Android Button Icon Only. Android:drawableleft doesn't work for me (maybe it would, but i don't know how to set a max height to the icon). Image icon can add via android:drawableleft=”@drawable/your image name” tag.
The mdc icon button can be used with both < button > and < a > tags. Android:drawableleft doesn't work for me (maybe it would, but i don't know how to set a max height to the icon). A button consists of text or an icon (or both text and an icon) that communicates what action occurs when the user touches it.
Now invoke the normal fab button.
You can add a basic toggle button to your layout with the togglebutton object. Also known as togglebutton, this used to host buttons with checkable behavior. If you don't update your launcher icon with the necessary layers, the icon doesn't look consistent with other icons that the system ui displays, and doesn't support visual effects. Adaptive icons support a variety of visual effects.
