<top.defaults.view.ColorPickerView
android:id="@+id/colorPicker"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:enableAlpha="true"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
See

// use the color
});
- Set initial color:
colorPickerView.setInitialColor(0x7F313C93);
- Reset to initial color:
