快速簡單高德地圖接入
阿新 • • 發佈：2019-02-16
1.匯入SDK
連結：https://pan.baidu.com/s/1vdoPXmsZ4CuVfV_J144zuw 密碼：fvv2
裡面有定位 地圖 獲取螢幕中心經緯度 距離測量
用的是EventBus傳值
2.新增許可權
<!-- 用於訪問網路，網路定位需要上網 --> <uses-permission android:name="android.permission.INTERNET" /> <!-- 寫入擴充套件儲存，向擴充套件卡寫入資料，用於寫入快取定位資料 --> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <!-- 用於進行網路定位 --> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <!-- 獲取運營商資訊，用於支援提供運營商資訊相關的介面 --> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <!-- 用於訪問GPS定位 --> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <!-- 用於讀取手機當前的狀態 --> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <!-- 用於訪問wifi網路資訊，wifi資訊會用於進行網路定位 --> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <!-- 這個許可權用於獲取wifi的獲取許可權，wifi資訊會用來進行網路定位 --> <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /> <!-- 這個許可權用於允許程式在手機螢幕關閉後後臺程序仍然執行 --> <user-permission android:name="android.permission.WAKE_LOCK" />
3.加入你的application裡面
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="你的key" />
<service android:name="com.amap.api.location.APSService" />4.到EventBus包

這裡的包名只能是下面圖的包名
下面我在送大家一個查詢SHA1的方法直接在你的專案中執行得到返回值就行了
//獲取SHA1安全碼
public static String sHA1(Context context) {
try {
PackageInfo info = context.getPackageManager().getPackageInfo(
context.getPackageName(), PackageManager.GET_SIGNATURES);
byte[] cert = info.signatures[0].toByteArray();
MessageDigest md = MessageDigest.getInstance("SHA1");
byte[] publicKey = md.digest(cert);
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < publicKey.length; i++) {
String appendString = Integer.toHexString(0xFF & publicKey[i])
.toUpperCase(Locale.US);
if (appendString.length() == 1)
hexString.append("0");
hexString.append(appendString);
hexString.append(":");
}
String result = hexString.toString();
return result.substring(0, result.length()-1);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}直接在main函式中執行這個方法將返回值列印一下 複製到高德官網上就行了
