I'm using PagerSlidingTabStrip library for ViewPager https://github.com/astuetz/PagerSlidingTabStrip. I want to change the fragments while scrolling. I achieved that with the below code.
MainActivity.java
public class MainActivity extends SherlockFragmentActivity {
private MyPagerAdapter adapter;
ViewPager pager;
private PagerSlidingTabStrip tabs;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
pager = (ViewPager) findViewById(R.id.pager);
adapter = new MyPagerAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
final int pageMargin = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 4, getResources()
.getDisplayMetrics());
pager.setPageMargin(pageMargin);
tabs.setViewPager(pager);
}
public class MyPagerAdapter extends FragmentPagerAdapter {
private final String[] TITLES = {"First","Second","Third"};
private SherlockFragment[] fragments = new SherlockFragment[] { new FirstFragment(), new SecondFragment(), new ThirdFragment()};
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public CharSequence getPageTitle(int position) {
return TITLES[position];
}
@Override
public int getCount() {
return TITLES.length;
}
@Override
public Fragment getItem(int position) {
return fragments[position];
}
}
}
FirstFragment.java
public class FirstFragment extends SherlockFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.fragment_main, container, false);
Toast.makeText(getSherlockActivity(), "This is from first", Toast.LENGTH_SHORT).show();
return v;
}
}
SecondFragment.java
public class SecondFragment extends SherlockFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.fragment_main, container, false);
Toast.makeText(getSherlockActivity(), "SecondFragment", Toast.LENGTH_SHORT).show();
return v;
}
}
ThirdFragment.java
public class ThirdFragment extends SherlockFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.fragment_main, container, false);
Toast.makeText(getSherlockActivity(), "ThirdFragment", Toast.LENGTH_SHORT).show();
return v;
}
}
I got the three fragments and I'm testing them with Toasts.
When the application opens with the MainActivity, FirstFragment is attached to the Activity , but it shows two toasts, one from Firstragment and other from SecondFragment , and when I scroll to second tab, it shows the toast of ThirdFragment.
So, I figured its going like this. If I scroll from left to right , the fragment right to the current fragment is displayed and if I scroll from right to left, the fragment left to the current fragment is displayed. Please help.
Thanks.
