在选项卡视图之间滑动几次后膨胀异常
[英]inflate exception after swiping between tab views a few times
问题描述
I am using a TabLayout set to work with a ViewPager to swipe between 3 Fragments. 
我正在使用TabLayout设置与ViewPager一起使用以在3个片段之间滑动。 The app is able to inialize an switch between tabs but after a few times it crashes and gives me an Inflate Exception in the onCreateView() method of my 1st fragment. 该应用程序能够初始化选项卡之间的切换，但几次崩溃后，在我的第一个片段的onCreateView（）方法中给了我一个Inflate Exception。 Here is the error code: 这是错误代码：

Here's the piece of code that is giving the error: 这是给出错误的代码片段：
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_2, container, false);
}
My Fragment class extends android.support.v4.app.Fragment. My Fragment类扩展了android.support.v4.app.Fragment。 It only gives the error after a few swipes, not when I run the app at first. 它只会在几次滑动后给出错误，而不是在我首先运行应用程序时。 I use the same method as above in the other Fragment classes. 我在其他Fragment类中使用与上面相同的方法。
Here's how I am setting up the TabLayout and the View Pager on my MainActivity: 以下是我在MainActivity上设置TabLayout和View Pager的方法：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// ViewPager
ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
setupViewPager(viewPager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
}
private void setupViewPager(ViewPager viewPager)
{
Fragment2 f2 = new Fragment2();
Fragment1 f1= new Fragment1();
Fragment3 f3 = new Fragment3();
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(f2, "ONE");
adapter.addFragment(f3, "TWO");
adapter.addFragment(f1, "THREE");
viewPager.setAdapter(adapter);
}
And here's my ViewPagerAdapter class: 这是我的ViewPagerAdapter类：
public class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<android.support.v4.app.Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager)
{
super(manager);
}
@Override
public android.support.v4.app.Fragment getItem(int position)
{
return mFragmentList.get(position);
}
@Override
public int getCount()
{
return mFragmentList.size();
}
public void addFragment(android.support.v4.app.Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position)
{
return null;
}
} }
I have no idea what's wrong and have looked everywhere about this error but no case I found is similar to mine. 我不知道什么是错的，并且到处都看到了这个错误，但我发现的情况与我的相似。 Thank you for the help in advance. 感谢您的帮助。

Try adding viewPager.setOffscreenPageLimit(2); 尝试添加viewPager.setOffscreenPageLimit(2);
This will prevent your view pager from destroying previous fragments.. So I hope you will not get that error. 这将阻止您的视图寻呼机破坏以前的片段..所以我希望你不会得到那个错误。
