49 | } 50 | ``` 51 | 52 | 当然也可以直接标记你的JavaBean，来直接保存此类。那么参数名为类名的首字母小写：seekBar 53 | ```java 54 | @LiveData 55 | public class SeekBar { 56 | 57 | Integer value; 58 | } 59 | ``` 60 | 61 | 使用`@LiveData(classType = LiveDataClassType.LIST)`可以指定对应的数据集合类型 62 | 63 | Build -- > Make Project 会生成代码如下： 64 | 65 | ```java 66 | public class SeekBarViewModel extends ViewModel { 67 | private MutableLiveData mValue; 68 | 69 | public MutableLiveData getValue() { 70 | if (mValue == null) { 71 | mValue = new MutableLiveData<>(); 72 | } 73 | return mValue; 74 | } 75 | 76 | public Integer getValueValue() { 77 | return getValue().getValue(); 78 | } 79 | 80 | public void setValue(Integer mValue) { 81 | if (this.mValue == null) { 82 | return; 83 | } 84 | this.mValue.setValue(mValue); 85 | } 86 | 87 | public void postValue(Integer mValue) { 88 | if (this.mValue == null) { 89 | return; 90 | } 91 | this.mValue.postValue(mValue); 92 | } 93 | } 94 | 95 | ``` 96 | 97 | 如果想使用`AndroidViewModel`的话，可以添加`@AndroidViewModel`注解 98 | 99 | ```java 100 | @AndroidViewModel 101 | public class SeekBar { 102 | 103 | @LiveData 104 | Integer value; 105 | } 106 | ``` 107 | 108 | 自定义`LiveData`类型 109 | 110 | ```java 111 | public class Single { 112 | 113 | @LiveData(type = LiveDataType.OTHER, liveDataType = XXXLiveData.class) 114 | Integer value; 115 | } 116 | 117 | ``` 118 | 119 | 生成代码提供了LiveData的常用操作。 120 | 121 | - `setXXX()`要在主线程中调用。 122 | 123 | - `postXXX()`既可在主线程也可在子线程中调用。 124 | 125 | - `getXXX()`用于获取观察者。 126 | 127 | - `getXXXValue()`可以获取保存的数据。 128 | 129 | - `addSource()`用于监听LiveData。(MediatorLiveData专用) 130 | 131 | - `removeSource()`移除监听的LiveData。(MediatorLiveData专用) 132 | 133 | ### 1. 普通使用方法 134 | 135 | 一般情况下可以直接使用它。比如： 136 | 137 | ```java 138 | public class TestFragment extends Fragment { 139 | 140 | private SeekBar mSeekBar; 141 | 142 | @BindViewModel(isShare = true) //<--标记需要绑定的ViewModel 143 | SeekBarViewModel mSeekBarViewModel; 144 | 145 | @Override 146 | public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 147 | // Inflate the layout for this fragment 148 | View root = inflater.inflate(R.layout.fragment_test, container, false); 149 | mSeekBar = root.findViewById(R.id.seekBar); 150 | Saber.bind(this); // <--这里绑定ViewModel 151 | subscribeSeekBar(); 152 | return root; 153 | } 154 | 155 | private void subscribeSeekBar() { 156 | 157 | mSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 158 | @Override 159 | public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { 160 | if (fromUser) { 161 | mSeekBarViewModel.setValue(progress); 162 | } 163 | } 164 | ...... 165 | }); 166 | } 167 | 168 | @OnChange(model = "mSeekBarViewModel") //<--接收变化的ViewModel变量名 169 | void setData(Integer value){ //注意这里使用 @LiveData 标记的参数名 170 | if (value != null) { 171 | mSeekBar.setProgress(value); 172 | } 173 | } 174 | } 175 | ``` 176 | 177 | `@BindViewModel`用于绑定ViewModel。 178 | 179 | `@OnChange(model = "xxx")`用于接收指定ViewModel的数据变化，可以不设置，默认model名称为mViewModel。 180 | 181 | 如果需要`Fragment`之间数据共享，需要`@BindViewModel(isShare = true)`，当然也要保证传入相同的key值。默认key值是类的规范名称，也就是包名加类名。 182 | 183 | ![这里写图片描述](https://img-blog.csdn.net/20180619100304754?watermark/2/text/aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzE3NzY2MTk5/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70) 184 | 185 | 所以一旦需要互通的Fragment类名或包名不一致，就无法数据共享。这时可以指定key值：`@BindViewModel(key = "value")` 186 | 187 | ### 2. 事件总线使用方法，[详细用法参看LiveEventBus](https://github.com/JeremyLiao/LiveEventBus) 188 | 189 | ```java 190 | @LiveEventBus(model = "key_name") 191 | void liveDataBus(String value){ 192 | 193 | } 194 | ``` 195 | 196 | 发送： 197 | 198 | ```java 199 | LiveEventBus.get().with("key_name").postValue("value"); 200 | ``` 201 | 202 | 203 | 更多的使用方法可以参看本项目demo。 204 | 205 | ### 3.Kotlin环境使用注意事项 206 | 207 | 1.将以下代码添加到 `build.gradle` 文件中，保证生成代码的正确性。 208 | 209 | ```gradle 210 | 211 | kapt { 212 | correctErrorTypes = true 213 | } 214 | 215 | ``` 216 | 217 | 2.Kotlin默认会生成set/get方法，并把属性设置为`private` 所以只要保证Kotlin中字段可见性不是`private`即可，简单解决可以在字段上添加 `@JvmField`，也可以使用`lateinit`. 218 | 219 | ```kotlin 220 | 221 | @BindViewModel 222 | lateinit var mViewModel: TestViewModel 223 | 224 | //或 225 | 226 | @JvmField 227 | @BindViewModel 228 | var mViewModel: TestViewModel? = null 229 | ``` 230 | 231 | ## TODO 232 | 233 | 1.~~因为现有的`@OnChange`注解承载的功能过多，不易使用。后面会将`EventBus`功能从中提出，添加一个新的注解（或许叫做`@LiveEventBus`）。~~ 234 | 235 | 2.有什么好的建议或者功能欢迎提Issues。 236 | 237 | ## 版本变化 238 | 239 | - [点击查看](https://github.com/simplezhli/Saber/releases) 240 | 241 | ## Thanks For 242 | 243 | - [butterknife](https://github.com/JakeWharton/butterknife) 244 | 245 | - [在 SnackBar，Navigation 和其他事件中使用 LiveData](https://juejin.im/post/5b2b1b2cf265da5952314b63) 246 | 247 | - [LiveEventBus](https://github.com/JeremyLiao/LiveEventBus) 248 | 249 | ## License 250 | 251 | Copyright 2018 simplezhli 252 | 253 | Licensed under the Apache License, Version 2.0 (the "License");
