8 | 2、Support Priority
9 | 3、Support Task grouping
10 | 4、Support lifecycle
11 | 5、Support chain invocation 12 | 13 | 14 | 15 | ## Prepare 16 | 17 | 1. Initialization(optional） 18 | 19 | ```kotlin 20 | LogProxy.init(object : TaskLogger { 21 | override val isDebug: Boolean 22 | get() = BuildConfig.DEBUG 23 | 24 | override fun e(tag: String, e: Throwable) { 25 | Log.e(tag, e.message, e) 26 | } 27 | }) 28 | ``` 29 | 30 | 2. Notify Lifecycle Events 31 | 32 | ```kotlin 33 | abstract class BaseActivity : Activity() { 34 | override fun onDestroy() { 35 | super.onDestroy() 36 | LifecycleManager.notify(this, LifeEvent.DESTROY) 37 | } 38 | 39 | override fun onPause() { 40 | super.onPause() 41 | LifecycleManager.notify(this, LifeEvent.HIDE) 42 | } 43 | 44 | override fun onResume() { 45 | super.onResume() 46 | LifecycleManager.notify(this, LifeEvent.SHOW) 47 | } 48 | } 49 | ``` 50 | 51 | 52 | ## How to use 53 | ### 1、Standard usage 54 | 55 | Just like AsyncTask: 56 | 57 | ```kotlin 58 | override fun onCreate(savedInstanceState: Bundle?) { 59 | // ... 60 | TestTask() 61 | .priority(Priority.IMMEDIATE) 62 | .host(this) 63 | .execute("hello") 64 | } 65 | 66 | private inner class TestTask: UITask(){ 67 | override fun generateTag(): String { 68 | // Normally, you don't need to override this function 69 | return "custom tag" 70 | } 71 | 72 | override fun onPreExecute() { 73 | result_tv.text = "running" 74 | } 75 | 76 | override fun doInBackground(vararg params: String): String? { 77 | for (i in 0..100 step 2) { 78 | Thread.sleep(10) 79 | publishProgress(Integer(i)) 80 | } 81 | return "result is：" + params[0].toUpperCase() 82 | } 83 | 84 | override fun onProgressUpdate(vararg values: Integer) { 85 | val progress = values[0] 86 | progress_bar.progress = progress.toInt() 87 | progress_tv.text = "$progress%" 88 | } 89 | 90 | override fun onPostExecute(result: String?) { 91 | result_tv.text = result 92 | } 93 | 94 | override fun onCancelled() { 95 | showTips("Task cancel ") 96 | } 97 | } 98 | ``` 99 | 100 | 101 | ### 2、Executor 102 | 103 | ``` 104 | TaskCenter.io.execute{ 105 | // do something 106 | } 107 | 108 | TaskCenter.laneIO.execute("tag", { 109 | // do something 110 | }) 111 | 112 | val serialExecutor = PipeExecutor(1) 113 | serialExecutor.execute{ 114 | // do something 115 | } 116 | 117 | TaskCenter.serial.execute ("your tag", { 118 | // do something 119 | }) 120 | ``` 121 | 122 | ### 3、For RxJava 123 | 124 | ```kotlin 125 | object TaskSchedulers { 126 | val io: Scheduler by lazy { Schedulers.from(TaskCenter.io) } 127 | val computation: Scheduler by lazy { Schedulers.from(TaskCenter.computation) } 128 | val single by lazy { Schedulers.from(PipeExecutor(1)) } 129 | } 130 | ``` 131 | 132 | ```kotlin 133 | Observable.range(1, 8) 134 | .subscribeOn(TaskSchedulers.computation) 135 | .subscribe { Log.d(tag, "number:$it") } 136 | ``` 137 | 138 | ### 4、Chain invocation 139 | ```kotlin 140 | override fun onCreate(savedInstanceState: Bundle?) { 141 | val task = ChainTask() 142 | task.tag("ChainTest") 143 | .preExecute { result_tv.text = "running" } 144 | .background { params -> 145 | for (i in 0..100 step 2) { 146 | // do something 147 | task.publishProgress(i) 148 | } 149 | "result is：" + (params[0] * 100) 150 | } 151 | .progressUpdate { values -> 152 | val progress = values[0] 153 | progress_bar.progress = progress 154 | progress_tv.text = "$progress%" 155 | } 156 | .postExecute { result_tv.text = it } 157 | .cancel { showTips("ChainTask cancel") } 158 | .priority(Priority.IMMEDIATE) 159 | .host(this) 160 | .execute(3.14) 161 | } 162 | ``` 163 | 164 | ## Link 165 | https://www.jianshu.com/p/8afb6cf64eec 166 | 167 | 168 | 169 | ## License 170 | See the [LICENSE](LICENSE.md) file for license rights and
