How to programmatically scroll a recyclerview over keyboard?

I have a recyclerview in which there is an edit text where it will hidden and opens up on click of some button. Please refer to screen 1.

On click of reject or accept the view is displayed:

Now, my recyclerview is expanding downwards but I want it to expand upward like this:

By default, it expands downward:

I want it to expand upward like this:

Similarly, when keyboard opens up I want the whole recyclerview cell just above the keyboard like this.

By default, it does not move upward:

I want something like this:

What should be the approach for this functionality?
Do I have to do the calculations of cell height, keyboard height or is there some other method for this.

Please attach related links.
Thanks

I wrote this for my chat class you can rewrite this code snippet according to yours.

private boolean keyboardShown(View rootView) {

    final int softKeyboardHeight = 100;
    Rect r = new Rect();
    rootView.getWindowVisibleDisplayFrame(r);
    DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
    int heightDiff = rootView.getBottom() - r.bottom;
    return heightDiff > softKeyboardHeight * dm.density;
}

messageEditText.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            if (keyboardShown(messageEditText.getRootView())) {
                Log.d("keyboard", "keyboard UP");

                if (keyboardUp == false) {
                    if (results.size() > 0)
                        chatList.smoothScrollToPosition(results.size()+1);
                    keyboardUp = true;
                }

            } else {
                Log.d("keyboard", "keyboard Down");
                keyboardUp = false;
            }
        }
    });

Let's divide the question into two, scroll down the RecyclerView and show the cell when the keyboard is shown.

  1. just use the scrollToPosition(index) with to the cell index

  2. you can just change the android:windowSoftInputMode to be adjustSize in the activity:

    <activity
android:windowSoftInputMode="adjustResize"
android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

or just in the fragment:

        window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)
