Orchestra

🎺 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.

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.

Download

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

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.

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.

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.

Download

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

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.

 val (selectedItem, setSelectedItem) 
      = remember { mutableStateOf("Choose a question") }
 Spinner<String>(
      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.

 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)
      }
    )
