Android 共享显示先前片段文本的ViewPager文本

我想通过共享显示在ViewPager上的TextView内容 FragmentPagerAdapter但是当我分享以前分享的内容时 聚焦文本查看内容

当我点击“共享”按钮时，它会共享上一个页面的内容 我在当前片段中所处的片段

我的代码

Share.java

public class Share extends FragmentActivity {
private MyAdapter mAdapter;
private ViewPager mPager;
static int pages=4;
Button share;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mAdapter = new MyAdapter(getSupportFragmentManager());

    mPager = (ViewPager) findViewById(R.id.vpShare);
    mPager.setAdapter(mAdapter);

    share=(Button)findViewById(R.id.btShare);
    share.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            TextView textView = (TextView) findViewById(R.id.tv);
            String string = textView.getText().toString();

            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("text/plain");
            intent.putExtra(Intent.EXTRA_TEXT, string);

            startActivity(Intent.createChooser(intent, "Share with:"));

        }
    });
}

public static class MyAdapter extends FragmentPagerAdapter {
    public MyAdapter(FragmentManager fm) {
        super(fm);
    }

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



    @Override
    public Fragment getItem(int position) {
        switch (position) {
        case 0:
            return new ShowFragment1();
        case 1:
            return new ShowFragment2();
        case 2:
            return new ShowFragment3();
        case 3:
            return new ShowFragment4();



        default:
            return null;
        }

    }
}
}

    TextView textView = (TextView) view.findViewById(R.id.tv);
    textView.setText("fragment1");

    return view;
}
}

我找到了问题的解决方案 我已将我的

Share.java

类更改如下

Share.java

public class ShareNew extends FragmentActivity {


private MyPager mPager;
static int pages = 4;
Button share;
private TextView textView;
private int i;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.viewpagerlayout);

    mPager = (MyPager) findViewById(R.id.myviewpager);


    // mPager.setAdapter(mAdapter);
    share = (Button) findViewById(R.id.btnShare);

    for (i = 0; i < pages; i++) {
        textView = new TextView(this);

        switch (i) {
        case 0:
            textView.setText(R.string.share1);
            break;
        case 1:
            textView.setText(R.string.share2);
            break;
        case 2:
            textView.setText(R.string.share3);
            break;
        case 3:
            textView.setText(R.string.share4);
            break;

        }

        textView.setTag(i);
        textView.setBackgroundColor(Color.BLUE);
        textView.setTextColor(Color.WHITE);
        textView.setTextSize(30);
        mPager.addPage(textView);

    }

}

public void onShareText(View view) {

     TextView tvShare;

     tvShare = (TextView) mPager.findViewWithTag(mPager.getCurrentItem());

    String string = tvShare.getText().toString();

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.setType("text/plain");
    intent.putExtra(Intent.EXTRA_TEXT, string);

    startActivity(Intent.createChooser(intent, "Share with:"));

}

}
