Question

我正在写一个游戏应用程序。如果用户按下错误按钮我想要显示动画，当动画完成时，则完成（）我的游戏;

目前，我的动画刚刚在调用完成后启动。我希望动画完成。

下面是我的实现AnimationListener

的类

public final class DisplayNextView implements Animation.AnimationListener {
    View changeView;
    Drawable image;

    public DisplayNextView(View parChangeView, Drawable parImage) {
        this.changeView = parChangeView;
        this.image = parImage;
    }

    public void onAnimationStart(Animation animation) {
        changeView.post(new SwapViews(changeView, image));
        changeView.postDelayed(new SwapViews(changeView, null), 1000);
    }

    public void onAnimationEnd(Animation animation) {

    }

    public void onAnimationRepeat(Animation animation) {

    }
}

这是我开始动画的主要活动方法

private void applyRotation(View parChangeView, Drawable image, float start, float end) {
        // Find the center of image
        final float centerX = parChangeView.getWidth() / 2.0f;
        final float centerY = parChangeView.getHeight() / 2.0f;

        // Create a new 3D rotation with the supplied parameter
        // The animation listener is used to trigger the next animation
        final Flip3DAnimation rotation =
               new Flip3DAnimation(start, end, centerX, centerY);
        rotation.setDuration(250);
        rotation.setFillAfter(true);
        rotation.setInterpolator(new AccelerateInterpolator());
        rotation.setAnimationListener(new DisplayNextView (parChangeView,image));
        parChangeView.startAnimation(rotation);
        //return rotation;
        }

这是我的SwapView类，这是一个线程

public final class SwapViews implements Runnable {
    View changeView;
    Drawable image;

    public SwapViews(View parChangeView, Drawable parImage) {
        this.changeView = parChangeView;
        this.image = parImage;
    }

    public void run() {
        final float centerX = changeView.getWidth() / 2.0f;
        final float centerY = changeView.getHeight() / 2.0f;
        Flip3DAnimation rotation;
        changeView.setBackgroundDrawable(image);
        //TODO should find a better way!!
        if (image==null)
            changeView.setBackgroundColor(Color.BLACK);


        rotation = new Flip3DAnimation(-90, 0, centerX, centerY);


        rotation.setDuration(250);
        rotation.setFillAfter(true);
        rotation.setInterpolator(new DecelerateInterpolator());

        changeView.startAnimation(rotation);

    }
}

Answer 1

你能更具体地说这个'动画'是什么吗？它是一个你自己玩框架或只是一个图像或视频的类吗？

如果这是第一个最好的方法是创建一个回调方法，并在动画完成后触发它。

Answer 2

这样的事情：

public final class DisplayNextView implements Animation.AnimationListener {
View changeView;
Drawable image;
boolean mIsCorrect;
Activity mContext;

public DisplayNextView(View parChangeView, Drawable parImage,
        boolean isCorrect, Activity context) {
    this.changeView = parChangeView;
    this.image = parImage;
    mIsCorrect = isCorrect;
    mContext = context;
}

public void onAnimationStart(Animation animation) {
    changeView.post(new SwapViews(changeView, image));
    changeView.postDelayed(new SwapViews(changeView, null), 1000);
}

public void onAnimationEnd(Animation animation) {
    if (mIsCorrect == false) {
        mContext.finish();
    }
}

public void onAnimationRepeat(Animation animation) {

}
}

无论猜测是否正确，都应该通过你的applyRotation：

private void applyRotation(View parChangeView, Drawable image, float start,
        float end, boolean isCorrect) {
    // Find the center of image
    final float centerX = parChangeView.getWidth() / 2.0f;
    final float centerY = parChangeView.getHeight() / 2.0f;

    // Create a new 3D rotation with the supplied parameter
    // The animation listener is used to trigger the next animation
    final Flip3DAnimation rotation = new Flip3DAnimation(start, end,
            centerX, centerY);
    rotation.setDuration(250);
    rotation.setFillAfter(true);
    rotation.setInterpolator(new AccelerateInterpolator());
    rotation.setAnimationListener(new DisplayNextView(parChangeView, image, isCorrect, this));
    parChangeView.startAnimation(rotation);
    // return rotation;
}

android等待动画在活动结束前完成
