Question

我添加了一个ImageView并分配了一个jpg文件（a1.jpg），该文件是770Kb。当我运行项目时，会崩溃并显示大量错误日志。我已经尝试了另一个jpg文件，大小为70KB并运行项目，这没有问题。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。甚至你的错误也是如此：

Caused by: java.lang.OutOfMemoryError

对于Android应用程序，770KB的图像非常大。你应该考虑一些更小的东西。

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......听起来你的绘图可能没有正确设置。你确定这个名字等吗？

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（我相信它是Max VM应用程序堆大小）。

Answer 4

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