您好我使用本教程中的网格视图创建了一个图库   http://www.androidhive.info/2012/02/android-gridview-layout-tutorial/

     

我将70张图片添加到 ImageAdapter.java 并运行app并强行关闭。

Q1：这个错误是什么？

     

Q2：创建图库图片的最佳方式???

5 个答案:

答案 0 :(得分：1)

你的图像尺寸太大。使用低尺寸图片

答案 1 :(得分：1)

不要一次性加载70张图像，使用lazy loading for loading images，也可以使用低维图像，特别是.png图像。

答案 2 :(得分：1)

Q1：它说：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：请参阅：http://developer.android.com/training/displaying-bitmaps/load-bitmap.html

我的ImageGallery库非常易于使用。这可能就是你所需要的。

https://github.com/lawloretienne/ImageGallery 

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);

  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>标签

只需复制属性...? 这将解决错误... 

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