Android 判斷網絡狀態

Android 判斷網絡狀態這一應用技巧在實際應中是比較重要的。那麼，在Android操作系統中，如何能夠正確的判斷我們所連接的網絡是否斷開恩？今天我們就針對這一應用技巧進行一個詳細的分析。

public class ConnectionChangeReceiver extends
BroadcastReceiver  
{  
@Override  
public void onReceive( Context context, Intent intent )  
{  
ConnectivityManager connectivityManager =
(ConnectivityManager) context.getSystemService
( Context.CONNECTIVITY_SERVICE );  
NetworkInfo activeNetInfo = connectivityManager.
getActiveNetworkInfo();  
NetworkInfo mobNetInfo = connectivityManager.getNetworkInfo
( ConnectivityManager.TYPE_MOBILE );  
if ( activeNetInfo != null )  
{  
Toast.makeText( context, "Active Network Type : " +
activeNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();  
}  
if( mobNetInfo != null )  
{  
Toast.makeText( context, "Mobile Network Type : " +
mobNetInfo.getTypeName(), Toast.LENGTH_SHORT ).show();  
}  
}  
}  
< !-- Needed to check when the network connection changes -->  
< uses-permission android:name="android.permission.
ACCESS_NETWORK_STATE"/>  
< receiver android:name="com.blackboard.androidtest.
receiver.ConnectionChangeReceiver"  
android:label="NetworkConnection">  
< intent-filter>  
< action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>  
< /intent-filter>  
< /receiver>
