【问题描述】：
这就是我正在做的事情
ImageView image2 = (ImageView) findViewById(R.id.imageView3);
image2.getDrawable().setCallback(null);
image2.setImageResource(R.drawable.fire);
其中 fire 是一个提出可绘制动画的 xml 文件
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<item android:drawable="@drawable/fire1" android:duration="50" />
<item android:drawable="@drawable/fire2" android:duration="50" />
<item android:drawable="@drawable/fire3" android:duration="50" />
<item android:drawable="@drawable/fire4" android:duration="50" />
<item android:drawable="@drawable/fire5" android:duration="50" />
...
<item android:drawable="@drawable/fire16" android:duration="50" />
我有这个错误

我阅读了很多关于内存泄漏、内存错误的帖子（例如java.lang.OutOfMemoryError: bitmap size exceeds VM budget - Android），但我没有成功解决我的问题
当我将 image2.setImageResource(R.drawable.fire); 替换为 image2.setImageResource(R.drawable.fire1); 时，其中 fire1 是一个简单的 png，一切正常
我能做些什么来解决我的问题
【问题讨论】：
-
要为视图设置动画，您应该使用“FrameAnimation”，其中您的所有项目都添加为框架并将该动画放入 ImageView。
-
我该怎么做才能使我添加的图像（使用 addFrame）与最初在 imageview 中的图像具有相同的尺寸。当我做 image2.getLayoutParams().height=FrameLayout.LayoutParams.WRAP_CONTENT; image2.getLayoutParams().width=FrameLayout.LayoutParams.FILL_PARENT; （imageview的初始条件）它不起作用
-
好的，我使用 fireAnimation.addFrame(new BitmapDrawable(decodeSampledBitmapFromResource(getResources(), R.drawable.fire1, 200, 200)),50);从你给的喜欢，它的工作原理谢谢！

如果它适合您，请接受答案。谢谢。我已经发布了答案。
