android5.1 增加ethernet设置(DHCP与Static ip)

旧城等待， 2022-07-27 15:51 213阅读 0赞

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

<dashboard-tile
    		    android: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

<string name="ethernet_settings">Ethernet</string>
        
        <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>
        
        <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

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 version="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">
            <Preference
                android: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_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:

![SouthEast 1][]

配制界面

![SouthEast 2][]

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 hclydao
    		new 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 hclydao
    	void 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 eth0
                                continue;

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>
    	
    	<FrameLayout
    	    android:id="@+id/ethernet_combo"
    	    android:layout_height="wrap_content"
    	    android:layout_width="wrap_content"
    	    android:layout_marginRight="-6dp"
    	    >
    	    <ImageView
    	        android: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

<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 hclydao
            int 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 hclydao
        private int mEthernetStateId = 0;
    	private int mEthernetDescription;
        ViewGroup mWifiGroup,mEthernetGroup;//modify by hclydao
        ImageView 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 hclydao
            mEthernet       = (ImageView) findViewById(R.id.ethernet_state);

在

mWifi           = null;  
         mAirplane       = null;

后增加

mEthernetGroup  = null;//add by hclydao
            mEthernet	    = null;

增加函数

//add by hclydao
    	@Override
        public 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 hclydao
                mEthernetGroup.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

|| mEthernetVisible

最后效果图如下:
