How to hide the onscreen keyboard when a DialogFragment is canceled by the setCanceledOnTouchOutside event

Question

If an edittext is currently focused and the user clicks outside of the DialogFragment; I want the on screen keyboard to disappear. I can get it to work for when the DialogFragment is dismissed this way:

InputMethodManager imm;
public View onCreateView(LayoutInflater inflator, ViewGroup container,
        Bundle savedInstanceState) {
imm = (InputMethodManager)getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
...}

@Override 
public void dismiss(){
    imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
    super.dismiss();
}

However, if I try the same thing for when it is canceled by touching outside of the dialogfragment, it will not work. I am trying to do this by overriding onCancel like so:

@Override
public void onCancel(DialogInterface dialog){
    imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
    super.onCancel(dialog);
}

The function is called when the outside touch event happens, but the keyboard is not removed.

I was able to solve the same problem by sub-classing the dialog and hiding the keyboard before the cancel code on the dialog was executed.

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = new Dialog(getActivity(), getTheme()) {
        @Override public void cancel() {
            if (getActivity() != null && getView() != null) {
                InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getView().getWindowToken(), 0);
            }
            super.cancel();
        }

    };
    return dialog;
}

I tried many alternate approaches including using the DialogFragment's onCancel and onDimiss listeners to no avail. I believe the issue is that the listeners are called asynchronously while the dismiss/cancel is handled synchronously; so by the time your listener is called to hide the keyboard, the window token no longer exists.

This is what I did to get this to finally work... I needed to not use the widget for the keyboard... but use the currentfocus to get the windowtoken to remove the keyboard when a user selected something outside the dialog...

@Override
public void onStop() {
    // make sure the keyboard goes away when the user selects something outside the view (cancelled outside)
    if( Utilities.isValidActivity(this.getActivity())) {
        InputMethodManager imm = (InputMethodManager)this.getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        // not the search view but the current focus at this point
        imm.hideSoftInputFromWindow(this.getActivity().getCurrentFocus().getWindowToken(), 0);                          
    }
    super.onStop();
}

I had the same issue and solved it by putting this in the AndroidManifest under the activity where I spawn the DialogFragment:

android:windowSoftInputMode="stateHidden"

Try adding an onDismissListener like this.

dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {

        @Override
        public void onDismiss(DialogInterface dialog) {
            // TODO Auto-generated method stub
            dismiss();
            }
        });
