更改页面标题和片段 Android
Change the title of the page along with the fragment Android
我认为问题在于:
{
..
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
..
this.setTitle("Home");
}
和:
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
Home home = new Home();
return Home;
case 1:
Mail mail = new Mail();
return mail;
default:
return null;
}
}
我现在想显示新的 Fragment setTitle
来代替页面标题
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
Home home = new Home();
this.setTitle("change");
return Home;
case 1:
Mail mail = new Mail();
this.setTitle("change");
return mail;
default:
return null;
}
我知道那是不正确的,但我不知道正确的语法是什么我整天都在努力解决,但一无所获。
我只想更改标题。
final ArrayList<String> arrayList = new ArrayList<>();
arrayList.add("Menu1");
arrayList.add("Menu2");
arrayList.add("Menu3");
arrayList.add("Menu4");
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
getSupportActionBar().setTitle(arrayList.get(position));
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
// TODO Auto-generated method stub
}
@Override
public void onPageScrollStateChanged(int pos) {
// TODO Auto-generated method stub
}
});
