BitmapFactory中的内存不足错误

Question

今天我的应用程序崩溃,内存不足错误.

android.graphics.BitmapFactory.nativeDecodeAsset中的java.lang.OutOfMemoryError

我只使用Bitmap Factory为我的操作栏制作了一个背景

代码:

BitmapDrawable background = new BitmapDrawable (BitmapFactory.decodeResource(getResources(), R.drawable.actionbar)); 
         background.setTileModeX(android.graphics.Shader.TileMode.REPEAT); 
         actionbar.setBackgroundDrawable(background);

活动开始时不会发生此错误,它会在更改活动后发生.

有人可以告诉我如何解决这个问题

Answer 1

您的代码中存在内存泄漏.考虑使用WeakReference,WeakHashMap或SoftReference来避免强引用.在onLowMemory活动方法上释放未使用的资源和变量.

你也可以使用该选项BitmapFactory.Options位图解码的显示例子在这里.
