我想要带有垂直滚动的horizo​​ntalListview。早些时候我尝试使用 Listview 中的 Horizo​​ntalscrollview 来实现它。它适用于静态编号。的数据项。但就我而言,它们是动态的。所以我从这里下载了Horizo ​​ntalListView 的库(代码)

现在我将 Horizo​​ntalListViewDemo 活动设为片段并在另一个活动中调用它。我的目标是在带有垂直滚动视图的活动中多次调用它。但我尝试了 1 个片段和应用程序崩溃。LogCat 在 Horizo​​ntalListViewDemo 片段的 Layoutinflator 中显示错误。

Horizo​​ntalListViewDemo

public class HorizontalListViewDemo extends Fragment{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View view = inflater.inflate(R.layout.listviewdemo, container, false);
        HorizontalListView listview = (HorizontalListView)view.findViewById(R.id.listview);
        listview.setAdapter(mAdapter);
        return view;



    }

    /* @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.listviewdemo);

        HorizontalListView listview = (HorizontalListView) findViewById(R.id.listview);
        listview.setAdapter(mAdapter);

    }*/



    private static String[] dataObjects = new String[]{ "Text #1",
        "Text #2",
        "Text #3",
        "Text #4" }; 

    private BaseAdapter mAdapter = new BaseAdapter() {

        private OnClickListener mOnButtonClicked = new OnClickListener() {

            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(), "clicked",Toast.LENGTH_LONG).show();
                /*
                AlertDialog.Builder builder = new AlertDialog.Builder(HorizontalListViewDemo.this);
                builder.setMessage("hello from " + v);
                builder.setPositiveButton("Cool", null);
                builder.show();*/

            }
        };

        @Override
        public int getCount() {
            return dataObjects.length;
        }

        @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) {
            View retval = LayoutInflater.from(parent.getContext()).inflate(R.layout.viewitem, null);
            TextView title = (TextView) retval.findViewById(R.id.title);
            Button button = (Button) retval.findViewById(R.id.clickbutton);
            button.setOnClickListener(mOnButtonClicked);
            title.setText(dataObjects[position]);

            return retval;
        }

    };

}

任何帮助,将不胜感激。

title.setText(dataObjects[位置]); << 我猜它应该是一个'字符串'
