我将手机从8.0更新到8.1,现在当我尝试在我的应用程序(使用API​​级别25构建)上点击任何EditText或com.rengwuxian.materialedittext.MaterialEditText时,我遇到了这个崩溃.

布局如下：

android:id="@+id/usernameET"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_marginBottom="@dimen/padding_xlarge"

android:layout_marginTop="@dimen/padding_large"

android:enabled="@{!loading}"

android:hint="@string/username"

android:inputType="text"

android:lines="1"

android:maxLength="50"

android:maxLines="1"

android:singleLine="true"

android:textSize="@dimen/text_normal"

app:met_accentTypeface="fonts/averta_bold.otf"

app:met_floatingLabel="highlight"

app:met_floatingLabelText="@string/username"

app:met_primaryColor="@color/text_dark"

app:met_textColor="@color/text_blue"

app:met_typeface="fonts/averta_regular.otf" />

你能否告诉我为什么会这样,以及如何解决这个问题？

先感谢您！！！
