网络监听器Android

我想检查Android手机的网络何时关闭。我可以捕获该事件吗?

我没有得到正确的API或任何可以解释相同内容的示例。如果有人做过或有任何示例链接将非常有帮助。

回答:

新的Java类:

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();

}

}

}

你的AndroidManifest.xml中“ manifest”元素下的新xml:

<!-- Needed to check when the network connection changes -->

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

你的AndroidManifest.xml中“ application”元素下的新xml:

<receiver android:name="com.blackboard.androidtest.receiver.ConnectionChangeReceiver"

android:label="NetworkConnection">

<intent-filter>

<action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>

</intent-filter>

</receiver>
