我关注了如何在Android上制作标签式应用的在线视频。在视频上它工作正常,但我收到此错误,无法找到任何解决方案。
这是一个非常基本的应用程序,错误没有意义。该应用程序只有3个空片段和一个主要活动。我甚至没有任何数据。该错误甚至没有报告我的代码的任何行!

这是我的主要课程
public class MainActivity extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// List of all fragments
List<Fragment> mFragmentList = new ArrayList<>();
mFragmentList.add(new NewsFragment());
mFragmentList.add(new OffersFragment());
mFragmentList.add(new ProductsFragment());
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager(), mFragmentList);
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
// FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
// fab.setOnClickListener(new View.OnClickListener() {
// @Override
// public void onClick(View view) {
// Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
// .setAction("Action", null).show();
// }
// });
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
我试着看看其他答案,但这没有意义,我在哪里请求任何记忆?
我的SectionsPagerAdapter
public class SectionsPagerAdapter extends FragmentPagerAdapter {
List<Fragment> listFragments;
public SectionsPagerAdapter(FragmentManager fm, List<Fragment> listFragments) {
super(fm);
this.listFragments = listFragments;
}
@Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class below).
return listFragments.get(position);
}
@Override
public int getCount() {
// Show 3 total pages.
return listFragments.size();
}
}
