9 | ![image](https://github.com/yipianfengye/android-xmviewpager/blob/master/images/20160922095746542.gif) 10 | 11 | 12 | **实现说明** 13 | 14 | 本项目是通过TabLayout+ViewPager的方式实现的，这里我们首先看一下整个页面的布局文件的实现方式： 15 | 16 | ``` 17 | 18 | 25 | 30 | 36 | 37 | 46 | 47 | 48 | 49 | 54 | 55 | 56 | ``` 57 | 58 | 可以发现其是通过TabLayout和ViewPager的方式实现的，在实现过程中由于要求点击跨多个Tab的时候屏蔽多次滑动效果，这里重写了TabLayout的onTabSelectedListener监听： 59 | 60 | ``` 61 | /** 62 | * 自定义函数, : Unit 表示函数没有返回值 63 | */ 64 | fun initViewPager() : Unit { 65 | /** 66 | * 获取初始化数据 67 | */ 68 | val titles = ViewData().getTitles() 69 | 70 | /** 71 | * as 类似于java中的类型强转 72 | */ 73 | val toolbar = findViewById(R.id.toolbar) as Toolbar 74 | setSupportActionBar(toolbar) 75 | mViewPager = findViewById(R.id.viewpager) as ViewPager 76 | mTabLayout = findViewById(R.id.tabs) as TabLayout 77 | 78 | /** 79 | * 通过 in 关键字实现循环遍历 80 | * 在调用mTabLayou变量的方法时,由于mTabLayout可能为空,所以在调用方法时添加!! 81 | * titles[] 与 titles.get 方法的功能是一样的 82 | * titles.indices 获取的是数组的下标 83 | */ 84 | for (i in titles.indices) { 85 | mTabLayout!!.addTab(mTabLayout!!.newTab().setText(titles[i])) 86 | } 87 | 88 | val fragments = ArrayList() 89 | 90 | /** 91 | * 循环遍历添加ViewPager的Fragment 92 | */ 93 | for (i in titles.indices) { 94 | val listFragment = MListFragment() 95 | val bundle = Bundle() 96 | val sb = StringBuffer() 97 | for (j in 1..8) { 98 | sb.append(titles[i]).append(" ") 99 | } 100 | bundle.putString("content", sb.toString()) 101 | listFragment.arguments = bundle 102 | fragments.add(listFragment) 103 | } 104 | 105 | val mFragmentAdapteradapter = MFragmentAdapter(supportFragmentManager, fragments, titles) 106 | mViewPager!!.adapter = mFragmentAdapteradapter 107 | mViewPager!!.adapter = mFragmentAdapteradapter 108 | mTabLayout!!.setupWithViewPager(mViewPager) 109 | mTabLayout!!.setTabsFromPagerAdapter(mFragmentAdapteradapter) 110 | 111 | /** 112 | * 自定义设置ViewPager切换动画 113 | */ 114 | mViewPager!!.setPageTransformer(true, MTransformer()) 115 | 116 | /** 117 | * 通过object : TabLayout.OnTabSelectedListener 的方式创建内部匿名类(这里主要是接口) 118 | */ 119 | mTabLayout!!.setOnTabSelectedListener(object : TabLayout.OnTabSelectedListener { 120 | override fun onTabReselected(tab: TabLayout.Tab?) { 121 | } 122 | 123 | override fun onTabUnselected(tab: TabLayout.Tab?) { 124 | } 125 | 126 | override fun onTabSelected(tab: TabLayout.Tab?) { 127 | /** 128 | * 控制变量 129 | */ 130 | if (isOk) { 131 | isOk = false 132 | val currentItemIndex = mViewPager!!.currentItem 133 | 134 | if (Math.abs(currentItemIndex - tab!!.position) > 1) { 135 | /** 136 | * 向后点击 137 | */ 138 | if (currentItemIndex <= tab!!.position) { 139 | mViewPager!!.setCurrentItem(tab.position - 1, false) 140 | mViewPager!!.setCurrentItem(tab.position, true) 141 | } 142 | /** 143 | * 向前点击 144 | */ 145 | else { 146 | mViewPager!!.setCurrentItem(tab.position + 1, false) 147 | mViewPager!!.setCurrentItem(tab.position, true) 148 | } 149 | } else { 150 | mViewPager!!.setCurrentItem(tab.position, true) 151 | } 152 | 153 | isOk = true 154 | } 155 | } 156 | }) 157 | 158 | } 159 | ``` 160 | 161 | 然后我们可以看一下数据初始化是如何实现的： 162 | 163 | ``` 164 | /** 165 | * Created by aaron on 16/9/14. 166 | * 主要用于保存界面ViewPager数据 167 | */ 168 | class ViewData { 169 | 170 | /** 171 | * 该方法用于获取ViewPager TAB 显示数据 172 | */ 173 | fun getTitles() : ArrayList { 174 | /** 175 | * 通过类名创建该类的对象,这里直接调用java中的集合框架 176 | */ 177 | val titles = ArrayList() 178 | 179 | titles.clear() 180 | titles.add("推荐") 181 | titles.add("视频") 182 | titles.add("热点") 183 | titles.add("娱乐") 184 | titles.add("体育") 185 | titles.add("北京") 186 | titles.add("财经") 187 | titles.add("科技") 188 | titles.add("汽车") 189 | titles.add("社会") 190 | titles.add("搞笑") 191 | titles.add("军事") 192 | titles.add("历史") 193 | titles.add("涨知识") 194 | titles.add("NBA") 195 | titles.add("两性") 196 | 197 | return titles 198 | } 199 | 200 | } 201 | ``` 202 | 203 | 204 | 这其中需要注意的是：viewPager的setCurrentItem方法，表示会将viewPager的当前显示Item设置为指定的item，而我们可以发现这里的setCurrentItem有两个参数，第一个参数，是显示当前Item的position，而第二个参数为boolean类型，表示是否有滑动效果，比如当前我们在ViewPager的第一项，而我们点击了TabLayout的第八项，这时候如果我们调用了：setCurrentItem(8, true),它表示我们将滑动到ViewPager的第八项，且有滚动效果。这样我们做一下变通，当我们点击的TabLayout与当前Item的距离大于一个Item的时候就先滑动到当前Item的前一个并且没有滑动效果，然后在执行一次setCurrentItem方法，这样在跨多个Tab点击的时候就屏蔽了多个Item滚动的效果了。 205 | 206 | 207 | 在实现过程中还需要实现滑动覆盖的效果，一开始想了很久包括使用ViewPager的setPageTransformer方法，但是还是没法实现这个思路，后来经过同事指点，终于搞定了。就是对ViewPager每一项item中的子View执行动画效果，这样就会实现需求的动画效果了。 208 | 209 | 以下是自己重写的setPageTransformer类： 210 | 211 | ``` 212 | /** 213 | * Created by aaron on 16/9/13. 214 | * 自定义实现ViewPager的切换动画效果 215 | */ 216 | class MTransformer : ViewPager.PageTransformer { 217 | 218 | /** 219 | * 回调方法,重写viewpager的切换动画 220 | */ 221 | override fun transformPage(view: View, position: Float) { 222 | val pageWidth = view.width 223 | val wallpaper = view.findViewById(R.id.recycler_view) 224 | if (position < -1) { // [-Infinity,-1) 225 | wallpaper.translationX = 0.toFloat() 226 | view.translationX = 0.toFloat() 227 | } else if (position <= 1) { // [-1,1] 228 | wallpaper.translationX = pageWidth * getFactor(position) 229 | view.translationX = 8 * position 230 | } else { // (1,+Infinity] 231 | wallpaper.translationX = 0.toFloat() 232 | view.translationX = 0.toFloat() 233 | } 234 | } 235 | 236 | private fun getFactor(position: Float): Float { 237 | return -position / 2 238 | } 239 | 240 | } 241 | ``` 242 | 可以看到在我们自定义的PageTransformer中，我们通过findViewById方法获取了滑动Item的子View，并对子View执行translationX操作，进而实现了滑动Item的遮盖效果。 243 | 244 | 另外由于本文主要介绍Kotlin的使用，更多关于Kotlin的相关知识点，可参考： 245 | 246 | Basic Syntax - Kotlin Programing 247 | 248 | Kotlin：Android事件的Swift 249 | 250 | Kotlin在Android工程中的应用 251 | 252 | 当然更具体的关于本控件的实现可以下载源码参考。 253 | 254 | **总结：** 255 | 256 | 以上就是通过Kotlin实现的仿照UC头条ViewPager左右滑动效果的小项目。当然现在还很不完善，对于源码有兴趣的同学可以到github上看一下具体实现。项目地址：android-xmviewpager 257 | 258 | 259 |
