Support Immersive mode when displaying DialogFragment dialog

Question

I have an android application that is created using fragments

I hide the bars above and below the screen using the following code.

 @Override
protected void onResume() {
    super.onResume();
    isInBackground = false;

    if(null == getFragmentManager().findFragmentById(R.id.content_container))
    {
        getFragmentManager().beginTransaction().add(R.id.content_container,new PresenterFragment(), PresenterFragment.FRAG_TAG).commit();
    }

    if(Build.VERSION.SDK_INT >=19)
    {
        View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        decorView.setSystemUiVisibility(uiOptions);
        decorView.setOnSystemUiVisibilityChangeListener(new View.OnSystemUiVisibilityChangeListener() {
            @Override
            public void onSystemUiVisibilityChange(int visibility) {
                View decorView = getWindow().getDecorView();
                int uiOptions = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
                        | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
                decorView.setSystemUiVisibility(uiOptions);
            }
        });
    }
}

When the soft keyboard is displayed, on which the stripes are displayed, I can live with it, as they hide when the keyboard deviates. However, if a fragment of the dialogue is displayed while the soft keyboard is displayed, then when both the keyboard and the fragment of the dialogue are rejected, they remain at the top of the application.

My 3 questions:

Can I stop the soft keyboard to change the user interface mode?

Can I stop the dialog box "Change dialog box"?

edit: I used below code to see if the keyboard is displayed

public static boolean isKeyBoardShown(){
    InputMethodManager imm = (InputMethodManager)currentActivity.getSystemService(Context.INPUT_METHOD_SERVICE);
    if (imm.isAcceptingText()) {
        return true;
    } else {
        return false;
    }
}
