高德地圖集成步驟

一,下載sdk --代開2Dmap_Demo

二,獲取appkey(先要獲取keystore的shaw1值)

image.png

(1),在C:\Users\Administrator.android目錄下找到debug.keystore,

(2,接著在該目錄下的地址欄輸入cmd命令

Keytool -v -list -keystore debug.keystore的絕對路徑

(3,回車-->輸入密碼(密碼是android)

(4,復制

三,導入jar包,并添加到依賴庫(將2D地圖demo的jar拷貝到項目)

四,拷貝Demo的清單文件

五,copy高德sdk的Demo的代碼

六,地圖頁面的代碼:

            break;
    }
}

}

七,適配器

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

<layout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">

    <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,適配器布局

<?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>
