PageLayoutDemojava 2 | 一款简单的page切换 空布局、错误布局、加载布局，支持一键配置、定义，不需要xml编写 3 | 4 | > **该功能是支持单独为某个布局设置状态改变的，比如很多同学提到的我一个listview的数据没有获取到，fun initPage(targetView: Any),这个targetView你只需要设置成你的listview或者包裹你listview的parent布局就OK了，具体原理可以看下面的代码解析啊，遍历获取索引，然后记录索引值....** 5 | 6 | **如果您想看Kotlin版本，点击[https://github.com/Hankkin/PageLayoutDemo](https://github.com/Hankkin/PageLayoutDemo)** 7 | 8 | > 项目中我们经常会用到的加载数据，加载完数据后显示内容，如果没有数据显示一个空白页，这是如果网络错误了显示一个网络错误页，自定义一个PageLayout。 9 | 10 | ## 绪论 11 | Android中经常使用一个空白页和网络错误页用来提高用户体验，给用户一个较好的感官，如果获取到的数据为空，那么会显示一个空白数据页，如果在获取数据的过程中网络错误了，会显示一个网络异常页，像最近比较火的某东这样,见下图。网上也有一些开源的组件，大部分都是自定义继承某个布局在xml中让其作为跟布局，然后将自己的内容布局添加进去，效果也都不错，但是个人总觉得稍微有些麻烦，不是那么灵活，n多个xml布局都去定义，写的心烦，所以有了今天的主角。 12 | 13 | 14 | 15 | 16 | ## 思考 17 | 实现的思路实际上是和上面说的一样，只不过换了一种方式，我们手动获取到contentView，将它从DecorView中移除，然后交给PageLayout取管理。当时考虑的时候就是不想在每个xml中去写页面切换的布局，那么我们可不可以用Java代码去控制？带着下面几个问题一起来看一下。 18 | 19 | - 1.自定义一个布局让其作为跟布局 20 | - 2.提供切换**加载loading**、**空白页empty**、**错误页errror**、**内容页content**功能 21 | - 3.怎么让其取管理上边的四个页面？ 22 | - 4.contentView怎么添加？ 23 | - 5.如果我想切换的跟布局不是个Activity或者Fragment怎么办？ 24 | - 6.因为切换页面状态的功能一般都是一个APP统一的，那么可不可以一键配置呢？ 25 | 26 | ## 实现 27 | 28 | ### 1.代码设计 29 | 30 | 首先我们定义PageLayout继承FrameLayout或者LinearLayou或者其他的布局都可以，然后我们需要提供切换四个布局的功能，当然如果支持自定义就更好了，还有状态布局里面的一些属性，还方便一键配置，所以最后采用了Builder模式来创建，使用方式就和Android里面的**AlertDialog**一样，通过Builder去构建一个PageLayout。最后的样子是长这样的： 31 | 32 | | 方法 | 注释 | 33 | | :------------------------- | ----------------------------- | 34 | | showLoading() | 显示loading | 35 | | showError() | 显示错误布局 | 36 | | showEmpty() | 显示空布局 | 37 | | hide() | 显示内容布局 | 38 | | **Builder** | | 39 | | setLoading() | setLoadingText() | 40 | | setError() | setDefaultLoadingBlinkText() | 41 | | setEmpty() | setLoadingTextColor() | 42 | | setDefaultEmptyText() | setDefaultLoadingBlinkColor() | 43 | | setDefaultEmptyTextColor() | setDefaultErrorText() | 44 | | setDefaultErrorTextColor() | setEmptyDrawable() | 45 | | setErrorDrawable() | | 46 | 47 | 48 | 49 | **默认样式** 50 | ``` 51 | PageLayout.Builder(this) 52 | .initPage(ll_default) 53 | .setOnRetryListener(object : PageLayout.OnRetryClickListener{ 54 | override fun onRetry() { 55 | loadData() 56 | } 57 | 58 | }) 59 | .create() 60 | ``` 61 | 62 | **自定义样式** 63 | 64 | ``` 65 | PageLayout.Builder(this) 66 | .initPage(ll_demo) 67 | .setLoading(R.layout.layout_loading_demo) 68 | .setEmpty(R.layout.layout_empty_demo,R.id.tv_page_empty_demo) 69 | .setError(R.layout.layout_error_demo,R.id.tv_page_error_demo,object : PageLayout.OnRetryClickListener{ 70 | override fun onRetry() { 71 | loadData() 72 | } 73 | }) 74 | .setEmptyDrawable(R.drawable.pic_empty) 75 | .setErrorDrawable(R.drawable.pic_error) 76 | .create() 77 | ``` 78 | 79 | ### 2.设置PageLayout 80 | 81 | > 考虑好了代码设计方式之后，我们来具体实现功能，首先需要考虑上面的5，6点： 82 | 83 | **contentView怎么添加？** 84 | 85 | **如果我想切换的跟布局不是个Activity或者Fragment怎么办？** 86 | 87 | #### 1.Activity 88 | 如果我们要切换的跟布局是个Activity时，首先我们需要了解一下Android中的setContentView()方法，很熟悉，是我们新建完Activity后默认会在生命周期方法onCreate()中默认存在的，那么setContentView()做了些什么呢？我们先看一张图： 89 | 90 | ![image](http://lc-47sd2ifv.cn-n1.lcfile.com/f07096d512318918580c.png) 91 | 92 | > 一个Activity是通过ActivityThread创建出来的，创建完毕后，会将DecorView添加到Window中，同时会创建ViewRootImpl对象，并将ViewRootImpl对象和DecorView建立关联，setContentView()是通过getWindow()调用的，这里的window实际初始化的时候初始化为PhoneWindow，也就是说Activity会调用PhoneWindow的setContentView()将layout布局添加到DecorView上，而此时的DecorView就是那个最底层的View。然后通过LayoutInflater.infalte()方法加载布局生成View对象并通过addView()方法添加到Window上，（一层一层的叠加到Window上）所以，Activity其实不是显示视图，Window才是真正的显示视图。 93 | 94 | 再来看上面的那张图，可以说DecorView是一个界面的真正跟布局，TitleView我们可以通过设置theme样式显示隐藏的，状态布局切换时我们不考虑TitleView，我们只需要考虑ContentView，而ContentView也就是**android.R.id.content**,知道了这些我们来看看怎么获取将contenView交给PageLayout管理。 95 | 96 | #### 2.Fragment、View 97 | 98 | 如果我们要切换的跟布局是个Fragment、View时，我们只需要获取到它的parent 99 | 100 | ### 3.PageLayout设置跟布局 101 | 获取到了contentView跟布局后，我们要移除自己的显示内容的布局，并把这个布局交给PageLayout，下面看一下代码，注释的很详细了 102 | 103 | ``` 104 | /** 105 | * set target view for root 106 | */ 107 | fun initPage(targetView: Any): Builder { 108 | var content: ViewGroup? = null 109 | when (targetView) { 110 | is Activity -> { //如果是Activity，获取到android.R.content 111 | mContext = targetView 112 | content = (mContext as Activity).findViewById(android.R.id.content) 113 | } 114 | is Fragment -> { //如果是Fragment获取到parent 115 | mContext = targetView.activity!! 116 | content = (targetView.view)?.parent as ViewGroup 117 | } 118 | is View -> { //如果是View，也取到parent 119 | mContext = targetView.context 120 | try { 121 | content = (targetView.parent) as ViewGroup 122 | } catch (e: TypeCastException) { 123 | } 124 | } 125 | } 126 | val childCount = content?.childCount 127 | var index = 0 128 | val oldContent: View 129 | if (targetView is View) { //如果是某个线性布局或者相对布局时，遍历它的孩子，找到对应的索引，记录下来 130 | oldContent = targetView 131 | childCount?.let { 132 | for (i in 0 until childCount) { 133 | if (content!!.getChildAt(i) === oldContent) { 134 | index = i 135 | break 136 | } 137 | } 138 | } 139 | 140 | } else { //如果是Activity或者Fragment时，取到索引为第一个的View 141 | oldContent = content!!.getChildAt(0) 142 | } 143 | mPageLayout.mContent = oldContent //给PageLayout设置contentView 144 | mPageLayout.removeAllViews() 145 | content?.removeView(oldContent) //将本身content移除，并且把PageLayout添加到DecorView中去 146 | val lp = oldContent.layoutParams 147 | content?.addView(mPageLayout, index, lp) 148 | mPageLayout.addView(oldContent) 149 | initDefault() //设置默认状态布局 150 | return this 151 | } 152 | ``` 153 | 154 | 这样我们就解决了上面的5，6的问题。 155 | 156 | ### 4.其他 157 | 158 | - **因为错误布局中一般都包括一个点击重试的功能，如果你需要自定义布局，你可以在配置PageLayout之前，设置好错误布局和点击事件，然后setError进去，同时也提供了一个默认方式的方法** 159 | 160 | ``` 161 | fun setError(errorView: Int, errorClickId: Int, onRetryClickListener: OnRetryClickListener) 162 | ``` 163 | - **考虑到此功能的APP统一性，所以并没有提供过多的自定义功能，如果你需要的话，你都可以提前设置好View，然后进行set** 164 | - **之前和同事讨论，xml形式和代码形式哪个更方便更灵活，这些都属于个人喜好吧，如果你更喜欢在xml里写的话，你可以进行改造，也挺简单，目前没提供xml方式，PageLayout的初衷就是模仿AlertDialog方式，随时随地使用状态布局切换** 165 | - **你也可以在BaseActivity和BaseFragment中进行PageLayout的初始化，Demo中未使用，自行解决** 166 | 167 | ## 效果图 168 | 169 | ![image](http://lc-47sd2ifv.cn-n1.lcfile.com/a2a787511ddb0461bfb1.gif) 170 | 171 | 172 |
