Android 下拉列表选值初级实例，通过血型选择来练习下拉框的使用。 　　super.onCreate(savedInstanceState); 　　setContentView(R.layout.main); 　　m_TextView = (TextView) findViewById(R.id.TextView1); 　　m_Spinner = (Spinner) findViewById(R.id.Spinner1); 　　//将可选内容与ArrayAdapter连接 　　adapter = new ArrayAdapter(this, android.R.layout.simple_spinner_item, m_Countries); 　　//设置下拉列表的风格 　　adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 　　//将adapter添加到m_Spinner中 　　m_Spinner.setAdapter(adapter); 　　//添加Spinner事件监听 　　m_Spinner.setOnItemSelectedListener(new Spinner.OnItemSelectedListener() { 　　 @Override 　　 public void onItemSelected(AdapterView arg0, View arg1, int arg2, long arg3) 　　 { 　　 m_TextView.setText("你的血型是：" + m_Countries[arg2]); 　　 //设置显示当前选择的项 　　 arg0.setVisibility(View.VISIBLE); 　　 } 　　});

Android 创建备忘录的例子，可自定义备忘录内容，自定义时间和自定义提醒闹钟的类型、铃声等。相关代码： 　　c.setTimeInMillis(System.currentTimeMillis());//设置当前时间 　　c.set(Calendar.HOUR_OF_DAY, hourOfDay);//设置小时 　　c.set(Calendar.MINUTE, minute);//设置分钟 　　c.set(Calendar.SECOND, 0);//设置秒 　　c.set(Calendar.MILLISECOND, 0);//设置毫秒 　　Intent intent=new Intent(Sample6_12_Activity.this,AlarmReceiver.class);//运行AlarmReceiver类 　　PendingIntent pi=PendingIntent.getBroadcast(//创建PendingIntent对象 　　Sample6_12_Activity.this, 0, intent, 0); 　　AlarmManager alarm=(AlarmManager)Sample6_12_Activity.this.getSystemService(ALARM_SERVICE); 　　alarm.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pi);//设置闹钟提醒一次 　　alarm.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), 120000, pi);//每两分钟提醒一次 　　String tempHour=(hourOfDay+"").length()>1?hourOfDay+"":"0"+hourOfDay; 　　String tempMinute=(minute+"").length()>1?minute+"":"0"+minute;

非常适合初学者的android程序，开源的，只需解压到myworkplace里就可以了，android环境自己可以配置。(I think that it is good for you )

我偷懒就用java写了个简单的服务器，大家明白原理就好。 服务端共开放两个端口，一个udp上行端口用来接收amr音频流，另一个tcp下行端口用来发送amr音频流。 我这里写的服务端实现了组播的功能，即一个人在录音，可以同时让很多人同时听到。 简而言之，服务端做的唯一一件事情就是转发音频流，
