【中文标题】为啥 EditText 验证时会出现两个错误标志？【英文标题】：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？ 【发布时间】：2017-04-19 20:12:06 【问题描述】：对于验证，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，但是当我点击错误字段时，另一个红色错误标志也出现了，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？

【问题讨论】：
【参考方案1】：view instanceof AppCompatEditText 和 view instanceof TextInputEditText 都返回 true。所以，它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);
【讨论】：
很好的解释......很久以前我提出了这个问题并解决了......谢谢:)【参考方案2】：if(name.getText().toString().equalsIgnoreCase(""))
name.setError("请输入 Adda 的名称");
enter code here
