Button(Context, IAttributeSet)
LayoutInflater calls this constructor when inflating a Button from XML.
[Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;)V", "")]
public Button (Android.Content.Context? context, Android.Util.IAttributeSet? attrs);[<Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;)V", "")>]
new Android.Widget.Button : Android.Content.Context * Android.Util.IAttributeSet -> Android.Widget.ButtonParameters
- context
- Context
The Context the view is running in, through which it can access the current theme, resources, etc.
- attrs
- IAttributeSet
The attributes of the XML Button tag being used to inflate the view.
- Attributes
Remarks
LayoutInflater calls this constructor when inflating a Button from XML. The attributes defined by the current theme's android.R.attr#buttonStyle android:buttonStyle override base view attributes.
You typically do not call this constructor to create your own button instance in code. However, you must override this constructor when creating custom views.

Button(Context, IAttributeSet, Int32)
This constructor allows a Button subclass to use its own class-specific base style from a theme attribute when inflating.
[Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;I)V", "")]
public Button (Android.Content.Context? context, Android.Util.IAttributeSet? attrs, int defStyleAttr);[<Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;I)V", "")>]
new Android.Widget.Button : Android.Content.Context * Android.Util.IAttributeSet * int -> Android.Widget.ButtonParameters
- context
- Context
The Context the Button is running in, through which it can access the current theme, resources, etc.
- attrs
- IAttributeSet
The attributes of the XML Button tag that is inflating the view.
- defStyleAttr
- Int32
The resource identifier of an attribute in the current theme whose value is the the resource id of a style. The specified style’s attribute values serve as default values for the button. Set this parameter to 0 to avoid use of default values.
- Attributes
Remarks
This constructor allows a Button subclass to use its own class-specific base style from a theme attribute when inflating. The attributes defined by the current theme's defStyleAttr override base view attributes.
For Button's base view attributes see android.R.styleable#Button Button Attributes, android.R.styleable#TextView TextView Attributes, android.R.styleable#View View Attributes.
