android5.1 增加ethernet設定(DHCP與Static ip)
阿新 • • 發佈：2019-02-14
android5.0以上的系統自帶了ethernet service，預設開機就會啟動，預設ip獲取方式是動態分配，這裡記錄下android5.1增加ethernet設定介面設定ip獲取方式及開關.
首先是介面方面要修改Settings增加ethernet設定介面
修改檔案packages/apps/Settings/res/xml/dashboard_categories.xml在藍芽後面加上如下程式碼
<!-- ethernet add by hclydao--> <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後面進行說明，然後增加string修改檔案packages/apps/Settings/res/values/strings.xml
增加如下內容
這是我修改完成後所要加的所有的string<!-- 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 network prefix of the network [CHAR LIMIT=25]--> <string name="eth_network_prefix_length">Network prefix length</string>
接著修改檔案packages/apps/Settings/src/com/android/settings/SettingsActivity.java增加
import com.android.settings.ethernet.EthernetSettings;//add by hclydao然後在R.id.bluetooth_settings,後增加
R.id.ethernet_settings,//add by hclydao在BluetoothSettings.class.getName(),後增加
EthernetSettings.class.getName(),//add by hclydao
接著修改檔案packages/apps/Settings/src/com/android/settings/Settings.java
在public static class WirelessSettingsActivity extends SettingsActivity { /* empty */ }後增加
public static class EthernetSettingsActivity extends SettingsActivity { /* empty */ } //add by hclydao這裡面應該是宣告與繼承關係
接著修改
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="com.android.settings.ethernet.EthernetSettings" />
<meta-data android:name="com.android.settings.TOP_LEVEL_HEADER_ID"
android:resource="@id/ethernet_settings" />
<meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED"
android:value="true" />
</activity>然後增加點選進去後的佈局檔案,增加
packages/apps/Settings/res/xml/ethernet_settings.xml
內容如下

</PreferenceScreen>這是我最終的程式碼，這裡就不貼上來了，下面我會給下載地址
編譯後效果應該是這個樣子的:
點選進去後會有一個Dialog佈局，需要增加檔案packages/apps/Settings/res/layout/eth_configure.xml

</LinearLayout>
</ScrollView>裡面包括了dhcp與static ip的選擇，以及static ip的設定
以及packages/apps/Settings/src/com/android/settings/ethernet/EthernetSettings.java
這些是具體的實現，最後我會給下載地址
最後出來的效果應該是這樣的:
配製介面
增加這些修改和檔案後，基本上就可以進行動態設定了。但是設定的關於ethernet的開關是沒有作用的，所以這裡增加開關的控制
修改檔案frameworks/base/core/java/android/provider/Settings.java
在Settings資料庫中增加一個ethernet的控制
public static final String ETHERNET_ON = "ethernet_on";//add by hclydao修改frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetServiceImpl.java檔案
在mHandler = new Handler(handlerThread.getLooper());後增加如下程式碼
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;
}如果沒有開啟就直接返回，不啟動Service後繼的操作,然後增加兩個介面
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();
}同時要修改frameworks/base/core/java/android/net/EthernetManager.java檔案增加
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) {
}
}同時修改frameworks/base/core/java/android/net/IEthernetManager.aidl
增加
void Trackstart();//add by hclydao
void Trackstop();跟蹤測試時發現靜態ip設定的時候有時候不成功，修改檔案frameworks/opt/net/ethernet/java/com/android/server/ethernet/EthernetNetworkFactory.java
增加
private Handler mHandler;mContext = context;
後增加
mHandler = target;//add by hclydao在if (!setStaticIpAddress(config.getStaticIpConfiguration())) {後增加
//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);
}然後在if (mNMService.getInterfaceConfig(iface).hasFlag("running")) {前面增加
if(!iface.equals("eth0"))//add by hclydao make sure the interface is eth0
continue;這裡只設置了一個裝置名，為儲存是eth0所以加上這句,防止意外.
最後來增加Systemui statusbar中的狀態提示,這裡只增加了兩種狀態，一種是連線成功，一種是連線不成功，簡單點來
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-->
<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>修改檔案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>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);mWifiSignalController.setInetCondition(
mValidatedTransports.get(mWifiSignalController.getTransportType()) ? 1 : 0);
後面增加
//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);後增加
public void setEthernetIndicators(boolean visible, int stateIcon, int contentDescription);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);
後增加
mEthernetGroup = (ViewGroup) findViewById(R.id.ethernet_combo);//add by hclydao
mEthernet = (ImageView) findViewById(R.id.ethernet_state);在
mWifi = null;mAirplane = null;
後增加
mEthernetGroup = null;//add by hclydao
mEthernet = null;增加函式
//add by hclydao
@Override
public void setEthernetIndicators(boolean visible, int stateIcon, int contentDescription) {
mEthernetVisible = visible;
mEthernetStateId = stateIcon;
mEthernetDescription = contentDescription;
apply();
}mWifiSignalSpacer.setVisibility(View.GONE);
}
後增加
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最後效果圖如下:
