Edittext-Wert verschwinden beim Scrollen Recyclerview in Android

Question

Ich habe Recyclerview aufgerufen, in dem meine Arraylist mit dem Adapter verbunden ist. Und wenn der Adapter eine eigene Zeilendatei hat, in der ich einen Bearbeitungstext eingegeben habe, kann ich manuell den Betrag eingeben.

Aber das Problem ist, wenn ich scroll die Recyclerview, Text bearbeiten Wert gegangen ist. So können die Werte nicht angezeigt werden, je nachdem, was von mir eingegeben wurde.

Adapter Klasse

public class AddSecondarySalesOrderProductDetailsAdapter extends RecyclerView.Adapter { 

    ArrayList<SecondarySalesProductDetailsModel> mArrSecondarySalesProductDetailsModel; 
    ArrayList<String> mArrProductQuantity; 
    private int mViewItem = 1; 
    private Activity mActivity; 
    private LayoutInflater mLayoutInflater; 
    ImageView mImageDeleteProduct; 
    private String mProductName, mProductAvaQuantity, mProductSKU, mOrderedQuantity; 

    /** 
    * Adapter contains the data to be displayed 
    */
