Two thumbs with the slider of Material component for android?

Question

on the sliders presentation of the Material.io website they show the double thumbs slider below, but I can't find how to enable it, and I didnt really find any docs. Is it available for the android component?

Answer 1

You can use the Material Components Library.
Add the RangeSlider component in your layout. Something like:

    <com.google.android.material.slider.RangeSlider
        android:id="@+id/slider_multiple_thumbs"            
        android:valueFrom="0"
        android:valueTo="10"
        ../>

Then use the method setValues():

RangeSlider slider = findViewById(R.id.slider_multiple_thumbs);
slider.setValues(1.0f,5.0f);

The final result:

Note: This requires a minimum of version 1.2.0-beta01

Pls note that:

• each value must be greater or equal to valueFrom, and less or equal to valueTo. If that is not the case, an IllegalArgumentException will be thrown.
• if the slider is in discrete mode, the values must be set to a value that falls on a tick. if that is not the case, an IllegalArgumentException will be thrown.

With Compose you can use the RangeSlider:

    var sliderPosition by remember { mutableStateOf(0f..100f) }

    RangeSlider(
        modifier = Modifier.semantics { contentDescription = "Localized Description" },
        value = sliderPosition,
        onValueChange = { sliderPosition = it },
        valueRange = 0f..100f,
        onValueChangeFinished = {
            // launch some business logic update with the state you hold
            // viewModel.updateSelectedSliderValue(sliderPosition)
        },
    )

It is now available in the alpha-05-release: material-components Use it by calling setValues() with two values to enable two thumbs.

[2022 Update]

Now it exists RangeSlider.

import androidx.compose.material.RangeSlider
import androidx.compose.material.Text
import androidx.compose.runtime.mutableStateOf
import androidx.compose.runtime.remember

var sliderPosition by remember { mutableStateOf(0f..100f) }
Text(text = sliderPosition.toString())
RangeSlider(
    values = sliderPosition,
    onValueChange = { sliderPosition = it },
    valueRange = 0f..100f,
    onValueChangeFinished = {
        // launch some business logic update with the state you hold
        // viewModel.updateSelectedSliderValue(sliderPosition)
    },
)
