如何在ListView中按比例拉伸列及其标题

public class CustomAdapter extends BaseAdapter {
    private List<List<String>> data;

    public CustomAdapter(List<List<String>> data) {
        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 holder;
        if (convertView == null) {
            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
            holder = new ViewHolder();
            holder.column1 = convertView.findViewById(R.id.column1);
            holder.column2 = convertView.findViewById(R.id.column2);
            holder.column3 = convertView.findViewById(R.id.column3);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        List<String> rowData = data.get(position);
        holder.column1.setText(rowData.get(0));
        holder.column2.setText(rowData.get(1));
        holder.column3.setText(rowData.get(2));

        return convertView;
    }

    private static class ViewHolder {
        TextView column1;
        TextView column2;
        TextView column3;
    }
}

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/column1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Column 1" />

    <TextView
        android:id="@+id/column2"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="2"
        android:text="Column 2" />

    <TextView
        android:id="@+id/column3"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="3"
        android:text="Column 3" />

</LinearLayout>

ListView listView = findViewById(R.id.listView);
CustomAdapter adapter = new CustomAdapter(data);
listView.setAdapter(adapter);
