高德地图的快速接入

1.导入SDK

链接：https://pan.baidu.com/s/1vdoPXmsZ4CuVfV_J144zuw 密码：fvv2

里面有定位地图获取屏幕中心经纬度距离测量

用的是EventBus传值

2.添加权限


<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

<user-permission android:name="android.permission.WAKE_LOCK" />

3.加入你的application里面

<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

implementation 'de.greenrobot:eventbus:3.0.0-beta1'

android:text="bb"
android:onClick="bb"/>
</LinearLayout>

9.如果你写到这里运行没有实现定位成功的话一定要注意你的包名

这里的包名只能是下面图的包名

下面我在送大家一个查询SHA1的方法直接在你的项目中运行得到返回值就行了

//获取SHA1安全码
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函数中运行这个方法将返回值打印一下复制到高德官网上就行了
