如何使 android 对象动画师响应？

Question

此处的值 200 在不同的屏幕上会产生不同的结果。有什么办法可以解决这个问题吗？

 MarginProxy marginProxy = new MarginProxy(fab);
                        ObjectAnimator marginAnimation = ObjectAnimator.ofInt(marginProxy, "bottomMargin", 530, 200).setDuration(300);
                        marginAnimation.start();

当动画开启时运行，按钮在另一个屏幕（像素）上和另一个设备（三星 J7）上的另一个位置移动不同
这是保证金代理 class

class MarginProxy {
    private View mView;

    public MarginProxy(View view) {
        mView = view;
    }
public int getLeftMargin() {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    return lp.leftMargin;
}

public void setLeftMargin(int margin) {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    lp.setMargins(margin, lp.topMargin, lp.rightMargin, lp.bottomMargin);
    mView.requestLayout();
}

public int getTopMargin() {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    return lp.topMargin;
}

public void setTopMargin(int margin) {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    lp.setMargins(lp.leftMargin, margin, lp.rightMargin, lp.bottomMargin);
    mView.requestLayout();
}

public int getRightMargin() {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    return lp.rightMargin;
}

public void setRightMargin(int margin) {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    lp.setMargins(lp.leftMargin, lp.topMargin, margin, lp.bottomMargin);
    mView.requestLayout();
}

public int getBottomMargin() {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    return lp.bottomMargin;
}

public void setBottomMargin(int margin) {
    MarginLayoutParams lp = (MarginLayoutParams) mView.getLayoutParams();
    lp.setMargins(lp.leftMargin, lp.topMargin, lp.rightMargin, margin);
    mView.requestLayout();
}
}

Answer 1

您必须使用 Dips 而不是使用像素。

public int convertDiptoPix(int dip){
float scale = getDensity();
return (int) (dip * scale + 0.5f);}

然后将您的“200”像素值交换为该方法的结果。
