How to hide soft input Keyboard when the Navigation drawer is being toggled , using fragments

Question

So i have A navigation Drawer in the MainActivity and when a child of the expandable List View is being clicked the content is presented in a fragment. Inside the fragment i have a Menu icon , when clicked a search textbox is being displayed and the soft input Keyboard. but if someone push the toggle button to open the navigation drawer the soft input keyboard doesn't disappear. I have tried this methods :

First method: closing keyboard from MainActivity from onDrawerClosed ,using this code, nothing happened :

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

Second method : closing the Keyboard from MainActivity from the method onOptionsItemSelected(MenuItem item) , getting the item id and writing the same code as previous in the case : android.R.id.home, nothing happened

Third method : As the previous method but within the Fragment writing the above code, nothing happened :

  InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Service.INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(ed_search.getWindowToken(), 0);

The soft Input Keyboard opens from the Fragment so i can't use something like the code in the above line because the ed_search is declared in the Fragment.

This is the code from the Main Activity:

public class MainActivity extends AppCompatActivity {

private static DrawerLayout mDrawerLayout;
private static ExpandableListView mExpandableListView;
private ActionBarDrawerToggle mActionBarDrawerToggle;
private Toolbar mToolbar;

//nav drawer Title

Answer 1

I had a similar situation wherein I had search in the child fragment of the navigation drawer.

Now on searching the keyboard would pop up and when I wanted to click on the navigation drawer again the keyboard wouldn't hide so I mixed up the 2 solution above and came up with this.

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.app_name, R.string.app_name) {

@Override
    public void onDrawerSlide(View drawerView, float slideOffset){
        hideKeyboard(true, ActivityName);
        }
};

public static void hideKeyboard(boolean val, Activity activity) {
    View view;
    view = activity.getWindow().getCurrentFocus();
        if (val == true) {
            InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
        }
    }

and guess what this worked! thanks for your help!

Answer 2

use this

 public static void showKeyboard(Activity pActivity, View pView) {
    if (pView == null) {
        pView = pActivity.getWindow().getCurrentFocus();
    } else {
        /**
         * For {@link EditText}, a call to {@link View#requestFocus()} will
         * open the keyboard as per inputType set for {@link EditText}
         */
        pView.requestFocus();
    }
    if (pView != null) {
        InputMethodManager imm = (InputMethodManager) pActivity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            imm.showSoftInput(pView, InputMethodManager.SHOW_FORCED);
        }
    }
}


public static void hideKeyboard(View pView, Activity pActivity) {
    if (pView == null) {
        pView = pActivity.getWindow().getCurrentFocus();
    }
    if (pView != null) {
        InputMethodManager imm = (InputMethodManager) pActivity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            imm.hideSoftInputFromWindow(pView.getWindowToken(), 0);
        }
    }
}
