android - 应用程序已在 android 模拟器中停止

Question

我是 Android Studio 的新手，我只是想创建一个简单的应用程序，例如折叠工具栏布局，但在我运行该程序后它突然停止了，我想知道为什么会这样？这个问题有解决办法吗？

这是我的代码:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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=".MainActivity"
    android:background="#fcfcfc">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        >

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/CollapsingToolbar"
            android:layout_height="match_parent"
            android:layout_width="match_parent"
            app:layout_scrollFlags="exitUntilCollapsed|scroll"
            app:contentScrim="?attr/colorPrimary"
            app:title="App Title"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleMarginEnd="64dp"
            android:background="@drawable/backmaterial">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbarid"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                app:layout_collapseMode="pin"
                android:layout_height="?attr/actionBarSize"
                android:layout_width="match_parent"
                >

            </android.support.v7.widget.Toolbar>
        </android.support.design.widget.CollapsingToolbarLayout>

    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

Answer 1

堆栈跟踪显示:

Error inflating class android.support.design.widget.CollapsingToolbarLayout

它还写着:

Caused by: android.content.res.Resources$NotFoundException: Resource "com.miyuki.ouka.collapsetollbar:drawable/backmaterial" (7f07005d)

NotFoundException 可以通过以下方式修复:

• 添加引用的资源文件drawable/backmaterial.xml

• 删除行 android:background="@drawable/backmaterial"
