将 android:drawableTop 添加到 xml 文件时应用程序崩溃答案

【问题标题】：App crashes when android:drawableTop is added to xml file将 android:drawableTop 添加到 xml 文件时应用程序崩溃

【问题描述】：

我正在处理一个 xml 文件，其中包括一个带有星数计数器的评分系统 - 它计算用户拥有的星数。现在这是 my_profile.xml 文件。在我的相对布局中，我想从矢量绘图中添加一个星号。我添加的行是这样的：

    android:drawableTop="@drawable/ic_icon_star"

我的文本视图看起来像这样：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".navdraweractivities.MyProfileActivity">
    ...
    <TextView
    android:id="@+id/textViewStars"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignBaseline="@+id/buttonEdit"
    android:layout_alignBottom="@+id/buttonEdit"
    android:layout_alignStart="@+id/textViewAbout"
    android:drawableTop="@drawable/ic_icon_star"
    android:gravity="center"
    android:text="0"
    android:textColor="#FFFFFF"
    android:textSize="18sp" />
    ...
</RelativeLayout>

当我将 ic_icon_star 添加到 imageView 时，它会起作用。我尝试添加不同的drawables和drawableLeft、drawableRight等，但结果相同。
