}  @override public void render(float delta) {     gdx.gl.glclearcolor(0.09f, 0.28f, 0.2f, 1);     gdx.gl.glclear(gl10.gl_color_buffer_bit);      stage.act(delta);     stage.draw();      batch.begin();     batch.end(); }  @override public void resize(int width, int height) {     if (stage == null)         stage = new stage(width, height, true);     stage.clear();      gdx.input.setinputprocessor(stage);       /**      * quit button      */      textbuttonstyle stylequit = new textbuttonstyle();     stylequit.up = skin.getdrawable("8layer");     stylequit.down = skin.getdrawable("8layer");      quit = new button(stylequit);     quit.setwidth(854);     quit.setheight(480);      quit.addlistener(new inputlistener() {         public boolean touchdown(inputevent event, float x, float y,                 int pointer, int button) {             return true;         }          public void touchup(inputevent event, float x, float y,                 int pointer, int button) {          }     });      /**      * end quit button      */       /**       * store button       */      textbuttonstyle stylestore = new textbuttonstyle();

            game.setscreen(new gamescreen(game));         }     });      /**      * end play button      */      /**      * start background      */      textbuttonstyle stylemenu = new textbuttonstyle();

    stage.addactor(play);     //stage.addactor(option);     //stage.addactor(store);     //stage.addactor(custom);     //stage.addactor(quit);  }  @override public void show() {     audio.playmusic(true);     batch = new spritebatch();     atlas = new textureatlas("data/mainmenu/mainmenu.pack");     skin = new skin();     skin.addregions(atlas); }  @override public void hide() {     dispose(); }  @override public void pause() {  }  @override public void resume() {  }  @override public void dispose() {     batch.dispose();     skin.dispose();     atlas.dispose();     stage.dispose();     audio.dispose(); } 

}

1. create table object.
2. add buttons it.
3. add table object stage.

hope helps. luck.
