You need to create a ArrayAdapter that links < in> string-array with Spinner .

The class ArrayAdapter has the static method createFromResource() that creates an adapter from a string-array .
Assign the adapter created to Spinner using the setAdapter () .

Change the chamarDialog() method this way:

private void chamarDialog() {

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    LayoutInflater inflater = getLayoutInflater();

    //Cria a view a ser utilizada no dialog
    ViewGroup view = (ViewGroup) inflater.inflate(R.layout.layout_newcheckin, null);

    //Obtém uma referencia ao Spinner
    Spinner spinner = (Spinner) view.findViewById(R.id.spinner_catogorias);

    //Cria o Adapter
    ArrayAdapter adapter = ArrayAdapter.createFromResource(this, R.array.categoria_array,
    android.R.layout.simple_spinner_dropdown_item);//ou android.R.layout.simple_spinner_item

    //Atribui o adapter ao spinner
    spinner.setAdapter(adapter);

    builder.setView(view);

    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "Cliked OK!", Toast.LENGTH_SHORT);
            return;
        }
    });
    builder.show();
}
