如何通过短信共享ViewPager字符串或文本

Question

我设计了一个android应用程序。我遇到了问题。我在列表视图中显示字符串，当用户单击列表视图时，字符串在ViewPager中显示。我想通过短信分享我的字符串或文本。当我单击“共享”按钮时，字符串始终共享在第一单击位置文本中。我滑动了viewpager页面，它会更改当前位置文本，但不会更改可共享文本。

Main_Activity上的ListView：

public class MainActivity extends FragmentActivity {

    PagerFragment pagerFragment;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        final ArrayList<PageData> data = new ArrayList<PageData>();
        data.add(new PageData("1", R.drawable.store, "Picture 1 jsdj kjdkjk kjk kalskfj sk ksjfksj kjfksjfk "));
        data.add(new PageData("2", R.drawable.home, "Picture 2"));
        data.add(new PageData("3", R.drawable.help, "Picture 3"));
        data.add(new PageData("4", R.drawable.ic_launcher_background, "Picture 4"));
        
        final ListView lv = (ListView) findViewById(R.id.list_view);
        final ListViewAdapter lva = new ListViewAdapter(this, R.layout.item_list, data);
        lv.setAdapter(lva);
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

               final String Category = "Hello Nasir";
               final int positionview = lv.getPositionForView(view);

                    PagerFragment pagerFragment = new PagerFragment();
                    Bundle bundle = new Bundle();
                    bundle.putInt("CURRENT_POSITION", positionview);
                    bundle.putParcelableArrayList("DATA_LIST", data);
                    bundle.putString("Category", Category);
                    pagerFragment.setArguments(bundle);
                    FragmentManager fragmentManager = getSupportFragmentManager();
                    FragmentTransaction ft = fragmentManager.beginTransaction();
                    ft.replace(R.id.container, pagerFragment, "swipe_view_fragment").commit();

                }
                
        });

    }

    @Override
    public void onBackPressed() {
        FragmentManager fm = getSupportFragmentManager();
        Fragment f = fm.findFragmentByTag("swipe_view_fragment");
        if (f != null) {
            fm.beginTransaction().remove(f).commit();
        } else {
            super.onBackPressed();
        }
    }
    
}

ViewPager：

public class PagerFragment extends Fragment{

    private List<PageData> data;
    private int currentPosition;

    
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_pager, container, false);
        final ViewPager mViewPager = v.findViewById(R.id.pager_view);

        currentPosition = getArguments().getInt("CURRENT_POSITION");
        data = getArguments().getParcelableArrayList("DATA_LIST");

        ImageButton share = v.findViewById(R.id.share);
        share.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent sharingIntent = new Intent(Intent.ACTION_SEND);
                sharingIntent.setType("text/plain");
                String shareString =  data.get(currentPosition).getTitle();
//                String shareString =  mViewPager.setCurrentItem(mViewPager.getCurrentItem() + 1).;
                sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareString);
                startActivity(Intent.createChooser(sharingIntent, "Share Application Via"));
            }
        });
        
        FragmentItemPagerAdapter fragmentItemPagerAdapter = new FragmentItemPagerAdapter(getFragmentManager(), data);
        mViewPager.setAdapter(fragmentItemPagerAdapter);
        mViewPager.setCurrentItem(currentPosition);
        return v;
    }

}

ViewPagerAdapter：

public class FragmentItemPagerAdapter extends FragmentStatePagerAdapter {
    private List<PageData> data;


    public FragmentItemPagerAdapter(FragmentManager fm, List<PageData> data) {
        super(fm);
        this.data = data;
    }

    @Override
    public Fragment getItem(int position) {
        Fragment fragment = new PageFragment();
        Bundle args = new Bundle();
        args.putString(PageFragment.COUNT, data.get(position).getCount());
        args.putString(PageFragment.TITLE, data.get(position).getTitle());
        args.putInt(PageFragment.PICTURE, data.get(position).getPicture());
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    public static class PageFragment extends Fragment {
        public static final String COUNT = "count";
        public static final String TITLE = "title";
        public static final String PICTURE = "picture";

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_item, container, false);

            TextView title = rootView.findViewById(R.id.item_label);
            title.setText(getArguments().getString(TITLE));

            ImageView Picture =  rootView.findViewById(R.id.image_view);
            Picture.setImageResource(getArguments().getInt(PICTURE));

            TextView count = rootView.findViewById(R.id.Nasir);
            count.setText("SMS : " + getArguments().getString(COUNT) + " of 20");

            return rootView;
        }


    }
}
