android 嵌套的listview示例(可参考实现朋友圈评论)
最近在项目中用到listview中再嵌套一个listview，两层也有监听，都没有问题。其实，主要解决里面那一层的listview的高度计算就可以，外面那一层listview自动计算。加上里面那层展开的，就是高度。这种解决方案经常应用于朋友圈的评论。每一条说说，然后下面有评论。

1、项目结构图
2、实现效果图
这上面效果图的监听两层都有，以及外面的button都可以。够多样化吧。
3、ChildListView
package com.nest.view;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.ListView;
public class ChildListView extends ListView {
public ChildListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
// TODO Auto-generated constructor stub
}
public ChildListView(Context context, AttributeSet attrs) {
super(context, attrs);
// TODO Auto-generated constructor stub
}
public ChildListView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
}
}
里面listview的高度的计算。
4、外面那层listview的适配器ParentAdapt
package com.nest.adapt;
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
import com.nest.activity.R;
import com.nest.base.BaseObjectListAdapter;
import com.nest.entity.Entity;
import com.nest.entity.ShowEntity;
/**
* 父listview适配器
* @author mmsx
*
*/
public class ParentAdapt extends BaseObjectListAdapter{
private ArrayList mChildList;
public static int mParentItem = -1;
public static boolean mbShowChild = false;
public ParentAdapt(Context context, List extends Entity> datas) {
super(context, datas);
initData();
}
private void initData() {
mChildList = new ArrayList();
mChildList.clear();
for (int i = 0; i < 5; i++) {
ShowEntity tempEntity = new ShowEntity("字标题" + String.valueOf(i), "内容");
mChildList.add(tempEntity);
}
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vHolder = null;
if (convertView == null) {
vHolder = new ViewHolder();
convertView = mInflater.inflate(R.layout.activity_main_list_item, null);
vHolder.textViewTitle = (TextView)convertView.findViewById(R.id.textView_1);
vHolder.textViewContent= (TextView)convertView.findViewById(R.id.textView_2);
vHolder.listViewItem = (ListView)convertView.findViewById(R.id.listView_child);
vHolder.buttonStake = (Button)convertView.findViewById(R.id.button_1);
convertView.setTag(vHolder);
}else {
vHolder = (ViewHolder) convertView.getTag();
}
ShowEntity tempEntity = (ShowEntity) mDatas.get(position);
vHolder.textViewTitle.setText(tempEntity.getTitle());
vHolder.textViewContent.setText(tempEntity.getContent());
//点击那个弹出那个，如果已经弹出就收回子listview
if (mParentItem == position && mbShowChild) {
//子listview实在这里加载数据的
ChildAdapt tempAdapt = new ChildAdapt(mContext, mChildList);
vHolder.listViewItem.setAdapter(tempAdapt);
vHolder.listViewItem.setVisibility(View.VISIBLE);
//子listview的点击监听
vHolder.listViewItem.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView> parent, View view,
int position, long id) {
Toast.makeText(mContext, "Child Listview" + String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
}else {
vHolder.listViewItem.setVisibility(View.GONE);
}
vHolder.buttonStake.setOnClickListener(new ParentButtonLisener());
//记住是那个button事件
vHolder.buttonStake.setTag(position);
return convertView;
}
class ViewHolder{
TextView textViewTitle;
TextView textViewContent;
ListView listViewItem;
Button buttonStake;
}
//父listview的button的监听
private class ParentButtonLisener implements OnClickListener{
@Override
public void onClick(View v) {
Integer nPosition = (Integer) (v.getTag());
Toast.makeText(mContext, "提示" + String.valueOf(nPosition.intValue()), Toast.LENGTH_SHORT).show();
}
}
}
5、里面那层listview的适配器ChildAdapt
package com.nest.adapt;
import java.util.List;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import com.nest.activity.R;
import com.nest.base.BaseObjectListAdapter;
import com.nest.entity.Entity;
import com.nest.entity.ShowEntity;
/**
* 子listview适配器
* @author mmsx
*
*/
public class ChildAdapt extends BaseObjectListAdapter{
public ChildAdapt(Context context, List extends Entity> datas) {
super(context, datas);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder vHolder = null;
if (convertView == null) {
vHolder = new ViewHolder();
convertView = mInflater.inflate(R.layout.activity_main_list_item_1, null);
vHolder.textViewTitle = (TextView)convertView.findViewById(R.id.textView_1);
vHolder.textViewContent= (TextView)convertView.findViewById(R.id.textView_2);
convertView.setTag(vHolder);
}else {
vHolder = (ViewHolder) convertView.getTag();
}
ShowEntity tempEntity = (ShowEntity) mDatas.get(position);
vHolder.textViewTitle.setText(tempEntity.getTitle());
vHolder.textViewContent.setText(tempEntity.getContent());
return convertView;
}
class ViewHolder{
TextView textViewTitle;
TextView textViewContent;
}
}
6、实现调用MainActivity
package com.nest.activity;
import java.util.ArrayList;
import com.nest.adapt.ParentAdapt;
import com.nest.entity.ShowEntity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.app.Activity;
/**
* listview嵌套listview实现效果
* @author mmsx
*
*/
public class MainActivity extends Activity {
private ParentAdapt mParentAdapt;
private ArrayList mParentList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initData();
initView();
}
private void initData() {
mParentList = new ArrayList();
mParentList.clear();
for (int i = 0; i < 20; i++) {
ShowEntity tempEntity = new ShowEntity("标题" + String.valueOf(i), "内容");
mParentList.add(tempEntity);
}
}
private void initView() {
ListView listView = (ListView)findViewById(R.id.listView1);
mParentAdapt = new ParentAdapt(this, mParentList);
listView.setAdapter(mParentAdapt);
listView.setOnItemClickListener(new AdaptItemClick());
//长按listview就不写示范了
//listView.setOnItemLongClickListener(listener);
}
//父listview的单击事件的监听
private class AdaptItemClick implements OnItemClickListener{
@Override
public void onItemClick(AdapterView> parent, View view, int position,
long id) {
if (ParentAdapt.mParentItem == position && ParentAdapt.mbShowChild) {
ParentAdapt.mbShowChild = false;
}else {
ParentAdapt.mbShowChild = true;
}
ParentAdapt.mParentItem = position;
mParentAdapt.notifyDataSetChanged();
}
}
}
布局就不贴，有好几个。有需要下载项目源码。
