Question

我的应用程序在添加溅屏后崩溃。下面是错误日志、xml和java文件。我在其他应用程序中大多使用了相同的代码，但我不明白为什么它在这里不起作用，请帮助

Answer 1

由: java.lang.OutOfMemoryError引起

你需要缩小你的形象。它占据了太多的空间导致了OOM。我认为从API3.0开始，位图像素数据存储在堆中。

位图内存不足错误

引用文档

如果应用程序达到了堆容量并试图分配更多内存，它将收到一个OutOfMemoryError。

有效检查加载图像@

http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

也要检查

查一下这个

Answer 2

这个错误是由java.lang.OutOfMemoryError引起的。

这取决于你的位图有多大，当你在电脑上读取图片大小时，Android似乎比图像的大小多了一点空间。所以..。

• 你只需要一个小一点的图像。
• 谷歌实际上已经出版了一本关于避免OutOfMemoryErrors的指南，这将对我有很大的帮助，尽管我不得不使用更小的图像大小。
• 一个几乎肯定有效的方法是在您的清单中，在应用程序标记之间设置android:largeHeap="true“。这将增加您的堆大小，但可能会使您的应用程序有点滞后。

也许对你来说，把这些想法结合起来是可行的。

参见此有效显示位图的链接

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);
}
