一,下载sdk --代开2Dmap_Demo
image.png
image.png
二,获取appkey(先要获取keystore的shaw1值)
image.png
(1),在C:\Users\Administrator.android目录下找到debug.keystore,
(2,接着在该目录下的地址栏输入cmd命令
Keytool -v -list -keystore debug.keystore的绝对路径
(3,回车-->输入密码(密码是android)
(4,复制
image.png
三,导入jar包,并添加到依赖库(将2D地图demo的jar拷贝到项目)
image.png
四,拷贝Demo的清单文件
image.png
五,copy高德sdk的Demo的代码
image.png
六,地图页面的代码:
public class SecondLocationActivity extends AppCompatActivityimplements LocationSource, AMapLocationListener, PoiSearch.OnPoiSearchListener, View.OnClickListener {

// 注意设置合适的定位时间的间隔（最小间隔支持为2000ms），并且在合适时间调用stopLocation()方法来取消定位请求
// 在定位结束后，在合适的生命周期调用onDestroy()方法
// 在单次定位情况下，定位无论成功与否，都无需调用stopLocation()方法移除请求，定位sdk内部会移除
mlocationClient.startLocation();

七,适配器
public class AroundRvAdapter extends RecyclerView.Adapter {
private Context mContext;
public AroundRvAdapter(Context context) {
mContext = context;
}
private List mPoiItemList = new ArrayList<>();
public void setPoiItemList(List poiItemList) {
mPoiItemList = poiItemList;
notifyDataSetChanged();
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(mContext).inflate(R.layout.item_around, parent, false);
ViewHolder viewHolder = new ViewHolder(itemView);
return viewHolder;
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
ViewHolder viewHolder = (ViewHolder) holder;
viewHolder.setData(mPoiItemList.get(position));
}
@Override
public int getItemCount() {
if(mPoiItemList!=null){
return mPoiItemList.size();
}
return 0;
}
class ViewHolder extends RecyclerView.ViewHolder{
TextView mTitle;
TextView mAddress;
ViewHolder(View view) {
super(view);
mTitle = view.findViewById(R.id.title);
mAddress = view.findViewById(R.id.address);
}
public void setData(PoiItem poiItem) {
mTitle.setText(poiItem.getTitle());
mAddress.setText(poiItem.getSnippet()); //摘要信息
}
}
}
八,activity布局
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
九,适配器布局
android:padding="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
