La valeur Edittext disparaît lors du défilement de recyclerview dans Android

Question

J'ai appelé recyclerview dans lequel mon arraylist est attaché avec l'adaptateur. Et quand l'adaptateur a son propre fichier de ligne dans lequel j'ai pris un texte d'édition et manuellement, je peux entrer le montant.

Mais le problème est que lorsque je fais défiler le recyclerview, la valeur du texte d'édition a disparu. Donc, ne peut pas voir les valeurs que je saisis.

classe Adaptateur

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; 

    /**

    */

Answer 1

i classe modèle créer un champ plus et défini comme vide sur la création d'objets, définissez pour modifier le texte dans onBindViewHolder(), sur la mise à jour du changement de texte objet trop ..

Solution: Utilisez ensuite le code ci-dessous à votre intérieur EditText tex méthode twatcher afterTextchange()

Code : yourEditTextName.setSelection(yourEditTextName.getText().length());
