Android仿腾讯WiFi底部导航

需求就是实现一个类似腾讯WiFi的底部导航

先上一个效果图

实现思路
（1）UI布局我采用的 RelativeLayout 加FrameLayout 还有RadioGroup来实现的
（2）中间那个WiFi按钮是一个属性动画效果（缩放与渐变）

XML代码

*适配我采用的是鸿洋大神的autolayout，所以布局是AutoRelativeLayout

按钮动画代码
【1】开启动画

    private void StartFlash() {
        AlphaAnimation alphaAnimation = new AlphaAnimation(0, 1.0f);
        alphaAnimation.setDuration(440);

        ScaleAnimation scaleAnimation = new ScaleAnimation(
                0, 1,
                0, 1,
                Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        scaleAnimation.setDuration(440);
        AnimationSet animationSet = new AnimationSet(false);
        animationSet.addAnimation(alphaAnimation);
        animationSet.addAnimation(scaleAnimation);
        ll_btn.startAnimation(animationSet);
        xy =true;
    }

【2】关闭动画

 private void StopFlash() {
        AlphaAnimation alphaAnimation = new AlphaAnimation(1.0f, 0);
        alphaAnimation.setDuration(440);

        ScaleAnimation scaleAnimation = new ScaleAnimation(
                1, 0,
                1, 0,
                Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
        scaleAnimation.setDuration(440);
        AnimationSet animationSet = new AnimationSet(false);
        animationSet.addAnimation(alphaAnimation);
        animationSet.addAnimation(scaleAnimation);
        ll_btn.startAnimation(animationSet);
        animationSet.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
                rbWifi.setVisibility(View.VISIBLE);
                ll_btn.setVisibility(View.GONE);
                xy =false;
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });

    }
