Android原生设置Settings 具体Fragment和Activity界面跳转实现

Android原生设置Settings 具体Fragment和Activity界面跳转实现

文章目录

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/

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 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:

Settings\src\com\android\settings\Settings.java

里面有很多内部类的Activity都是暴露的Activity界面。

部分 Activity如下:

public class Settings extends SettingsActivity {

    public static class MemtagPageActivity extends SettingsActivity { /* empty */}
    public static class AssistGestureSettingsActivity extends SettingsActivity { /* empty */}
    public static class BluetoothSettingsActivity extends SettingsActivity { /* empty */ }

            setTheme(R.style.SettingsPreferenceTheme_SetupWizard);
            ThemeHelper.trySetDynamicColor(this);
            super.onCreate(savedState);
        }
    }

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。
