Android force关闭imageview

Question

在文件夹res/drawable /我已经存储了我的图像pic.jpg，但是当我在设备上运行应用程序时，应用程序关闭。 android项目是自动生成的，除了我改变了将所有内容包含在LinearLayout中的RelativeLayout。在这个LinearLayout的内部，我只编写了一个ImageView。应用程序关闭不显示任何内容。请问我做错了什么？

相关的XML：

<ImageView 
    android:layout_width="85dp" 
    android:layout_height="85dp" 
    android:src="@+drawable/pic" 
    android:contentDescription="@string/none" 
/> 

这里是logcat的：

Answer 1

android:src="@+drawable/pic" 

应该是没有+标志。访问/res/drawable资源是不变的 - 它们不能动态生成，所以+不应该工作。

android:src="@drawable/pic" 

另外，还要确保您的pic图片文件是复制到提拉文件夹。从文件系统链接是不一样的，因为文件夹中不是实际上是。链接将导致no resource found that matches the given name错误。
