[![](https://jitpack.io/v/sasa-nori/common-ktx.svg)](https://jitpack.io/#sasa-nori/common-ktx)

## Prerequisites

* must minSdkVersion is 23 over

## install

```build.gradle
allprojects {
repositories {
google()
mavenCentral()

maven { url 'https://jitpack.io' } // add
maven { url "https://maven.pkg.jetbrains.space/public/p/kotlinx-html/maven" } // add
}
}

```
```app/build.gradle
dependencies {
implementation "com.github.sasa-nori:common-ktx:$latestVersion"
}
```

## Kdoc

[Document](https://sasa-nori.github.io/common-ktx/)

## Example

[CommonKtx-Example](https://github.com/sasa-nori/CommonKtx-Example)

## Tips

### Object to JSON String

Add Moshi codegen

```
kapt "com.squareup.moshi:moshi-kotlin-codegen:1.9.2"
```

Added `@JsonClass(generateAdapter = true)` to Class top

```
@JsonClass(generateAdapter = true)
data class Test(val first: String, val second: String)
```

```
Test("first", "second").toJsonString()
```

## Usage

### SingleClick

default timeout is 500ms

```
button.setOnSingleClickListener {
// run
}
```

to custom

```
button.setOnSingleClickListener(300, { view->
// run
})
```

### Check RuntimePermission

```
val permissions = arrayOf(
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
)
if (hasPermission(permissions)) {
// run
} else {
requestPermissions(permissions, REQUEST_CODE)
}
```

### SharedPreferences

```
class Preferences(context: Context) : SharedPrefDelegated(context) {
var isFirstLaunch: Boolean by pref(default = true)
}
```

```
val pref = Preferences(this)
val isFirstLaunch = when (pref.isFirstLaunch) {
true -> {
pref.isFirstLaunch = false
true
}
else -> false
}
```

### LiveData (One Shot Event)


- ViewModel

```
class TestViewModel() : ViewModel {
private var testData = MutableLiveData>()

var testDataLiveData: LiveData>() = testData

fun postData() {
testData.postValue(Event("test"))
}

}

```

- Activity

```
class TestActivity(): Activity {

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

testViewModel.testDataLiveData.observer(this, EventObserver {
Timber.d(it)
})
}
}

```

### SoundPool

```
class TestActivity(): Activity {

private var soundPathList: MutableList = mutableListOf()

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(layout.activity_main)
setSupportActionBar(toolbar)

fab.setOnSingleClickListener { view ->
view?.let {
SoundPool.play(soundPathList.first())
}
}

lifecycleScope.launch {
soundPathList = loadSoundPool(mutableListOf(R.raw.one))
}
}

}
```

### LiveData (Unit Test)

see [MainViewModelTest.kt](https://github.com/sasa-nori/common-ktx/blob/develop/example/src/test/java/net/newstyleservice/example/MainViewModelTest.kt)

```
@Test
fun requestApi() = runBlocking {
// given
val answer = mutableListOf(Shikure(0, "", "", 0, 0))
`when`(apiService.getShikure()).thenReturn(answer)
val liveDataTestObserver = target.getShikureList().testObserver()

// when
target.requestApi(apiService)

// than
val result = liveDataTestObserver.observedValues.first()
assertThat(result?.getContentIfNotHandled()).isEqualTo(answer)
}
```
