将变量从 ViewPager 传递到 Clicklistener [重复]

Question

如何将ViewPager.OnPageChangeListener() 的实际位置获取到OnClickListener：

@Override
public View onCreateView(LayoutInflater inflater, final ViewGroup container, Bundle savedInstanceState) {

    btnDL.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // I need the "int posistion" here

        } 
    });
}

所以这是OnPageChangeListener：

private void setCurrentItem(int position) {
    viewPager.setCurrentItem(position, false);
    displayMetaInfo(selectedPosition);
}

//  page change listener
ViewPager.OnPageChangeListener viewPagerPageChangeListener = new  
ViewPager.OnPageChangeListener() {

    @Override
    public void onPageSelected(int position) {
        displayMetaInfo(position);

        // I need this position in my OnClickListener
    }
}

谢谢！

使用这个

@Override
   public View onCreateView(LayoutInflater inflater, final ViewGroup
   container,
                         Bundle savedInstanceState) {

    btnDL.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            int pos = viewPager.getCurrentItem();
    } });
