此处,值200在不同的屏幕上会有所不同。有什么办法可以解决这个问题?

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

运行动画时,按钮在另一个屏幕(像素)上的移动方式不同,并在另一个设备(三​​星J7)上的另一个位置移动
这是保证金代理类

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();
}
}

不必使用像素,而必须使用Dips。

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。
