Answer 1

不能将主题设置为视图背景。在下面的代码中，该行可能会导致问题。

android:background="@style/AppBaseTheme"

相反，您应该使用可绘制对象。F

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/viewBackground"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    tools:context=".MainActivity" >
    <TextView android:id="@+id/textTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="86dp"
        android:text="@string/hello_world" />
    <Button android:id="@+id/buttonFlashlight"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textTitle"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="36dp"
        android:text="@string/hello_world" />
</RelativeLayout>
