这两句代码是清理所有内存缓存和磁盘缓存，重新加载应该就行了。[/quote]重新加载时啥意思，每次进来都是重新走adapter加载一遍的呀

activity的ondestroy
protected void onDestroy()
{
if(EventBus.getDefault().isRegistered(this))
{
EventBus.getDefault().unregister(this);
}
Glide.get(MyApplication.getInstance()).clearMemory();
new Thread(new Runnable()
{
@Override
public void run()
{
Glide.get(MyApplication.getInstance()).clearDiskCache();
}
}).start();
setContentView(R.layout.activity_about);
super.onDestroy();
}

补充：activity销毁之后仍然占用内存，求解，用了网上其他人说的ondestroy的时候setcontentview弄个空layout也不行

用Glide.get(this)，你用了application，就和app的生命周期挂钩了，代码放到super.onDestroy();之后。加载图片的Glide也要用Glide.with(activity)初始化，不要用application。
