile);
     getWindow().setFeatureDrawableResource(Window.FEATURE_CUSTOM_TITLE, R.drawable.profile_banner);
 }

不。不工作。

一切我只是做删除preference活动的标题栏，但不是preference类别。

Everything I did only removes the title bar of the preference activity but not the preference category.

有人能帮帮我吗？先谢谢了。

Could someone please help me? Thanks in advance.

推荐答案

如果你不希望有上述一组preferences的标题栏，不使用 preferenceCategory ，因为它是服务没有目的，只是把你所有的preferences到 preferenceScreen 元素：

If you don't want to have a title bar above a group of preferences, don't use a PreferenceCategory as it is serving no purpose, and just put all your preferences into the PreferenceScreen element:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">

    <EditTextPreference android:key="name" android:title="Name" android:inputType="text" android:defaultValue="" />
    <EditTextPreference android:key="email" android:title="Email" android:inputType="textEmailAddress" android:defaultValue="" />
    <EditTextPreference android:key="phone" android:title="Phone Number" android:inputType="phone" android:defaultValue="" />
    <EditTextPreference android:key="zipcode" android:title="Zip Code" android:inputType="number" android:defaultValue="" />

</PreferenceScreen>
