安卓横向列表HorizontalListView

 

首先是布局

<com.devsmart.android.ui.HorizontalListView
    android:id="@+id/listview_search_titlebar"
    android:layout_width="wrap_content"
    android:layout_height="20dp"
    android:layout_centerVertical="true"

    >

</com.devsmart.android.ui.HorizontalListView>



在activity里

private HorizontalListView listview_search_titlebar;

listview_search_titlebar = (HorizontalListView) findViewById(R.id.listview_search_titlebar);

listview_search_titlebar.setAdapter(new HorizontalListViewAdapter(shopanalysisInfo.getDatas()));//这里没有弄假数据的集合直接从接口获取的

下面是adapter

class HorizontalListViewAdapter extends BaseAdapter {

        private ShopanalysisInfo.DatasBean datas;

        public HorizontalListViewAdapter (ShopanalysisInfo.DatasBean datas) {

            this.datas = datas;
        }

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

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

        @Override
        public long getItemId(int position) {
            return 0;
        }
//        LayoutInflater inflater=LayoutInflater.from(FirstListView.this);

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder;
            if (convertView == null) {
                holder = new ViewHolder();
                convertView = View.inflate(this, R.layout.itemtext, null);
                holder.textView = (TextView) convertView.findViewById(R.id.textView);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }
            holder.textView.setText(datas.getKeywordList().get(position));
            return convertView;
        }

    }

public static class ViewHolder {
    private TextView textView;
}

整体来说就是listview的步骤。
