我正在使用TabLayout设置与ViewPager一起使用以在3个片段之间滑动。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。这是错误代码：

以下是给出错误的代码：
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_2, container, false);
}
My Fragment类扩展了android.support.v4.app.Fragment。 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。我在其他Fragment类中使用与上面相同的方法。
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);
}
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;
}
}
我不知道出了什么问题，到处都看过这个错误，但我发现的情况与我的相似。感谢您的帮助。
答案 0 :(得分：3)
尝试添加viewPager.setOffscreenPageLimit(2);
这会阻止你的浏览寻呼机破坏以前的碎片..所以我希望你不会得到那个错误。
