打开/关闭gprs代码

Question

嗨，我正在处理需要通过代码打开/关闭gprs的应用程序。 我正在使用此方法来检查连接是否打开/关闭。但我不知道如何打开GPRS如果是关闭

代码

NetworkInfo i = conMgr.getActiveNetworkInfo(); 
    if (i == null) 
    return false; 
    if (!i.isConnected()) 
    return false; 
    if (!i.isAvailable()) 
    return false; 
    return true; 

Answer 1

使用此代码Broadcast Wifi或GPRS可用性

BroadcastReceiver br; 
br = new BroadcastReceiver() { 

@Override 
public void onReceive(Context arg0, Intent intent) { 
    // TODO Auto-generated method stub 
     String action = intent.getAction(); 
     if (!action.equals(ConnectivityManager.CONNECTIVITY_ACTION)) 
      { 
       return; 
      } 
    boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false); 
    NetworkInfo aNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);        

     if (!noConnectivity) 
     { 
      if (aNetworkInfo.getType() == ConnectivityManager.TYPE_MOBILE) 
       { 
        Toast.makeText(getApplicationContext(), "Mobile Connected", Toast.LENGTH_LONG).show(); 
         //Handle connected case 
       } 
     if (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI) 
       { 
        Toast.makeText(getApplicationContext(), "WIFI Connected", Toast.LENGTH_LONG).show(); 
       }  
      } 

     else 
     { 
       if ((aNetworkInfo.getType() == ConnectivityManager.TYPE_MOBILE) || 
          (aNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI)) 
        { 
         Toast.makeText(getApplicationContext(), "Not Connected", Toast.LENGTH_LONG).show(); 
        } 
     }    
    } 
}; 

提供以下在AndroidManifest.xml权限

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

而且别忘了register和unregisterBroadcastReceiver。
