在选项卡视图之间滑动几次后膨胀异常

Question

我正在使用 TabLayout 集与 ViewPager 一起在 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，但几次后它崩溃并在我的第一个片段的 onCreateView() 方法中给我一个 Inflate Exception。这是错误代码：

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);
}

我的片段 class 扩展 android.support.v4.app.Fragment。它只会在几次滑动后给出错误，而不是当我一开始运行应用程序时。我在另一个Fragment classes.

中使用了与上面相同的方法

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 class:

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，到处都在寻找这个错误，但我发现没有一个案例与我的相似。预先感谢您的帮助。

Answer 1

尝试添加 viewPager.setOffscreenPageLimit(2);

这将防止您的视图分页器破坏以前的片段。所以我希望您不会遇到该错误。
