我的考试试卷数据以下图所示的形式存储:
我正在尝试使用视图寻呼机按顺序显示此信息,但不知道该怎么做。我希望视图寻呼机在一个部分中显示所有问题,然后转到下一部分并在那里显示问题,依此类推,如果有下一部分的话。如果没有下一部分,论文就会结束。这将允许我制作具有不同部分和不同类型问题的试卷。我当前的查看分页器代码只是在一个部分显示问题,如下所示:
public class QuestionAdapter extends android.support.v13.app.FragmentStatePagerAdapter {
private int NUM_ITEMS;
public QuestionAdapter(FragmentManager fragmentManager, int num_items){
super(fragmentManager);
NUM_ITEMS = num_items;
}
@Override
public int getCount(){
return NUM_ITEMS;
}
@Override
public Fragment getItem(int position){
return QuestionContainerFragment.newInstance(position);
}
}
答案 0 :(得分:1)
你可以试试这样的......
public class QuestionAdapter extends FragmentStatePagerAdapter {
private int NUM_ITEMS;
// this is the object in which you are storing your data
private YourData yourData;
//when you initialize the adapter, send your data
public QuestionAdapter(FragmentManager fragmentManager, int num_items, YourData yourData){
super(fragmentManager);
NUM_ITEMS = num_items;
this.yourData = yourData;
}
@Override
public int getCount(){
return NUM_ITEMS;
}
@Override
public Fragment getItem(int position){
//based on position, send appropriate data to your fragment
switch(position){
case 0:
return QuestionContainerFragment.newInstance(yourData.sectionOne);
case 1:
return QuestionContainerFragment.newInstance(yourData.sectionTwo);
case 2:
return QuestionContainerFragment.newInstance(yourData.sectionThree);
....
....
....
}
}
}
在QuestionContainerFragment中,解析并显示刚刚发送的数据。
