通过使用Adapter的getView()方法，实现ViewHolder模式。ViewHolder模式能够重复利用子视图，从而降低内存压力和CPU开销，进而优化显示效果。

以下是示例代码：

public class MyAdapter extends BaseAdapter {

private List mDataList;
private LayoutInflater mInflater;

public MyAdapter(Context context, List dataList) {
    mInflater = LayoutInflater.from(context);
    mDataList = dataList;
}

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

@Override
public Object getItem(int position) {
    return mDataList.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 = mInflater.inflate(R.layout.item_layout, parent, false);
        holder = new ViewHolder();
        holder.textView = (TextView) convertView.findViewById(R.id.tv_item);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    // 设置文本内容
    holder.textView.setText(mDataList.get(position));
    return convertView;
}

private static class ViewHolder {
    TextView textView;
}

}

在使用ListView时，将此适配器与ListView关联起来：

ListView listView = (ListView) findViewById(R.id.lv_list); MyAdapter adapter = new MyAdapter(this, dataList); listView.setAdapter(adapter);

注：dataList是数据源，可以从网络或本地文件中获取。
