Android Studio – When the spinner item is selected, I want the button text to be the selected spinner item. or can we just do it in string.xml?

MainActivity.java

Spinner spinner = (Spinner) findViewById(R.id.spinner);

    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
            R.array.Door_array, android.R.layout.simple_spinner_item);

    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

    Button button = (Button)findViewById(R.id.Button1);
    button.setText(spinner.getSelectedItem().toString());

}

}

    Changing the text of button every time you must enter your code inside of this functions :

    String spinner_text = "";
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parentView, View 
selectedItemView, 
int position, long id) {
        spinner_text = parent.getItemAtPosition(position).toString();
        yourButton.settext(spinner_text);//Set text to button

    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // Set a default text on button
    }
});
