Comment coder ce type de conception d'écran de mot de passe, alors qu'après la saisie du mot de passe, les cercles devraient changer ou ImageView devrait changer .. ??

Utilisez LolliPin
Une bibliothèque de code secret Android de conception matérielle. Prend en charge les empreintes digitales.
<com.github.orangegangsters.lollipin.lib.views.PinCodeRoundView
Android:id="@+id/pin_code_round_view"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:layout_marginTop="@dimen/pin_code_round_top_margin"
Android:layout_marginBottom="@dimen/pin_code_elements_margin"
app:lp_empty_pin_dot="@drawable/pin_empty_dot"
app:lp_full_pin_dot="@drawable/pin_full_dot"/>
En utilisant ce code dans TextWatcher:
@Override
public void afterTextChanged(Editable s) {
switch (s.length()) {
case 4:
i4.setImageResource(R.drawable.circle2);
break;
case 3:
i4.setImageResource(R.drawable.circle);
i3.setImageResource(R.drawable.circle2);
break;
case 2:
i3.setImageResource(R.drawable.circle);
i2.setImageResource(R.drawable.circle2);
break;
case 1:
i2.setImageResource(R.drawable.circle);
i1.setImageResource(R.drawable.circle2);
break;
default:
i1.setImageResource(R.drawable.circle);
}
}
Quand j'ai ajouté la sucette dans mon projet, j'ai eu quelques erreurs.
Ensuite, j'ai trouvé d'autres liraires géniaux aussi.
Vérifiez ces:
Rappelez-vous qu'il s'agit de vues afin qu'elles soient un peu plus personnalisables ... Bon codage :)
