[Android] ViewPager.OnPageChangeListener() deprecated 에 따른 대체 메소드 addOnPageChangeListener() 사용하기
VierPager 클래스의 OnPageChangeListener()메소드가 deprecated되었다. 그리고 addOnPageChangeListener()메소드가 추가되었다. 사용법은 동일하다. 메소드명만 변경되었다고 해도 될 정도로……..
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager viewPager = findViewById(R.id.viewpager);
}
[AS-IS]
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
getSupportActionBar().setTitle(fragmentViewPagerAdapter.getPageTitle(position));
}
@Override
public void onPageSelected(int position) {
getSupportActionBar().setTitle(fragmentViewPagerAdapter.getPageTitle(position));
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
[TO-BE]
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
getSupportActionBar().setTitle(fragmentViewPagerAdapter.getPageTitle(position));
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
