java - Android:无法将FloatLabeledEditText转换为EditText

我正在尝试从模板复制设计，但是出现转换错误。我是使用3rd party库和Android编程的新手，所以我希望这不会成为问题。

另外，我有2个文本字段和2个按钮（注册，登录）。谁能看到我正确设置的登录代码type来告诉我。非常感谢。

如果需要其他文件或信息，请告诉我。参考模板甚至没有处理Java代码中的输入，因此我不知道该如何命名。

这是每个UI文件扩展的内容：

公共类FontelloTextView扩展了TextView
公共类FloatLabeledEditText扩展LinearLayout
公共类MaterialRippleLayout扩展了FrameLayout {
公共类RobotoTextView扩展了TextView {

谢谢.. ：-）

最佳答案

FloatLabeledEditText太多。所以我不知道您使用的是哪种FloatLabeledEditText。

 

至

     <mypackage.restaurantlunchify.Templates.FloatLabeledEditText
            android:id="@+id/usernameTextFloat"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginLeft="16dp"
            android:layout_weight="1"
            app:fletHintTextColor="@color/main_color_A100"
            app:fletSingleLine="true"
            app:fletFloatingHint="Username"
            app:fletTextColor="@color/main_color_grey_50">

<EditText @+id/usernameText android:layout_height="wrap_content" android:layout_width="match_parent" />

<mypackage.restaurantlunchify.Templates.FloatLabeledEditText/>
