高德地图实现

首先导入依赖

implementation 'com.amap.api:location:4.4.0'

还有权限

<!--用于进行网络定位-->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
    <!--用于访问GPS定位-->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
    <!--获取运营商信息，用于支持提供运营商信息相关的接口-->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
    <!--用于访问wifi网络信息，wifi信息会用于进行网络定位-->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
    <!--这个权限用于获取wifi的获取权限，wifi信息会用来进行网络定位-->
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
    <!--用于访问网络，网络定位需要上网-->
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
    <!--用于读取手机当前的状态-->
    <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>
    <!--写入扩展存储，向扩展卡写入数据，用于写入缓存定位数据-->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
    <!--用于申请调用A-GPS模块-->
    <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS"></uses-permission>
    <!--用于申请获取蓝牙信息进行室内定位-->
    <uses-permission android:name="android.permission.BLUETOOTH"></uses-permission>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

导入到清单文件中

<meta-data android:name="com.amap.api.v2.apikey" android:value="你的key">
        </meta-data>
        <service android:name="com.amap.api.location.APSService"></service>

布局文件

<LinearLayout xmlns:android="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"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/tv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="测试位置"
        android:gravity="center"/>

    <Button
        android:id="@+id/but_dianji"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="点击获取位置"/>

</LinearLayout>

方法实现

public class MainActivity extends AppCompatActivity {
    public AMapLocationClient mLocationClient = null;
    private TextView tv;
    private Button button;


    @Override
    protected void onCreate(Bundle savedInstanceState) {

        tv = (TextView) findViewById(R.id.tv);
        button = findViewById(R.id.but_dianji);
        initLocation();
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mLocationClient.startLocation();//可以写在点击事件中
            }
        });
        if(Build.VERSION.SDK_INT>=23) {
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(this, new String[]{
                        Manifest.permission.WRITE_EXTERNAL_STORAGE,
                        Manifest.permission.READ_EXTERNAL_STORAGE,
                        Manifest.permission.ACCESS_COARSE_LOCATION,
                        Manifest.permission.ACCESS_FINE_LOCATION,
                        Manifest.permission.READ_PHONE_STATE
                }, 100);
            }
        }

    }
    //36:EA:8F:23:28:F8:9F:50:7B:66:B2:4D:FF:13:05:F1:72:07:4B:3B
    private void initLocation(){
        //声明AMapLocationClient类对象
        //初始化定位
        mLocationClient = new AMapLocationClient(getApplicationContext());
        //异步获取定位结果
        AMapLocationListener mAMapLocationListener = new AMapLocationListener() {
            @Override
            public void onLocationChanged(AMapLocation amapLocation) {
                if (amapLocation != null) {
                    if (amapLocation.getErrorCode() == 0) {
                        //解析定位结果
                        tv.setText(amapLocation.getAddress());
                        mLocationClient.stopLocation();
                    }
                }
            }
        };
        //设置定位回调监听
        mLocationClient.setLocationListener(mAMapLocationListener);
        //启动定位

    }
}
