android - 文本输入布局 : RuntimeException - Failed to resolve attribute at index 24

Question

当我尝试在我的 textInputLayout 上 setErrorEnabled 时，我不断收到此错误:

这是场景 - 我在 popupwindow 中有一个 textInputLayout。这是popupwidow里面的代码。

public class NamePopUp extends PopupWindow {

    android.support.v7.widget.AppCompatEditText name;
    TextInputLayout nameInput;


    public NamePopUp(final Context context) {
        super(context);
        View popupView = LayoutInflater.from(context).inflate(R.layout.popup_rg_confirm, null);
        nameInput = (TextInputLayout) popupView.findViewById(R.id.name_input_layout);
    }
}

这是我的 popupwindow 布局的 xml:

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="12dp"
    android:theme="@style/TextLabel"
    app:backgroundTint="@color/white"
    app:rippleColor="@color/white"
    android:id="@+id/name_input_layout"
    android:layout_marginBottom="8dp"
    android:paddingRight="24dp"
    android:paddingLeft="24dp">

<android.support.v7.widget.AppCompatEditText
    android:id="@+id/enter_name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColor="@color/white"
    android:textCursorDrawable="@drawable/color_cursor"
    android:hint="@string/groupname"/>

</android.support.design.widget.TextInputLayout>

这是我正在使用的样式:

<style name="TextLabel" parent="TextAppearance.AppCompat">
    <!-- Hint color and label color in FALSE state -->
    <item name="android:textSize">20sp</item>
    <item name="android:textColorHint">@color/white</item>
    <!-- Label color in TRUE state and bar color FALSE and TRUE State -->
    <item name="colorAccent">@color/white</item>
    <item name="colorControlNormal">@color/white</item>
    <item name="colorControlActivated">@color/white</item>
</style>

弹出窗口在 android.support.v4.app.Fragment 内调用， fragment 在 AppCompatActivity 内。

当用户单击确定按钮但名称 edittext 为空白时，会出现此错误。换句话说，用户没有在edittext中输入任何内容并点击了ok:

    button_ok.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            if (StringUtils.isNotEmpty(name.getText().toString())) {
                nameInput.setErrorEnabled(false);
                groupNameEvent.doEvent(name.getText().toString());

            } else {
                nameInput.setErrorEnabled(true); //ERROR OCCURS HERE!
                nameInput.setError(context.getString(R.string.no_name));
            }
        }
    });

如何让这个错误消失？

只需将 TextLabel 的基本主题更改为 Widget.Design.TextInputLayout

<style name="TextLabel" parent="Widget.Design.TextInputLayout">
