When I had implemented something similar, I had done it in a nicer way, in the sense of classes. I had created the adapter in a package called working.
Below is the code:
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new WorkingFragment();
//You can add as many fragments as you wish here by adding the cases and calling the different fragments.
}
return null;
}
@Override
public int getCount() {
// get item count - equal to number of tabs. 4 is only the number of fragments I had used.
return 4;
}
}
You then need to create a new class called WorkingFragment
in the example I am giving. For the sake of clean coding, I created this class in the main package.
Below is the code for the fragment:
public class NewEventFragment extends Fragment {
View rootView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//reference the xml file containing the view with all the code here.
}
}
In the MainActivity
, you then need to make the functionality to change form one tab to another. In my case I had included this in the main package.
Below is the code for the MainActivity class:
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager ViewPager;
private TabsPagerAdapter SectionsPagerAdapter;
private ActionBar actionBar;
//Include the name for the tabs in this array. Make sure the number of elements in this string matches the number of views you will have in your app.
private String[] tabs = {};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialisation
ViewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
SectionsPagerAdapter = new TabsPagerAdapter(getSupportFragmentManager());
ViewPager.setAdapter(SectionsPagerAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
ViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction ft) {
}
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {
ViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction ft) {
}
}
Hope this has helped you achieve the necessary funtionality for your app :)
