Android模拟器ImageView崩溃

Question

我添加了ImageView并分配了一个jpg文件（a1.jpg），该文件是770Kb。当我运行该项目时，会崩溃并显示很多错误日志。我已经尝试另一个JPG文件，大小为70KB并运行该项目，这成为没有问题。为什么？谢谢！

<ImageView 
    android:id="@+id/imageView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_centerHorizontal="true" 
    android:contentDescription="@string/Test_string" 
    android:src="@drawable/a1" />

Answer 1

这可能是因为你试图加载太大的文件。即使你的错误这样说：

Caused by: java.lang.OutOfMemoryError 

770KB对于android应用程序的图像是相当大的。你应该考虑更小的东西。

您还可以在AVD中增加模拟器的堆大小，但在您的情况下，如果可以，最好使用较小的图像。

Answer 2

嗯...这听起来像你绘制的设置可能不正确。你确定名字等吗？

Answer 3

模拟器无法支持那么大的图像，如java.lang.OutOfMemoryError所示。您应该能够通过进入AVD管理器来自定义模拟器以允许更大的内存（我相信这是最大的VM应用程序堆大小）。

Answer 4

我有同样的问题，并且Piotr Chojnacki是对的;这是一个图像尺寸问题。我认为这对老设备和模拟器来说更是一个问题。
