android - Android EditText错误消息未显示在底部

Question

我有一个表单，用户可以在其中输入客户信息。当我尝试验证字段时，我使用了editText.setError(errorMessage)，它显示了错误消息，但是它显示在我的EditText的顶部，这使用户感到困惑。如下图所示。



关于如何解决此问题的任何想法？

XML上的EditText

<LinearLayout

<Spinner
    android:id="@+id/sp_estados"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"/>

<Spinner
    android:id="@+id/sp_cidade"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:prompt="@string/cliente_cidade"/>

此ClienteEditActivity包含两个具有不同形式的片段，因此我在片段上听操作菜单的单击，单击菜单时，我用它来调用may验证:

if (!isValidEmail(etEmail)) {
     cancel = true;
     focusView = etEmail;
}
//after other validations
if (cancel){
   focusView.reqeustFocus();
} else {
   //save datas
}

isValidEmail方法是这样的:

protected boolean isValidEmail(EditText editText) {

  validate = new Validate(editText);

  validate.addValidador(new ValidadorVazio(getContext()));
  validate.addValidador(new ValidadorEmail(getContext()));

  return validate.isValid();
}

我的 Validate类如下所示:

public class Validate{
   private EditText etFonte;

   public Validate(EditText etFonte){
      this.etFonte = etFonte;
   }

   public void addValidador(AbstractValidador validador){
      lalidadores.add(validador);
   }

   public boolean isValid(){
      for (AbstractValidador validator : lValidadores) {
         try {
            if (!validator.isValid(etFonte.getText().toString())) {
               if(errorNotification != null) {
                  errorNotification.onInvalid(this);
               } else {
                  setSourceViewError(validator.getMessage(), validator.getErrorDrawable());
               }
               return false;
            } else {
               if(errorNotification != null) errorNotification.onValid(this);
            }
         } catch (ValidadorException e) {
            e.printStackTrace();
            if(errorNotification != null) {
               errorNotification.onInvalid(this);
            } else {
               setSourceViewError(e.getMessage(),validator.getErrorDrawable());
            }
            return false;
         }
      }
      etFonte.setError(null);
      return true;
   }

   private void setSourceViewError(String errorMessage, Drawable errorDrawable) {
      if(errorDrawable != null) {
         etFonte.setError(errorMessage, errorDrawable);
      } else {
        etFonte.setError(errorMessage);
      }
   }
}

在TextInputLayout而不是EditText上设置错误，这是您的代码...

<android.support.design.widget.TextInputLayout
  android:id="@+id/textInputLayout"
  android:layout_width="match_parent"
  android:layout_height="wrap_content">

  <EditText
    android:id="@+id/et_nome"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/cliente_nome"
    android:imeActionId="@+id/cli_name"
    android:imeActionLabel="@string/str_next"
    android:imeOptions="actionUnspecified"
    android:inputType="textPersonName"
    android:maxLines="1"
    android:singleLine="true"/>

在运行时获取TextInputLayout并应用以下代码...

TextInputLayout textInputLayout = (TextInputLayout) findVeiwById(R.id.textInputLayout);
textInputLayout.setErrorEnabled(true);
textInputLayout.setError("Please enter a valid license number");

它将产生类似这样的输出...
