Issue
I want to show the data I got from json in my android project in the search layout section, but the data is not visible. Can you help me?
My Code:
public void searchView (View view){
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
SearchFragment searchFragment = new SearchFragment();
fragmentTransaction.replace(R.id.frameLayout, searchFragment).commit();
enterButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
city = cityAdd.getEditText().getText().toString().trim();
String url = "https://api.openweathermap.org/data/2.5/weather?q="+city+"&appid="+apikey;
RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null, new com.android.volley.Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
Log.d("Temperature",(url));
JSONObject temps = response.getJSONObject("main");
String temperatures = temps.getString("temp");
country.setText(city);
temp.setText(temperatures);
Intent intent = new Intent(MainActivity.this, SearchFragment.class);
intent.putExtra("city", country.getText().toString());
intent.putExtra("temp",temp.getText().toString());
startActivity(intent);
} catch (JSONException e) {
Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
}, new com.android.volley.Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(MainActivity.this, "Please check the city name", Toast.LENGTH_SHORT).show();
}
}
);
queue.add(request);
}
});
}

Hello, I want to show the data I got from json in my android project in the search layout section, but the data is not visible. Can you help me?
Solution
You are retrieving your data in your main activity and sending the data through your intent
intent.putExtra("city", country.getText().toString()); intent.putExtra("temp",temp.getText().toString());
However, you are not fetching the data that you sent through intent in your fragment. You have to fetch them according to the key values by which you sent. In your onCreateView() in your fragment, you can fetch each data you sent through your intent in the form:
String city = getArguments().getString("city");
