Android之仿美团和百度外卖选址控件

一：效果图

二：实现步骤

1.选址控件xml布局实现

<?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"
    android:background="#ffffff"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="2">

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

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:layout_gravity="center"
            android:src="@mipmap/gps_position"
            android:translationY="-18dp" />
    </RelativeLayout>


    <ListView
        android:id="@+id/map_list"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="3"
        android:background="#ffffff"
        android:divider="#ffffff"
        android:dividerHeight="0.5dp"
        android:scrollbars="none"></ListView>
</LinearLayout>

2.选址控件Activity实现(代码都有注释就不多说了)

            setResult(RESULT_OK, intent);
            finish();
        }
    }

}

3.导入第三方jar包和so文件并引用

4.去高德官方申请应用KEY在AndroidManifest.xml的Application下申明

5.在AndroidManifest.xml给相应的权限

<!--高德权限-->
<!--地图包、搜索包需要的基础权限-->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!--定位包、导航包需要的额外权限（注：基础权限也需要）-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_CONFIGURATION" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
