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;
}
