Question

我的应用中有一个sectionpager，想要从字符串资源加载其标题，以支持不同的语言标题。
这是我的sectionpager课程：

public class SectionsPagerAdapter extends FragmentPagerAdapter {

public SectionsPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int position) {
    switch (position) {
    case 0:
        Auftrag fragmenttab1 = new Auftrag();
        return fragmenttab1;
    case 1:
        Email fragmenttab2 = new Email();
        return fragmenttab2;
    case 2:
        Fragen fragmenttab3 = new Fragen();
        return fragmenttab3;
    case 3:
        Statistik fragmenttab4 = new Statistik();
        return fragmenttab4;
    }
    return null;
}
@Override
public int getCount() {
    return 4;
}
@Override
public CharSequence getPageTitle(int position) {

    switch (position) {
    case 0:
        return Resources.getSystem().getString(R.string.questions);
    case 1:
        return Resources.getSystem().getString(R.string.emails);
    case 2:
        return Resources.getSystem().getString(R.string.calls);
    case 3:
        return Resources.getSystem().getString(R.string.orders);
    }
    return null;
}
}

这是我得到的错误：

我认为应该是这样的：

getResources().getString(R.string.my_string);
