我为自己的BaseAdapter自定义ListView,其中实现了AdapterView.OnItemClickListener

问题是onItemClick(AdapterView<?>, View, int, long)方法从不被调用。我想我需要在主interface中而不是在Activity自定义适配器中实现该ListView

MyListViewAdapter.java:

public class MyListViewAdapter extends BaseAdapter implements AdapterView.OnItemClickListener
{
    private Context context;
    private ArrayList<MyListViewRow> rowsList = new ArrayList<MyListViewRow>(); // All one row items

    private TextView a;


    public MyListViewAdapter(Context context,ArrayList<MyListViewRow> rowsList)
    {
        this.context = context;
        this.rowsList = rowsList;
    }

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

    @Override
    public Object getItem(int position)
    {
        return this.rowsList.get(position);
    }

    @Override
    public long getItemId(int position)
    {
        return position;
    }

    /**
     * Returns a new row to display in the list view.
     *
     * Position - position of the current row.
     *
     */
    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        LayoutInflater layoutInflater = (LayoutInflater) this.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        /**
         * Inflating the root view and all his children and set them to a View Object.
         *
         */
        View row = layoutInflater.inflate(R.layout.list_view_row,null);

        // Get all the views in my row
        this.a = (TextView) row.findViewById(R.id.a_id;


        MyListViewRow myListViewRow = rowsList.get(position);

        // Set values to all the views in my row
        this.a.setText(myListViewRow.getA());



        return row;
    }


    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id)
    {
        Toast.makeText(context, "onItemClick LV Adapter called", Toast.LENGTH_LONG).show();

    }


} // End of MyListViewAdapter class


我对吗?

最佳答案

为什么在适配器内会有一个OnItemClickListener?您可能在Adapter内有OnClickListener,或者最佳做法是将OnItemClickListener设置为ListView或在活动/片段中使用的任何AdapterView。
您目前的操作方式因以下几个原因而无法使用:


您没有将侦听器设置为视图。
您不能将OnItemClickListener设置为TextView。
在适配器类内部将onClickListener设置为TextView,意味着您将必须单击TextView本身,否则,将不会调用侦听器。

关于java - 从不调用BaseAdapter OnItemClickListener,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/36814378/
