定義LocationManager對象實現監聽接口

獲取到維度 經度 使用GetAddressUtil工具類得到位置信息

根據經緯度獲取當前位置地址信息工具類

package com.example.myapplication;
import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.os.Build;
import android.util.Log;

import androidx.annotation.RequiresApi;

import java.util.List;

public class GetAddressUtil {
Context context;
public GetAddressUtil(Context context) {
this.context = context;
}
@RequiresApi(api = Build.VERSION_CODES.GINGERBREAD)
public String getAddress(double lnt, double lat) {
Geocoder geocoder = new Geocoder(context);
boolean falg = geocoder.isPresent();
StringBuilder stringBuilder = new StringBuilder();
try {
//根據經緯度獲取地理位置信息—這裏會獲取最近的幾組地址信息，具體幾組由最後一個參數決定
List

addresses = geocoder.getFromLocation(lat, lnt, 1);
if (addresses.size() > 0) {
Address address = addresses.get(0);
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
//每一組地址裏面還會有許多地址。這裏我取的前2個地址。xxx街道-xxx位置
if (i == 0) {
stringBuilder.append(address.getAddressLine(i)).append("-");
}
if (i == 1) {
stringBuilder.append(address.getAddressLine(i));
break;
}
}
stringBuilder.append(address.getAdminArea());//省份
stringBuilder.append(address.getLocality());//市
stringBuilder.append(address.getFeatureName());//周邊地址
Log.d(“wy”, “地址信息—>” + stringBuilder);
}
} catch (Exception e) {
e.printStackTrace();
}
return stringBuilder.toString();
}
