高德地圖，仿餓了麼確認收貨地址頁（簡易版）
先看一下效果 android
其實高德地圖示例中心已經有不少現成的demo了，能夠根據項目需求，下載demo自行查看git

高德地圖示例中心：lbs.amap.com/dev/demo數組
由於公司目前開發的項目，地圖模塊並非側重點，因此定位地址作得很簡易化。需求包括：定位當前位置，自動搜索周邊，搜索位置，選擇位置。下面會對代碼進行說明。安全
1.固然，首先得去高德地圖開放平臺中註冊帳號，建立應用bash
2.在app的build.gradle文件中引入地圖包，這邊我使用的是3d地圖，包括基礎地圖包、定位地圖包和搜索地圖包網絡
dependencies {
//高德地圖 3D地圖
implementation 'com.amap.api:location:latest.integration'
implementation 'com.amap.api:search:latest.integration'
implementation 'com.amap.api:3dmap:latest.integration'
}
複製代碼
3.在AndroidManifest.xml清單文件中，application裏面配置以下app
<!--高德地圖-->
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="申請應用的Key值"/>
複製代碼
接下來就能夠正式開發了ide
4.頂部的透明浮窗效果shape_map_top_bg.xml，定義一個漸變的透明度背景函數
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:gravity="center">
<shape>
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"/>
<gradient
android:angle="270"
android:startColor="#6C000000"
android:endColor="#00000000"
android:type="linear" />
</shape>
</item>
</layer-list>

5.定義Activity的佈局文件activity_map_layout1.xml，頂部的搜索框佈局layout_edit，後面我會在代碼中動態設置其高度
<?xml version="1.0" encoding="utf-8"?>

6.爲了防止地圖的搜索框，在觸發鍵盤後，由於高度不夠而被輸入法蓋住了，因此選擇動態控制底部搜索框的高度，代碼以下：
RelativeLayout.LayoutParams linearParams = (RelativeLayout.LayoutParams) bindingView.layoutBottom.getLayoutParams(); //取控件textView當前的佈局參數
int height = DensityUtil.getDisplayHeight() / 5 * 3;
linearParams.height = height;// 控件的高強制設成
bindingView.layoutBottom.setLayoutParams(linearParams); //使設置好的佈局參數應用到控件

8.顯示地圖的方式，請查看高德地圖官方說明 lbs.amap.com/api/android…
9.接下來我要說明的是我遇到的一種狀況：手機定位關閉後再次開啓，locationManager.getLastKnownLocation(provider)=null，我是這樣解決的：
首先，在oncreate初始化時，依然獲取最後一次定位的位置，並記下當前的最後一次位置lastLocation；
爲locationManager設置LocationListener監聽，包括GPS和NETWORK監聽；
一旦監聽到位置後，就會觸發onLocationChanged方法，這時候判斷lastLocation=null，就更新當前位置；
這樣就能夠解決位置關閉後開啓沒有辦法定位，又能防止搜索位置後，一直要定位到當前的這種狀況
好了，MapActivity的完整代碼以下：
