I want to switch from an empty activity to a Tabbed Layout activity. I used intent but it's not working, app keeps crashing. I am using a button in my main activity from where I want to jump to a LeaderBoards named tabbed activity. How to do that?
This button in main Activity:
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent=new Intent(game4x4.this, LeaderBoards.class);//game4x4 is the main activity
startActivity(intent);
}
});
Tabbed Activity Class:
public class LeaderBoards extends AppCompatActivity {
TabLayout tabLayout;
ViewPager viewPager;
int page=1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_leader_boards);
viewPager=(ViewPager)findViewById(R.id.viewpager);
viewPager.setAdapter(new CustomAdapter(getSupportFragmentManager(),getApplicationContext()));
viewPager.setCurrentItem(page);
tabLayout=(TabLayout)findViewById(R.id.tablayout);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener()
{
@Override
public void onTabSelected(TabLayout.Tab Tab)
{
viewPager.setCurrentItem(Tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab Tab)
{
viewPager.setCurrentItem(Tab.getPosition());
}
@Override
public void onTabReselected(TabLayout.Tab Tab)
{
viewPager.setCurrentItem(Tab.getPosition());
}
});
}
private class CustomAdapter extends FragmentPagerAdapter
{
private String fragments[]= {"MyScore","TopScores"};
public CustomAdapter(FragmentManager supportFragmentManager, Context applicationContext)
{
super(supportFragmentManager);
}
@Override
public Fragment getItem(int position) {
switch (position)
{
case 0:
return new Fragment1();
case 1:
return new Fragment2();
default:
return null;
}
}
@Override
public int getCount() {
return fragments.length;
}
@Override
public CharSequence getPageTitle(int position)
{
return fragments[position];
}
}
}
Fragemt1 and Fragment2 are classes for different tabs.
