如何在网格视图中显示微调器选择？

// 布局文件 grid_item_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/item_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Item" />

    <NumberPicker
        android:id="@+id/item_picker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

// Activity中的代码
public class MainActivity extends AppCompatActivity {

    private GridView gridView;

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

        gridView = findViewById(R.id.grid_view);
        gridView.setAdapter(new GridAdapter());
    }

    private class GridAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            return 9; // 假设有9个网格项
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if (convertView == null) {
                convertView = LayoutInflater.from(MainActivity.this).inflate(R.layout.grid_item_layout, parent, false);
            }

            TextView itemText = convertView.findViewById(R.id.item_text);
            NumberPicker itemPicker = convertView.findViewById(R.id.item_picker);

            itemText.setText("Item " + position);
            itemPicker.setMinValue(0);
            itemPicker.setMaxValue(100);
            itemPicker.setValue(50);

            itemPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
                @Override
                public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
                    // 处理微调器值变化的逻辑
                }
            });

            return convertView;
        }
    }
}
