当然可以，那正是我所做的。
public interface FFListener{ public void onClick(FFListenerButton flb);}和
public class FFListenerButton extends FFButton{ private FFListener ffListener; public FFListenerButton(Rectangle bounds, CharSequence text, FFListener ffListener) { super(bounds, text); this.ffListener = ffListener; } @Override protected void action() { ffListener.onClick(this); }}和
public abstract class FFButton { private Rectangle bounds; private CharSequence text; private boolean selected; private boolean hidden; private boolean active; private boolean disabled; public FFButton(Rectangle bounds, CharSequence text) { this.bounds = bounds; this.text = text; this.hidden = false; this.active = false; this.disabled = false; } protected abstract void action(); public void execute() { if(disabled == false) { action(); } } public boolean contains(float x, float y) { return bounds.contains(x, y); } public float x() { return bounds.x; } public float y() { return bounds.y; } public float width() { return bounds.width; } public float height() { return bounds.height; } public void drawBounds(ShapeRenderer shapeRenderer) { if(hidden != true) { shapeRenderer.rect(x(), y(), width(), height(), 0, 0, 0); } } public CharSequence getText() { return text; } public FFButton setText(String text) { this.text = text; return this; } public void drawText(SpriteBatch batch) { if(hidden != true) { Resources.bitmapFont.draw(batch, getText(), x()+(width()/8), y()+height()*0.75f); //black magic, please adjust } } public boolean getSelected() { return selected; } public FFButton setSelected(boolean selected) { this.selected = selected; return this; } public boolean isActive() { return active; } public FFButton setActive(boolean active) { this.active = active; return this; } public boolean isHidden() { return hidden; } public FFButton setHidden(boolean hidden) { this.hidden = hidden; return this; } public Rectangle getBounds() { return bounds; } public boolean isDisabled() { return disabled; } public void setDisabled(boolean disabled) { this.disabled = disabled; }}尽管从技术上讲，这使用Rectangle并使用ShapeRenderer进行渲染，但将它换成Sprite确实不难。之后，您可以仅询问with包含单击是否包含单击，然后从外部调用execute（）。
像这样创建：
backButton = new FFListenerButton(new Rectangle(400, 20, 60, 30), "Back", this);
并处理如下事件：
@Overridepublic void onClick(FFListenerButton clb){ if(clb == backButton) { backButtonPressed(); } else if(clb == selectButton) { ... }}这使用我的AbstractMenuScreen类将事件委托给按钮（如果被单击）：
public abstract class AbstractMenuScreen extends baseScreen{ protected List<FFButton> buttons; public AbstractMenuScreen(List<FFButton> buttons) { this.buttons = buttons; } @Override public void render(float delta) { Gdx.gl.glClearColor(0, 0, 0, 1); Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); Resources.batch.setProjectionMatrix(Resources.normalProjection); Resources.batch.begin(); for(int i = 0; i < buttons.size(); i++) { FFButton b = buttons.get(i); if(b.isHidden() != true) { b.drawText(Resources.batch); } } Resources.batch.end(); Resources.shapeRenderer.setColor(Color.WHITE); Resources.shapeRenderer.begin(ShapeType.Line); for(int i = 0; i < buttons.size(); i++) { FFButton b = buttons.get(i); if(b.isHidden() != true) { b.drawBounds(Resources.shapeRenderer); } } Resources.shapeRenderer.end(); Resources.shapeRenderer.setColor(Color.RED); Resources.shapeRenderer.begin(ShapeType.Line); for(int i = 0; i < buttons.size(); i++) { FFButton b = buttons.get(i); if(b.isHidden() != true) { if(b.isActive() == true) { b.drawBounds(Resources.shapeRenderer); } } } Resources.shapeRenderer.end(); Resources.shapeRenderer.setColor(Color.MAGENTA); Resources.shapeRenderer.begin(ShapeType.Line); for(int i = 0; i < buttons.size(); i++) { FFButton b = buttons.get(i); if(b.isHidden() != true) { if(b.getSelected() == true) { b.drawBounds(Resources.shapeRenderer); } } } Resources.shapeRenderer.end(); } @Override public void show() { Gdx.input.setInputProcessor(this); } @Override public boolean touchDown(int screenX, int screenY, int pointer, int button) { float pointerX = InputTransform.getCursorToModelX(windowWidth, screenX); float pointerY = InputTransform.getCursorToModelY(windowHeight, screenY); for(int i = 0; i < buttons.size(); i++) { if(buttons.get(i).contains(pointerX, pointerY)) { if(buttons.get(i).isHidden() != true) { buttons.get(i).setSelected(true); } } } return true; } @Override public boolean touchUp(int screenX, int screenY, int pointer, int button) { float pointerX = InputTransform.getCursorToModelX(windowWidth, screenX); float pointerY = InputTransform.getCursorToModelY(windowHeight, screenY); for(int i = 0; i < buttons.size(); i++) { if(buttons.get(i).contains(pointerX, pointerY) && buttons.get(i).getSelected()) { buttons.get(i).execute(); } buttons.get(i).setSelected(false); } return true; } ...您可以像这样扩展：
public class ServerClientPickScreen extends AbstractMenuScreen implements FFListener{ private FFButton backButton; private FFButton clientButton; private FFButton serverButton; public ServerClientPickScreen() { super(new ArrayList<FFButton>()); backButton = new FFListenerButton(new Rectangle(400, 20, 60, 30), "Back", this); clientButton = new FFListenerButton(new Rectangle(260, 140, 80, 30), "Client", this); serverButton = new FFListenerButton(new Rectangle(140, 140, 80, 30), "Server", this); buttons.add(backButton); buttons.add(clientButton); buttons.add(serverButton); ....
