Android gridadapter中的内存泄漏找不到位置？如何改进逻辑以避免GC调用？

由于GC调用导致滚动时出现延迟，如何改进逻辑以减少内存消耗和快速UI。

I用户Eclipse MAT发现了3个嫌疑犯：

问题可疑1

由“”加载的“android.graphics.Bitmap”的一个实例占用500464（14.70%）字节。内存累积在由“”加载的“byte[]”的一个实例中

问题嫌疑犯2

由“”加载的2906个“java.lang.Class”实例占用1121048（32.92%）字节

最大的例子：

•class android.text.Html$HtmlParser @ 0xb4ef4448 - 126,720 (3.72%) bytes. 
•class org.apache.harmony.security.fortress.Services @ 0xb4ee7b48 - 80,120 (2.35%) bytes. 
•class libcore.icu.TimeZones @ 0xb4e0d2b0 - 69,144 (2.03%) bytes. 
•class java.lang.ref.FinalizerReference @ 0xb4e07ef0 - 59,080 (1.74%) bytes. 
•class com.android.internal.R$styleable @ 0xb4e2ddd0 - 57,192 (1.68%) bytes. 
•class android.R$styleable @ 0xb4e74e78 - 52,896 (1.55%) bytes. 
•class android.view.View @ 0xb4e2c228 - 46,344 (1.36%) bytes. 

问题可疑3

由“”加载的8040个“java.lang.String”实例占用514408（15.11%）字节
