java - 无法在我的 Activity 中调用类

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;
    }


}

现在我尝试通过以下方式在我的 Activity 的 ScreenSlidePagerAdapter 中调用它:

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 无法解析为变量

我在这里错过了什么？我知道我指的是错误的类(class)，但我找不到解决它的方法。谁能给我一点线索？

Answer 1

试试这个

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

到

final SayingsHolder holder = (SayingsHolder)getApplication();
