- Android原生设置Settings 具体Fragment和Activity界面跳转实现
一、前言
Android 原生设置Settings中如果要跳转到某个界面，如何实现？
从代码上看，只能看到某些Activity的跳转，或者一些主要的Fragment是有暴露的，
而对于多层级的Fragment 没看到有代码有直接暴露的代码。
这种情况，如果要跳转到某个Fragment，要如何实现呢？
其实原生Settings 对这块需求是有设计实现功能的，可以实现跳转到某个未暴露的Fragment 界面，
但是有个限制：跳转未暴露的Fragment 应用需要是系统签名uid=1000d的应用，不然会报错。
对于跳转到具体Fragment和Activity的需求，在实际项目中还是比较实用的，毕竟原生Settings很多功能是其他应用没有实现的。
最初只想介绍一下Fragment跳转的，后面随便看了暴露的Activity界面，也简单写上去了。
如果有需求的可以继续往下看看，Android上层正常开发估计也有比较大作用的，有需求的可以收藏查看。
二、实现跳转到Settings某个界面的代码
1、跳转到某个Settings 应用和某个Fragment 界面示例
//跳转到Settings应用有N种方法，这是其中一个 public void jumpMain(View view) { Intent intent = new Intent(); intent.setAction("android.settings.SETTINGS"); intent.setPackage("com.android.settings"); startActivity(intent); } //跳转到开发组选项界面 public void jumpDeveloper(View view) { Intent intent = new Intent(); intent.setComponent(new ComponentName("com.android.settings", "com.android.settings.SubSettings")); intent.putExtra(":settings:show_fragment", "com.android.settings.development.DevelopmentSettingsDashboardFragment"); startActivity(intent); } 第二个方法就是跳转到Settings 某个Fragment界面的代码。
2、跳转到某个Settings某个Fragment 界面的封装方法代码
//跳转到开发这选项界面 public void jumpDeveloper(View view) { jumpSettingsFragment("development.DevelopmentSettingsDashboardFragment"); } //跳转到签名证书信息界面 public void jumpSecurity(View view) { jumpSettingsFragment("security.EncryptionAndCredential"); } //其他Settings里面的Fragment 也可以调用这个封装方法 //跳转到某个Fragment的封装方法，只要传入最后的包名和类名 public void jumpSettingsFragment(String fragmentName) { Intent intent = new Intent(); intent.setComponent(new ComponentName("com.android.settings", "com.android.settings.SubSettings")); intent.putExtra(":settings:show_fragment", "com.android.settings." + fragmentName); startActivity(intent); } 通过封装的方法，传入模块名称和相关Fragment名称就可以显示到具体的界面。
3、其他Fragment界面的信息：
Android 原生设置Settings各个功能模块的代码是分别写在不同的文件的。每个文件夹都是一个功能模块，里面包含一些工具类，Activity 和 Fragment 等界面。
（1）原生Settings外层目录图片：
截图展示不了那么多，上面只是src的部分目录，下面的是详细目录。
（2）Android14 原生Settings文件目录 列表：
release$ cd packages/apps/Settings/src/com/android/settings/ accessibility/ bluetooth/ deletionhelper/ ethernet/ location/ print/ shortcut/ theme/ wfd/ accounts/ bugreporthandler/ development/ flashlight/ media/ privacy/ sim/ tts/ widget/ activityembedding/ communal/ deviceinfo/ fuelgauge/ network/ ramextension/ slices/ users/ wifi/ applications/ connecteddevice/ devicelock/ gestures/ nfc/ regionalpreferences/ sound/ utils/ aware/ core/ display/ homepage/ notification/ safetycenter/ spa/ uwb/ backup/ dashboard/ dream/ inputmethod/ overlay/ screenshot/ support/ vpn2/ biometrics/ datausage/ emergency/ language/ panel/ search/ survey/ wallpaper/ biometrics2/ datetime/ enterprise/ localepicker/ password/ security/ system/ webview/ release$ cd packages/apps/Settings/src/com/android/settings/ 应该不是所有的Fragment都可以使用 “:settings:show_fragment” 方式展示，Settings中有些界面是单独的Activity和Fragment。
大部分Fragment界面都是可以使用 ":settings:show_fragment"方式进行跳转，
这些Fragment界面是没有归类的，需要大家在使用过程进行研究使用。
三、其他
1、adb命令 跳转到Settings应用：
//方式1： adb shell am start -a android.settings.SETTINGS //方式2： am start com.android.settings/.Settings //方式3： am start com.android.settings/.SubSettings 其他方式肯定还有的，这里不一一介绍了。
2、使用adb 命令跳转到Settings Fragment 界面无效？
（1）使用“am broadcast”发送广播的命令不行？
C:\Users\As11040>adb shell am broadcast -n com.android.settings/com.android.settings.SubSettings --es ":settings:show_fragment" "com.android.settings.development.DevelopmentSettingsDashboardFragment" Broadcasting: Intent { flg=0x400000 cmp=com.android.settings/.SubSettings (has extras) } Broadcast completed: result=0 C:\Users\As11040> 返回结果是0，发送广播是没人接收。
为啥不行，按道理发送广播就是命令： “am broadcast XXX”
（2）可以使用“am start”的命令
C:\Users\As11040>adb shell am start -n com.android.settings/com.android.settings.SubSettings --es ":settings:show_fragment" "com.android.settings.development.DevelopmentSettingsDashboardFragment" Starting: Intent { cmp=com.android.settings/.SubSettings (has extras) } C:\Users\As11040> （3）am broadcast 和 am start 简单区别
am broadcast 用于发送广播； am start 用于启动 Activity。 比如自己有监听广播的代码，使用 am broadcast发送广播自己是可以收到的。 拉起界面就要用am start 了。 发送相关数据的参数形式 am broadcast 和 am start 是一样的。 所以说这里拉起应用不是发送广播，必须使用 am start 。
3、跳转到Settings的Fragment权限报错
如果要应用没有权限调用拉起Fragment 界面是会报错的。
（1）报错日志：
普通应用如果执行跳转到某个Fragment 的代码报错如下：
Caused by: java.lang.SecurityException: Permission Denial: starting Intent { cmp=com.android.settings/.SubSettings (has extras) } from ProcessRecord{a3725bd 7723:com.demo.settingsview/u0a96} (pid=7723, uid=10096) not exported from uid 1000 at android.os.Parcel.createExceptionOrNull(Parcel.java:3057) at android.os.Parcel.createException(Parcel.java:3041) at android.os.Parcel.readException(Parcel.java:3024) at android.os.Parcel.readException(Parcel.java:2966) at android.app.IActivityTaskManager$Stub$Proxy.startActivity(IActivityTaskManager.java:2243) at android.app.Instrumentation.execStartActivity(Instrumentation.java:1873) at android.app.Activity.startActivityForResult(Activity.java:5758) at androidx.fragment.app.FragmentActivity.startActivityForResult(FragmentActivity.java:676) at android.app.Activity.startActivityForResult(Activity.java:5716) at androidx.fragment.app.FragmentActivity.startActivityForResult(FragmentActivity.java:663) at android.app.Activity.startActivity(Activity.java:6214) at android.app.Activity.startActivity(Activity.java:6181) at com.demo.settingsview.MainActivity.jumpSettingsFragment(MainActivity.java:54) at com.demo.settingsview.MainActivity.jumpDeveloper(MainActivity.java:32) at java.lang.reflect.Method.invoke(Native Method) at androidx.appcompat.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:397) at android.view.View.performClick(View.java:7668) at com.google.android.material.button.MaterialButton.performClick(MaterialButton.java:967) at android.view.View.performClickInternal(View.java:7645) at android.view.View.-$$Nest$mperformClickInternal(Unknown Source:0) at android.view.View$PerformClick.run(View.java:30179) at android.os.Handler.handleCallback(Handler.java:958) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:205) at android.os.Looper.loop(Looper.java:294) at android.app.ActivityThread.main(ActivityThread.java:8248) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:552) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:971) Caused by: android.os.RemoteException: Remote stack trace: at com.android.server.wm.ActivityTaskSupervisor.checkStartAnyActivityPermission(ActivityTaskSupervisor.java:1136) at com.android.server.wm.ActivityStarter.executeRequest(ActivityStarter.java:1074) at com.android.server.wm.ActivityStarter.execute(ActivityStarter.java:742) at com.android.server.wm.ActivityTaskManagerService.startActivityAsUser(ActivityTaskManagerService.java:1300) at com.android.server.wm.ActivityTaskManagerService.startActivityAsUser(ActivityTaskManagerService.java:1251) 上面提示了 Permission Denial ，并且 not exported from uid 1000，表示要uid为 1000的情况才能才有权限。
如果adb命令也是同样会报错，除非成功执行了adb root,就有权限拉起 Fragment界面。
（2）报错的代码位置
报错的具体位置很多人可能会以为是在 ActiveServices.java
但是实际是在 ActivityTaskSupervisor.java 里面报错。
framework\base\services\core\java\com\android\server\wm\ActivityTaskSupervisor.java
报错的具体方法：
boolean checkStartAnyActivityPermission(Intent intent, ActivityInfo aInfo, ...) { ... } else if (!aInfo.exported) { msg = "Permission Denial: starting " + intent.toString() + " from " + callerApp + " (pid=" + callingPid + ", uid=" + callingUid + ")" + " not exported from uid " + aInfo.applicationInfo.uid; } else { ... } 系统中设计是未暴露的组件不能随便被其他应用访问，系统应用不受限制。
这个 Fragment 界面对应的 Activity 确实是 隐藏的。
Settings 的 SubSettings Activity在AndroidManifest.xml中的定义：
<activity android:name=".SubSettings" android:exported="false" android:theme="@style/Theme.SubSettings" /> Android系统对于 exported=“false” 的组件，就是做了限制，没办法直接跳过。
（3）拉起Settings Fragment 界面权限小结 ：
1、代码中跳转到Fragment界面就要设置uid权限 2、adb命令跳转到Fragment 就要 root权限 3、还有一种解决方法直接修改Settings应用，把 SubSettings 修改成 android:exported="true" 可以让普通应用直接拉起Fragment界面。 4、Settings中SubSettings的":settings:show_fragment"能使能的原因分析
（1）Intent中读取了是否包含额外参数Extra
//SubSettings没啥实现，主要逻辑在父类中 //要说作用就是控制这个Activity不可见。安全？ public class SubSettings extends SettingsActivity { } //show_fragment 的信息读取 public class SettingsActivity extends SettingsBaseActivity { //额外参数Extra public static final String EXTRA_SHOW_FRAGMENT = ":settings:show_fragment"; //其他参数 public static final String EXTRA_SHOW_FRAGMENT_ARGUMENTS = ":settings:show_fragment_args"; public static final String EXTRA_FRAGMENT_ARG_KEY = ":settings:fragment_args_key"; //读取Extra 判断是哪个Fragment @VisibleForTesting public String getInitialFragmentName(Intent intent) { return intent.getStringExtra(EXTRA_SHOW_FRAGMENT); } //show_fragment最重要使能的原因是Activity onCreate中有读取是否要跳转到某个Fragment @Override protected void onCreate(Bundle savedState) { // Should happen before any call to getIntent() getMetaData(); final Intent intent = getIntent(); super.onCreate(savedState); Log.d(LOG_TAG, "Starting onCreate"); //根据Intent信息，判断是否要跳转到某个Fragment createUiFromIntent(savedState, intent); } ... } 5、拉起Settings 暴露的Activity界面
虽然Settings内部很多Fragment 界面是隐藏的，
但是也有很多暴露的Activity界面，比如主要的，wifi设置、蓝牙设置、关于界面等都是暴露的。
通过查看 AndroidManifest.xml 是可以看到 exported=“true” 暴露的所有Activity界面。
部分界面：
//wifi设置界面 <activity android:name="Settings$WifiSettingsActivity" android:label="@string/wifi_settings" android:icon="@drawable/ic_homepage_network" android:exported="true" android:configChanges="orientation|keyboardHidden|screenSize"> <intent-filter android:priority="1"> //可以使用Action进行跳转 <action android:name="android.settings.WIFI_SETTINGS"/> </intent-filter> </activity> //蓝牙设置界面，没有Acting咋搞？ <activity-alias android:name="Settings$BluetoothSettingsActivity" android:label="@string/devices_title" android:targetActivity=".Settings$ConnectedDeviceDashboardActivity" android:exported="true"> <intent-filter android:priority="10"> <action android:name="android.intent.action.MAIN" /> <category android:name="com.android.settings.SHORTCUT" /> </intent-filter> </activity-alias> //蓝牙设置界面，可以使用包名跳转 <!-- Keep compatibility with old shortcuts. --> <activity-alias android:name=".bluetooth.BluetoothSettings" android:label="@string/devices_title" android:targetActivity="Settings$BluetoothSettingsActivity" android:exported="true" android:clearTaskOnLaunch="true"> </activity-alias> //p2p设置界面，没有acting咋搞？ <activity android:name="Settings$WifiP2pSettingsActivity" android:exported="true"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.VOICE_LAUNCH" /> </intent-filter> </activity> (1) adb 拉起设置界面 命令：
//方式一：使用action C:\Users\As11040>adb shell am start -a android.settings.WIFI_SETTINGS Starting: Intent { act=android.settings.WIFI_SETTINGS } //方式二：包名类名 C:\Users\As11040>adb shell am start -n com.android.settings/.Settings$BluetoothSettingsActivity Starting: Intent { cmp=com.android.settings/.Settings } 第二种方法没啥用啊，只是拉起的Settings的主界面。 //研究了一下发现，linux中$符合要\转义才能识别，所以正确的命令是： C:\Users\As11040>adb shell am start -n com.android.settings/.Settings\$BluetoothSettingsActivity Starting: Intent { cmp=com.android.settings/.Settings$BluetoothSettingsActivity } C:\Users\As11040> 这下就拉起了蓝牙设置界面 (2)Java 拉起设置界面 命令：
//跳转到Settings应用wifi设置界面 public void jumpMain(View view) { Intent intent = new Intent(); //方式1，指定action： //intent.setAction("android.settings.WIFI_SETTINGS"); //方式2:，指定包名和类名,这里内部类$不用转义 intent.setClassName("com.android.settings","com.android.settings.Settings$WifiSettingsActivity"); intent.setPackage("Settings$WifiSettingsActivity"); startActivity(intent); } (3)Android 暴露的常用界面列表：

/* empty */ } /** * Activity for OneHandedSettings */ public static class OneHandedSettingsActivity extends SettingsActivity { /* empty */ } } 上面这些Activity 都是Settings的内部类，是暴露的Activity，根据命名大概可以猜测到界面的作用，
上面这些Activity可以通过代码或者adb命令拉起。
Settings中也有部分Activity不是Settings的内部类，需要查看AndroidManifest.xml 是否包含exported=“true”，看该Activity是不是暴露的。
6、拉起Settings界面小结
（1）拉起Settings某个Fragment界面
SubSettings默认是隐藏的，所以需要系统uid权限，adb拉起要root权限，或者修改Settings设置 exported=“true”。
虽然拉起Settings某个Fragment界面不太常用，但是对于某些要求比较具体功能界面的需求还是有用的。比较不友好的就是需要系统权限。
（2）拉起Settings某个Activity界面
可以在AndroidManifest.xml中查看存在的Activity界面
查看到 exported=“true” 就是暴露的Activity界面
其中Settings$XXActvity ，是内部类的Activity，也是可以用代码或者adb 拉起的。
拉起Activity，这个确实比较常用并且不用权限，缺点就是只能拉起比较外部的界面，
部分Activity也是通过额外参数控制进入某个Fragment界面的，需要查看实际代码才知道。
