Here is screenshot ...my changes in spinner value reflects only after 2 swipes I have an app with 10 screens and i have 1 spinner in my main activity and a textbox in fragment .I want to display the recently selected spinner value in my textbox .

I wrote a code to display the selected spinner value in my text box and its become stable throughout all my screens.But i don't know how to dynamically change the text box value according to the recently selected spinner value. (Before downvoting kindly suggest me some solutions)

Here is code to get the spinner value 

String pos = (String) spinner.getSelectedItem();
        SharedPreferences sharedPref = getSharedPreferences("Mode", Activity.MODE_PRIVATE);
        SharedPreferences.Editor prefEditor = sharedPref.edit();
        prefEditor.putString("userChoicemode", pos);
        prefEditor.commit();

Here is the code to retrieve it

TextView modeselect = (TextView) view.findViewById(R.id.pass);

        SharedPreferences sharedPref = this.getActivity().getSharedPreferences("Mode", Activity.MODE_PRIVATE);
        String get = sharedPref.getString("userChoicemode",selected);

        modeselect.setText("" + get);

Try this

yourSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                    String selectedText = parent.getItemAtPosition(position).toString()

                    // Set your TextView here
                    myTextView.setText(selectedText);
                }

                @Override
                public void onNothingSelected(AdapterView<?> parent) {

                }
            });

And if your TextView is in different Fragment then follow this link Communication between Activity and Fragment

Call below method

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
       String text=spinner.getSelectedItem().toString();
       txtview.setText(text);
                    }
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

this above method calls when list set to your spinner and whenever user selects any item from spinner, you can get your spinner value from button click also by calling getSelectedItem() or if u want to get text only when user selects item from spinner you have to call this above override method

  • fragment having override method setUserVisiblehint it calls when a fragment visible to user call ur function in that method, Or make static variable in ur activity and pass it in your fragment by Activity.staticvariable – Shashwat Gupta Sep 11 '17 at 13:53
  • @Override public void setUserVisibleHint(boolean isVisibleToUser) { super.setUserVisibleHint(isVisibleToUser); if (isVisibleToUser) { //put your function here to set Text in fragment } } – Shashwat Gupta Sep 11 '17 at 14:01

You can call spinner's setOnItemSelectedListener

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {

                 modeselect.setText(spinner.getSelectedItem().toString());
                 //or 
                 //modeselect.setText(adapterView.getItemAtPosition(i));

                }

                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {

                }
            });
