如何设置版式的宽度和高度的动画？

当然可以。

只需编写自己的自定义动画并修改

LayoutParams

它看起来像这样：

public class ResizeAnimation extends Animation {    private int startHeight;    private int deltaHeight; // distance between start and end height    private View view;        public ResizeAnimation (View v) {        this.view = v;    }    @Override    protected void applyTransformation(float interpolatedTime, Transformation t) {        view.getLayoutParams().height = (int) (startHeight + deltaHeight * interpolatedTime);        view.requestLayout();    }        public void setParams(int start, int end) {        this.startHeight = start;        deltaHeight = end - startHeight;    }        @Override    public void setDuration(long durationMillis) {        super.setDuration(durationMillis);    }    @Override    public boolean willChangeBounds() {        return true;    }}

在代码中， 创建一个新的Animation并将其应用于 要设置动画 的RelativeLayout ：

RelativeLayout relativeLayout = (RelativeLayout) ((LinearLayout) view.findViewById(viewId)).getParent();// getting the layoutparams might differ in your application, it depends on the parent layoutRelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) relativeLayout.getLayoutParams();ResizeAnimation a = new ResizeAnimation(relativeLayout);a.setDuration(500);// set the starting height (the current height) and the new height that the view should have after the animationa.setParams(lp.height, newHeight);relativeLayout.startAnimation(a);
