Android通过广播接收者调用服务（service）内方法

摘要: Android通过广播接收者调用服务内方法 以及利用代码注册广播接收器（4大组件中唯一可以使用代码声明的组件（activity receiver provider service））

服务；

package com.pas.callmethod;

import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.widget.Toast;

public class MyService extends Service
{

private MyReciver receiver;

@Override
public void onCreate()
{
//采用代码方式注册广播接收者
receiver=new MyReciver();
IntentFilter filter=new IntentFilter();
filter.addAction("com.pas.call");
registerReceiver(receiver, filter);
super.onCreate();
}

@Override
public void onDestroy()
{
unregisterReceiver(receiver);
receiver=null;
super.onDestroy();
}
@Override
public IBinder onBind(Intent arg0)
{
return null;
}

private void method_inservice()
{
Toast.makeText(getApplicationContext(), "我的服务的方法……", Toast.LENGTH_SHORT).show();
}

private class MyReciver extends BroadcastReceiver
{

@Override
public void onReceive(Context arg0, Intent arg1)
{
System.out.println("内部接收者");
method_inservice();
}

}
}

活动:

package com.pas.callmethod;

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

public class MainActivity extends Activity
{

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

Intent intent=new Intent(this,MyService.class);
startService(intent);
}

@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 call(View v)
{
//发送自定义广播
Intent intent=new Intent();
intent.setAction("com.pas.call");
sendBroadcast(intent);
}
