1.效果图

2.先导入jar包，可以去官网下载如图：

特别注意：其中地图和定位还有TabLayout在前面详细说过,这里就不重复了(所以复制全部会报错~)

}

2.2.这里用了封装的万能适配器，也可以继承BaseAdapter以前博文也写过

import android.content.Context;
import android.graphics.Color;
import android.widget.TextView;
import com.amap.api.services.core.PoiItem;
import com.helloworld.demo.R;
import com.helloworld.demo.adapter.commonlist.CommonAdapter;
import com.helloworld.demo.adapter.commonlist.ViewHolder;
import com.helloworld.demo.util.Tools;
import java.util.List;public class MyAdapter extends CommonAdapter<PoiItem> {private int selectedPosition = -1;public MyAdapter(Context context, List<PoiItem> datas) {super(context, R.layout.adapter_item, datas);}public void setSelectedPosition(int position) {selectedPosition = position;}@Overrideprotected void convert(ViewHolder holder, PoiItem poiItem, int position) {//名称String name = poiItem.getTitle();TextView locationName = holder.getView(R.id.location_name);locationName.setText(Tools.isEmpty(name) ? "-" : name);//距离int distance = poiItem.getDistance();//街道String snippet = poiItem.getSnippet();TextView locationInfo = holder.getView(R.id.location_info);locationInfo.setText(distance + "m | " + snippet);if (selectedPosition == position) {locationName.setTextColor(Color.parseColor("#1296db"));locationInfo.setTextColor(Color.parseColor("#1296db"));} else {locationName.setTextColor(Color.parseColor("#444444"));locationInfo.setTextColor(Color.parseColor("#999999"));}}
}

2.3.MapDemoActivity对应的布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="match_parent"android:background="#fff"android:orientation="vertical"><com.amap.api.maps.MapView
        android:id="@+id/map"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="4.5"/><android.support.design.widget.TabLayout
        android:id="@+id/tablayout"android:layout_width="match_parent"android:layout_height="wrap_content"android:layout_gravity="bottom"android:background="#f1f1f1"app:layout_collapseMode="pin"app:tabIndicatorColor="@color/colorAccent"app:tabIndicatorHeight="2dp"app:tabMode="scrollable"app:tabPadding="5dp"app:tabSelectedTextColor="@color/colorAccent"app:tabTextColor="#444444"/><ListView

2.4.MyAdapter对应的布局文件

<?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="wrap_content"android:gravity="center_vertical"android:orientation="horizontal"android:padding="10dp"><LinearLayout
        android:layout_width="0dp"android:layout_height="wrap_content"android:layout_marginRight="15dp"android:layout_weight="8.2"android:orientation="vertical"><TextView
            android:id="@+id/location_name"android:layout_width="wrap_content"android:layout_height="wrap_content"android:ellipsize="end"android:maxLines="1"android:text="-"android:textColor="#444444"android:textSize="15sp"/><TextView
