.XML

<android.support.design.widget.TextInputLayout
android:id="@+id/tilname"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/TextLabel"
app:errorTextAppearance="@style/error_appearance">
<EditText
android:id="@+id/edname"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:hint="@string/full_name"
android:textColorHint="@color/gray"
android:textColor="@color/white"
android:textSize="@dimen/_15sdp"
android:inputType="" />
</android.support.design.widget.TextInputLayout>

.JAVA

if (edName.getText().toString().trim().isEmpty()) {
tilName.setError(getResources().getString(R.string.err_msg_name));
requestFocus(edName);
return false;
} else 
{
tilName.setErrorEnabled(false);
}

风格

<style name="error_appearance" parent="@android:style/TextAppearance">
<item name="android:textColor">@color/red</item>
<item name="android:textSize">12sp</item>
</style>
<style name="TextLabel" parent="TextAppearance.AppCompat">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">#4DFFFFFF</item>
<item name="android:textSize">@dimen/_20sdp</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="colorControlNormal">#4DFFFFFF</item>
<item name="colorControlActivated">@color/colorPrimary</item>
<item name="errorTextAppearance">@style/error_appearance</item>
</style>

Answer 1

将 TextLabeltheme父级更改为 Widget.Design.TextInputLayout 后，它现在可以工作了

<style name="TextLabel" parent="Widget.Design.TextInputLayout">
<item name="android:textColorHint">#4DFFFFFF</item>
<item name="android:textSize">@dimen/_20sdp</item>
<!-- Label color in TRUE state and bar color FALSE and TRUE State -->
<item name="colorAccent">@color/colorAccent</item>
<item name="colorControlNormal">#4DFFFFFF</item>
<item name="colorControlActivated">@color/colorPrimary</item>
</style>
