android中如何实现滑动activity？如何左右滑动实现activity的切换？

你是要滑动切换activity还是页面？如果是activity的话你可以给当前页面添加手势，滑动的时候实现activity的切换然后给activity添加切换动画，如果是像qq那种效果可以用tab来做，实现效果很不错，或者activitygroup，还可以用fragment来做，这些实现效果都不错。如果是页面滑动切换，可以用viewpager，这个效果很好，代码能力强就用viewgroup的滚动来实现，效果也还可以。

Android左右滑屏切换怎么做？像uc浏览器首页那样的，左右滑动时按钮上的蓝色条也跟着动，该怎么做

滑屏 部分可以用Viewpager来实现,至于上面按钮的蓝色条,是可以通过ViewPager的pageChangeListener,监听滑动的换页进行改变

android中怎么实现类似驾校一点通的滑动切换到下一题的效果

可以使用android 提供的viewpager控件，就可以实现滑动切换下一个界面，也可以监听手势的滑动动作

网页名称：android滑动切换,android实现界面滑动
