Я работаю над Android-приложением, которое использует метеослужбу. В настоящее время я использую API с openweathermap.org, и я заметил, что в ответе есть также тег значка, и мне было интересно, как вы на самом деле получите этот образ для показа. Я пытался поиграть с ним, но я не могу понять это.OpenWeatherMap Icon загрузить android
Это мой Основная деятельность:
public class MainActivity extends Activity {
String description;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
protected void onStart() {
super.onStart();
Double lat = 55.676098;
Double lon = 12.568337;
String apiKey = "70c5bf4e84a725a8aeb3dd8c7df4c254";
String urlAPI = "http://api.openweathermap.org/data/2.5/weather?lat=" + lat + "&lon=" + lon + "&APPID=" + apiKey;
String imgURL = "http://openweathermap.org/img/w/" + description + ".png";
Weather weatherApi = new Weather();
weatherApi.execute(urlAPI);
weatherApi.execute(imgURL);
}
public void goToShowFishActivity(View view) {
Intent intent = new Intent(this, ShowFishiesActivity.class);
startActivity(intent);
}
public void goToAddNewCatchActivity(View view) {
Intent intent = new Intent(this, AddCatch.class);
startActivity(intent);
}
public void goToLogin(View view) {
Intent intent = new Intent(this, CreateUserActivity.class);
startActivity(intent);
}
private class Weather extends ReadHttpTask{
@Override
protected void onPostExecute(CharSequence charSequence){
String text = charSequence.toString();
Integer start = text.indexOf("icon\":\"") + "icon\":\"".length();
Integer end = text.indexOf("\"}",start);
description = text.substring(start, end);
TextView weatherTry = (TextView) findViewById(R.id.weatherTry);
weatherTry.setText(description);
}
}
}
Мой класс ReadHttpTask:
public class ReadHttpTask extends AsyncTask<String, Void, CharSequence> {
@RequiresApi(api = Build.VERSION_CODES.N)
@Override
protected CharSequence doInBackground(String...urls) {
String urlString = urls[0];
try{
CharSequence result = HttpHelper.GetHttpResponse(urlString);
return result;
}
catch (IOException ex){
cancel(true);
String errorMessage = ex.getMessage() + "\n" + urlString;
Log.e("Something went wrong", errorMessage);
return errorMessage;
}
}
}
И мой HttpHelper класс:
public class HttpHelper {
@RequiresApi(api = Build.VERSION_CODES.N)
public static CharSequence GetHttpResponse(String urlString) throws IOException {
URL url = new URL(urlString);
URLConnection connection = url.openConnection();
if (!(connection instanceof HttpURLConnection)) {
throw new IOException("Not an HTTP connection");
}
HttpURLConnection httpConnection = (HttpURLConnection) connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode != HttpURLConnection.HTTP_OK) {
String responseMessage = httpConnection.getResponseMessage();
throw new IOException("HTTP response code: " + responseCode + " " + responseMessage);
}
InputStream inputStream = httpConnection.getInputStream();
BufferedReader reader = null;
try {
reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
StringBuilder sb = new StringBuilder();
while (true) {
line = reader.readLine();
if (line == null) break;
sb.append(line);
}
return sb;
} finally {
if (reader != null) reader.close();
}
}
}
Спасибо! : DD Это работало как шарм! – kennyYice23
