调用方式：

  //获取经纬度
        Location location = LocationUtils.getInstance(getApplicationContext()).showLocation();
        if (location != null) {
            String latitude = String.valueOf(location.getLatitude());
            String longitde = String.valueOf(location.getLongitude());
            Log.e("经度==========",latitude);
            Log.e("纬度==========",longitde);
            //根据经纬度获取地理位置
            String s = LocationUtils.getInstance(MainActivity.this).convertAddress(MainActivity.this, location.getLatitude(), location.getLongitude());
            mTv.setText("经度=========="+latitude+"\n"+"纬度=========="+longitde+"\n"+s);

需要添加的权限（六点零以上的系统需要动态获取）

Manifest.permission.INTERNET
Manifest.permission.ACCESS_COARSE_LOCATION
Manifest.permission.ACCESS_FINE_LOCATION
