Answer 1

It is not possible to change the timer on the onLongClick event, it is managed by android itself.

What is possible is to use .setOnTouchListener().

Then register when the MotionEvent is a ACTION_DOWN. Note the current time in a variable. Then when a MotionEvent with ACTION_UP is registered and the current_time - actionDown time > 5000 ms then do something.

so pretty much:

Button button = new Button();
long then = 0;
    button.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_DOWN){
                then = (Long) System.currentTimeMillis();
            }
            else if(event.getAction() == MotionEvent.ACTION_UP){
                if(((Long) System.currentTimeMillis() - then) > 5000){
                    // 5 second of long click
                    return true;
                }
            }
            return false;
        }
    })

you can use Handler like this way:

Button b=findViewById(R.id.btn);

    final Runnable run = new Runnable() {

        @Override
        public void run() {
            Toast.makeText(MainActivity.this, "clicked", Toast.LENGTH_SHORT).show();
            // Your code to run on long click

        }
    };
    final Handler handel = new Handler();
    b.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            switch (arg1.getAction()) {
                case MotionEvent.ACTION_DOWN:
                    handel.postDelayed(run, 5000/* OR the amount of time you want */);
                    break;

                default:
                    handel.removeCallbacks(run);
                    break;

            }
            return true;
        }
    });
