Question

我有三个视图在滑动片段与调查问题有动态radiobuttons（所有视图的布局是相同的，我只是重复）。我可以从一个屏幕获取所选无线电按钮的数据，但是如何从所有屏幕获取所有选定无线电按钮的数据？以下是我的工作代码

enter image description here

FragmentActivity.java

public class MainActivity extends FragmentActivity {
     static final int ITEMS = 3;
     MyAdapter mAdapter;
     ViewPager mPager;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.fragment_pager);
     mAdapter = new MyAdapter(getSupportFragmentManager());
     mPager = (ViewPager) findViewById(R.id.pager);
     mPager.setAdapter(mAdapter);

     Button button = (Button) findViewById(R.id.first);
     Button submitaldatabutton = (Button) findViewById(R.id.first);
     button.setOnClickListener(new OnClickListener() {
     public void onClick(View v) {
     mPager.setCurrentItem(0);
     }
     });

     button = (Button) findViewById(R.id.last);
     button.setOnClickListener(new OnClickListener() {
     public void onClick(View v) {
     mPager.setCurrentItem(ITEMS - 1);
     }
     });

     submitaldatabutton = (Button) findViewById(R.id.submitalldata);
     submitaldatabutton.setOnClickListener(new OnClickListener() {
         public void onClick(View v) {

             //Get all data

     }
     });

     }

     public static class MyAdapter extends FragmentStatePagerAdapter {
     public MyAdapter(FragmentManager fragmentManager) {
     super(fragmentManager);
     }

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

    @Override
    public Fragment getItem(int position) {
        // TODO Auto-generated method stub
        switch (position) {
         case 0: // Fragment # 0 - This will show image
         return LayoutFragment.init(position);
         case 1: // Fragment # 1 - This will show image
         return LayoutFragment.init(position);
         default:// Fragment # 2-9 - Will show list
         return LayoutFragment.init(position);
         }
    }

     //@Override
     /*public Fragment getItem(int position) {
     switch (position) {
     case 0: // Fragment # 0 - This will show image
     return ImageFragment.init(position);

     return ImageFragment.init(position);
