Android sample with kotlin.

KotlinAndroidSample

1. NetWork with Kotlin + OkHttp + RxJava / RxAndroid

Request url("https://github.com/wangjiegulu") and update UI:

"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.

@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:

include ':app', ':RapidORM'
project(":RapidORM").projectDir = new File(settingsDir, "[Your relative path of RapidORM library]");

@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 = "[e-mail]"
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()
