我正在开发一个项目，一旦创建了片段，就需要更改textview的文本。值将来自我的数据库。我能够获取值但我不能将它传递给我的TextViews。我应该使用什么方法？我在try-catch中尝试了public class MostlyBorrowedBookLayout extends Fragment {
private Button popup;
private PopupWindow popupWindow;
LayoutInflater layoutInflater;
private RelativeLayout relativeLayout;
View myView;
SessionManager session;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
myView = inflater.inflate(R.layout.botd_layout, container, false);
popup = (Button) myView.findViewById(R.id.btnpopup);
session = new SessionManager(getActivity().getApplicationContext());
final TextView txtTitle= (TextView) myView.findViewById(R.id.txtTitle);
final TextView txtAuthor= (TextView) myView.findViewById(R.id.txtAuthor);
final TextView txtPublisher= (TextView) myView.findViewById(R.id.txtPublisher);
final TextView txtRate = (TextView) myView.findViewById(R.id.txtRate);
final TextView txtAvailability = (TextView) myView.findViewById(R.id.txtAvailability);
final TextView txtBookLevel = (TextView) myView.findViewById(R.id.txtBookLexile);
//ERROR HOW CAN I CALL THE VALUE FROM onResponse
txtTitle.setText(bookTitle);
txtAuthor.setText(bookAuthor);
txtBookLevel.setText(bookLevel);
txtPublisher.setText(bookPublisher);
txtAvailability.setText(availability_name);
// convertToString
HashMap<String, Integer> user_int = session.getUserLexileNID();
Integer lexile = user_int.get(SessionManager.KEY_LEXILE);
//final TextView
final TextView testing = (TextView) myView.findViewById(R.id.txtBookLexile);
relativeLayout = (RelativeLayout) myView.findViewById(R.id.relative);
final int userLexile = Integer.parseInt(lexile.toString());
Response.Listener<String> responseListener = new Response.Listener<String>() {
@Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
boolean success = jsonResponse.getBoolean("success");
if (success) {
String bookTitle = jsonResponse.getString("BookTitle");
String bookAuthor = jsonResponse.getString("BookAuthor");
String bookPublisher = jsonResponse.getString("BookPublisher");
int bookLevel = jsonResponse.getInt("bookLevel");
int availability_name = jsonResponse.getInt("availability_name");
//tried having the setText here but wont work
}else{
Toast.makeText(getActivity(),"Mostly Borrowed Book Error", Toast.LENGTH_SHORT);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
MostlyBorrowedBookRequest mostlyBorrowedBookRequest = new MostlyBorrowedBookRequest(userLexile,responseListener);
RequestQueue queue = Volley.newRequestQueue(getActivity());
queue.add(mostlyBorrowedBookRequest);
popup.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PopUpCommentRate dialog = new PopUpCommentRate();
dialog.show(getActivity().getFragmentManager(), "my_dialog");
}
});
return myView;
}
，但它没有用。我非常抱歉。我只是个新手。
