为什么EditText验证时会出现两个错误标志？(Why two error signs is visible when EditText validate?)

为什么EditText验证时会出现两个错误标志？(Why two error signs is visible when EditText validate?)

为了验证，我使用了saripaar验证库。 当表单无效时，它会给出带有消息的红色错误标志，但是当我单击错误字段时，另一个红色错误标志也会出现，这个额外的红色标志是意外的。 如何删除这个额外的错误标志？

For validation I have used saripaar validation library. When form is not valid it gives a red error sign with a message but when I click on error field another red error sign also appeared this extra red sign is unexpected. How can I remove this extra error sign?

最满意答案

查看instanceof AppCompatEditText并查看instanceof TextInputEditText都返回true 。 所以，它设置了两个错误图标。

您可以在onValidationFailed（）方法中更改条件，以避免出现这种情况。

if (view.getClass().getSimpleName().equalsIgnoreCase("AppCompatEditText")) { ((AppCompatEditText) view).setError(message); } else if (view.getClass().getSimpleName().equalsIgnoreCase("TextInputEditText")) { TextInputLayout textInputLayout = (TextInputLayout) view.getParent().getParent(); textInputLayout.setErrorEnabled(true); textInputLayout.setError(message); }

view instanceof AppCompatEditText and view instanceof TextInputEditText both return true. So, it's set two error icon.

You can change your conditions in onValidationFailed() method as bellow to avoid this scenario.

if (view.getClass().getSimpleName().equalsIgnoreCase("AppCompatEditText")) { ((AppCompatEditText) view).setError(message); } else if (view.getClass().getSimpleName().equalsIgnoreCase("TextInputEditText")) { TextInputLayout textInputLayout = (TextInputLayout) view.getParent().getParent(); textInputLayout.setErrorEnabled(true); textInputLayout.setError(message); }
