I have weather app, which is get weather information json from here:
http://icomms.ru/inf/meteo.php/?tid=44
There's a minus in "temp"
value (for ex. : "temp":"−16"
), and when I get value from json with retrofit2 and show it in textview it shows −16
instead of -16
How I can show -16
instead of −16
?
Fragment from RecyclerViewAdapter (I use it to show weather info for multiply days), where I set text to textview
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
Meteo meteo = data.get(position);
holder.date.setText(meteo.date);
holder.tod.setText(meteo.tod);
holder.pressure.setText(meteo.pressure);
// THIS IS TEMPERATURE SETTING TEXT LINE
holder.temp.setText(meteo.temp);
holder.humidity.setText(meteo.humidity);
holder.wind.setText(meteo.wind);
holder.cloud.setText(meteo.cloud);
}
Weather data class:
public class Meteo {
public String date;
public String tod;
public String pressure;
public String temp;
public String humidity;
public String wind;
public String cloud;
}
Response body:
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(APIService.HOST)
.addConverterFactory(GsonConverterFactory
.create())
.build();
APIService apiService = retrofit.create(APIService.class);
Call<List<Meteo>> call = apiService.getMeteo(44);
call.enqueue(new Callback<List<Meteo>>() {
@Override
public void onResponse(Call<List<Meteo>> call, Response<List<Meteo>> response) {
MeteoAdapter adapter = new MeteoAdapter(response.body());
// Method show just shows list of weather data
getViewState().show(adapter);
}
@Override
public void onFailure(Call<List<Meteo>> call, Throwable t) {
Log.d("MyLog", "WRONG");
}
});

Try this. I use it for formatting html tags in a textview:
String s = Html.fromHtml("−16");
tv.setText(s);
Reasoning: It sets the text as a Spanned object, rather than a string.
Note: Cannot test this currently, sorry if it doesnt work.
