标签： android android-layout android-studio

我创建了一个应用程序，其中我使用了一个背景活动。当我在手机中运行应用程序时，我无法看到我使用的背景，但活动正常运行，当我使用模拟器运行应用程序时：NEXUS 5，活动无法加载，应用程序崩溃。 这是logcat：

这是我使用背景的布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity"
    android:background="@drawable/back"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
