android实现消息提醒，拨打电话功能

1.消息提醒功能：

public class NotifyTest {public  static final int ID=1;private List<Homework>list;private Context context;private HomeworkDto dto;public NotifyTest(Context context,List<Homework> list) {super();this.list = list;this.context=context;}public void addNotificaction() {          NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);          // 创建一个Notification          Notification notification = new Notification();          notification.icon = R.drawable.notify;// 设置显示在手机最上边的状态栏的图标          notification.tickerText = "亲，你有信息啦~~~";  // 当前的notification被放到状态栏上的时候，提示内容                 notification.defaults=Notification.DEFAULT_SOUND;// 添加声音提示          notification.audioStreamType= android.media.AudioManager.ADJUST_LOWER;//audioStreamType的值必须AudioManager中的值，代表着响铃的模式                  Intent intent = new Intent(context, HomeworkActivity.class);//从一个activity跳到另外一个activity          Bundle mBundle = new Bundle();        dto=new HomeworkDto(list);mBundle.putSerializable("homework", dto);intent.putExtras(mBundle);        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_ONE_SHOT);          // 点击状态栏的图标出现的提示信息设置          notification.setLatestEventInfo(context, "通知：", "你最近有"+list.size()+"个作业要交，点击查看", pendingIntent);        manager.notify(ID, notification);     }  

2.拨打电话功能：

listView.setOnItemClickListener(new OnItemClickListener() {//监听点击事件@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1,int arg2, long arg3) {// TODO Auto-generated method stub String string_phoneNum =numberList.get(arg2).getNumber();//得到电话号码                 Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+string_phoneNum));//调用系统拨打电话服务        startActivity(intent);//}});
