In android, we can change the color of the drawable by using setColorFilter method. How do we do that in HarmonyOS?

setColorFilter(Color) is not directly supported in HMOS. But you may check the below callback in ohos.agp.components.element.Element class,

public void setColorMatrix​(ColorMatrix matrix)

which will also change the color of the element(which is equivalent to drawable in android). Please note, here you need to pass the ColorMatrix object as the argument. Please check this documentation for more info``
