我有一个包含10个标签的滑动标签活动。在每个标签中，我显示了那十天的电影列表。从第1天开始到第10天。这就是我所做的，
公共类TabImageActivity扩展了AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_activity2);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setTitle("Screening");
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
viewPager.setCurrentItem(0, false);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new ImageFragment1(), "20th Nov.");
adapter.addFragment(new ImageFragment2(), "21st Nov.");
adapter.addFragment(new Day3Fragment(), "22nd Nov.");
adapter.addFragment(new Day4Fragment(), "23rd Nov.");
adapter.addFragment(new Day5Fragment(), "24th Nov.");
adapter.addFragment(new Day6Fragment(), "25th Nov.");
adapter.addFragment(new Day7Fragment(), "26th Nov.");
adapter.addFragment(new Day8Fragment(), "27th Nov.");
adapter.addFragment(new Day9Fragment(), "28th Nov.");
adapter.addFragment(new Day10Fragment(), "29th Nov.");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);

答案 0 :(得分：3)
对于其中一个项目，我有相同的布局，大约10个选项卡使用相同的片段。例如，我有一个名为Movie Fragment的片段，然后我有一个看起来像这样的新实例方法。
public static MovieFragment newInstance(String movieUrl) {
FeedFragment fragment = new FeedFragment();
Bundle args = new Bundle();
args.putString("url", movieUrl);
fragment.setArguments(args);
return fragment;
}
然后你需要做的就是有一个方法可以像这样从
中获取数据 public void getBundleInformation() {
if (getArguments().containsKey("url") {
movieUrl = getArguments().getString("url");
}
}
然后你的适配器看起来像这样
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(MovieFragment.NewInstance(url), "20th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "21st Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "22nd Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "23rd Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "24th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "25th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "26th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "27th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "28th Nov.");
adapter.addFragment(MovieFragment.NewInstance(url), "29th Nov.");
viewPager.setAdapter(adapter);
}
