Android: Can we even "design" our own widgets and layouts?

Question

I read this here:

Android provides a number of ready-made views that you can use to design and organize your layout. "Widgets" are views that provide a visual (and interactive) elements for the screen, such as a button, text field, checkbox, or just an image. "Layouts" are views derived from ViewGroup that provide a unique layout model for its child views, such as a linear layout, a grid layout, or relative layout. You can also subclass the View and ViewGroup classes (or existing subclasses) to create your own widgets and layouts and apply them to your activity layout.

If I am not wrong, this means people can even design their own widgets and layouts? Does that ever happen? Any examples?

Answer 1

Yes.

Does that ever happen?

Yes.

Any examples?

There are hundreds of examples out on the Android Arsenal alone. Just looking at a couple of columns of the recent items, there are the following custom widgets and containers:

• material-drawer
• Material Design Android Library
• StarBar
• AndroidProgressLayout
• DiscreteSeekBar
• Android-SingleInputForm
• SunDate Picker
