XML
Include the widget into your xml layout like this
<com.github.okdroid.checkablechipview.CheckableChipView
android:id="@+id/chip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Pie Cake" />The following xml attributes are supported
| Attribute | Description |
|---|---|
android:text | The text to display |
android:textColor | The default text color |
android:color | The color of the indicator dot as well as the background color when the widget is checked |
android:background | The default background color |
android:checked | The checked state of the widget, either true or false |
app:ccv_outlineColor | The color of the outline |
app:ccv_outlineCornerRadius | The corner radius of the outline, in dp. Defaults to a pill shape if not set |
app:ccv_outlineWidth | The stroke width of the outline, in dp |
app:ccv_checkedTextColor | The text color when the widget is checked |
app:ccv_foreground | The foreground drawable to display |
In code
The state of the widget can be observed like this
chip.onCheckedChangeListener = { view: CheckableChipView, isChecked: Boolean ->
// do your logic here
}To switch between checked/unchecked state programatically with animation, use the following method:
chip.setCheckedAnimated(checked = true) {
// onAnimationEnd callback
}Plus, there are following methods at your service for changing the state without animation:
if (!chip.isChecked) {
chip.isChecked = true
}
chip.toggle() // toggles between statesAcknowledgements
Thanks to the team behind the Google I/O app. Thank you for open sourcing the code and letting others reuse and learn from it.
Thanks to Nick Butcher for the initial implementation in the I/O app.
