这整个内存泄漏对我来说似乎很复杂。这里有很多很棒的信息，但我不太明白。即使在阅读Creating a memory leak with Java之后，我仍然迷失了！有人可以向我指出这段代码中的内存泄漏在哪里，好吗？ （当这个方法重复运行时会发生这种情况。）非常感谢你！

在java中，内存使用过多的常见原因是在某种循环中（例如游戏循环）分配而不是销毁对象。您是否在循环中添加动态数组/排序列表？此外，如果方法需要一段时间，则在销毁之前，局部变量可能会发生这种影响。

如果您经常更改图片，则需要使用ImageView执行此操作
Drawable obj = imgView.getDrawable（）;
if( obj instanceof BitmapDrawable)
{
Bitmap bmp = obj.getBitmap();
bmp.Recycle();
}
在此语句之前调用cleanupcode函数
Bitmap CleanupCode(ImageView imgView) {
Drawable obj = imgView.getDrawable();
if( obj instanceof BitmapDrawable) {
Bitmap bmp = obj.getBitmap(); bmp.Recycle(); return bmp;
}
return null;
}
////
Bitmap bmp = CleanupCode(c);
c.setImageResource(R.drawable.clubs3);
if(null != bmp) {
bmp.Recycle();
bmp = null;
}
