Android网络连接判断与相关处理

本文为大家分享了Android网络连接判断与相关处理，供大家参考，具体内容如下

获取网络信息需要在AndroidManifest.xml文件中加入相应的权限。
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 

1）判断是否有网络连接 

 public boolean isNetworkConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); 
   if (mNetworkInfo != null) { 
    return mNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 } 

2）判断WIFI网络是否可用

 public boolean isWifiConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mWiFiNetworkInfo = mConnectivityManager 
     .getNetworkInfo(ConnectivityManager.TYPE_WIFI); 
   if (mWiFiNetworkInfo != null) { 
    return mWiFiNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 }

3）判断MOBILE网络是否可用

 public boolean isMobileConnected(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mMobileNetworkInfo = mConnectivityManager 
     .getNetworkInfo(ConnectivityManager.TYPE_MOBILE); 
   if (mMobileNetworkInfo != null) { 
    return mMobileNetworkInfo.isAvailable(); 
   } 
  } 
  return false; 
 } 

 4）获取当前网络连接的类型信息 

 public static int getConnectedType(Context context) { 
  if (context != null) { 
   ConnectivityManager mConnectivityManager = (ConnectivityManager) context 
     .getSystemService(Context.CONNECTIVITY_SERVICE); 
   NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); 
   if (mNetworkInfo != null && mNetworkInfo.isAvailable()) { 
    return mNetworkInfo.getType(); 
   } 
  } 
  return -1; 
 }
