我想知道如何从Recycler View适配器获取编辑文本的位置.我使用Card View,其中水平线性布局有三个视图TextView,EditText视图和TextView.我想从Recycler View Adapter中的Textwatcher获取特定的EditText位置.

适配器:

public class CartlistAdapter extends RecyclerView.Adapter < CartlistAdapter.ViewHolder > {

    private ArrayList < CartItemoriginal > cartlistadp;
    private ArrayList < Cartitemoringinaltwo > cartlistadp2;
    DisplayImageOptions options;
    private Context context;
    public static final String MyPREFERENCES = "MyPrefs";
    public static final String MYCARTPREFERENCE = "CartPrefs";
    public static final String MyCartQtyPreference = "Cartatyid";
    SharedPreferences.Editor editor;
    SharedPreferences shared,
    wishshared;
    SharedPreferences.Editor editors;
    String pos,
    qtyDelete;
    String date;
    String currentDateandTime;
    private static final int VIEW_TYPE_ONE = 1;
    private static final int VIEW_TYPE_TWO = …

我不知道如何解决这个问题.它在许多活动中显示相同的错误.怎么解决？

提前致谢.
