🎺 A collection of Jetpack Compose libraries, which are compatible with custom views for Android.














## Balloon

**Orchestra Balloon** was deprecated. Now Balloon supports Jetpack Compose, so please check out [Balloon in Jetpack Compose](https://github.com/skydoves/balloon#balloon-in-jetpack-compose-1).



## ColorPicker

**Orchestra ColorPicker** allows you to build color picker for getting colors from any images by tapping on the desired color for Jetpack Compose. This is a Jetpack Compose compatible package of [ColorPickerView](https://github.com/skydoves/colorpickerview).



### Download



[![Maven Central](https://img.shields.io/maven-central/v/com.github.skydoves/orchestra-colorpicker.svg?label=Maven%20Central)](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22orchestra-colorpicker%22)


Add the dependency below to your **module**'s `build.gradle` file:

```gradle

dependencies {

    implementation "com.github.skydoves:orchestra-colorpicker:$version"

}

```






### Usage

`ColorPicker` composable implements a color picker with `AlphaSlideBar` and `BrightnessSlideBar`. We can create an alpha sidebar and brightness sidebar for changing saturation and lightness by tapping on the desired color. They should be used in `children` inner composable in `ColorPicker`, and they receive a `colorPickerView` as a parameter.



```kotlin

val (selectedColor, setSelectedColor) 

      = remember { mutableStateOf(ColorEnvelope(0)) }

ColorPicker(

    modifier = Modifier.fillMaxWidth().height(400.dp),

    onColorListener = { envelope, _ ->

      setSelectedColor(envelope)

    },

    initialColor = purple500,

    children = { colorPickerView ->

      Column(modifier = Modifier.padding(top = 32.dp)) {

        Box(modifier = Modifier.padding(vertical = 6.dp)) {

          AlphaSlideBar(

            modifier = Modifier.fillMaxWidth().height(30.dp)

              .clip(RoundedCornerShape(4.dp)),

            colorPickerView = colorPickerView

          )

        }

        Box(modifier = Modifier.padding(vertical = 6.dp)) {

          BrightnessSlideBar(

            modifier = Modifier.fillMaxWidth().height(30.dp)

              .clip(RoundedCornerShape(4.dp)),

            colorPickerView = colorPickerView

          )

        }

      }

    }

  )

```



### AlphaTileBox

In a normal View, it can not represent ARGB colors accurately. Because a color will be mixed with the parent's background-color. For resolving it we can use `AlphaTileBox` composable. `AlphaTileBox` composable reflects ARGB colors.

```kotlin

AlphaTileBox(

  modifier = modifier.constrainAs(square) {

    bottom.linkTo(parent.bottom)

    centerHorizontallyTo(parent)

  }.size(64.dp).clip(RoundedCornerShape(4.dp))

) {

  it.setBackgroundColor(selectedColor.color)

}

```



## Spinner

**Orchestra Spinner** allows you to build a lightweight dropdown popup spinner, fully customizable with an arrow and animations for Jetpack Compose. This is a Jetpack Compose compatible package of [PowerSpinner](https://github.com/skydoves/powerspinner).



### Download



[![Maven Central](https://img.shields.io/maven-central/v/com.github.skydoves/orchestra-spinner.svg?label=Maven%20Central)](https://search.maven.org/search?q=g:%22com.github.skydoves%22%20AND%20a:%22orchestra-spinner%22)


Add the dependency below to your **module**'s `build.gradle` file:

```gradle

dependencies {

    implementation "com.github.skydoves:orchestra-spinner:$version"

}

```






### Usage

`Spinner` composable implements a lightweight dropdown popup spinner. Here is an example for creating a spinner using a string array resource. We should use the String generic type for creating a spinner when we us a string array resource.



```kotlin

 val (selectedItem, setSelectedItem) 

      = remember { mutableStateOf("Choose a question") }

 Spinner(

      text = selectedItem0,

      modifier = Modifier.fillMaxWidth().padding(16.dp)

        .background(blue200)

        .align(Alignment.CenterHorizontally),

       itemListRes = R.array.list_spinner,

      style = MaterialTheme.typography.body2,

      properties = SpinnerProperties(

        color = Color.White,

        textAlign = TextAlign.Center,

        showDivider = true,

        dividerColor = white87,

        overflow = TextOverflow.Ellipsis,

        maxLines = 1,

        spinnerPadding = 16.dp,

        spinnerBackgroundColor = MaterialTheme.colors.onBackground,

      ),

      onSpinnerItemSelected = { index, item ->

        setSelectedItem(item)

      }

    )

```

Here is an another example using a List for creating a spinner. In this case, we don't need to decide a generic type of Spinner.



```kotlin

 val coffeeList = remember { listOf("Americano", "Cold Brew", "Espresso", "Latte") }

 val (selectedItem1, setSelectedItem1) = remember { mutableStateOf("Choose your coffee") }

 Spinner(

      text = selectedItem1,

      modifier = Modifier.fillMaxWidth().padding(16.dp)

        .background(amber700)

        .align(Alignment.CenterHorizontally),

      itemList = coffeeList,

      style = MaterialTheme.typography.body2,

      properties = SpinnerProperties(

        color = Color.White,

        textAlign = TextAlign.Center,

        dividerColor = white87,

        overflow = TextOverflow.Ellipsis,

        maxLines = 1,

        spinnerPadding = 16.dp,

        spinnerBackgroundColor = MaterialTheme.colors.onBackground,

      ),

      onSpinnerItemSelected = { index, item ->

        setSelectedItem1(item)

      }

    )

```
