自定义信息窗口显示来自json android studio的重复数据

Question

我真的是Android编程的新手。

我可以问一个问题，为什么我的数据都一样。我从json获取数据并将其放在自定义信息窗口中，为什么它们都是重复的，但标记却不是。 对不起，我无法发送图片，因为我是第一次来这里提问

这是我的适配器类

适配器类

public class MarkerInfoWindowAdapter implements GoogleMap.InfoWindowAdapter {
private Context context;
private TextView tvnama, tvalamat, tvkursi, tvmeja, tvstop, tvlain, tvket;
public static String stonama, stoalamat, kursisto, mejasto, stopkontaksto, lainlainsto, keterangansto, id;
public MarkerInfoWindowAdapter(Context context){
    this.context = context.getApplicationContext();
}

@Override
public View getInfoWindow(Marker marker){
    return null;
}
@Override
public View getInfoContents(Marker marker){
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.map_marker_info_window, null);
    tvnama = (TextView) v.findViewById(R.id.tv_namasto);
    tvalamat = (TextView) v.findViewById(R.id.tv_alamatsto);
    tvkursi = (TextView) v.findViewById(R.id.tv_kursisto);
    tvmeja = (TextView) v.findViewById(R.id.tv_mejasto);
    tvstop = (TextView) v.findViewById(R.id.tv_stopkontaksto);
    tvlain = (TextView) v.findViewById(R.id.tv_lainlainsto);
    tvket = (TextView) v.findViewById(R.id.tv_keterangansto);
    tvnama.setText("Nama STO: "+stonama);
    tvalamat.setText("Alamat STO: "+stoalamat);
    tvkursi.setText("Fasilitas Kursi: "+kursisto);
    tvmeja.setText("Fasilitas Meja: "+mejasto);
    tvstop.setText("Fasilitas Stop Kontak: "+stopkontaksto);
    tvlain.setText("Fasilitas Lain Lain: "+lainlainsto);
    tvket.setText("Keterangan: "+keterangansto);
    return v;
}
}

MapsActivity``
