Material design Spinner using TextInputLayout.OutlinedBox styling

Question

I am currently using Material Design TextInputLayout OutlinedBox as shown below:

Answer 1

From the other answers, "AutoCompleteTextView" is the answer but it does not do the same as a spinner does.

Here is my solution. Just put normal edittext inside TextInputLayout and make this editText disabled for inputs. And put a 0dp,0dp spinner for normal spinner working.

Don't make spinner visibility=gone, because if it's gone, spinner listener does not work

layout.xml

java code

set click listener to edittext for trigger spinner click

findViewById(R.id.editText).setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
    
                    spinner.performClick();
                }
            });

in spinner listener, set edittext text from selected item,

  spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView parent, View view, int position, long id) {

                selectedCity= (City) parent.getAdapter().getItem(position);

                editText.setText(selectedCity.getScreenText());

                RDALogger.debug("selectedObject " + selectedCity);
            }

            @Override
            public void onNothingSelected(AdapterView parent) {

            }
        });

and the result view
