However I have found some information which defines what is a ButtonBar layout and when to use it. I tried myself to search about it, but to no avail.

ButtonBar layout does not seem to be featured anywhere in the official Android documentation.

There, it might be useful to setup a bottom button bar that follows the design guidelines, and have full control on the buttons (like enabling and disabling, things you can't do with an AlertDialog AFAIK). For example, AlertDialog and AlertDialog.Builder offer internal support for dialogs with buttons, but sometimes you just want to subclass DialogFragment or AppCompatDialogFragment for a better control. So, one possible use of this class, is when designing your own dialogs. When text labels exceed the maximum button width, use stacked buttons While you should go for stacked buttons when the single button is too large, or there's not enough room for both: Not exceed the maximum button width, such as the commonly used Side-by-side buttons are recommended when the text of each label does They make a distinction between side by side buttons and stacked buttons. I might add that this was clearly done to fit with the material design specifications about dialogs. P.S.: I used Android Studio of 2.0.0 Preview 4 and Gradle Plugin of 2.0.0-alpha3 and Android Support Library of 23.1.1 and Platform-tools of 23.1 and Build-tools of 23.0.2.Īs others pointed out, the class description tells exactly what it is: an extension of LinearLayout that automatically switches to vertical orientation when it can't fit its child views horizontally. So does somebody know ButtonBarLayout well? But I didn't really understand what it is used for.

When it changes, orientation of this layout would be changed. I noticed the variable of private boolean mAllowStacking.What can we get from ButtonBarLayout literally and how should we use it?.At the same time, ButtonBarLayout is inherited from LinearLayout. So I thought maybe 7.widget.ButtonBarLayout came from .ButtonBarLayout after the internal ButtonBarLayout was through tests and released. I tried to read source codes of both, I found that they are the same except package name. In the meantime, I found two ButtonBarLayout when I search ButtonBarLayout everywhere in Android Studio, one is 7.widget.ButtonBarLayout and the other is .ButtonBarLayout. I tried to search it on the internet, but nothing was found, even on the official development documents site. When I developed, I found a new widget called 7.widget.ButtonBarLayout unexpectedly.
