android BroadcastReceiver 注册方式

注册BroadcastReceiver 两种方式：

1、静态注册

2、动态注册

静态注册方式：

步骤1：通过Manifest文件注册广播接收器：

<!-- 开机启动完成广播接收器  -->
<receiver android:name="com.spreadtrum.BroadcastReceiver.BootReceiver" android:permission="android.permission.RECEIVE_BOOT_COMPLETED">  
	<intent-filter>
		<action android:name="android.intent.action.BOOT_COMPLETED"></action>
	</intent-filter>
</receiver>

步骤2：编写一个广播接收器类，继承于BroadcastReceiver，并实现onReceive方法：

public class BootReceiver extends BroadcastReceiver {

	private static final String TAG = "BootReceiver";

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		 if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())){
			//处理接收到该广播时的逻辑事务
		 }
	}
}

动态注册

public class MainActivity extends Activity {
	private BroadcastReceiver receiver = null;
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        Log4debug.i(TAG, "onCreate", null);
        setContentView(R.layout.main_activity);

        receiver = new BroadcastReceiver() {
			
			@Override
			public void onReceive(Context context, Intent intent) {
				// TODO Auto-generated method stub
				if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())){
					//处理接收到该广播时的逻辑事务
				}
			}
		};
        registerReceiver(receiver, new IntentFilter(Intent.ACTION_BOOT_COMPLETED));
    }
}
