Question

我试图实现浮动EditText的新Material Design，但我遇到了错误。所以，我正在使用最新的Android支持设计库＆＃39;谷歌于2015年5月29日发布。根据说明，我按照以下内容通过build.gradle文件编译库：

compile 'com.android.support:design:22.2.+'

根据Android Developers Blog：

虽然EditText单独会在输入第一个字符后隐藏提示文本，但您现在可以将其包装在TextInputLayout中，从而使提示文本成为EditText上方的浮动标签，从而确保用户永远不会丢失它们的上下文正在进入。

所以，这是我在布局xml文件上的代码，有问题的代码的id为android：id =＆＃34; @ + id / viewTest＆＃34;和android：id =＆＃34; @ + id / fNameTest：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainFragmentViewGroup"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

知道为什么会发生这些错误？

Answer 1

所以我发现了问题所在。如果确保将styles.xml上的主题设置为：

，问题就会消失

modalInstance.result.then(function (entity) {...});

这解决了我的问题。以前我有＆＃34;材料＆＃34;到位。
