TextInputLayout: RuntimeException - Failed to resolve attribute at index 24

问题

I keep on getting this error when I try to setErrorEnabled on my textInputLayout :

This is the scenario - I have a textInputLayout inside a popupwindow. This is the code inside the popupwidow.

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);
    }
}

This is my xml for the popupwindow layout:

<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>

This is the style I'm using:

<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>

The popupwindow is called inside a android.support.v4.app.Fragment and the fragment is inside a AppCompatActivity.

The error occurs here when the user clicks the ok button but the name edittext is blank. In other words, the user has not entered anything in the edittext and have clicked 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));
            }
        }
    });

How do I get this error to disappear?

回答1:

Just change the base theme for TextLabel to Widget.Design.TextInputLayout

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

回答2:

For me a following works (https://stackoverflow.com/a/42779409/2914140):

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="textColorError">@color/design_textinput_error_color_light</item>
</style>
