gridview
基本上我有一个gridview，我在其中显示我的产品（从10或20到1K +项目），每个项目都有几个自定义文本视图和一个Imageview。
我使用ViewHolder模式和Picasso库来异步加载图像。我没有显示项目，速度或任何问题，所以我认为我的getview功能非常好，虽然我有一个主要问题，即滚动网格视图，上下，我的记忆，这是安全的。监视器仅显示增加当然增量率取决于项目视图内容，例如当我评论图像加载部分时，速率降低。
我猜是生成的视图总是停留在内存中，而某些东西会阻止它们被GC收集。 虽然有时候，当我慢慢地滚动时GC会收集并且内存自由，但是快速滚动总会导致OOM迟早。
我的主要问题是，如果我有内存泄漏？！因为gc有时会工作（缓慢的scrlling），有时会让应用程序崩溃与OOM异常。
显然我希望能够找到我的问题，并提前感谢每一点帮助。
承载Gridview的片段布局的xml：
<GridView
android:id="@+id/gv_Main"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:animationCache="false"
android:clickable="true"
android:descendantFocusability="beforeDescendants"
android:gravity="center"
android:scrollingCache="false"
android:verticalSpacing="10dp"
/>

这是我设置适配器的java代码中的一部分：
ShygunInventoryGridCursorAdapter listAdapter1 = new ShygunInventoryGridCursorAdapter(context,cursor, CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
gridView.setNumColumns(colCount);
gridView.setAdapter(listAdapter1);
MAT屏幕（我无法到达任何地方，我的意思是非根或......是我自己的代码）
更不用说，在适配器的System.gc()方法末尾添加get View将解决所有问题，但我确定它不是正确的做法
