Question

我制作了一个滑动标签功能，目前正在使用。我也想让它可点击

public class MainActivity extends AppCompatActivity {
    public List<String> datafragmnt = new ArrayList<String>();
    public ViewPager viewPager;
    public pagerfragmetAdapter myAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        datafragmnt.add("Frgmnt 1 ");
        datafragmnt.add("Frgmnt 2 ");
        datafragmnt.add("Frgmnt 3 ");
        datafragmnt.add("Frgmnt 4 ");
        myAdapter = new pagerfragmetAdapter(getSupportFragmentManager());
        myAdapter.setMydata(datafragmnt);
        myAdapter.setFragmntList(new fragment1());
        myAdapter.setFragmntList(new fragment2());
        myAdapter.setFragmntList(new fragment3());
        myAdapter.setFragmntList(new fragment4());

        viewPager = (ViewPager) findViewById(R.id.viewPager);

        viewPager.setAdapter(myAdapter);
        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
    }
}

这是我到目前为止所尝试的。欢迎任何帮助！请帮帮我！

您需要为该视图页面创建一个适配器，如下所示：

 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);
        }
    }

在SetUpViewPager中，您可以像这样添加片段：

private void setupViewPager(ViewPager viewPager) {
        Main.ViewPagerAdapter adapter = new Main.ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFragment(new fragment1(), "FRAGN+MENT UNO");

如何让Sliding标签在Android开发中实现点击？
