Android 给ListView设置Adapter

Adapter：

class MyAdapter extends BaseAdapter {
        private List<Person> personList;

        public MyAdapter(List<Person> personList) {
            this.personList = personList;
        }

        @Override
        public int getCount() {
            return personList.size();
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        /**
         * 使用打气筒
         */
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            Person person  = personList.get(position);
            View view = View.inflate(MainActivity.this, R.layout.list_view, null);
            //在view里面查找
            TextView idTextView = (TextView) view.findViewById(R.id.id);
            //一定要是String类型
            idTextView.setText("ID："+person.getId()+"");

            TextView nameTextView = (TextView) view.findViewById(R.id.name);
            nameTextView.setText(person.getName());

            TextView ageTextView = (TextView) view.findViewById(R.id.age);
            ageTextView.setText(person.getAge()+"");
            return view;
        }
