可以通过自定义适配器来实现在ListView行的末尾添加文本的功能。以下是一个示例：

首先，创建一个自定义的适配器类，继承自BaseAdapter：

public class CustomListAdapter extends BaseAdapter {
    private Context mContext;
    private List mData;

    public CustomListAdapter(Context context, List data) {
        mContext = context;
        mData = data;
    }

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

    @Override
    public Object getItem(int position) {
        return mData.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(mContext).inflate(android.R.layout.simple_list_item_1, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(android.R.id.text1);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        String item = (String) getItem(position);
        viewHolder.textView.setText(item + " - Appended Text");

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

接下来，在Activity中使用这个自定义的适配器来显示ListView：

public class MainActivity extends AppCompatActivity {
    private ListView mListView;
    private CustomListAdapter mAdapter;

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

        List data = new ArrayList<>();
        data.add("Item 1");
        data.add("Item 2");
        data.add("Item 3");

        mListView = findViewById(R.id.listView);
        mAdapter = new CustomListAdapter(this, data);
        mListView.setAdapter(mAdapter);
    }
}

最后，在activity_main.xml布局文件中添加一个ListView控件：

这样，每个ListView行的末尾都会添加一个" - Appended Text"的文本。
