Android中action的定义

一、在AndroidManifest.xml中定义action事件

<serviceandroid:name=".service.NettyService">            <intent-filter>                <action android:name="com.hovans.netty.ACTION_CHECK_SESSION" />                <action android:name="com.hovans.netty.ACTION_HEARTBEAT" />                <action android:name="com.hovans.netty.ACTION_CONNECT_SESSION" />                <action android:name="com.hovans.netty.ACTION_DISCONNECT_SESSION" />            </intent-filter>        </service>

二、定义一个Intent类

public class NettyIntent {public static final String ACTION_CHECK_SESSION = "com.hovans.netty.ACTION_CHECK_SESSION";public static final String ACTION_HEARTBEAT = "com.hovans.netty.ACTION_HEARTBEAT";public static final String ACTION_CONNECT_SESSION = "com.hovans.netty.ACTION_CONNECT_SESSION";public static final String ACTION_DISCONNECT_SESSION = "com.hovans.netty.ACTION_DISCONNECT_SESSION";}

三、action出发示例代码：

public void onStartClick(View view) {System.out.println("duanliang,HomeActivity.onStartClick");startService(new Intent(NettyIntent.ACTION_CONNECT_SESSION));}

四、action响应示例代码：

public void onWorkerRequest(Intent intent, int i) {if (NettyIntent.ACTION_CONNECT_SESSION.equals(intent.getAction())) {if(mChannel != null) {disconnectSessionIfItNeeds();}connectSessionIfItNeeds();} else if(NettyIntent.ACTION_HEARTBEAT.equals(intent.getAction())) {if(checkConnection() == false) {connectSessionIfItNeeds();}} else if(NettyIntent.ACTION_CHECK_SESSION.equals(intent.getAction())) {scheduleToReconnect();} else if(NettyIntent.ACTION_DISCONNECT_SESSION.equals(intent.getAction())) {disconnectSessionIfItNeeds();}}

其中onWorkerRequest(Intent intent, int i)的定义见博文（待补充）
