开启 摇一摇动画 * * @param isBack 是否是返回初识状态

private void startAnimation(boolean isBack) {
    //动画坐标移动的位置的类型是相对自己的
    int type = Animation.RELATIVE_TO_SELF;

    float topFromY;
    float topToY;
    float bottomFromY;
    float bottomToY;
    if (isBack) {
        topFromY = -0.5f;
        topToY = 0;
        bottomFromY = 0.5f;
        bottomToY = 0;
    } else {
        topFromY = 0;
        topToY = -0.5f;
        bottomFromY = 0;
        bottomToY = 0.5f;
    }

上面图片的动画效果

    TranslateAnimation topAnim = new TranslateAnimation(
            type, 0, type, 0, type, topFromY, type, topToY
    );
    topAnim.setDuration(200);
    动画终止时停留在最后一帧~不然会回到没有执行之前的状态
    topAnim.setFillAfter(true);

   底部的动画效果
    TranslateAnimation bottomAnim = new TranslateAnimation(
            type, 0, type, 0, type, bottomFromY, type, bottomToY
    );
    bottomAnim.setDuration(200);
    bottomAnim.setFillAfter(true);

    大家一定不要忘记, 当要回来时, 我们中间的两根线需要GONE掉
    if (isBack) {
        bottomAnim.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {}
            @Override
            public void onAnimationRepeat(Animation animation) {}
            @Override
            public void onAnimationEnd(Animation animation) {
                //当动画结束后 , 将中间两条线GONE掉, 不让其占位
                mTopLine.setVisibility(View.GONE);
                mBottomLine.setVisibility(View.GONE);
            }
        });
    }
   设置动画
    mTopLayout.startAnimation(topAnim);
    mBottomLayout.startAnimation(bottomAnim);

}

}
