main activity
package pl.looksok.viewpagerdemo;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyPagerAdapter pageAdapter = new MyPagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager)findViewById(R.id.myViewPager);
pager.setAdapter(pageAdapter);
}
}
main adapter page
package pl.looksok.viewpagerdemo;
import java.util.ArrayList;
import java.util.List;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class MyPagerAdapter extends FragmentPagerAdapter {
private List<Fragment> fragments;
public MyPagerAdapter(FragmentManager fm) {
super(fm);
this.fragments = new ArrayList<Fragment>();
fragments.add(new FragmentBlue());
fragments.add(new FragmentGreen());
fragments.add(new FragmentPink());
fragments.add(new image4());
fragments.add(new image5());
fragments.add(new image6());
}
@Override
public Fragment getItem(int position) {
return fragments.get(position);
}
@Override
public int getCount() {
return fragments.size();
}
}
