两种例子

01 /** 02 * 移动网络开关 03 */ 04 privatevoidtoggleMobileData(Context context,booleanenabled) { 05 ConnectivityManager conMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 06 Class<?> conMgrClass =null;// ConnectivityManager类 07 Field iConMgrField =null;// ConnectivityManager类中的字段 08 Object iConMgr =null;// IConnectivityManager类的引用 09 Class<?> iConMgrClass =null;// IConnectivityManager类 10 Method setMobileDataEnabledMethod =null;// setMobileDataEnabled方法 11 try{ 12 // 取得ConnectivityManager类 13 conMgrClass = Class.forName(conMgr.getClass().getName()); 14 // 取得ConnectivityManager类中的对象mService 15 iConMgrField = conMgrClass.getDeclaredField("mService"); 16 // 设置mService可访问 17 iConMgrField.setAccessible(true); 18 // 取得mService的实例化类IConnectivityManager 19 iConMgr = iConMgrField.get(conMgr); 20 // 取得IConnectivityManager类 21 iConMgrClass = Class.forName(iConMgr.getClass().getName()); 22 // 取得IConnectivityManager类中的setMobileDataEnabled(boolean)方法 23 setMobileDataEnabledMethod = iConMgrClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE); 24 // 设置setMobileDataEnabled方法可访问 25 setMobileDataEnabledMethod.setAccessible(true); 26 // 调用setMobileDataEnabled方法 27 setMobileDataEnabledMethod.invoke(iConMgr, enabled); 28 }catch(ClassNotFoundException e) { 29 e.printStackTrace(); 30 }catch(NoSuchFieldException e) { 31 e.printStackTrace(); 32 }catch(SecurityException e) { 33 e.printStackTrace(); 34 }catch(NoSuchMethodException e) { 35 e.printStackTrace(); 36 }catch(IllegalArgumentException e) { 37 e.printStackTrace(); 38 }catch(IllegalAccessException e) { 39 e.printStackTrace(); 40 }catch(InvocationTargetException e) { 41 e.printStackTrace(); 42 } 43 }

第二种

01 privatevoidsetMobileDataEnabled(Context context,booleanenabled) { 02 finalString TAG ="setMobileDataEnabled"; 03 finalConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 04 Class conmanClass; 05 try{ 06 conmanClass = Class.forName(conman.getClass().getName()); 07 finalField iConnectivityManagerField = conmanClass.getDeclaredField("mService"); 08 iConnectivityManagerField.setAccessible(true); 09 finalObject iConnectivityManager = iConnectivityManagerField.get(conman); 10 finalClass iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName()); 11 finalMethod setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE); 12 setMobileDataEnabledMethod.setAccessible(true); 13 14 setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled); 15 }catch(ClassNotFoundException e) { 16 // TODO Auto-generated catch block 17 Log.d(TAG,"ClassNotFoundException"); 18 }catch(NoSuchFieldException e) { 19 Log.d(TAG,"NoSuchFieldException"); 20 }catch(IllegalArgumentException e) { 21 Log.d(TAG,"IllegalArgumentException"); 22 }catch(IllegalAccessException e) { 23 Log.d(TAG,"IllegalAccessException"); 24 }catch(NoSuchMethodException e) { 25 Log.d(TAG,"NoSuchMethodException"); 26 }catch(InvocationTargetException e) { 27 Log.d(TAG,"InvocationTargetException"); 28 }finally{ 29 30 } 31 32 }

打开GPS，在2.3.5系统测试可以通过，在4.1.1系统中测试无效

01 /** 02 * <p>GPS开关 03 * <p>当前若关则打开 04 * <p>当前若开则关闭 05 */ 06 privatevoidtoggleGPS() { 07 Intent gpsIntent =newIntent(); 08 gpsIntent.setClassName("com.android.settings","com.android.settings.widget.SettingsAppWidgetProvider"); 09 gpsIntent.addCategory("android.intent.category.ALTERNATIVE"); gpsIntent.setData(Uri.parse("custom:3")); 10 try{ 11 PendingIntent.getBroadcast(this,0, gpsIntent,0).send(); 12 }catch(CanceledException e) { 13 e.printStackTrace(); 14 } 15 }
