为什么EditText验证时会出现两个错误标志？

Question

为了验证，我使用了 saripaar 验证库。当表单无效时，它会给出一个带有消息的红色错误标志，但是当我单击错误字段时，还会出现另一个红色错误标志，这个额外的红色标志是意外的。我怎样才能删除这个额外的错误标志？

Answer 1

view instanceof AppCompatEditText 和 view instanceof TextInputEditText 都 return true。所以，设置了两个错误图标。

您可以如下更改 onValidationFailed() 方法中的条件以避免这种情况。

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);
}

Answer 2

if(name.getText().toString().equalsIgnoreCase("")){ name.setError("请输入阿达的姓名"); }enter code here
