Handle back pressed to not dismiss activity

Question

I want to handle back press like whatsapp where while typing if user presses back the keyboard is dismissed and if the user presses back again ,we go to chats tab.In my activity I want that when the user presses back while typing the keyboard dismisses and some UI elements are handled.I tried handling that in the onBackPressed() method , but it isn't working and the activity is killed.

     edittext.setOnEditorActionListener (
                    new EditText.OnEditorActionListener () {
                        @Override
                        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                            if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                                    actionId == EditorInfo.IME_ACTION_DONE ||
                                    event != null &&
                                            event.getAction () == KeyEvent.ACTION_DOWN &&
                                            event.getKeyCode () == KeyEvent.KEYCODE_ENTER) {
                                if (event == null || !event.isShiftPressed ()) {
                                    // the user is done typing.

                                    View view1 = getCurrentFocus ();
                                    imm.hideSoftInputFromWindow (view1.getWindowToken (), 0);

                                    Log.e (TAG, "TYPING DONE ");
                                    result = tv_result.getText ().toString();

                                    return true; // consume.
                                }
                            }
                            return false; // pass on to other listeners.
                        }
                    }
            );

the onBackPressed() code

     @Override
    public void onBackPressed() {

    tv_result.setText("Some text");

}

dismissing keyboard is default behavior of Android, so, to investigate the error, we need to see your code — hasbi, Apr 12 '18 at 12:31
@hasbi said right its auto behavior while backpress 1st keyboard hide after that activity. I think you need to save editText data while activity destroy right? while user come back to chat screen its shows old typed text right? — Adil, Apr 12 '18 at 13:44

Since you haven't provided any code, and I can't comment yet, I will assume you're letting the onBackPressed do what it per default does, meaning that in your onBackPressed() method you have super.onBackPressed(); , removing that line should solve the issue

Edit Since you've updated your question with code, whatever is written after super.onBackPressed() will not be seen visually, as super.onBackPressed() goes back to the previous activity. Remove super.onBackPressed(), and handle the second back press with and if else statement

I removed the `super.onBackPressed();` ,but still the problem is we press back to dismiss the keyboard and then again press back and here the UI is changed .I want when the keyboard is dismissed on back pressed , the Ui should be handled here – Neha Apr 12 '18 at 12:51
I added the if statement and handled it .@Omar thanks a lot for your answer. – Neha Apr 12 '18 at 13:03

If it's on activity, onBackPressed() function do the following,

// hide virtual keyboard
            InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(m_txtSearchText.getWindowToken(), 
                                      InputMethodManager.RESULT_UNCHANGED_SHOWN);
