android - PagerSlidingTabStrip指示灯不随页面变化？

Question

它适用于我的搜索 Activity 页面，但不适用于我的个人资料 Activity :所选选项卡下的指示灯，我是否必须添加一些东西
这是代码:

public class ProfileActivity extends AppCompatActivity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_profile);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

 String[] tabTitles =  {"Completed", "Joined"};
        adapter = new TabAdapter(getSupportFragmentManager(), profileCompletedFrag, profileJoinedFrag, tabTitles);

//        // Initialize the ViewPager and set an adapter
        pager = (ViewPager) findViewById(R.id.profilePager);
        pager.setAdapter(adapter);

        // Bind the tabs to the ViewPager
        tabs = (PagerSlidingTabStrip) findViewById(R.id.profileTabs);
        tabs.setViewPager(pager);

 /**
         * on swiping the viewpager make respective tab selected
         * */
        tabs.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

            @Override
            public void onPageSelected(int position) {
                // on changing the page
                if (position == 0) {
                    currentPage = 0;
                    pager.setCurrentItem(0);


                }
                if (position == 1) {
                    currentPage = 1;
                    pager.setCurrentItem(1);

                }

            }

            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }

            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });
        /////////////
        tabs.setOnTabReselectedListener(new PagerSlidingTabStrip.OnTabReselectedListener() {
            @Override
            public void onTabReselected(int position) {
                Toast.makeText(ProfileActivity.this, "Tab reselected: " + position, Toast.LENGTH_SHORT).show();
                if (position == 0) {
                    currentPage = 0;
                     pager.setCurrentItem(0);
                }
                if (position == 1) {
                    currentPage = 1;
                    pager.setCurrentItem(1);
                }
            }
        });

Answer 1

 public class TabAdapter  extends FragmentStatePagerAdapter {

    String[] tabTitles =  {"Completed", "Joined"};

    public TabAdapter(FragmentManager fragmentManager) {
        // TODO Auto-generated constructor stub
        super(fragmentManager);
    }


    @Override
    public CharSequence getPageTitle(int position) {
        // TODO Auto-generated method stub
        return tabTitles[position];
    }


    @Override
    public Fragment getItem(int arg0) {

        switch (arg0) {
        case 0:
            return ProfileDataFagment.newInstance(0);
        case 1: 
            return ProfileDataFagment.newInstance(1);
        default:
            break;
        }

        return null;

    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return 2; // Number of views  
    }


}

//同时创建 ProfileDataFagment 并根据你的位置设置你的数据
