无法为简单的TextView充气

Question

我的mainactivity文件没有一行代码，只有setContentView＆amp; onCreate方法。但我仍然在运行时遇到异常。 Drawable文件夹没有任何png或xml文件。

这是我的gradle依赖项：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
at android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
at android:paddingRight="@dimen/activity_horizontal_margin"
at android:paddingTop="@dimen/activity_vertical_margin"
at android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/final_result"
    android:text="Hello world"/>
</RelativeLayout>

这是XML：
