我设计了一个自定义的 InputTextLayout,其中包含一个自定义的 Edittext。这个自定义的 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片段。
主要的.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>
MainActivity.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。
