我在我的应用程序中创建了一个显示文本字段和按钮的屏幕，但由于某种原因我无法单击它们。你知道可能是什么原因。这是我的代码（我跳过了变量声明）：

public class SentenceScreen implements Screen {
public SentenceScreen(Game g) {
    game = g;
}

@Override
public void render(float delta) {
    // TODO Auto-generated method stub
    Gdx.gl.glClearColor(0,0,0,0);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    stage = new Stage();

    Skin skin = new Skin(Gdx.files.internal("uiskin.json"));

    btnLogin = new TextButton("Click me", skin);
    btnLogin.setPosition(300, 50);
    btnLogin.setSize(100, 60);
    stage.addActor(btnLogin);

    textField = new TextField("", skin);
    textField.setPosition(100, 50);
    textField.setSize(190, 60);
    stage.addActor(textField);

    stage.act(delta);
    stage.draw();

    Gdx.input.setInputProcessor(stage);
}
   }

stage = new Stage();

Skin skin = new Skin(Gdx.files.internal("uiskin.json"));

btnLogin = new TextButton("Click me", skin);
btnLogin.setPosition(300, 50);
btnLogin.setSize(100, 60);
stage.addActor(btnLogin);

textField = new TextField("", skin);
textField.setPosition(100, 50);
textField.setSize(190, 60);
stage.addActor(textField);

Gdx.input.setInputProcessor(stage);

所有这些都不应该在您的 render() 方法中。相反，将实例化放在 show() 方法或您的构造函数中。它还将大大减少延迟。

为什么您的按钮不起作用：您每帧实例化一个新阶段，并将 InputProcessor 分配给它。您的实际代码中没有时间来处理实际输入。

这是您的课程的外观：

public class SentenceScreen implements Screen {
public SentenceScreen(Game g) {
    game = g;
}

@Override
public void render(float delta) {
// TODO Auto-generated method stub
Gdx.gl.glClearColor(0,0,0,0);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

stage.act(delta);
stage.draw();
}

@Override
public void show() {

stage = new Stage();

Skin skin = new Skin(Gdx.files.internal("uiskin.json"));

btnLogin = new TextButton("Click me", skin);
btnLogin.setPosition(300, 50);
btnLogin.setSize(100, 60);
stage.addActor(btnLogin);

textField = new TextField("", skin);
textField.setPosition(100, 50);
textField.setSize(190, 60);
stage.addActor(textField);

Gdx.input.setInputProcessor(stage);
}
}
