android通信

android通讯

1、Activity之间通讯Intent（传参例子）
???? A端

Intent myintent=new Intent(aaactivity.this,bb.class);myintent.putExtra("myname","zhangmeie");startActivity(myintent);aaactivity.this.finish();

??? B端

Bundle bundle=this.getIntent().getExtras();if(null!=bundle){txt.setText(bundle.getString("myname").toString());}

2、本类Message+Handler通讯

for(i=0;i<a.length;i++){Thread.sleep(1000);if(i==4){Message m=new Message();m.what=Acitivy01.GUI_STOP_NOTIFIER;Acitivity01.this.myMessageHandler.sendMessage(m); //停止}else{Message m=new Message();m.what=Activity01.GUI_THREADING_NOTIFIER;Acitity01.this.myMessageHandler.sendMessage(m);//继续走}}

Handler myMessageHandler=new Handler(){public void handleMessage(Message msg){case Acitivity01.GUI_STOP_NOTIFIER:      m_progressBar.setVisibility(View.GONE);      ....................case Activity01.GUI_THREADING_NOTIFIER:     if(!Thread.currentThread().isInterrupted()){     .......................     }}}

3、应用程序之间通讯Broadcast

???? 程序A的activity01中

Intent intent = new Intent().setAction("com.a.acitity02").putExtra("title","hello");sendBroadcast(intent);  //广播出去

??? 程序B的AndroidManifest.xml加入注册

?

<receiver android:name="activity02">    <intent-filter android:priority="100">         <action android:name="com.a.actitity01"/>    </intent-filter></receiver>

??? 程序B的actitity02加入

public class activity02 extends BroadcastReceiver {            @Override            public void onReceive(Context context, Intent intent) {         if(intent.getAction().equals("com.a.actitity01")){         //播放一首音乐        MediaPlayer.create(context, R.raw.babayetu).start();        }    }}
