Question

我面临一个奇怪的问题而不是我不知道如何解决：我已经准备好了一个带浮动操作按钮（fab）的布局。在模拟器中它可以很好地工作，但是当在真实设备中执行我的应用程序时，它会避免运行时异常：

java.lang.RuntimeException: Unable to start activity ComponentInfo{soyacm.es.com.bookgame/soyacm.es.com.bookgame.ui.bookDetail.BookDetailActivity}: android.view.InflateException: Binary XML file line #183: Error inflating class android.support.design.widget.FloatingActionButton

异常将我直接引导到setContentView（R.layout.activity_book_detail）;线

模拟器使用Android API24运行，设备使用API 22和API 23运行（均失败）。

这是我在gradle文件中导入的库：

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

我的布局如下（缩小）：

<android.support.design.widget.CoordinatorLayout>
    <android.support.v4.widget.NestedScrollView>
       ...
    </android.support.v4.widget.NestedScrollView>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/read_book_action"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="16dp"
        android:src="@drawable/read_book_icon"
        android:backgroundTint="@color/not_so_white_background"
        android:elevation="6dp"
        />
</android.support.design.widget.CoordinatorLayout>

有人找出错误的位置吗？

Answer 1

尝试编辑此行.. volumes: name: driver: local driver_opts: type: nfs o: addr=192.168.1.1,rw device: ":/path/to/dir"

android:backgroundTint="@color/not_so_white_background"

要

<android.support.design.widget.FloatingActionButton
    android:id="@+id/read_book_action"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:layout_margin="16dp"
    android:src="@drawable/read_book_icon"
    android:backgroundTint="@color/not_so_white_background"
    android:elevation="6dp"
 />

Android浮动操作按钮在真实设备上失败，但在模拟器中失败
