在AndroidManifest.xml文件中添加以下权限声明：

然后在代码中请求该权限：

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted, request it
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
            1);
} else {
    // Permission is already granted, proceed with your logic
    getLocation();
}

在你的Activity中添加以下方法，用于处理权限请求结果：

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
        @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == 1) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted, proceed with your logic
            getLocation();
        } else {
            // Permission denied, handle accordingly
            // For example, show a message or disable location-related functionality
        }
    }
}

确保在getLocation()方法中实现获取位置的逻辑。
