我知道我可以给 setOffscreenPageLimit(int) 的最小数字是 1.但由于内存问题，我需要一次加载一页.
I understand the lowest number I can give setOffscreenPageLimit(int) is 1. but I need to load one page at a time because memory problems.
我将不得不使用旧样式的 tabhost 等吗?或者有没有办法/hack我可以让我的viewPager一次加载一个页面?
Am i going to have to use the old style tabhost etc? or is there a way/hack I can make my viewPager load one page at a time?
我的适配器使用 ViewHolder 模式扩展 BaseAdapter.
My Adapter extends BaseAdapter with the ViewHolder patern.
我遇到了同样的问题，我找到了解决方案:
步骤:
1) 首先从 CustomViewPager 类shared&resourcekey=0-tKADcOLf61mco5p5C-Ca5w" rel="nofollow noreferrer">这个链接.
1) First Download the CustomViewPager Class from this link.
2) 如下所述使用该类:
在 Java 中:
CustomViewPager mViewPager;
mViewPager = (CustomViewPager) findViewById(R.id.swipePager);
mViewPager.setOffscreenPageLimit(0);
在 XML 中:
<com.yourpackagename.CustomViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipePager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
现在一次只会加载一个页面.
P.S:根据问题的要求，我已经发布了 Viewpager 的解决方案.我还没有对 TabLayout 进行同样的尝试.如果我能找到任何解决方案，我会更新答案.
P.S: As per the question's requirement, I have posted the solution for Viewpager. I haven't tried the same with TabLayout yet. If I will find any solution for that I will update the answer.
