Question

我已经在sqlite中实现了一个有一个表的数据库。我已经编写了数据retreival方法。但是在我检索了一个列并将其存储在游标中之后，如何在列表视图或列表活动中显示该列< / p>

Answer 1

试试这个示例代码：

获取ArrayList中的列数据：

ArrayList<String> data = new ArrayList<String>();
data= // get your column data here

然后设置Array Adapter类：

public class ListArrayAdapter extends ArrayAdapter<String> {

    private Context context;
    private ArrayList<String> list;
    private ListView listView;

    public GalleryListArrayAdapter(Context context, ArrayList<String> list, ListView listView) {
        super(context, R.layout.fragment_list_item, list);

        this.context = context;
        this.list = list;
        this.listView = listView;

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        final int pos = position;

        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View rowView = inflater.inflate(R.layout.fragment_list_item, parent, false);
        return rowView; 
    }
}

在listview中显示光标列
