notifyDataSetChanged和键盘 [英] notifyDataSetChanged and keyboard

问题描述

当我调用pagerAdapter.notifyDataSetChanged();时为什么隐藏键盘???我正在使用 https://github.com/romannurik/Android-WizardPager .该库使用ViewPager.并且当我调用notifyDataSetChanged并且软件键盘可见时，键盘隐藏.

Why keyboard hiding when I call pagerAdapter.notifyDataSetChanged(); ?? I'm using https://github.com/romannurik/Android-WizardPager . This library using ViewPager. And when i call notifyDataSetChanged and software keyboard is visible, keyboard hiding.

public class WizardAdapter extends FragmentStatePagerAdapter {

        private int cutOffPage = -1;
        private BaseFragment primaryItem;

        public WizardAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int i) {
            return pages.get(i).createFragment();
        }

        @Override
        public int getItemPosition(Object object) {
            if (object instanceof WizardFragment) {
                Page page = ((WizardFragment) object).getData();
                if (!pages.contains(page)) {
                    return POSITION_NONE;
                }
            }

            if (object == primaryItem) {
                // Re-use the current fragment (its position never changes)
                return POSITION_UNCHANGED;
            }

            return POSITION_NONE;
        }

        @Override
        public void setPrimaryItem(ViewGroup container, int position, Object object) {
            super.setPrimaryItem(container, position, object);

            primaryItem = (BaseFragment) object;
        }

        @Override
        public int getCount() {
            int count = 0;

            if (cutOffPage >= 0) {
                count = Math.min(cutOffPage + 1, pages.size());
            } else if (pages != null) {
                count = pages.size();
            }

            return count;
        }

        public int getCutOffPage() {
            return cutOffPage;
        }

        public void setCutOffPage(int cutOffPage) {
            this.cutOffPage = cutOffPage;
        }
    }

推荐答案

尝试一下，这应该可行

//Import this
import android.view.inputmethod.InputMethodManager;

//Create object
private InputMethodManager imm;

imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, InputMethodManager.HIDE_IMPLICIT_ONLY);
