最近想做一个application实现当注册callback函数后数据更新，然后将更新得数据显示到listview上
从log信息上看 在实现callback后会更新三组数据，数据不是同一时间发送得，可能存在几百毫秒周期性
第一组 01-02 00:01:04.920 I/MainActivity( 5832): receive Data:0a 09 00 00
第二组 01-02 00:01:05.150 I/MainActivity( 5832): receive Data:0b 0a 02 02 02 37 37 bf 60 01 2d 01 f0 81 00 00 27 20 08 12 01 00 00 00 00 00 01 01 23 08

第三组 01-02 00:01:05.160 I/MainActivity( 5832): receive Data:52 0b 00 01 02
可是当显示到listview上的时候只有两组，我同样试验了很多组都存在数据不全的情况，还请各位大神帮忙看看是何种原因造成的，万分感谢。
如下是我写的部分代码，供参照：
实现Runnable来完成listview的显示
private final Runnable task2 = new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
handler.post(this);
update_num++;
setContentView(R.layout.listview);
