Android入门逆引手册 - 10 列表框(ListView)的使用

这里介绍android.widget.ListView类的使用方法。 

 

 

 

 

 

 

 

 

● 设置Adapter，调用setAdapter()方法。
● 追加Item被点击时候的处理，调用setOnItemClickListener()方法。
● 追加Item被选择时候的处理，调用setOnItemSelectedListener()方法。

例程源码(Java)

01.ArrayAdapter<String> adapter = new ArrayAdapter<String>(

02.this,

03.android.R.layout.simple_list_item_1);

04. 

05.adapter.add("red");

06.adapter.add("green");

07.adapter.add("blue");

08. 

09.ListView listView = (ListView) findViewById(id.listView);

10. 

11.listView.setAdapter(adapter);

12. 

13.listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

14.@Override

15.public void onItemClick(

16.AdapterView<?> parent,

17.View view,

18.int position,

19.long id) {

20.ListView listView = (ListView) parent;

21.Log.v("Test", "id = " + id + "("

22.+ listView.getItemAtPosition(position).toString() + ")");

23.}

24.});

25. 

26.listView.setOnItemSelectedListener(new OnItemSelectedListener() {

27.@Override

28.public void onItemSelected(

29.AdapterView<?> parent,

30.View view,

31.int position,

32.long id) {

33.ListView listView = (ListView) parent;

34.Log.v("Test", "id = " + id + "("

35.+ listView.getSelectedItem().toString() + ")");

36.}

37.@Override

38.public void onNothingSelected(AdapterView<?> parent) {

39.}

40.});
