    GridView gridView;

    String[] dizi = {
            "7", "8", "9", "C", "4", "5", "6", "/", "1", "2", "3", "*", "0", "=", "+", "-"
    };

    @Override
    protected void onCreate(javascript:void(0)Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gridView = (GridView) findViewById(R.id.gridView1);

        ArrayAdapter<String> adapter = new MyAdapter(this);
        adapter.addAll(dizi);//diziyi adaptöre gönderdik.
        gridView.setAdapter(adapter);//gridview ve adaptörü bağladık.
        adapter.notifyDataSetChanged();
    }

    private class MyAdapter extends ArrayAdapter<String> {//adaptörü sınıf olarak oluşturduk.

        MyAdapter(@NonNull Context context) {
            super(context, android.R.layout.simple_list_item_1);
        }

        @NonNull
        @Override
        public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {// pozisyonunu alır ve çizer
            if (convertView == null) {
                convertView = getLayoutInflater().inflate(R.layout.calc_button, parent, false);//VİEWVİ GÖRSEL HALE GETİRRİ INFLATER
            }

            TextView button = (TextView) convertView;
            button.setText(getItem(position));//pozisyonu alır.

            return button;
        }
    }
}
