无法在我的活动中调用课程

Question

我有这门课：

public class SayingsHolder extends Application{

    ArrayList<String> SayingsList = new ArrayList<String>(){{
        SayingsList.add("1");
        SayingsList.add("2");

    }};

    public ArrayList<String> getSayingsList() {
        return SayingsList;
    }


}

现在我正在尝试在我的活动的ScreenSlidePagerAdapter 中通过以下方式调用它：

private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
    String[] displayText;

    final SayingsHolder holder = (SayingsHolder).getApplication();

    String names[] = {"1","2","3"};
    public ScreenSlidePagerAdapter(FragmentManager fm,String[] displayText) {
        super(fm);
        this.displayText=displayText;
    }

    @Override
    public Fragment getItem(int position) {
        System.out.println(position);
        ScreenSlidePageFragment fragment = new ScreenSlidePageFragment(); 
        fragment.setText(names[position]);
        return fragment;
    }

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

但它给了我这个错误：

SayingsHolder cannot be resolved to a variable

我在这里缺少什么？我知道我指错了班级，但我找不到解决方法。谁能给我一个小线索？

Answer 1

试试这个

final SayingsHolder holder = (SayingsHolder).getApplication();

到

final SayingsHolder holder = (SayingsHolder)getApplication();
