last point also rendering for actor in libgdx - libgdx

Question

I am new to lib gdx and facing problem of proper rendering. While I am moving Actor , it is moving fine but last position frame is not cleared from screen , so whole path is appearing while moving .
It is like if object 1 move then it appear like 11111111111111111111111111111 while it should be only at last point like 1.
My actor
public class SinglePipe extends Actor {
#Override
public void draw(SpriteBatch batch, float parentAlpha) {
batch.setColor(getColor().r, getColor().g, getColor().b, getColor().a);
batch.draw(Assets.car, this.getX(), this.getY());
}
#Override
public void act(float delta) {
// TODO Auto-generated method stub
super.act(delta);
}
}
Screen class
public class GameScreen implements Screen, GestureListener {
private Stage stage;
private SinglePipe singlePipe;
Logger logger = new Logger("");
public GameScreen() {
// Gdx.graphics.setContinuousRendering(false);
logger.setLevel(5);
stage = new Stage();
singlePipe = new SinglePipe();
stage.addActor(singlePipe);
}
#Override
public void render(float delta) {
// camera.update();
handleInput();
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL10.GL_GREEN_BITS);
stage.act();
// stage.draw();
}
private void handleInput() {
if (Gdx.input.isKeyPressed(Input.Keys.A)) {
// singlePipe.addAction(Actions.moveBy(5, 5));
// singlePipe.addAction(Actions.rotateBy(180));
singlePipe.setX(singlePipe.getX() + 5);
singlePipe.setY(singlePipe.getY() + 5);
}
}
}

In your render method use:
Gdx.gl.glViewport(0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);`
