Question

我正在使用动画在屏幕上移动一个对象，但动画似乎同时运行。例如，当我选择向上和向下时，对象保持不变。随着2个向上和向下移动，对象向上移动1.我希望它向上移动1，然后再向下移动1和向上移动1。有什么办法吗？这是我的代码：

                int totalx = 0;
                int totaly = 0;

                for (int j=0; j<moves.size(); j++){

                if (moves.get(j).equals("up")) {
                    Animation animation = new TranslateAnimation(0, 0 , 0, -(63+totaly));
                    animation.setDuration(1000);
                    animation.setFillAfter(true);
                    circle.startAnimation(animation);
                    totaly = totaly - 63;


                }
                else if (moves.get(j).equals("down")) {
                    Animation animation = new TranslateAnimation(0, 0 , 0, (63+totaly));
                    animation.setDuration(1000);
                    animation.setFillAfter(true);
                    circle.startAnimation(animation);
                    totaly = totaly + 63;

                }
                else if (moves.get(j).equals("left")) {
                    Animation animation = new TranslateAnimation(0, -63 , 0, -(63+totaly));
                    animation.setDuration(1000);
                    animation.setFillAfter(true);
                    circle.startAnimation(animation);
                    totalx = totalx + 63;

                }
                else if (moves.get(j).equals("right")) {
                    Animation animation = new TranslateAnimation(0, 63 , 0, (63+totaly));
                    animation.setDuration(1000);
                    animation.setFillAfter(true);
                    circle.startAnimation(animation);
                    totalx = totalx + 63;

                }
                    }

您必须使用AnimationSet来链接个人Animations。

AnimatorSet s = new AnimatorSet();
s.play(anim2).after(anim1);
