View(Context, IAttributeSet)
Constructor that is called when inflating a view from XML.
[Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;)V", "")]
public View (Android.Content.Context? context, Android.Util.IAttributeSet? attrs);
[<Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;)V", "")>]
new Android.Views.View : Android.Content.Context * Android.Util.IAttributeSet -> Android.Views.View
Parameters
- 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 tag that is inflating the view.
- Attributes
Remarks
Constructor that is called when inflating a view from XML. This is called when a view is being constructed from an XML file, supplying attributes that were specified in the XML file. This version uses a default style of 0, so the only attribute values applied are those in the Context's Theme and the given AttributeSet.
The method onFinishInflate() will be called after all children have been added.

Applies to
View(Context, IAttributeSet, Int32)
Perform inflation from XML and apply a class-specific base style from a theme attribute.
[Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;I)V", "")]
public View (Android.Content.Context? context, Android.Util.IAttributeSet? attrs, int defStyleAttr);
[<Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;I)V", "")>]
new Android.Views.View : Android.Content.Context * Android.Util.IAttributeSet * int -> Android.Views.View
Parameters
- 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 tag that is inflating the view.
- defStyleAttr
- Int32
An attribute in the current theme that contains a reference to a style resource that supplies default values for the view. Can be 0 to not look for defaults.
- Attributes
Remarks
Perform inflation from XML and apply a class-specific base style from a theme attribute. This constructor of View allows subclasses to use their own base style when they are inflating. For example, a Button class's constructor would call this version of the super class constructor and supply R.attr.buttonStyle
for <var>defStyleAttr</var>; this allows the theme's button style to modify all of the base view attributes (in particular its background) as well as the Button class's attributes.

Applies to
View(Context, IAttributeSet, Int32, Int32)
Perform inflation from XML and apply a class-specific base style from a theme attribute or style resource.
[Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;II)V", "")]
public View (Android.Content.Context? context, Android.Util.IAttributeSet? attrs, int defStyleAttr, int defStyleRes);
[<Android.Runtime.Register(".ctor", "(Landroid/content/Context;Landroid/util/AttributeSet;II)V", "")>]
new Android.Views.View : Android.Content.Context * Android.Util.IAttributeSet * int * int -> Android.Views.View
Parameters
- 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 tag that is inflating the view.
- defStyleAttr
- Int32
An attribute in the current theme that contains a reference to a style resource that supplies default values for the view. Can be 0 to not look for defaults.
- defStyleRes
- Int32
A resource identifier of a style resource that supplies default values for the view, used only if defStyleAttr is 0 or can not be found in the theme. Can be 0 to not look for defaults.
- Attributes
Remarks
Perform inflation from XML and apply a class-specific base style from a theme attribute or style resource. This constructor of View allows subclasses to use their own base style when they are inflating.
When determining the final value of a particular attribute, there are four inputs that come into play: <ol> <li>Any attribute values in the given AttributeSet. <li>The style resource specified in the AttributeSet (named "style"). <li>The default style specified by <var>defStyleAttr</var>. <li>The default style specified by <var>defStyleRes</var>. <li>The base values in this theme. </ol>
Each of these inputs is considered in-order, with the first listed taking precedence over the following ones. In other words, if in the AttributeSet you have supplied <Button * textColor="#ff000000">
, then the button's text will <em>always</em> be black, regardless of what is specified in any of the styles.
