Answer 1

引起：java.lang.OutOfMemoryError

您需要缩小图像。它占据了太多导致OOM的空间。我认为从api 3.0开始，位图像素数据存储在堆上。

Out of Memory error with Bitmap

引用文档

如果您的应用已达到堆容量并尝试分配更多内存，它将收到一个OutOfMemoryError。

有效地检查加载图像@

同时检查

Answer 2

错误是由 java.lang.OutOfMemoryError

引起的

这取决于您的位图有多大，当您在计算机上读取大小时，Android似乎会分配比图像大小更多的空间。所以......

您可以使用较小的图片。
谷歌实际上已经发布了一个关于避免OutOfMemoryErrors的指南，这将有很大帮助，但我也必须使用较小的图像尺寸。
一种几乎肯定会起作用的方法是在清单中，在应用程序标记之间设置android：largeHeap =“true”。这会增加你的堆大小，但可能会使你的应用程序滞后一点。

也许对你而言，这些想法的组合将起作用。

请参阅此Link for Displaying Bitmaps Efficiently

或

以编程方式将图像添加到图像视图

if(imageView != null) { ((BitmapDrawable)imageView.getDrawable()).getBitmap().recycle(); imageView = (ImageView) view.findViewById(R.id.imageView); imageView.setImageResource(resID); } else { imageView = (ImageView) view.findViewById(R.id.imageView); imageView.setImageResource(resID); }
