图像移动动画不起作用

Question

目前我正在进行像shell游戏一样的简单游戏。它在Lollipop，Marshmallow，Nougat和KitKat 4.4.2中运行良好，但在其他KitKat版本设备和Jellybean中不起作用。

移动动画代码

public class BottomLeftToRightAnimation extends Animation {
private View view;
private float prevX,prevY;
private float cx,cy;
private float prevDx,prevDy;
private float r;
public BottomLeftToRightAnimation(View view,float r){
    this.view = view;
    this.r = r;
}

@Override
public boolean willChangeBounds() {
    return true; // animation will change the view bounds
}

@Override
public void initialize(int width, int height, int parentWidth, int parentHeight) {
    // center position of image
    int cxImage = width/2;
    int cyImage = height/2;
    cx = view.getLeft() + cxImage;
    cy = view.getTop() + cyImage;

    //starting point of image rotation
    prevX = cx+r;
    prevY = cy;
}

// helps to get transformation between the interpolatedTime 0 to 1
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
    if (interpolatedTime == 0){
        t.getMatrix().setTranslate(prevDx,prevDy);
        return;
    }
    float angD = (interpolatedTime * -180f) % 180;
    float angR = (float) Math.toRadians(angD);

    float x = (float) (cx + r * Math.cos(angR));
    float y = (float) (cy + r * Math.sin(angR)/1.5);

    float dx = prevX - x;
    float dy = prevY - y;

    prevX = x;
    prevY = y;

    prevDx = dx;
    prevDy = dy;
    t.getMatrix().setTranslate(dx,dy);
}
}

同样，我为所有轮换编写了代码。我看到很多类似问题的问题。建议使用basket[1].setLayerType(View.LAYER_TYPE_HARDWARE,null);或basket[1].setLayerType(View.LAYER_TYPE_SOFTWARE,null);，但它不能解决问题。请帮我解决这个问题。

尝试将背景图层设置为一种颜色，例如#FFFFFF删除动画留下的重影。
