I am trying to change the Fragment onTabSelected
.
Because at the moment, if you swipe the transitions work fine. But if you click on the Tab
, the Fragments won't switch. The Tab
gets highlighted, but the content remains the same.
The issue is with my onTabSelected
method. I need a suggestion on how to switch to Fragments onTabSelected
.
Unfortunately I cannot extend my MainActivity
to FragmentActivity
, since I won't be able to use ActionBar
in that case (I am required to extend ActionBarActivity
).
onTabSelected snippet:
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) {
int position = tab.getPosition();
switch (position) {
case 0:
break;
case 1:
break;
case 2:
break;
}
}
Part of MainActivity that matters here:
public class MainActivity extends ActionBarActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Novice", "Članki", "O Tribuni" };
@Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getSupportActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(android.app.ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
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) {
}
});
}
Any help / suggestion appreciated.
OK, I figured it out by myself guys.
The answer is to notify the viewPager
about the TabSelected.
Use this line of code in your onTabSelected
method:
mViewPager.setCurrentItem(tab.getPosition());
Hope it helps someone else too!
