如何使用ArrayAdapter我在arraylist中有数据并使用listView

Question

如何使用ArrayAdapter我在arraylist中有数据并使用listView？

//String s = var_arrayList.get(3).getTitle().toString();//var_arrayList <= arrayList
    //R.layout.list_last_topic //<= listViwe have TextView - TextView - ImageView
    adapter = new new_topicAdapter(getApplicationContext(), R.layout.list_last_topic, new_topicList);

我应该在班级{new_topicAdapter}内写什么？
