AndroidAnimateGONE可见性

在我的应用程序中,我有RelativeLayout任何小部件,进入布局,我想通过xml动画向上移动.RelativeLayout可见性是GONE必须GONE再次设置可见性并将其移动到上方.

我的问题是这个,再次设置visibilty GONE移动动画不工作和改变visibilty后VISIBLE,RelativeLayout可以显示,但只有那个孩子们向上移动,我想RelativeLayout与所有chilss移动到顶部.如何解决这个问题？

XML动画:

动画代码:

animMoveUp = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.animation_move_up);
uiFiller.toolbarLinearlayoutIcons.setVisibility(View.VISIBLE);
uiFiller.toolbarLinearlayoutIcons.startAnimation(animMoveUp);

我的布局:

在这个布局中我想移动toolbarLinearlayoutIconsid

您可以使用xml中的1行将其放在父布局上

    android:animateLayoutChanges="true"

使用以下方法展开和折叠所需的视图:

public void expand(final View v) {
    v.measure(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
    final int targtetHeight = v.getMeasuredHeight();
    if (v.isShown()) {
        collapse(v);
    } else {
        v.getLayoutParams().height = 0;
        v.setVisibility(View.VISIBLE);
        Animation a = new Animation() {
            @Override
            protected void applyTransformation(float interpolatedTime,
                    Transformation t) {
                v.getLayoutParams().height = interpolatedTime == 1 ? LayoutParams.WRAP_CONTENT
                        : (int) (targtetHeight * interpolatedTime);
                v.requestLayout();
            }

            @Override
            public boolean willChangeBounds() {
                return true;
            }
        };
        a.setDuration((int) (targtetHeight + 500));
        v.startAnimation(a);
    }

}

public void collapse(final View v) {
    final int initialHeight = v.getMeasuredHeight();
    Animation a = new Animation() {
        @Override
        protected void applyTransformation(float interpolatedTime,
                Transformation t) {
            if (interpolatedTime == 1) {
                v.setVisibility(View.GONE);
            } else {
                v.getLayoutParams().height = initialHeight
                        - (int) (initialHeight * interpolatedTime);
                v.requestLayout();
            }
        }

        @Override
        public boolean willChangeBounds() {
            return true;
        }
    };

    a.setDuration((int) (v.getLayoutParams().height + 500));
    v.startAnimation(a);
}
