how to move player by 1 tile libgdx

I'm using tiled in libgdx. I'm doing a top down rpg similar to final fantasy 1, 2, etc.

I use setX(getX() + velocity.x * delta); and setY(getY() + velocity.y * delta); to move the player around the map. how can i make the player move tile by tile. and How will I check what tile is the player in? can someone help me. thankyou.

I found this : 

void update()(
// Getting the target tile
if ( rightArrowPressed ) {
    targetX = (int)(currentX + 1); // Casting to an int to keep 
                                   // the target to next tile
}else if ( leftArrowPressed ){
    targetX = (int)(currentX - 1);
}

// Updating the moving entity
if ( currentX < targetX ){
    currentX += 0.1f;
}else if ( currentX > targetX ){
    currentX -= 0.1f;
}

}

from : libGDX: How to implement a smooth tile / grid based game character movement?

but I can seem to see away to implement it in my game.

I am programming a 2048 game and what i did to move the player is to have two x variables and two y variables, one for the coordinates as pixels on screen and other as in grid. when move is executed, i change the grid variable and have my gameloop checking if the grid x and y variable multiplied by the grid size equals the screen x and y variable. if it doesn't match, i then move the player.

int x, y;//Grid
int xx, yy;//Screen
int GridSize = 3;

public void tick(){
    if(x * GridSize > xx){
        xx ++;
    }        
    if(x * GridSize < xx){
        xx --;
    }
    if(y * GridSize > yy){
        yy ++;
    }
    if(y * GridSize < yy){
        yy --;
    }
}

To check what tile the player is in, you just need to do getX and getY to find the tile coordinates of the player.
