Android BroadcastReciecer 两种接收方式

1.在Manifest中，静态注册，和Activity同等级，在application中

<receiver android:name=".MyReceiver">
    <intent-filter>
        <action android:name="android.intent.action.AIRPLANE_MODE"></action>
    </intent-filter>
</receiver>      

2.在Java代码里，动态注册，一般在Activity的onCreate方法里

package com.alan.broadcast1;

import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

/**
 * Created by CanxinQiu on 2016/9/1.
 * Description: Broadcast lesson, register receiver in Java code
 *
 */
public class MainActivity extends AppCompatActivity {
    private MyReceiver myReceiver;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        IntentFilter filter = new IntentFilter();
        filter.addAction("android.intent.action.AIRPLANE_MODE");
        myReceiver = new MyReceiver();
        registerReceiver(myReceiver,filter);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        unregisterReceiver(myReceiver);
    }
}
      
   

3.两种注册方式的区别

(1).静态注册后不需要程序启动就可以接收广播，只要app装进去就有效果

(2).动态注册只有app启动后才可以接收广播
