[摘要：android5.0以上的体系自带了ethernet service，默许开机便会启动，默许ip猎取体式格局是静态分派，那里纪录下android5.1增添ethernet设置界里设置ip猎取体式格局及开闭. 起首是界里圆里]

android5.0以上的系统自带了ethernet service，默认开机就会启动，默认ip获取方式是动态分配，这里记录下android5.1增加ethernet设置界面设置ip获取方式及开关.

首先是界面方面要修改Settings增加ethernet设置界面

修改文件packages/apps/Settings/res/xml/dashboard_categories.xml在蓝牙后面加上如下代码

<!-- ethernet add by hclydao--><dashboard-tileandroid:id="@+id/ethernet_settings"android:icon="@drawable/ic_settings_dock"android:fragment="com.android.settings.ethernet.EthernetSettings"android:title="@string/ethernet_settings" />

其中的EthernetSettings后面进行说明，然后增加string修改文件packages/apps/Settings/res/values/strings.xml

增加如下内容

<!-- Eth settings title add by hclydao--><string name="ethernet_settings">Ethernet</string><!-- Ethernet configuration dialog add by hcldyao--><string name="eth_config_title">Configure Ethernet device</string><string name="eth_setting">Ethernet</string><string name="eth_dev_list">Ethernet Devices:</string><string name="eth_con_type">Connection Type</string><string name="eth_con_type_dhcp">DHCP</string><string name="eth_con_type_manual">Static IP</string><string name="eth_dns">DNS address</string><string name="eth_gw">Gateway address</string><string name="eth_ipaddr">IP address</string><string name="eth_quick_toggle_title">Ethernet</string><string name="eth_quick_toggle_summary">Turn on Ethernet</string><string name="eth_conf_perf_title">Ethernet configuration</string><string name="eth_conf_summary">Configure Ethernet devices</string><string name="eth_mask">Netmask</string><string name="eth_toggle_summary_off">Turn off Ethernet</string><string name="eth_toggle_summary_on">Turn on Ethernet</string><string name="eth_settings_error">Failed to set: Please enter the valid characters 0~255</string><string name="eth_settings_empty">can\'t be empty</string><!-- Label for the <a target=_blank href="http://www.07net01.com/tags-Network-0.html" target="_blank" class="infotextkey" style="box-sizing: border-box; background-color: transparent; color: rgb(66, 139, 202);">Network</a> prefix of the network [CHAR LIMIT=25]--><string name="eth_network_prefix_length">Network prefix length</string>

这是我修改完成后所要加的所有的string

接着修改文件packages/apps/Settings/src/com/android/settings/SettingsActivity.Java增加

import com.android.settings.ethernet.EthernetSettings;//add by hclydao

然后在R.id.bluetooth_settings,后增加

R.id.ethernet_settings,//add by hclydao

在BluetoothSettings.class.getName(),后增加

EthernetSettings.class.getName(),//add by hclydao

接着修改文件packages/apps/Settings/src/com/android/settings/Settings.java

在public static class WirelessSettingsActivity extends SettingsActivity { /* empty */ }后增加

public static class EthernetSettingsActivity extends SettingsActivity { /* empty */ } //add by hclydao

这里面应该是声明与继承关系

接着修改
packages/apps/Settings/AndroidManifest.xml

 <activity android:name="Settings$EthernetSettingsActivity"android:label="@string/ethernet_settings"android:taskAffinity=""><intent-filter><action android:name="android.intent.action.MAIN" /><action android:name="com.android.settings.ETHERNET_SETTINGS" /><action android:name="android.settings.ETHERNET_SETTINGS" /><category android:name="android.intent.category.DEFAULT" /><category android:name="android.intent.category.VOICE_LAUNCH" /><category android:name="com.android.settings.SHORTCUT" /></intent-filter><meta-data android:name="com.android.settings.FRAGMENT_CLASS"android:value=http://www.ithao123.cn/"com.android.settings.ethernet.EthernetSettings" /><meta-data android:name="com.android.settings.TOP_LEVEL_HEADER_ID" android:resource="@id/ethernet_settings" style="box-sizing: border-box;"><meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED" android:value="true" style="box-sizing: border-box;"></meta-data></meta-data>

这三个文件按照WIFI的代码改就行了。
然后增加点击进去后的布局文件,增加
packages/apps/Settings/res/xml/ethernet_settings.xml

内容如下

<?xml <a target=_blank href="http://www.07net01.com/tags-version-0.html" target="_blank" class="infotextkey" style="box-sizing: border-box; background-color: transparent; color: rgb(66, 139, 202);">version</a>="1.0" encoding="utf-8"?>

--><PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"android:title="@string/ethernet_settings"xmlns:settings="http://schemas.android.com/apk/res/com.android.settings"><Preferenceandroid:title="@string/eth_conf_perf_title"android:summary="@string/eth_conf_summary"android:key="ETHERNET_CONFIG"android:persistent="false" />
</PreferenceScreen>

然后增加了packages/apps/Settings/src/com/android/settings/ethernet/EthernetSettings.java

这是我最终的代码，这里就不贴上来了，下面我会给下载地址
编译后效果应该是这个样子的:

点击进去后会有一个Dialog布局，需要增加文件packages/apps/Settings/res/layout/eth_configure.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"><LinearLayoutandroid:layout_width="fill_parent"android:layout_height="wrap_content"android:padding="8dip"android:orientation="vertical"><LinearLayoutandroid:id="@+id/table"android:layout_width="fill_parent"android:layout_height="fill_parent"android:orientation="vertical"></LinearLayout><!-- Connection type --><TextView android:id="@+id/eth_con_type"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_con_type" /><RadioGroup android:id="@+id/con_type"android:layout_width="fill_parent"android:layout_height="wrap_content"><RadioButton android:id="@+id/dhcp_radio"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="@string/eth_con_type_dhcp"></RadioButton><RadioButton android:id="@+id/manual_radio"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:text="@string/eth_con_type_manual"></RadioButton></RadioGroup><!-- IP address --><LinearLayout android:id="@+id/enterprise_wrapper"android:layout_width="fill_parent"android:layout_height="wrap_content"android:padding="0dip"android:orientation="vertical"><TextView android:id="@+id/ipaddr_text"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_ipaddr" /><EditText android:id="@+id/ipaddr_edit"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="2dip"android:singleLine="true" />
<!--<TextView android:id="@+id/netmask_text"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_mask" /><EditText android:id="@+id/netmask_edit"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="2dip"android:singleLine="true" />
--><TextView android:id="@+id/prefix_text"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_network_prefix_length" /><EditText android:id="@+id/prefix_edit"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="2dip"android:singleLine="true" /><TextView android:id="@+id/dns_text"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_dns" /><EditText android:id="@+id/eth_dns_edit"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="2dip"android:singleLine="true" /><TextView android:id="@+id/gw_text"style="?android:attr/textAppearanceSmall"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="8dip"android:text="@string/eth_gw" /><EditText android:id="@+id/eth_gw_edit"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_marginTop="2dip"android:singleLine="true" /></LinearLayout></LinearLayout></ScrollView>

里面包括了dhcp与static ip的选择，以及static ip的设置

然后增加Settings/src/com/android/settings/ethernet/EthernetDialog.java
以及packages/apps/Settings/src/com/android/settings/ethernet/EthernetSettings.java
这些是具体的实现，最后我会给下载地址
最后出来的效果应该是这样的:

配制界面

增加这些修改和文件后，基本上就可以进行动态设置了。但是设置的关于ethernet的开关是没有作用的，所以这里增加开关的控制
修改文件frameworks/base/core/java/android/provider/Settings.java
在Settings数据库中增加一个ethernet的控制

public static final String ETHERNET_ON = "ethernet_on";//add by hclydao

增加这个以后需要更新api才能编译过,增加这个后在ethernet-service和Settings中ethernet中进行读写操作

修改frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetServiceImpl.java文件

在mHandler = new Handler(handlerThread.getLooper());后增加如下代码

int enable = Settings.Global.getInt(mContext.getContentResolver(),Settings.Global.ETHERNET_ON,0);//add by hclydao
if(enable != EthernetManager.ETH_STATE_ENABLED) {Log.i(TAG, "Ethernet is not enable");return;
}

如果没有打开就直接返回，不启动Service后继的操作,然后增加两个接口

	class TstartThread extends Thread {public void run() {Looper.prepare();mTracker.start(mContext, mHandler);mStarted.set(true);Looper.loop();}}public void Trackstart() { //add by hclydaonew TstartThread().start();}public void Trackstop() {Log.i(TAG, "Stop Ethernet service");Thread tstopthread = new Thread(new Runnable() {public void run() {Looper.prepare();mTracker.stop();mStarted.set(false);Looper.loop();}});tstopthread.start();}

同时要修改frameworks/base/core/java/android/net/EthernetManager.java文件增加

    public static final int ETH_STATE_UNKNOWN = 0;public static final int ETH_STATE_DISABLED = 1;public static final int ETH_STATE_ENABLED = 2;public void start() {try {mService.Trackstart();} catch (NullPointerException | RemoteException e) {}}public void stop() {try {mService.Trackstop();} catch (NullPointerException | RemoteException e) {}}

同时修改frameworks/base/core/java/android/net/IEthernetManager.aidl

增加

	void Trackstart();//add by hclydaovoid Trackstop();

提供给设置进行状态控制,这里基本功能就实现了。
跟踪测试时发现静态ip设置的时候有时候不成功，修改文件frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactory.java

增加

private Handler mHandler;

然后在

mContext = context;

后增加

mHandler = target;//add by hclydao

在if (!setStaticIpAddress(config.getStaticIpConfiguration())) {后增加

//if error then stop and restart add by hclydao
if((mContext != null) && (mHandler != null)) {Log.d(TAG, "Setting static ip failed now restart");stop();start(mContext,mHandler);
}

如果设置失败，stop后重新start

然后在if (mNMService.getinterfaceConfig(iface).hasFlag("running")) {前面增加

                        if(!iface.equals("eth0"))//add by hclydao make sure the interface is eth0continue;

这里只设置了一个设备名，为保存是eth0所以加上这句,防止意外.

最后来增加systemui statusbar中的状态提示,这里只增加了两种状态，一种是连接成功，一种是连接不成功，简单点来
修改frameworks/base/packages/SystemUI/res/layout/signal_cluster_view.xml
在

     <View
         android:id="@+id/wifi_signal_spacer"
         android:layout_width="4dp"
前增加

</FrameLayout><!--add by hclyado for ethernet--><FrameLayoutandroid:id="@+id/ethernet_combo"android:layout_height="wrap_content"android:layout_width="wrap_content"android:layout_marginRight="-6dp"><ImageViewandroid:id="@+id/ethernet_state"android:layout_height="wrap_content"android:layout_width="wrap_content"android:layout_alignParentRight="true"android:layout_centerVertical="true"android:scaleType="center"/></FrameLayout>

修改文件frameworks/base/packages/SystemUI/res/values/strings.xml
增加

    <!-- Content description of the Ethernet connected icon for accessibility (not shown on the screen). [CHAR LIMIT=NONE] add by hclydao--><string name="accessibility_ethernet_connected">Ethernet connected.</string><string name="accessibility_ethernet_disconnected">Ethernet disconnected.</string><string name="accessibility_ethernet_connecting">Ethernet connecting.</string>

修改文件
frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/policy/NetworkControllerImpl.java

增加

import android.net.EthernetManager;

在mWifiSignalController.notifyListeners();前面加上

cluster.setEthernetIndicators(false,R.drawable.ethernet_disconnected,R.string.accessibility_ethernet_disconnected);

在pushConnectivityToSignals函数中的
mWifiSignalController.setInetCondition(
mValidatedTransports.get(mWifiSignalController.getTransportType()) ? 1 : 0);

后面增加

//add by hclydaoint length = mSignalClusters.size();int ethicon = R.drawable.ethernet_connecting;int ethacc = R.string.accessibility_ethernet_connecting;if(mValidatedTransports.get(TRANSPORT_ETHERNET)) {ethicon = R.drawable.ethernet_connected;ethacc = R.string.accessibility_ethernet_connected;}for (int i = 0; i < length; i++) {mSignalClusters.get(i).setEthernetIndicators(mEthernetConnected, ethicon,ethacc);}
//end add

在

void setIsAirplaneMode(boolean is, int airplaneIcon, int contentDescription);

后增加

public void setEthernetIndicators(boolean visible, int stateIcon, int contentDescription);

修改文件frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/SignalClusterView.java

增加

    private boolean mEthernetVisible = false;//add by hclydaoprivate int mEthernetStateId = 0;private int mEthernetDescription;ViewGroup mWifiGroup,mEthernetGroup;//modify by hclydaoImageView mVpn, mWifi, mAirplane, mNoSims,mEthernet;//modify by hclydao

在

         mWifiAirplaneSpacer =         findViewById(R.id.wifi_airplane_spacer);
         mWifiSignalSpacer =           findViewById(R.id.wifi_signal_spacer);
         mMobileSignalGroup = (LinearLayout) findViewById(R.id.mobile_signal_group);

后增加

        mEthernetGroup  = (ViewGroup) findViewById(R.id.ethernet_combo);//add by hclydaomEthernet       = (ImageView) findViewById(R.id.ethernet_state);

在

mWifi = null;
mAirplane = null;

后增加

        mEthernetGroup  = null;//add by hclydaomEthernet	    = null;

增加函数

	//add by hclydao@Overridepublic void setEthernetIndicators(boolean visible, int stateIcon, int contentDescription) {mEthernetVisible = visible;mEthernetStateId = stateIcon;mEthernetDescription = contentDescription;apply();}

在apply函数中
mWifiSignalSpacer.setVisibility(View.GONE);
}

后增加

        if (mEthernetVisible && !mWifiVisible) {//add by hclydaomEthernetGroup.setVisibility(View.VISIBLE);mEthernet.setImageResource(mEthernetStateId);mEthernetGroup.setContentDescription(mContext.getString(mEthernetDescription));} else {mEthernetGroup.setVisibility(View.GONE);}

在boolean anythingVisible = mNoSimsVisible || mWifiVisible || mIsAirplaneMode上增加
