加载动画时出现 OutOfMemoryError。xml

Question

我有以下 ImageView:

imageView.setBackgroundResource(R.drawable.create_user);

我的 create_user 可绘制对象如下所示：

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">    
  <item android:drawable="@drawable/create_user_0" android:duration="500" />
  <item android:drawable="@drawable/create_user_1" android:duration="500" />
</animation-list>

但是当在 imageView.setBacgroundResource(R.drawable.create_user) 中设置 .xml 时，它会启动以下异常：

我不得不说我已经使用这个动画很久了。昨天是它第一次开始崩溃。

我无法想象此时发生了什么......谁能帮我找出我做错了什么？

注意：在错误启动之前显示Out of memory on a 638416-byte allocation。

注意 2: 在应用程序崩溃之前它也说了几次。

Answer 1

我也遇到过一次这种错误，但是当我调整图像大小时它就解决了。尝试重新调整图像的大小。

Answer 2

尝试在清单中添加 android:largeHeap="true", 看看是否可以解决问题。

或使用 api inSampleSize of bitmapfactory 对图像进行采样。

Answer 3

您可以尝试调整图像的大小以使其适应视图的确切大小，如 here. You can even try using libraries like universal image loader 所述，这会使这项任务更容易。
