2.xml 4aty

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.louis.classifymenuview.MainActivity">    <LinearLayout        android:layout_width="wrap_content"        android:layout_height="wrap_content">        <ListView            android:id="@+id/classify_mainlist"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_weight="20"            android:background="#fff"            android:cacheColorHint="#00000000"            android:divider="#fff"            android:dividerHeight="1px"            android:fastScrollEnabled="true"            android:listSelector="#00000000"            android:scrollbars="none" />        <ListView            android:id="@+id/classify_morelist"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_weight="17"            android:background="#fff"            android:cacheColorHint="#00000000"            android:divider="#ffebebeb"            android:dividerHeight="0.5px"            android:fastScrollEnabled="true"            android:listSelector="#00000000"            android:scrollbars="none" />    LinearLayout>LinearLayout>

3.简陋的item xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"><TextView    android:id="@+id/id_tv_list_item"    android:layout_width="match_parent"    android:gravity="center_vertical"    android:padding="10dp"    android:layout_height="match_parent" />LinearLayout>

4.main adpter MainListBaseAdapter

package com.louis.classifymenuview;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import java.util.List;import java.util.Map;/** * Created by Administrator on 2016/3/17. */public class MainListBaseAdapter extends BaseAdapter {    Context context;    List> mainMapList;    public int getNowSelectedIndex() {        return nowSelectedIndex;    }    public void setNowSelectedIndex(int nowSelectedIndex) {        this.nowSelectedIndex = nowSelectedIndex;        this.notifyDataSetChanged();//及时通知显示    }    private int nowSelectedIndex = 0;    public MainListBaseAdapter(Context context, List> mainMapList) {        this.context = context;        this.mainMapList=mainMapList;    }    @Override    public int getCount() {        return mainMapList.size();    }    @Override    public Object getItem(int position) {        return mainMapList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        if (convertView==null){            convertView= LayoutInflater.from(context).inflate(R.layout.list_items,null);        }        TextView tv_list_item= (TextView) convertView.findViewById(R.id.id_tv_list_item);        tv_list_item.setText(mainMapList.get(position).get("mainName").toString());        if (position==nowSelectedIndex){            tv_list_item.setBackgroundColor(0xFFFFFFFF);        }else        {            tv_list_item.setBackgroundColor(0xFFEBEBEB);        }        return convertView;    }}

5。 more list adapter

package com.louis.classifymenuview;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.TextView;import java.util.List;import java.util.Map;/** * Created by Administrator on 2016/3/17. */public class MoreListBaseAdpter extends BaseAdapter {    Context context;    List> moreMapList;    private int nowSelectedIndex = 0;    public MoreListBaseAdpter(Context context, List> moreMapList) {        this.context = context;        this.moreMapList = moreMapList;    }    @Override    public int getCount() {        return moreMapList.size();    }    @Override    public Object getItem(int position) {        return moreMapList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        if (convertView == null) {            convertView = LayoutInflater.from(context).inflate(R.layout.list_items, null);        }        TextView tv_list_item = (TextView) convertView.findViewById(R.id.id_tv_list_item);        tv_list_item.setText(moreMapList.get(position).get("moreName").toString());        if (position == nowSelectedIndex) {            tv_list_item.setTextColor(0xFFB3EE3A);        } else {            tv_list_item.setTextColor(0xFF525252);        }        return  convertView;    }    public int getNowSelectedIndex() {        return nowSelectedIndex;    }    public void setNowSelectedIndex(int nowSelectedIndex) {        this.nowSelectedIndex = nowSelectedIndex;        this.notifyDataSetChanged();//及时通知显示    }}
