Android 模拟器 ImageView 崩溃

Question

我已经添加了一个 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。我尝试了另一个 jpg 文件，大小为 70KB 并运行该项目，这没问题。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

这可能是因为您尝试加载的文件太大。甚至你的错误也是这样说的:

Caused by: java.lang.OutOfMemoryError

770KB 的图像对于 Android 应用程序来说是相当大的。你真的应该考虑一些更小的事情。

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