In my example code i have three Swipeable Tabs in MainActivity.java namely : Android, IOS and WINDOWS and i am using swipe to switch between Tabs.
Now, i have to implement PageTransformer with Swipeable Tabs, so here i need your help, is it possible, if yes so how ?
MainActivity.java:-
public class MainActivity extends FragmentActivity {
ViewPager Tab;
TabPagerAdapter TabAdapter;
ActionBar actionBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabAdapter = new TabPagerAdapter(getSupportFragmentManager());
Tab = (ViewPager)findViewById(R.id.pager);
Tab.setOnPageChangeListener(
new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar = getActionBar();
actionBar.setSelectedNavigationItem(position);
}
});
Tab.setAdapter(TabAdapter);
..............
}
}
Here is what i want to implement in my program :
and this is how my Tab looks :
I found my solution here, its really easy to implement
Usage is pretty straightforward, just attach a PageTransformer to the ViewPager:
viewpager.setPageTransformer(false, new ViewPager.PageTransformer() {
@Override
public void transformPage(View page, float position) {
// do transformation here
}
});
rotates the pages around their Z axis by 30 degrees; you don’t need to normalize for this one. The effect is similar to the cover flow UI pattern:
@Override
public void transformPage(View page, float position) {
page.setRotationY(position * -30);
}
so here is my final code, which i used:
viewPager = (ViewPager)findViewById(R.id.pager);
viewPager.setOnPageChangeListener(
new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
actionBar = getActionBar();
actionBar.setSelectedNavigationItem(position);
}
});
viewPager.setAdapter(tabAdapter);
viewPager.setPageTransformer(false, new PageTransformer() {
public void transformPage(View page, float position) {
page.setRotationY(position * -30); // animation style... change as you want..
}
});
