android - Android 中的 InputTextLayout setError() 方法不起作用

Question

我设计了一个包含自定义 Edittext 的自定义 InputTextLayout。此自定义 Edittext 扩展了“AppCompatEdittext”。我的 MainActivity 也扩展了 AppCompatActivity。但我仍然无法使用 TextInputLayout 显示错误消息。以下是我来自各种文件的代码 fragment 。

主.xml

<android.support.design.widget.TextInputLayout
            android:id="@+id/last_name_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/first_name_layout"
            android:layout_marginLeft="25dp"
            android:layout_marginRight="25dp"
            android:layout_marginTop="12dp"
            android:background="@drawable/grey_button_normal"
            android:hint="Last name"
            android:minHeight="48dp"
            android:paddingTop="3dp"
            android:theme="@style/TextLabel">

            <com.feebite.widgets.StyleableEditText
                android:id="@+id/lastname_edittext"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true"
                android:layout_gravity="center_vertical"
                android:background="@android:color/transparent"
                android:gravity="center_vertical"
                android:minHeight="48dp"
                android:nextFocusDown="@+id/email_edittext"
                android:paddingBottom="10dp"
                android:paddingLeft="15dp"
                android:singleLine="true"
                android:textColor="@color/darkish_grey"
                android:textColorHint="@color/darkish_grey"
                android:textCursorDrawable="@null"
                android:textSize="18sp" />

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

主 Activity .java

mLastNameLayout = (TextInputLayout) findViewById(R.id.last_name_layout);
 mLastNameLayout.setHint("Last name");
mLastNameLayout.setErrorEnabled(true);

来自 styles.xml 的自定义主题

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

并显示错误。

Answer 1

也尝试设置以下属性:

<item name="android:textColorHighlight">@color/Your color</item>
<item name="android:textColorLink">@color/Your color</item>
