我的布局非常复杂。我必须使整页可滚动，所以我所做的是 - 我有一个用于我的 gridview 项目的 gridView 适配器和一个具有四个选项卡的自定义适配器，然后我在那个自定义适配器中设置我的 gridview。然后整个视图设置在我的主要活动上，该活动有一个列表视图，所以它现在滚动整页，但问题在于内存。
我在自定义适配器上有 4 个选项卡单击事件，我通过将这些单击事件发送到我有四个 Web 服务的主要活动，并且条件是如果选择了第一个选项卡，则将发生第一个 Web 服务调用并设置新适配器关于主要活动。
问题：当我单击第一个选项卡时，我的内存大小为 130 MB，单击第二个选项卡时它会增加一倍，所以当我单击第三个选项卡时也会发生同样的事情。我正在使用延迟加载来加载我的图像，这也维护了我的缓存，我尝试了 clear()、notifyDataSetChanged() 但没有做任何更改。每次点击标签时，我的记忆都会增加。
这是我的代码：
