android detect no movement

Question

I'm using motion event, action_down, action_move etc, to detect when there is no finger movement but the finger is still on the screen. For instance, the user moves in a vertical line from top of the screen to the bottom and then stops movement without lifting the finger. How do I detect when there is no movement but the finger is still on the screen after the drag/swipe?

EDIT: What I'm trying to do is count every time I change direction of movement in a vertical direction. And to do that I'm trying to detect when I stop movement against the change of movement. For instance, I move down the screen and then move back up, that counts as two counts. Here is my code, please don't provide me with code as a direct answer but hints or clues so that I can try and figure it out myself (my code might look a bit confusing, I'm just trying out different things):

@Override public boolean onTouchEvent(MotionEvent event) {

    switch (event.getAction()) {
    case MotionEvent.ACTION_DOWN:

        oldX = event.getX();
        oldY = event.getY();

        oldSpeedY = System.currentTimeMillis();
        break;

    case MotionEvent.ACTION_MOVE:
        posY = event.getY();
        posSpeedY = System.currentTimeMillis();

        float timeElapsed = (posSpeedY - oldSpeedY) / 1000;
        float diffSpeed = posSpeedY - oldSpeedY;
        if (changeOfMovement(posY, oldY)) {
        //if (diffSpeed == 0)
            count += 1;


        }

        break;

    case MotionEvent.ACTION_UP:

        // count seconds here
        break;

    }

    Toast.makeText(getApplicationContext(), "Swipe: " + count,
            Toast.LENGTH_SHORT).show();

    return false;

}

public boolean changeOfMovement(float posY, float oldY) {

    int newY = Math.round(posY);
    double distance = Math.abs(newY - oldY);

    oldY = newY;
    //float speed = (float) (distance / time);
    //if (distance < 25)
        //return false;
    //if (speed == 0)

        //return true;

    if (distance < 25)

        return true;

    return false;
}

Answer 1

The finger touches the screen until you receive either of the MotionEvent actions ACTION_UP or ACTION_CANCEL

Answer 2

The ACTION_DOWN Event is still valid until the finger is lifted from the screen or you can wait till a ACTION_UP Event is detected

Answer 3

I'm not sure if my situation is like yours, but mine I was want to detect if the user stopped moving inside circle within one second and starts moving again, by comparing between last two currentTimeMillis.

So, what I've done is I initialized fixed ArrayList to save the last two times in move event:

public class FixedArrayList extends ArrayList {
    int fixedSize = 10;

    public FixedArrayList(){}

    public FixedArrayList(int fixedSize){
        this.fixedSize = fixedSize;
    }

    @SuppressWarnings("All")
    public void addItem(Object object){
        if(size() < fixedSize){
            add(object);
        } else{
            remove(0);
            add(object);
        }
    }
}

Now, I've initialized my new class with fixed 2 items to be saved:

    FixedArrayList savedLastMove = new FixedArrayList(2); 
    int secondsToWait = 1;
    public boolean onTouchEvent(MotionEvent event) {
    int action = MotionEventCompat.getActionMasked(event);
    switch (action) {
        case (MotionEvent.ACTION_MOVE):
            currentSystemTime = TimeUnit.MILLISECONDS.toSeconds(System.currentTimeMillis());
            savedLastMove.addItem(currentSystemTime);
            if(savedLastMove.size() >= 2 && ((long)savedLastMove.get(1) - (long)savedLastMove.get(0)) >= secondsToWait){
               //Do what you want after secondsToWait
            }
        return true;
    }

I hope that will help! Because it solved my problem.
