Android 7.0 Settings 根目录添加自定义功能项

一.添加自定义分组

1.Settings/res/values/donottranslate.xml 添加自定义分组类型

<string name="category_key_olcsettings">com.android.settings.category.olcsettings</string>

添加自定义分组类型

2.添加自定义类型的实现

Settings/src/com/android/settings/Settings.java 添加分组类型实现

public class Settings extends SettingsActivity {

......

public static class OlcSettings extends SettingsActivity { /* empty */ }

......

}

3.在 AndroidManifest.xml 中声明自定义类型分组类型

......

<activity android:name=".Settings$OlcSettings"

android:label="@string/header_category_olc_settings">

<intent-filter android:priority="5"> <!-- priority="5" 数字越大越靠前-->

<!-- 第一步声明的自定义分组类型名称-->

<action android:name="com.android.settings.category.olcsettings" />

<category android:name="android.intent.category.DEFAULT" />

</intent-filter>

</activity>

二. 在自定义分组类型下添加功能项

1.创建自定义功能

package com.olc.net;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import com.android.internal.logging.MetricsProto.MetricsEvent;

import com.android.settings.SettingsPreferenceFragment;

import com.android.settings.R;

public class LANNTPServerVerify extends SettingsPreferenceFragment {

/** 继承父类SettingsPreferenceFragment 必须实现的方法, MetricsEvent.OLC_SETTINGS需要添加定义*/

@Override

protected int getMetricsCategory() {

return MetricsEvent.OLC_SETTINGS;

}

@Override

public void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

}

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

// TODO Auto-generated method stub

final View view = inflater.inflate(R.layout.olc_security_verify_pwd,

container, false);

return view;

}

}

2. 添加 MetricsEvent.OLC_SETTINGS 的定义

framework/base/proto/src/metrics_constants.proto 应避免数值重复

......

//wpx olc settings

// OPEN: Settings > settings

// CATEGORY: SETTINGS

// OS: 6.0

OLC_SETTINGS = 744;

......

3.添加自定义功能

Settings/src/com/android/settings/Settings.java

......

public static class LANNTPServerVerifyActivity extends SettingsActivity { /* empty */ }

......

4.修改SettingsActivity

Settings/src/com/android/settings/SettingsActivity.java

// Show only these settings for restricted users

private String[] SETTINGS_FOR_RESTRICTED = {

......

Settings.LANNTPServerVerifyActivity.class.getName(),

......

}

private static final String[] ENTRY_FRAGMENTS = {

......

com.olc.net.LANNTPServerVerify.class.getName(),

......

}

5.修改 AndroidManifest.xml

添加

<activity android:name="Settings$LANNTPServerVerifyActivity"

android:label="@string/olc_settings_lan_time_sync"

android:icon="@drawable/ic_lan_ntp"

android:taskAffinity="">

<intent-filter android:priority="1">

<action android:name="com.android.settings.OLCSETTINGS_LANNET" />

<action android:name="android.settings.DISPLAY_SETTINGS" />

<category android:name="android.intent.category.DEFAULT" />

</intent-filter>

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.DEFAULT" />

<category android:name="android.intent.category.VOICE_LAUNCH" />

<category android:name="com.android.settings.SHORTCUT" />

</intent-filter>

<intent-filter android:priority="9">

<action android:name="com.android.settings.action.SETTINGS" />

</intent-filter>

<!-- 定义此功能项,归属那个分类. com.android.settings.category.olcsettings 是Settings/res/values/donottranslate.xml 自定义的分组名称-->

<meta-data android:name="com.android.settings.category"

android:value="com.android.settings.category.olcsettings" />

<!-- 指定自定义 Frame 路径 "com.olc.security.OlcSecurityVerify"

<meta-data android:name="com.android.settings.FRAGMENT_CLASS"

android:value="com.olc.security.OlcSecurityVerify" />

<meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED"

android:value="true" />

</activity>
