Question

我想动画几行轨道上的按钮...... 例如，我想要将按钮从点A（0,0）设置为点B（100,100），然后从B设置为C（200,0）。问题在于我这样做的方式，在A - > B和B - > C动画之间，我的视图表现得非常奇怪，它无缘无故地在B位置周围振动。为什么会这样？

另一个问题是，当我为A到B的按钮设置动画时，此路线中的速度会发生变化。我怎么解决这个问题？

这是我的代码：

import android.view.animation.Animation;
import android.view.animation.AnticipateOvershootInterpolator;
import android.view.animation.TranslateAnimation;


public class LinearAnimation {
    public Animation fromAtoB(float fromX, float fromY, float toX, float toY, Animation.AnimationListener l, int speed){


        Animation fromAtoB = new TranslateAnimation(
                Animation.ABSOLUTE, //from xType
                fromX,
                Animation.ABSOLUTE, //to xType
                toX,
                Animation.ABSOLUTE, //from yType
                fromY,
                Animation.ABSOLUTE, //to yType
                toY
        );

        fromAtoB.setDuration(speed);
        fromAtoB.setInterpolator(new AnticipateOvershootInterpolator(1.0f));


        if(l != null)
            fromAtoB.setAnimationListener(l);
        return fromAtoB;
    }
}

和

  Animation.AnimationListener animL = new Animation.AnimationListener() {

            @Override
            public void onAnimationStart(Animation animation) {
            }

            @Override
            public void onAnimationEnd(Animation animation) {
                btn.clearAnimation();
                /*rl=new RelativeLayout.LayoutParams(40,40);
                rl.leftMargin=DataBase.endX-(int)(btn.getWidth()/2);
                rl.topMargin=DataBase.endY-(int)(btn.getHeight()/2);
                btn.setLayoutParams(rl);*/
                if (DataBase.endX>=DataBase.Layout_Width+40)
                {
                    System.out.println("FINISHED");
                    btn.setVisibility(View.GONE);
                    stopLooping=true;
                }
                else
                {

                    setCoordinates();
                }
            }

            @Override
            public void onAnimationRepeat(Animation animation) {
            }
        };
        LinearAnimation anim = new LinearAnimation();
        System.out.println(DataBase.startX+"  "+ DataBase.startY+"  "+DataBase.endX+"  "+DataBase.endY+"  "+negative);
        Animation a = anim.fromAtoB(DataBase.startX, DataBase.startY, DataBase.endX, DataBase.endY, animL,5000);
        a.setFillAfter(false);
        btn.setAnimation(a);
    }

不要在动画上使用AnticipateOvershootInterpolator 请改用AccelerateDecelerateInterpolator。

特定协调之间的动画按钮视图
