Programmatically Hide Soft Keyboard in ViewPager.OnPageChangeListener onPageSelected()?

Question

I have a ViewPager + ActionBar with tabs. I want to make the soft keyboard hide when I \"swipe\" to another tab but I can\'t figure out how.

I\'ve passed in my Activity

Answer 1

In my case for fragment activity following is working fine.

((CommentActivity)getActivity()).pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
     @Override
     public void onPageSelected(int position) {
         final InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
         imm.hideSoftInputFromWindow(txtComment.getWindowToken(), 0);
     }

     @Override
     public void onPageScrolled(int position, float offset, int offsetPixels) {
     }

     @Override
     public void onPageScrollStateChanged(int state) {
     }
});

UPDATE: This was my fragment activity from which two fragments(CommentFragment,AnotherFragment) are opening in a ViewPager

public class CommentActivity extends FragmentActivity {
    ViewPager pager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        pager = (ViewPager) findViewById(R.id.viewPager);
        .......
        .......
    }

    private class MyPagerAdapter extends FragmentPagerAdapter {

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

        @Override
        public Fragment getItem(int pos) {
            switch(pos) {
                case 0: return CommentFragment.newInstance();
                default: return AnotherFragment.newInstance();
            }
        }

        @Override
        public int getCount() {
            return 2;
        }       
    }

}

If keypad is appear for an EditText in CommentFragment and want to switch to AnotherFragment and want to hide keypad at the time of switch

public class CommentFragment extends Fragment  {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        .........
        .........
        .........
        ((CommentActivity)getActivity()).pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

         @Override
         public void onPageSelected(int position) {
            final InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(txtComment.getWindowToken(), 0);
         }

         @Override
         public void onPageScrolled(int position, float offset, int offsetPixels) {
         }

         @Override
         public void onPageScrollStateChanged(int state) {
         }
   });
}

Answer 2

I don't use onPageSelected() because the hide-keyboard animation screws with the swiping animation. Instead use onPageScrollStateChanged():

@Override
public void onPageScrollStateChanged(int state)
{
    if (state == ViewPager.SCROLL_STATE_IDLE)
    {
        if (mViewPager.getCurrentItem() == 0)
        {
            // Hide the keyboard.
            ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE))
                .hideSoftInputFromWindow(mViewPager.getWindowToken(), 0);
        }
    }
}

Answer 3

Simple way :

InputMethodManager imm = (InputMethodManager)    
getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

Answer 4

Common way:

private void hideVirturalKeyboard(){
View v = getCurrentFocus();
if (v != null && v instanceof EditText) {
InputMethodManager mgr = (InputMethodManager)(v.getContext().getSystemService(Context.INPUT_METHOD_SERVIC
E));
mgr.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
} 

Answer 5

In your activity, you can do the following:

mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageSelected(int position) {
        final InputMethodManager imm = (InputMethodManager)getSystemService(
            Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(mView.getWindowToken(), 0);
    }

    @Override
    public void onPageScrolled(int position, float offset, int offsetPixels) {
    }

    @Override
    public void onPageScrollStateChanged(int state) {
    }
});
