该应用的界面如下，界面代码在此不再给出，源码github账户下载

MainActivity.java

 public class MainActivity extends Activity {
     private TextView tvTitle;
     private TextView tvContent;
     private Button btnSend;
     private String title;
     private String content;

     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         tvTitle=(TextView) findViewById(R.id.editText1);
         tvContent=(TextView) findViewById(R.id.EditText01);
         btnSend=(Button) findViewById(R.id.btnSend);

         btnSend.setOnClickListener(new OnClickListener(){

             @Override
             public void onClick(View v) {
                 // TODO Auto-generated method stub
                 send();
             }
         });

     }
     public void send(){
         title=tvTitle.getText().toString();//标题
         content=tvContent.getText().toString();//内容

         //1.得到NotificationManager服务
         NotificationManager nm=(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
         //2.实例化一个通知，指定图标、概要、时间
         Notification n = new Notification(R.drawable.ic_launcher,"通知",System.currentTimeMillis());
         //3.指定通知的标题、内容和intent
         Intent intent = new Intent(this, MainActivity.class);
         PendingIntent pi= PendingIntent.getActivity(this, 0, intent, 0);
         n.setLatestEventInfo(this, title, content, pi);
         //指定声音
         //n.defaults = Notification.DEFAULT_SOUND;
         //4.发送通知
         nm.notify(1, n);
     }

 }

点击“发送”按钮，即可在通知栏显示发送的消息!
