  • Android 控件的显示隐藏上下左右移动动画

    一、利用Android提供的左右移动工具类:AnimationUtils

        LinearLayout ll_first = (LinearLayout) findViewById(R.id.ll_first);
        LinearLayout ll_second = (LinearLayout) findViewById(R.id.ll_second);
        ll_first.setVisibility(View.GONE);
        ll_second.setVisibility(View.VISIBLE);
        // 向右边移出
        ll_first.setAnimation(AnimationUtils.makeOutAnimation(this, true));
        // 向右边移入
        ll_second.setAnimation(AnimationUtils.makeInAnimation(this, true));
    
        
        
        
        ll_first.setVisibility(View.VISIBLE);
        ll_second.setVisibility(View.GONE);
        // 向左边移入
        ll_first.setAnimation(AnimationUtils.makeInAnimation(this, false));
        // 向左边移出
        ll_second.setAnimation(AnimationUtils.makeOutAnimation(this, false));

    二、用TranslateAnimation添加动画

    先写一个AnimationUtil工具类:这里仅提供上下移动效果

    public class AnimationUtil {
        private static final String TAG = AnimationUtil.class.getSimpleName();
    
        /**
         * 从控件所在位置移动到控件的底部
         *
         * @return
         */
        public static TranslateAnimation moveToViewBottom() {
            TranslateAnimation mHiddenAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
                    Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
                    0.0f, Animation.RELATIVE_TO_SELF, 1.0f);
            mHiddenAction.setDuration(500);
            return mHiddenAction;
        }
    
        /**
         * 从控件的底部移动到控件所在位置
         *
         * @return
         */
        public static TranslateAnimation moveToViewLocation() {
            TranslateAnimation mHiddenAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0.0f,
                    Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
                    1.0f, Animation.RELATIVE_TO_SELF, 0.0f);
            mHiddenAction.setDuration(500);
            return mHiddenAction;
        }
    }
    

    隐藏的时候设置下动画就可以了

                    ll_first.setVisibility(View.GONE);
                    ll_second.setVisibility(View.VISIBLE);
                    ll_first.setAnimation(AnimationUtil.moveToViewBottom());
                    ll_second.setAnimation(AnimationUtil.moveToViewLocation());
