Answer 1

For me the problem is that I was using getApplicationContext(). When I replace getApplicationContext() with this it works fine.

ArrayAdapter<*> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, documentsCategories);

Else, try to store it on selecting the item:

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> adapter, View v,
                    int position, long id) {
                // On selecting a spinner item
                String item = adapter.getItemAtPosition(position).toString();

                // Showing selected spinner item
                Toast.makeText(getApplicationContext(),
                        "Selected Country : " + item, Toast.LENGTH_LONG).show();
            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        });

Answer 4

This answer may be a little stupid but try it. It worked for me.

1. Check the background color of your spinner!
2. And if it`s white change it
3. Enjoy it!

Answer 5

Problem:

Spinner displays neither the default nor selected item value. But drop-down menu items are show when selected.

Cause:

Background and text color both being white!!!

Solutions:

xml(Preferable):

Write a custom layout for a spiner item and use it instead of the default,android.R.layout.simple_spinner_item.

How to change spinner text size and text color?

Code(Less reliable):

your_spinner_instance.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){
    public void onItemSelected(AdapterView<?> parent, View view, int pos,
                               long id) {
        ((TextView) view).setTextColor(Color.RED);
    }
    public void onNothingSelected(AdapterView<?> parent) {
    }

});

Android needs some major update or maybe dart and flutter should take over...

Answer 6

if you have a custom adapter you should change the TextView text color

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    TextView view = (TextView) super.getView(position, convertView, parent);
    view.setTextColor(Color.parseColor("#000000"));
    return view;
}

and if you don't have a custom adapter you should just change spinner background
