Android 碎片StatePageRadapter性能问题，碎片数未知

这么长时间以来，我一直在寻找一个可靠的答案来解决我的性能问题。但我还没找到答案，据我所知，每个人都对此感到困惑

基本上，我在一个活动中有一个新闻列表（在listview中显示为标题），在我的详细信息活动中有一个新闻对象的详细信息。我已将“详细信息”活动更改为保留扩展FragmentStatePagerAdapter的viewpager。我的主要头条新闻通常是20/25

当用户单击单个listview项目时，它会将新闻列表传递给下一个活动：

Intent intent = new Intent(getApplicationContext(), Detail.class);
bundle.putInt("pos", i);
intent.putExtra("news", newsList);
intent.putExtras(bundle);
startActivity(intent);

“我的详细信息”活动从“标题”活动中获取捆绑数据，并准备适配器：

fm = getSupportFragmentManager();
news = (ArrayList) getIntent().getSerializableExtra("news");
current = getIntent().getExtras().getInt("pos");
fragments2 = new ArrayList<Fragment>();

vpPager = (ViewPager) findViewById(R.id.vpPager);

adapterViewPager = new ViewFlipperAdapter(current, getApplicationContext(), fm, news, handler, version());
vpPager.setAdapter(adapterViewPager);
vpPager.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

vpPager.setCurrentItem(current);
vpPager.setOnPageChangeListener(Detail.this);

问题是，当我单击单个列表项时，它会显示单个新闻项的详细信息。在这之前，我看不出有什么不对劲。但当我在不同的视图之间滑动时，应用程序一次又一次地处理视图的速度变得非常慢。此外，我跳转的页面与我设置的数据不一致。（滑回上一个视图会导致重新加载视图。）

我怎样才能克服这个问题？（顺便说一句，我正在使用fedorvlasov的延迟加载库和DFPSDK，它们分别针对每个视图进行初始化。）

-另外，我试过ViewPager.setOffScreenPageLimit（），但似乎效率不高

提前谢谢。

为什么要禁用硬件加速？好的，我将删除它并尝试一下。仍然出现性能问题。你找到答案了吗？没有，我找不到。你有答案吗？
