Android ListView实现单选及多选等功能示例
发布时间 - 2026-01-11 02:55:14 点击率：次本文实例讲述了Android ListView实现单选及多选等功能的方法。分享给大家供大家参考，具体如下：
在项目中也遇到过给ListView的item添加选择功能。比如一个网购APP，有个历史浏览页面，这个页面现点击item单选/多选及全选删除功能。
当时也是通过在数据中添加一个是否选择的字段来记录item的状态，然后根据这个字段有相应的position位置进行选择状态更改及删除操作。
刚刚看了Android API Demos中17种ListView的实现方法，发现ListView自身就带有我们所需要的单选，多选功能而且实现起来相当方便。
/**
* 单选或多选功能ListView
* @description：
* @author ldm
* @date 2016-4-21 上午10:44:37
*/
public class SingleChoiceList extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_single_choice, GENRES));
final ListView listView = getListView();
listView.setItemsCanFocus(false);
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);//添加这一句话，就实现单选功能
//listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);//添加这一句话，就实现多选功能
}
private static final String[] GENRES = new String[] {
"Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama",
"Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller"
};
}
/**
* 长按多选，添加了选择模式
* @description：
* @author ldm
* @date 2016-4-21 上午10:47:55
*/
public class ChoiceModeList extends ListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ListView lv = getListView();
lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
lv.setMultiChoiceModeListener(new ModeCallback());
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_checked, mStrings));
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
getActionBar().setSubtitle("Long press to start selection");
}
private class ModeCallback implements ListView.MultiChoiceModeListener {
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.list_select_menu, menu);
mode.setTitle("Select Items");
setSubtitle(mode);
return true;
}
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return true;
}
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.share:
Toast.makeText(ChoiceModeList.this, "Shared " + getListView().getCheckedItemCount() +
" items", Toast.LENGTH_SHORT).show();
mode.finish();
break;
default:
Toast.makeText(ChoiceModeList.this, "Clicked " + item.getTitle(),
Toast.LENGTH_SHORT).show();
break;
}
return true;
}
public void onDestroyActionMode(ActionMode mode) {
}
public void onItemCheckedStateChanged(ActionMode mode,
int position, long id, boolean checked) {
setSubtitle(mode);
}
private void setSubtitle(ActionMode mode) {
final int checkedCount = getListView().getCheckedItemCount();
switch (checkedCount) {
case 0:
mode.setSubtitle(null);
break;
case 1:
mode.setSubtitle("One item selected");
break;
default:
mode.setSubtitle("" + checkedCount + " items selected");
break;
}
}
}
private String[] mStrings = Cheeses.sCheeseStrings;
}
当我们通过以上这些方法实现ListView选中之后，我们可以把对应的item位置记录下来，就可以对相应地数据进行操作了
