Change

  id.setText(obj.getId()); 

with

  id.setText(String.valueOf(obj.getId()));    

if you pass an int as argument for a TextView android will look for a String with id the int you provide. If it does not found throws an exception

一个重要的一点是你应该使用Activity.onCreate()method 代替Activity.onStart().
