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);
    }

}
