我有20个imageview，我有20个按钮为他们当我点击任何1个按钮它给我选择从画廊或相机选择图像，当我选择任何选项，例如厨房它将带我到画廊，让我从他们中选择图像，让我在我的imageview上显示这些图像的相应按钮 现在问题是有时当我做上述整个过程时，我的活动正在以电子方式重新启动，所有首次选择的图像都从他们的imageview中消失了 对于Refernce，我的代码如下：

看起来正在重新创建活动。 尝试将以下内容添加到清单
中的活动条目中 android:configChanges="orientation|keyboardHidden" android:launchMode="singleTask"
答案 1 :(得分：0)
问题可能是由于内存利用率的原因。尝试使用Memory Analyzer Tool测试代码，以便识别问题。
如果您在重新创建活动期间发布日志语句，我可以帮助您更好。
