? 同理，其他幾個fragment復(fù)制粘貼一下就行。

private static final int nuumber_fragment=0,family_fragment=1,colors_fragment=2,phrases_fragment=3;



public CategoryFragmentPagerAdapter(Context context ,FragmentManager manager){
super(manager);
this.context=context;
}

@Override
public Fragment getItem(int position) {
switch (position){
default:return new NumbersFragment();
case nuumber_fragment:
return new NumbersFragment();
case family_fragment:
return new FamilyFragment();
case colors_fragment:

}
}

@Override
public int getCount() {
return size;
}

@Nullable
@Override
