Android手机开发：Intent和Broadcast

来源：互联网发布：higo软件下载编辑：程序博客网时间：2024/06/10 01:53

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;@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubthis.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><actionandroid: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);
