## KotlinAndroidSample ### 1. NetWork with [Kotlin] + [OkHttp] + [RxJava] / [RxAndroid] Request url("https://github.com/wangjiegulu") and update UI: ```Kotlin "https://github.com/wangjiegulu".request().get().rxExecute() .map({ r -> r.body().string() }) .observeOnMain() .subscribeSafeNext { result -> Log.d(TAG, "request result: $result"); resultTv.setText("Http request succeed, see log") } ``` ### 2. Inject views & events with [AndroidInject] library Inject "tv"(TextView) view and inject click event of the button. ```Kotlin @AILayout(R.layout.activity_inject) public class InjectWithAIActivity : BaseActivity(){ @AIView(R.id.activity_inject_tv) private var tv: TextView? = null; override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) tv?.setText("TextView inject succeed") } @AIClick(R.id.activity_inject_btn) public fun onClick(view: View){ when(view.getId()){ R.id.activity_inject_btn -> toast("clicked, button inject succeed!") } } } ``` ### 3. Database operation with [RapidORM] - Checkout `feature-rapidorm` branch, - Checkout [RapidORM] library, - `setting.gradle` Configuration: ```java include ':app', ':RapidORM' project(":RapidORM").projectDir = new File(settingsDir, "[Your relative path of RapidORM library]"); ``` ```Kotlin @Table public data class Person : Serializable{ @Column(primaryKey = true) var id: Int? = null; @Column var name: String? = null; @Column var email: String? = null; @Column var student: Boolean? = null; } // Get Person dao var personDao = DatabaseFactory.getDao(javaClass<PersonDaoImpl>()); // insert var p = Person() p.id = 100023L; p.name = "wangjie" p.email = "tiantian.china.2@gmail.com" p.student = true; personDao.insert(generatePerson()); // delete personDao.deleteBuilder() .setWhere(Where.eq("student", true)) .delete(personDao) // update p.student = false personDao.update(p) // query personDao.queryAll() ``` [AndroidInject]: https://github.com/wangjiegulu/androidInject [Kotlin]: http://kotlinlang.org/ [OkHttp]: https://github.com/square/okhttp [RxJava]: https://github.com/ReactiveX/RxJava [RxAndroid]: https://github.com/ReactiveX/RxAndroid [RapidORM]: https://github.com/wangjiegulu/RapidORM
