Question

我想在ImageView中加载图像。所以，我做了一个：

Intent gallery = new Intent();
    gallery.setType("image/*");
    gallery.setAction(Intent.ACTION_GET_CONTENT);

然后我们回到URI和媒体，然后将图像加载到ImageView中。

但是如果图像尺寸很大，我有以下例外：

帮帮我?? !!!

Answer 1

以前曾多次询问过这个问题。您需要对图像进行缩减采样，以便可以在ImageView中显示。有关解决方案，请参阅this question。请记住，图像需要W x H x 4 bytes存储在内存中并显示。

Answer 2

错误清楚地描述了dalvik VM不支持您的图像大小。如果您的图片尚未支持分辨率，请将其转换并尝试。如果已经在该分辨率中，则需要编辑和缩小图像的大小。
