29 | ## 关于 Binding
30 |
31 | > 因 Jcenter 即将被废弃，已经将 Binding 迁移到 mavenCentral
32 |
33 | Binding 简化 DataBinding 和 ViewBinding 的使用， 只需要一行代码即可实现 DataBinding 和 ViewBinding。
34 |
35 | Binding 未来的规划提供通用的 `findViewById` 解决方案，，因技术的迭代更新从 butterknife 、 DataBinding 、 Kotlin 合成方法（Synthetic 视图）到现在 ViewBinding ， 未来也有可能出现新的技术，无论技术怎么变化，只需要更新 Binding ，对外的使用保持不变。
36 |
37 | * Kotlin 合成方法（Synthetic 视图）比 ViewBinding 方便这么多，为什么会被 Google 抛弃掉，请查看这篇文章 [Kotlin 插件的落幕，ViewBinding 的崛起](https://mp.weixin.qq.com/s/FxrRyXp9-VDdv-mfkzsIsA)。
38 |
39 | * 这篇文章 [竟然如此简单，DataBinding 和 ViewBinding](https://mp.weixin.qq.com/s/omn7AhHzihhtr0vtq6csNg) 从使用的角度分析了 DataBinding 和 ViewBinding 不同之处，同时也介绍了如何用更简单的方式实现 DataBinding 和 ViewBinding。
40 |
41 | 感谢小伙伴们的建议，目前 Binding 已经适配了大量的场景，同时也提供了很多 DataBinding 和 ViewBinding 实战案例，如果你在使用过程中遇到 Binding 不兼容的场景，欢迎提 issue，我会尽快解决。
42 |
43 | **如果这个仓库对你有帮助，请在仓库右上角帮我 star 一下，非常感谢你的支持，同时也欢迎你提交 PR** ❤️❤️❤️
44 |
45 | **[Binding](https://github.com/hi-dhl/Binding) 具有以下优点：**
46 |
47 | * 支持在自定义 ViewGroup 使用 DataBinding 或者 ViewBinding
48 | * 提供了很多实战案例包含 `Ativity` 、 `Fragment` 、 `Dialog` 、 `Adapter` 、 `include` 、 `merge` 、 `ViewStub` 、 `Navigation` 、 数据双向绑定 等等场景
49 | * 简单的 API 只需要一行代码即可实现 DataBinding 或者 ViewBinding
50 | * 支持在 `Activity` 、`AppCompatActivity` 、`FragmentActivity` 、`Fragment` 、`Dialog` 中的使用 DataBinding 或者 ViewBinding
51 | * 支持在 `ListAdapter` 、 `PagedListAdapter` 、 `PagingDataAdapter` 、 `RecyclerView.Adapter` 中的使用 DataBinding 或者 ViewBinding
52 | * 支持在 Navigaion Fragment 管理框架、 BottomSheetDialogFragment 等等场景中使用 DataBinding 和 ViewBinding
53 | * 避免大量的模板代码
54 | * 避免内存泄露，具有生命周期感知能力，当生命周期处于 `onDestroyed()` 时会自动销毁数据

91 | ## 简单的 API
92 |
93 | Binding 统一封装了 DataBinding 和 ViewBinding， 提供了简单的 API 如下所示。
94 |
95 | **ViewBinding 中的使用**
96 |
97 | ```
98 | val binding: ActivityViewBindBinding by viewbind()
99 | ```
100 |
101 | **DataBinding 中的使用**
102 |
103 | ```
104 | val binding: ActivityDataBindBinding by databind(R.layout.activity_data_bind)
105 | 或者
106 | val binding: ActivityDataBindBinding by databind()
107 | ```
108 |
109 | 我们来看一下在 `Ativity` 、 `Fragment` 、 `Dialog` 、 `Adapter` 、 `include` 、 `merge` 、 `ViewStub` 、 `Navigation` 、 `ViewGroup` 、 数据双向绑定 等等场景中如何使用。
110 |
111 | ## 使用
112 |
113 | 在自定义 ViewGroup 中使用 DataBinding 和 ViewBinding，
114 |
115 | * ViewBinding 两种用法
116 | * 当根布局是非 merge 标签，使用此方法进行初始化 `val binding: LayoutViewCustomBinding by viewbind()`
117 | * 当根布局为 merge 标签，使用此方法进行初始化 `val binding: LayoutViewCustomBinding by viewbind(this)`
118 |
119 | * DataBinding 的使用
120 |
121 | ```
122 | val binding: LayoutViewCustomDataBinding by databind(R.layout.layout_view_custom_data)
123 | ```
124 |
125 | 详细的 Demo 示例如下所示。
126 |
127 | ```
128 | class ViewBindCustomView @JvmOverloads constructor(
129 | context: Context,
130 | attr: AttributeSet? = null,
131 | defStyleAttr: Int = 0,
132 | ) : LinearLayout(context, attr, defStyleAttr) {
133 |
134 | // ViewBinding
135 |
136 | // 当根布局为 merge 标签，使用此方法进行初始化
137 | val binding: LayoutViewCustomBinding by viewbind(this)
138 |
139 | // 当根布局是非 merge 标签，使用此方法进行初始化
140 | val binding: LayoutViewCustomBinding by viewbind()
141 |
142 | // DataBinding
143 | val binding: LayoutViewCustomDataBinding by databind(R.layout.layout_view_custom_data)
144 |
145 | init {
146 | with(binding) {
147 | result.setText("在自定义 ViewGroup 中使用 DataBinding 或者 ViewBinding")
148 | }
149 | }
150 | }
151 | ```
152 |
153 | 在 Adapter 中使用 DataBinding 和 ViewBinding，只需要在 ViewHolder 中添加 `by viewbind()` 或者 `by databind()` 即可，示例如下所示，[查看详细示例](https://github.com/hi-dhl/Binding/blob/main/app/src/main/java/com/hi/dhl/demo/binding/databind/list/ProductAdapter.kt)
154 |
155 | ```
156 | class ProductViewHolder(view: View) : RecyclerView.ViewHolder(view) {
157 |
158 | // 通过 DataBinding 绑定的 itemView
159 | val binding: RecycleItemProductBinding by databind()
160 |
161 | fun bindData(data: Product?, position: Int) {
162 | binding.apply {
163 | product = data
164 | executePendingBindings()
165 | }
166 | }
167 | }
168 |
169 | class ProductViewHolderHeader(view: View) : RecyclerView.ViewHolder(view) {
170 |
171 | // ViewBinding
172 | val binding: RecycleItemProductHeaderBinding by viewbind()
173 |
174 | fun bindData(data: Product?, position: Int) {
175 | binding.apply {
176 | name.text = "通过 ViewBinding 绑定的 head"
177 | }
178 | }
179 | }
180 | ```
181 |
182 |
183 | 在 `Activity` 、`AppCompatActivity` 、`FragmentActivity` 中使用，添加 `by viewbind()` 或者 `by databind(R.layout.activity_main)` 即可，示例如下所示。
184 |
185 | ```
186 | class MainActivity : AppCompatActivity() {
187 |
188 | // DataBinding
189 | val binding: ActivityMainBinding by databind(R.layout.activity_main)
190 |
191 | // ViewBinding
192 | val binding: ActivityMainBinding by viewbind()
193 | }
194 | ```
195 |
196 | 在 `Fragment` 中提供了两种方式：
197 |
198 | * 方式一：在 `onCreateView` 中使用，[查看详细示例](https://github.com/hi-dhl/Binding/tree/main/app/src/main/java/com/hi/dhl/demo/binding/navigation)
199 | * 方式二：在 `onViewCreated` 中使用，查看 [ViewBindFragment.kt](https://github.com/hi-dhl/Binding/blob/main/app/src/main/java/com/hi/dhl/demo/binding/viewbind/ViewBindFragment.kt) 和 [DataBindRecycleFragment.kt](https://github.com/hi-dhl/Binding/blob/main/app/src/main/java/com/hi/dhl/demo/binding/databind/list/DataBindRecycleFragment.kt)
200 |
201 | **方式一：不建议使用，建议直接使用方式二，详见 issue [#13](https://github.com/hi-dhl/Binding/issues/13)**
202 |
203 | ```
204 | class FragmentNav1 : Fragment() {
205 |
206 | // DataBinding
207 | val binding: FragmentMainBinding by databind()
208 |
209 | // ViewBinding
210 | val binding: FragmentMainBinding by viewbind()
211 |
212 | override fun onCreateView(
213 | inflater: LayoutInflater, container: ViewGroup?,
214 | savedInstanceState: Bundle?
215 | ): View {
216 | return binding.root
217 | }
218 | }
219 | ```
220 |
221 | **方式二：**
222 |
223 | ```
224 | class FragmentNav1 : Fragment(R.layout.fragment_main) {
225 |
226 | // DataBinding
227 | val binding: FragmentMainBinding by databind()
228 |
229 | // ViewBinding
230 | val binding: FragmentMainBinding by viewbind()
231 |
232 | override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
233 | super.onViewCreated(view, savedInstanceState)
234 | binding.apply { textView.setText("Binding") }
235 | }
236 | }
237 | ```
238 |
239 | 在 `Dialog` 中使用方式如下所示。
240 |
241 | ```
242 | class AppDialog(context: Context) : Dialog(context, R.style.AppDialog) {
243 |
244 | // DataBinding
245 | val binding: DialogAppBinding by databind(R.layout.dialog_data_binding)
246 |
247 | // ViewBinding
248 | val binding: DialogAppBinding by viewbind()
249 |
250 | override fun onCreate(savedInstanceState: Bundle?) {
251 | super.onCreate(savedInstanceState)
252 | binding.apply { result.setText("DialogAppBinding") }
253 | }
254 | }
255 | ```
256 |
257 | 或者添加具有生命周期感知的 `Dialog`。
258 |
259 | ```
260 | class AppDialog(context: Context,lifecycle: Lifecycle) : Dialog(context, R.style.AppDialog) {
261 |
262 | // DataBinding 监听生命周期
263 | val binding: DialogAppBinding by databind(R.layout.dialog_data_binding, lifecycle)
264 |
265 | // ViewBinding 监听生命周期
266 | val binding: DialogAppBinding by viewbind(lifecycle)
267 |
268 | override fun onCreate(savedInstanceState: Bundle?) {
269 | super.onCreate(savedInstanceState)
270 | binding.apply { result.setText("DialogAppBinding") }
271 | }
272 | }
273 | ```
274 |
275 | 扩展方法，支持 DataBinding 初始化的时候绑定数据，感谢 `@br3ant` 贡献，[查看详细示例](https://github.com/hi-dhl/Binding/blob/054aa169d8dd39023be55be589b67e8097702bd1/app/src/main/java/com/hi/dhl/demo/binding/databind/DatBindActivity.kt#L28-L33)
276 |
277 | ```
278 | val binding: ActivityDataBindBinding by databind(R.layout.activity_data_bind) {
279 | val account = Account()
280 | account.name = "test"
281 | this.account = account
282 | }
283 | ```
284 |
285 | 不想为某个布局生成 binding 类，将下面属性添加到布局文件的根视图中
286 |
287 | ```
288 |
289 |
290 | ```
291 |
292 | ### 混淆
293 |
294 | ```
295 | -keepclassmembers class ** implements androidx.viewbinding.ViewBinding {
296 | public static ** bind(***);
297 | public static ** inflate(***);
298 | }
299 | ```
