问题描述

列表视图中传递int值到string值

    TextView location=(TextView)template_view.findViewById(R.id.tvlocation);    TextView weather=(TextView)template_view.findViewById(R.id.tvweather);    TextView temp=(TextView)template_view.findViewById(R.id.tvtemp);    TextView dewpoint=(TextView)template_view.findViewById(R.id.tvdew);    TextView humidity=(TextView)template_view.findViewById(R.id.tvhumidity);    TextView windspeed=(TextView)template_view.findViewById(R.id.tvspeed);    TextView winddir=(TextView)template_view.findViewById(R.id.tvdir);    TextView windgust=(TextView)template_view.findViewById(R.id.tvgust);    TextView pressure=(TextView)template_view.findViewById(R.id.tvcondition);    TextView heatindex=(TextView)template_view.findViewById(R.id.tvheat);    TextView visibility=(TextView)template_view.findViewById(R.id.tvvisibility);    TextView precipitation=(TextView)template_view.findViewById(R.id.tvprecipitation);    TextView dailyprecipitation=(TextView)template_view.findViewById(R.id.tvdaily);    TextView sunrise=(TextView)template_view.findViewById(R.id.tvsunrise);    TextView sunset=(TextView)template_view.findViewById(R.id.tvsunset);    location.setText(Voicenames.get(position).getLocation());    weather.setText(Voicenames.get(position).getWeather());    //temp.setText(Voicenames.get(position).getTemp_c());    //dewpoint.setText(Voicenames.get(position).getDewpoint_c());    //windspeed.setText(Voicenames.get(position).getWind_kph());    //windgust.setText(Voicenames.get(position).getWind_gust_kph());    humidity.setText(Voicenames.get(position).getRelative_humidity());    winddir.setText(Voicenames.get(position).getWind_dir());    pressure.setText(Voicenames.get(position).getPressure_mb());    heatindex.setText(Voicenames.get(position).getHeat_index_c());    visibility.setText(Voicenames.get(position).getVisibility_km());    precipitation.setText(Voicenames.get(position).getPrecipitation());    dailyprecipitation.setText(Voicenames.get(position).getDaily_precipitation());    sunrise.setText(Voicenames.get(position).getSunrise());    sunset.setText(Voicenames.get(position).getSunset());

有一个全是string值的列表视图。我将注释放到int值中，然后将int值传递过去，但是总是报出空指针异常。应该怎么解决？

我用到JSONboject。

解决方案

我找到的实现方法：String.valueOf(Voicenames.get(position).getWhatever());
