android使用两种方式注册receiver

原文地址为： android使用两种方式注册receiver

1、

package com.example.myreceiver;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.content.IntentFilter;
import android.view.Menu;
import android.view.View;

public class MainActivity extends Activity {
private MyBroadcastReceiver receiver = new MyBroadcastReceiver();
private IntentFilter filter = new IntentFilter("com.feng.intent");
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}

public void start(View view){
Intent intent = new Intent("com.feng.intent");
intent.putExtra("name", "wang");
sendBroadcast(intent);
}

@Override
protected void onPause() {
super.onPause();
unregisterReceiver(receiver);
}

@Override
protected void onResume() {
super.onResume();
registerReceiver(receiver, filter);
}



}

package com.example.myreceiver;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.util.Log;public class MyBroadcastReceiver extends BroadcastReceiver{@Overridepublic void onReceive(Context arg0, Intent arg1) {System.out.println("good!i've recevied u!");Log.e("MyBroadcastReceiver", "good!i've recevied u!");}}

这种方式的好处是，使用灵活，可控性高。

另外一种是在mainfest.xml中注册。这种好处是只要应用程序安装后，就会一直处于监听状态。
