public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView info = (TextView)findViewById(R.id.info);

        Field[] fieldDrawables = android.R.drawable.class.getFields();
        for(int i=0; i<fieldDrawables.length; i++){
            Field field = fieldDrawables[i];
            info.append("R.drawable." + field.getName() + " :\n");
            info.append(field.toString() + "\n");

            try {
                int value = (int) field.get(fieldDrawables);
                info.append("value = " + value + "\n");
            } catch (IllegalAccessException e) {
                e.printStackTrace();
