【问题描述】：

我的应用中有一个sectionpager，我想从字符串资源中加载它的标题，以支持不同的语言标题。
那是我的sectionpager 班级：

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：

【解决方案1】：

我觉得应该是这样的：

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

如需了解您收到错误的原因，请参阅this SO 帖子。

【讨论】：

它说：方法 getResources 未定义类型 Sectionpageradapter。
然后使用 context.getResources() 你的上下文必须存在类似的东西
你能给我一些关于如何正确定义上下文的提示吗？
最好的方法可能是将上下文传递给构造函数本身 Context context;//这是类变量 public SectionsPagerAdapter(FragmentManager fm,Context context) { super(fm); this.context = 上下文}
老兄，谢谢你，你拯救了我的一天。它解决了我的问题。
