这篇文章主要为大家详细介绍了Android UI控件ExpandableListView基本用法,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
ExpandableListView介绍&
ExpandableListView的引入&
ExpandableListView可以显示一个视图垂直滚动显示两级列表中的条目，这不同于列表视图（ListView）。ExpandableListView允许有两个层次：一级列表中有二级列表。
&比如在手机设置中，对于分类，有很好的效果。手机版QQ也是这样的效果。
使用ExpandableListView的整体思路&
（1）给ExpandableListView设置适配器，那么必须先设置数据源。
&（2）数据源，就是此处的适配器类ExpandableAdapter，此方法继承了BaseExpandableListAdapter，需要重写里面的10个方法。
&数据源中，用到了自定义的View布局，此时根据自己的需求，来设置组和子项的布局样式。
&getChildView()和getGroupView()方法设置自定义布局。&
（3）数据源设置好，直接给ExpandableListView.setAdapter()即可实现此收缩功能。&
ExpandableListView的完整代码实现
&（1）activity_main.xml：在里面放置一个ExpandableListView控件&
&?xml version="1.0" encoding="utf-8"?&
&RelativeLayout
xmlns:android="/apk/res/android"
xmlns:tools="/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.smyhvae.expandablelistviewdemo.MainActivity"&
&ExpandableListView
android:id="@+id/expandableListView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
&/RelativeLayout&
（2）item_group.xml：一级列表的item的布局
&?xml version="1.0" encoding="utf-8"?&
&LinearLayout xmlns:android="/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#cccccc"
android:orientation="horizontal"&
android:id="@+id/tv_group"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:gravity="center"
android:text="group text"
android:textColor="#000000"
&/LinearLayout&
（3）item_child.xml：二级列表的item的布局
&?xml version="1.0" encoding="utf-8"?&
&LinearLayout xmlns:android="/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"&
&ImageView
android:id="@+id/iv_child"
android:layout_width="30dp"
android:layout_height="30dp"
android:src="@mipmap/ic_launcher"/&
android:id="@+id/tv_child"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="item text"
android:textColor="#000000"/&
&/LinearLayout&
（4）MainActivity.java：&
import android.app.A
import android.os.B
import android.util.L
import android.view.V
import android.view.ViewG
import android.widget.BaseExpandableListA
import android.widget.ExpandableListV
import android.widget.ImageV
import android.widget.TextV
public class MainActivity extends Activity {
private ExpandableListView expandableListV
//Model：定义的数据
private String[] groups = {"A", "B", "C"};
//注意，字符数组不要写成{{"A1,A2,A3,A4"}, {"B1,B2,B3,B4，B5"}, {"C1,C2,C3,C4"}}
private String[][] childs = {{"A1", "A2", "A3", "A4"}, {"A1", "A2", "A3", "B4"}, {"A1", "A2", "A3", "C4"}};
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
expandableListView = (ExpandableListView) findViewById(R.id.expandableListView);
expandableListView.setAdapter(new MyExpandableListView());
//为ExpandableListView自定义适配器
class MyExpandableListView extends BaseExpandableListAdapter {
//返回一级列表的个数
public int getGroupCount() {
return groups.
//返回每个二级列表的个数
public int getChildrenCount(int groupPosition) { //参数groupPosition表示第几个一级列表
Log.d("smyhvae", "--&" + groupPosition);
return childs[groupPosition].
//返回一级列表的单个item（返回的是对象）
public Object getGroup(int groupPosition) {
return groups[groupPosition];
//返回二级列表中的单个item（返回的是对象）
public Object getChild(int groupPosition, int childPosition) {
return childs[groupPosition][childPosition]; //不要误写成groups[groupPosition][childPosition]
public long getGroupId(int groupPosition) {
return groupP
public long getChildId(int groupPosition, int childPosition) {
return childP
//每个item的id是否是固定？一般为true
public boolean hasStableIds() {
//【重要】填充一级列表
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = getLayoutInflater().inflate(R.layout.item_group, null);
TextView tv_group = (TextView) convertView.findViewById(R.id.tv_group);
tv_group.setText(groups[groupPosition]);
return convertV
//【重要】填充二级列表
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = getLayoutInflater().inflate(R.layout.item_child, null);
ImageView iv_child = (ImageView) convertView.findViewById(R.id.iv_child);
TextView tv_child = (TextView) convertView.findViewById(R.id.tv_child);
//iv_child.setImageResource(resId);
tv_child.setText(childs[groupPosition][childPosition]);
return convertV
//二级列表中的item是否能够被选中？可以改为true
public boolean isChildSelectable(int groupPosition, int childPosition) {
注：请自行完成ConvertView和ViewHolder的优化。&
