实现

修改页面布局代码activity_main.xml，在页面上添加一个TextView来显示经纬度信息。

"1.0" encoding="utf-8"?>
"http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <TextView
        android:id="@+id/location"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:textStyle="bold" />

然后打开MainActivity.java,修改代码如下

package com.badao.servicetest;

import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;

import android.Manifest;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.WindowManager;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    private TextView text;  //定义用于显示LocationProvider的TextView组件

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);   //设置全屏显示

        text = (TextView) findViewById(R.id.location);  //获取显示Location信息的TextView组件
        //获取系统的LocationManager对象
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        //添加权限检查
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        //设置每一秒获取一次location信息
        locationManager.requestLocationUpdates(
                LocationManager.GPS_PROVIDER,      //GPS定位提供者
                1000,       //更新数据时间为1秒
                1,      //位置间隔为1米
                //位置监听器
                new LocationListener() {  //GPS定位信息发生改变时触发，用于更新位置信息

                    @Override
                    public void onLocationChanged(Location location) {
                        //GPS信息发生改变时，更新位置
                        locationUpdates(location);
                    }

                    @Override
                    //位置状态发生改变时触发
                    public void onStatusChanged(String provider, int status, Bundle extras) {
                    }

                    @Override
                    //定位提供者启动时触发
                    public void onProviderEnabled(String provider) {
                    }

                    @Override
                    //定位提供者关闭时触发
                    public void onProviderDisabled(String provider) {
                    }
                });
        //从GPS获取最新的定位信息
        Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
        locationUpdates(location);    //将最新的定位信息传递给创建的locationUpdates()方法中
    }

    public void locationUpdates(Location location) {  //获取指定的查询信息
        //如果location不为空时
        if (location != null) {
            StringBuilder stringBuilder = new StringBuilder();        //使用StringBuilder保存数据
            //获取经度、纬度、等属性值
            stringBuilder.append("您的位置信息：\n");
            stringBuilder.append("经度：");
            stringBuilder.append(location.getLongitude());
            stringBuilder.append("\n纬度：");
            stringBuilder.append(location.getLatitude());
//            stringBuilder.append("\n精确度：");
//            stringBuilder.append(location.getAccuracy());
//            stringBuilder.append("\n高度：");
//            stringBuilder.append(location.getAltitude());
//            stringBuilder.append("\n方向：");
//            stringBuilder.append(location.getBearing());
//            stringBuilder.append("\n速度：");
//            stringBuilder.append(location.getSpeed());
//            stringBuilder.append("\n时间：");
//            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH mm ss");    //设置日期时间格式
//            stringBuilder.append(dateFormat.format(new Date(location.getTime())));
            text.setText(stringBuilder);            //显示获取的信息
        } else {
            //否则输出空信息
            text.setText("没有获取到GPS信息");
        }
    }
}

 

最后打开AndroidMainfest.xml添加权限

    "android.permission.ACCESS_COARSE_LOCATION"/>
    "android.permission.ACCESS_FINE_LOCATION"/>

 

添加位置如下
