我有一个ViewPager，它显示新闻条目的详细信息。您可以来回切换30个条目。这些条目中的每一个都是一个包含ImageView的视图。此ImageView使用Picasso图像库填充了URL中的图像。
它运行正常，但有时当我浏览几乎所有各种项目（片段）时，我的应用程序突然崩溃，收到此错误：

在刷卡期间，我有时会得到以下Logcat消息（当前视图包含加载到ImageView中的大图像时）：
09-25 13:19:59.816 31859-32208/com.app.mobile E/dalvikvm-heap﹕ Out of memory on a 3276816-byte allocation.
我对整个事情有一个担忧：我用Picasso加载到ImageViews中的图像有时非常大（每张图像约3MB）。
有人可以向我解释我做错了吗？
答案 0 :(得分：2)
试试这个：
android:largeHeap="true"
，应用程序标记
答案 1 :(得分：0)
使用以下代码将图像转换为布局以减小内存大小 -
Picasso.with（context）.load（url）.resize（width，height）.into（imageView）
确保您使用的是带有版本的Picasso库 - 2.3.4
