android 如何实现移动数据上网的开关？之前百度了一下，找到几篇，但都说不行，今天再搜索，想试一试，竟都不见了！特来此求肋。谢谢
感谢名位的回答，虽然没有用到，但也是学到了些东西的。本人已经找到了解决办法，也在此分享吧：
解决办法中使用到了ConnectivityManager类，但是在SDK中的ConnectivityManager类并没有提供setMobileDataEnable()、getMobileDataEnable()等方法。也看了ConnectivityManager类的源码，里面都是有这些方法的。弄了大半天，最终狠下心来，自己写个ConnectivityManager类，其中的方法和源ConnectivityManager类的方法一样，但都是空实现，编译成ConnectivityManager.class文件，然后替换android.jar包中的android.net.ConnectivityManager.class文件。然后在项目中，使用ConnectivityManager的setMobileDataEnable()方法来打开和关闭数据上网，使用getMobileDataEnable()方法获得当前连接状态，当然这需要android.permission.CHANGE_NETWORK_STATE和android.permission.ACCESS_NETWORK_STATE权限。
ConnectivityManager类如下：
package android.net;

这个是一种方法，但是对有些手机可能无法实现，我的可以，你可以试一下
Java code
@SuppressWarnings("unchecked")
public void openDataConnect() throws ClassNotFoundException,
SecurityException, NoSuchMethodException, IllegalArgumentException,
IllegalAccessException, InvocationTargetException {
Method dataConnSwitchmethod;
Class telephonyManagerClass;
Object ITelephonyStub;
Class ITelephonyClass;
boolean isEnabled = false;
TelephonyManager telephonyManager = (TelephonyManager) context.get()
.getSystemService(Context.TELEPHONY_SERVICE);
//获取当前的状态
if(telephonyManager.getDataState() == TelephonyManager.DATA_CONNECTED){
isEnabled = true;
}else{
isEnabled = false;
}
telephonyManagerClass = Class.forName(telephonyManager.getClass().getName());
Method getITelephonyMethod = telephonyManagerClass.getDeclaredMethod("getITelephony");
getITelephonyMethod.setAccessible(true);
ITelephonyStub = getITelephonyMethod.invoke(telephonyManager);
ITelephonyClass = Class.forName(ITelephonyStub.getClass().getName());
if (isEnabled) {
dataConnSwitchmethod = ITelephonyClass
.getDeclaredMethod("disableDataConnectivity");
} else {
dataConnSwitchmethod = ITelephonyClass
.getDeclaredMethod("enableDataConnectivity");
}
dataConnSwitchmethod.setAccessible(true);
dataConnSwitchmethod.invoke(ITelephonyStub);
}
android APN的打开与关闭
由于Android对于APN的网络API没有公开，不过我们可以阅读源代码，然后进行数
据库操作，系统会自动监听数据库的变化，从而实现开启或者关闭APN。
大家可以研究一下frameworks/base/core/java/android/provider
/Telephony.java这个类，
比较重要的就是 URI 和数据库字段： content://telephony/carriers
字段可以在Telephony.java中找到。
其实原理很简单 ：
1 、 当开启APN的时候，设置一个正确的移动或者联通的APN
2、 关闭的时候设置一个错误APN就会自动关闭网络
看代码：Activity：
Java代码
package cc.mdev.apn;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.ContentValues;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
public class Main extends Activity {
Uri uri = Uri.parse("content://telephony/carriers");
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button open= (Button) findViewById(R.id.open);
Button close= (Button) findViewById(R.id.close);
open.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openAPN();
}
});
close.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
closeAPN();
}
});
}
public void openAPN(){
List<APN> list = getAPNList();
for (APN apn : list) {
ContentValues cv = new ContentValues();
cv.put("apn", APNMatchTools.matchAPN(apn.apn));
cv.put("type", APNMatchTools.matchAPN(apn.type));
getContentResolver().update(uri, cv, "_id=?", new String[]{apn.id});
}
}
public void closeAPN(){
List<APN> list = getAPNList();
for (APN apn : list) {
ContentValues cv = new ContentValues();
cv.put("apn", APNMatchTools.matchAPN(apn.apn)+"mdev");
cv.put("type", APNMatchTools.matchAPN(apn.type)+"mdev");
getContentResolver().update(uri, cv, "_id=?", new String[]{apn.id});
}
}
private List<APN> getAPNList(){
String tag = "Main.getAPNList()";
//current不为空表示可以使用的APN
String projection[] = {"_id,apn,type,current"};
Cursor cr = this.getContentResolver().query(uri, projection, null, null, null);
List<APN> list = new ArrayList<APN>();
while(cr!=null && cr.moveToNext()){
Log.d(tag, cr.getString(cr.getColumnIndex("_id")) + " " + cr.getString(cr.getColumnIndex("apn")) + " " + cr.getString(cr.getColumnIndex("type"))+ " " + cr.getString(cr.getColumnIndex("current")));
APN a = new APN();
a.id = cr.getString(cr.getColumnIndex("_id"));
a.apn = cr.getString(cr.getColumnIndex("apn"));
a.type = cr.getString(cr.getColumnIndex("type"));
list.add(a);
}
if(cr!=null)
cr.close();
return list;
}
public static class APN{
String id;
String apn;
String type;
}
}
APNMatchTools.java
Java代码
package cc.mdev.apn;
public final class APNMatchTools {
public static class APNNet{
public static String CMWAP = "cmwap";
public static String CMNET = "cmnet";
//中国联通3GWAP设置 中国联通3G因特网设置 中国联通WAP设置 中国联通因特网设置
//3gwap 3gnet uniwap uninet
public static String GWAP_3 = "3gwap";
public static String GNET_3="3gnet";
public static String UNIWAP="uniwap";
public static String UNINET="uninet";
}
public static String matchAPN(String currentName) {
if("".equals(currentName) || null==currentName){
return "";
}
currentName = currentName.toLowerCase();
if(currentName.startsWith(APNNet.CMNET))
return APNNet.CMNET;
else if(currentName.startsWith(APNNet.CMWAP))
return APNNet.CMWAP;
else if(currentName.startsWith(APNNet.GNET_3))
return APNNet.GNET_3;
else if(currentName.startsWith(APNNet.GWAP_3))
return APNNet.GWAP_3;
else if(currentName.startsWith(APNNet.UNINET))
return APNNet.UNINET;
else if(currentName.startsWith(APNNet.UNIWAP))
return APNNet.UNIWAP;
else if(currentName.startsWith("default"))
return "default";
else return "";
// return currentName.substring(0, currentName.length() - SUFFIX.length());
}
}
最后不要忘记加上修改APN的权限：
Xml代码
1. <uses-permission android:name="android.permission.WRITE_APN_SETTINGS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_APN_SETTINGS"></uses-permission>
经过测试在G1 上联通和移动卡均是成功的。
在frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\tablet\SettingsView.java路径下
public class SettingsView extends LinearLayout implements View.OnClickListener{
//增加数据广播实例声明
DataEnabledController mDataEnabled;
...
//在该方法下增加~
protected void onFinishInflate() {
...
mDataEnabled = new DataEnabledController(context,
(CompoundButton)findViewById(R.id.dataEnable_checkbox));
}
}
再在SystemUI\res下相应的xml布局文件内加入
<LinearLayout
android:id="@+id/dataEnable"
style="@style/StatusBarPanelSettingsRow"
>
<ImageView
android:id="@+id/dataEnable_icon"
style="@style/StatusBarPanelSettingsIcon"
android:src="@drawable/ic_sysbar_data_switcher"
/>
<TextView
android:id="@+id/dataEnable_label"
style="@style/StatusBarPanelSettingsContents"
android:text="@string/status_bar_settings_data_enabled"
/>
<Switch
android:id="@+id/dataEnable_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginRight="5dp"
/>
</LinearLayout>
<View style="@style/StatusBarPanelSettingsPanelSeparator" />
最后在SystemUI\res下加入相应资源图片和字符串即可~ 希望对你有所帮助~
4.0 以后的 Android 不在提供普通应用程序对 APN(Access Point Name) 修改的权限，如果强制修改的话，会报安全异常直接挂掉的。除非有当前设备系统应用的签名，然后打包进你修改 APN 的应用里面。
2.x 的系统可以尝试一下以下代码，
public static boolean setNETMode()
{
ContentResolver resolver = context.getContentResolver();
Cursor cursor =
resolver.query(Uri.parse("content://telephony/carriers"),
new String[] { "_id" }, "apn like '%net' and current=1", null,
null);
if ((cursor != null) && (cursor.moveToNext()))
{
ContentValues values = new ContentValues();
values.put("apn_id", cursor.getString(0));
resolver.update(
Uri.parse("content://telephony/carriers/preferapn"), values,
null, null);
return true;
}
return false;
}
一般的移动网络开关都是通过篡改APN实现的(真正的开关没有直接对外的api)：
如接入点名称类型一般是default,当关闭的时候修改为其他的值，打开时候修改为default.
是哇，可以用反射来实现吧？
1、调用隐藏的方法可以在源代码中进行编译
2、利用反射
希望下面文章对你有帮助

用我这个方法绝对好使，适用于任何手机。不需要放到系统里编译，也不需要导入jar包。
public void setMobileDataStatus(Context context, boolean enabled)
{
ConnectivityManager conMgr = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
// ConnectivityManager类
Class<?> conMgrClass = null;
// ConnectivityManager类中的字段
Field iConMgrField = null;
// IConnectivityManager类的引用
Object iConMgr = null;
// IConnectivityManager类
Class<?> iConMgrClass = null;
// setMobileDataEnabled方法
Method setMobileDataEnabledMethod = null;
try {
// 取得ConnectivityManager类
conMgrClass = Class.forName(conMgr.getClass().getName());
// 取得ConnectivityManager类中的对象Mservice
iConMgrField = conMgrClass.getDeclaredField("mService");
// 设置mService可访问
iConMgrField.setAccessible(true);
// 取得mService的实例化类IConnectivityManager
iConMgr = iConMgrField.get(conMgr);
// 取得IConnectivityManager类
iConMgrClass = Class.forName(iConMgr.getClass().getName());
// 取得IConnectivityManager类中的setMobileDataEnabled(boolean)方法
setMobileDataEnabledMethod = iConMgrClass.getDeclaredMethod(
"setMobileDataEnabled", Boolean.TYPE);
// 设置setMobileDataEnabled方法是否可访问
setMobileDataEnabledMethod.setAccessible(true);
// 调用setMobileDataEnabled方法
setMobileDataEnabledMethod.invoke(iConMgr, enabled);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
设置-》流量使用情况
我的是在这里能够开关
不过我不知道各个手机的情况一样不，我的系统是android4.1.1
不知道楼主是想用代码实现还是手机功能？我是按照手机功能回答的
