Android手机开发：Intent和Broadcast

1. 构造Intent，发送广播

static final String ACTION_1 = "com.eoeandroid.action.NEW_BROADCAST_1";
Intent intent = new Intent(ACTION_1);
sendBroadcast(intent);

2. 继承BroadcastReceiver类，实现一个广播接受类

public class EoeAndroidReceiver extends BroadcastReceiver {
Context context;

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
this.context = context;
//接受信息并处理
}
}

3. 注册和注销BroadcastReceiver

方法1：在AndroidManifest.xml中注册

<receiver android:name="EoeAndroidReceiver1">
<intent-filter>
<action
android:name="com.eoeandroid.action.NEW_BROADCAST_1"/>
</intent-filter>
</receiver>

方法2：直接在代码中注册

IntentFilter filter = new IntentFilter(NEW_BROADCAST);
EoeAndroidReceiver eoeAR = new EoeAndroidReceiver();
registerReceiver(eoeAR, filter);

注销

unregisterReceiver(eoeAR);
