android中带有gridview的图片库

Question

嗨，我从本教程创建了一个带有网格视图的图片库 http://www.androidhive.info/2012/02/android-gridview-layout-tutorial/

我将 70 个图像添加到 ImageAdapter.java 并运行应用程序并强制关闭。

Q1：这是什么错误？

Q2：创建图库图片的最佳方式是什么？？？

Answer 1

Q1：上面写着：java.lang.OutOfMemoryError: bitmap size exceeds VM budget
这意味着您正在尝试加载太大的图像。它不能保存在 VM 堆内存中。

Q2：见：http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

Answer 2

你的图片太大了。使用低尺寸图片

Answer 3

不要一次加载70张图片，使用lazy loading for loading images，也可以使用低维图片，尤其是.png图片。

Answer 4

我的 ImageGallery 库使用起来非常简单。这可能是您需要的。

Intent intent = new Intent(MainActivity.this, ImageGalleryActivity.class);

ArrayList<String> images = new ArrayList<>();

images.add("https://images.unsplash.com/photo-1437422061949-f6efbde0a471?q=80&fm=jpg&s=e23055c9ba7686b8fe583fb8318a1f88");

intent.putStringArrayListExtra("images", images);
// optionally set background color using Palette
intent.putExtra("palette_color_type", PaletteColorType.VIBRANT);

startActivity(intent);

Answer 5

1. 打开您的 AndroidManifest.xml 文件。
2. 寻找<application>标签
3. 将以下属性添加到您的 <application> 标记中

只需复制属性...? 这将解决错误...

<application
      android:hardwareAccelerated="false"
      android:largeHeap="true">
 </application>
