android - 材料组件库版本 1.1.0 不工作

Question

我想使用材料组件库版本 1.1.0 中存在的 startIconDrawable 功能。但是当我从版本 1.0.0 升级到版本 1.1.0 时，轮廓框消失并且活动崩溃。请帮忙

 <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/username"
        android:layout_marginTop="20dp"
        android:hint="Username"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
    </com.google.android.material.textfield.TextInputLayout>
