高德地图集成步骤

一,下载sdk --代开2Dmap_Demo

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

三,导入jar包,并添加到依赖库(将2D地图demo的jar拷贝到项目)

四,拷贝Demo的清单文件

五,copy高德sdk的Demo的代码

六,地图页面的代码:

/**
 * 方法必须重写,关联生命周期,减少消耗,提高性能
 */
@Override
protected void onResume() {
    super.onResume();
    mBinding.mapView.onResume();
}

/**

 */
@Override
protected void onDestroy() {
    super.onDestroy();
    mBinding.mapView.onDestroy();
}

/**

@Override

            //2,只定位一次,就终止(为了提高性能)
            if (mlocationClient != null) {
                mlocationClient.stopLocation();
                mlocationClient.onDestroy();
            }
            //3,尝试搜索周边，搜索所有poi点，500米内
            doSearchQuery();
        } else {
            String errText = "定位失败," + amapLocation.getErrorCode() + ": " + amapLocation.getErrorInfo();
            Log.e("AmapErr", errText);
        }
    }
}

protected void doSearchQuery() {
    currentPage = 0;
    // 第一个参数表示搜索字符串，第二个参数表示poi搜索类型，第三个参数表示poi搜索区域（空字符串代表全国）
    query = new PoiSearch.Query(keyWord, "", city);
    query.setPageSize(50);// 设置每页最多返回多少条poiitem
    query.setPageNum(currentPage);// 设置查第一页

    if (lp != null) {

    }
}

public void onPoiSearched(PoiResult result, int rcode) {
    if (rcode == 1000) {

@Override
public void onPoiItemSearched(PoiItem poiItem, int i) {
}

public void onClick(View view) {
    switch (view.getId()) {
        case R.id.rl_exit:
            finish();
            if(Integer.valueOf(android.os.Build.VERSION.SDK)  >= 5) {
                overridePendingTransition(0,0);  //2个0表示activity切换不需要动画效果
            }
            break;
    }
}

}

七,适配器

public class AroundRvAdapter extends RecyclerView.Adapter {

private Context mContext;
public AroundRvAdapter(Context context) {
    mContext = context;
}
private List<PoiItem> mPoiItemList = new ArrayList<>();

public void setPoiItemList(List<PoiItem> 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

    <com.amap.api.maps2d.MapView
        android:id="@+id/map_view"
        android:layout_width="match_parent"
        android:layout_height="200dp">
    </com.amap.api.maps2d.MapView>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycle_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
    </android.support.v7.widget.RecyclerView>
</LinearLayout>

</layout>

九,适配器布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:padding="5dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">

<TextView
    android:padding="5dp"
    android:id="@+id/title"
    android:text="松日鼎盛"
    android:textSize="20sp"
    android:textColor="#000000"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

<TextView
    android:padding="5dp"
    android:id="@+id/address"
    android:textSize="16sp"
    android:textColor="#666666"
    android:text="深南大道"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>

</LinearLayout>
