如何在java中使用带有基本适配器android的网格视图创建3/2网格

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:numColumns="3"
    android:columnWidth="100dp"
    android:stretchMode="columnWidth"
    android:horizontalSpacing="10dp"
    android:verticalSpacing="10dp"/>

public class MainActivity extends AppCompatActivity {
    private GridView gridView;
    private GridAdapter gridAdapter;
    private List<String> gridData;

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

        gridView = findViewById(R.id.gridView);
        gridData = new ArrayList<>();
        // 添加要显示的网格项数据
        gridData.add("Item 1");
        gridData.add("Item 2");
        gridData.add("Item 3");
        gridData.add("Item 4");
        gridData.add("Item 5");
        gridData.add("Item 6");

        gridAdapter = new GridAdapter(this, gridData);
        gridView.setAdapter(gridAdapter);
    }
}

public class GridAdapter extends BaseAdapter {
    private Context context;
    private List<String> data;

    public GridAdapter(Context context, List<String> data) {
        this.context = context;
        this.data = data;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null) {
            convertView = LayoutInflater.from(context).inflate(R.layout.grid_item, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(R.id.textView);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        String item = data.get(position);
        viewHolder.textView.setText(item);

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

<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/textView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:padding="10dp"/>

</LinearLayout>
