Question

我一直试着让我的应用程序转移到下一个类“GameOver.class”。有人能指出我做错了什么吗？根据我的日志，OnAnimationEnd方法甚至没有被击中。如果我将它用作主类，GameOver类就可以工作。

public class Rocky extends Activity implements AnimationListener {

TextView m_dog, m_spoon, m_ice_cream, m_car, m_giraffe ;
ImageView rocky_pic, dog, spoon,ice_cream, car, giraffe;
Animation animationFadeOut, animationFadeIn,viewObjFades;
int count = 0;
MediaPlayer mp;
private static final String TAG = "MyActivity";
AlertDialog.Builder builder;
AlertDialog alertDialog;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.rocky);

    rocky_pic = (ImageView)findViewById(R.id.rocky_pic);


    Animation animationFadeIn = AnimationUtils.loadAnimation(this, R.anim.fadein);
    rocky_pic.startAnimation(animationFadeIn);

    m_car=(TextView) findViewById(R.id.m_car);
    m_dog=(TextView) findViewById(R.id.m_dog);
    m_spoon=(TextView) findViewById(R.id.m_spoon);
    m_ice_cream=(TextView) findViewById(R.id.m_ice_cream);
    m_giraffe=(TextView) findViewById(R.id.m_giraffe);

    dog = (ImageView) findViewById(R.id.dog);
    spoon = (ImageView) findViewById(R.id.spoon);
    ice_cream = (ImageView) findViewById(R.id.ice_cream);
    car = (ImageView) findViewById(R.id.car);
    giraffe  = (ImageView) findViewById(R.id.giraffe);

    mp = MediaPlayer.create(Rocky.this, R.raw.ding); 
    dog.setAlpha(0);
    spoon.setAlpha(0);
    ice_cream.setAlpha(0);
    car.setAlpha(0);
    giraffe.setAlpha(0);

}

Answer 1

我写了一个方法调用，“next（）”并取出“fadeout（）”。它现在有效，但我不明白为什么。有人可以解释一下吗？

public void next(){
    mp.release();
    Intent done = new Intent(this, GameOver.class);
    done.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    done.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
    this.startActivity(done);
}

Answer 2

您在启动动画时立即将rocky_pic的可见性设置为Gone。因为它是一个淡出动画，你不应该简单地将动画设置为fill_after，以便在动画结束时它保持不变吗？我认为设置它已经消失，可能会完全停止动画，因此动画被有效取消，这就是为什么onAnimationEnd永远不会被调用bc你通过改变它的可见性有效地使视图无效。

为什么我的应用程序不会移动到下一个类（意图）？
