`int`	`FOCUS_AFTER_DESCENDANTS` This view will get focus only if none of its descendants want it.
`int`	`FOCUS_BEFORE_DESCENDANTS` This view will get focus before any of its descendants.
`int`	`FOCUS_BLOCK_DESCENDANTS` This view will block any of its descendants from getting focus, even if they are focusable.
`int`	`LAYOUT_MODE_CLIP_BOUNDS` This constant is a `layoutMode`.
`int`	`LAYOUT_MODE_OPTICAL_BOUNDS` This constant is a `layoutMode`.
`int`	`PERSISTENT_ALL_CACHES` This constant was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11.

In the rare cases where caching layers are useful, such as for alpha animations, `View.setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `View.draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `View.setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `View.draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

`Bitmap`	`getDrawingCache()` This method was deprecated in API level 28. The view drawing cache was largely made obsolete with the introduction of hardware-accelerated rendering in API 11. With hardware-acceleration, intermediate cache layers are largely unnecessary and can easily result in a net loss in performance due to the cost of creating and updating the layer. In the rare cases where caching layers are useful, such as for alpha animations, `setLayerType(int, android.graphics.Paint)` handles this with hardware rendering. For software-rendered snapshots of a small part of the View hierarchy or individual Views it is recommended to create a `Canvas` from either a `Bitmap` or `Picture` and call `draw(android.graphics.Canvas)` on the View. However these software-rendered usages are discouraged and have compatibility issues with hardware-only rendering features such as `Config.HARDWARE` bitmaps, real-time shadows, and outline clipping. For screenshots of the UI for feedback reports or unit testing the `PixelCopy` API is recommended.

`View`	The view corresponding to the currently selected item, or null if nothing is selected

onProvideAutofillStructure

Added in API level 26

public void onProvideAutofillStructure (ViewStructure structure, 
                int flags)

Populates a ViewStructure to fullfil an autofill request.

The structure should contain at least the following properties:

Autofill id (ViewStructure.setAutofillId(AutofillId, int)).
Autofill type (ViewStructure.setAutofillType(int)).
Autofill value (ViewStructure.setAutofillValue(AutofillValue)).
Whether the data is sensitive (ViewStructure.setDataIsSensitive(boolean)).

It's also recommended to set the following properties - the more properties the structure has, the higher the chances of an AutofillService properly using the structure:

Autofill hints (ViewStructure.setAutofillHints(String[])).
Autofill options (ViewStructure.setAutofillOptions(CharSequence[])) when the view can only be filled with predefined values (typically used when the autofill type is AUTOFILL_TYPE_LIST).
Resource id (ViewStructure.setId(int, String, String, String)).
Class name (ViewStructure.setClassName(String)).
Content description (ViewStructure.setContentDescription(CharSequence)).
Visual properties such as visibility (ViewStructure.setVisibility(int)), dimensions (ViewStructure.setDimens(int, int, int, int, int, int)), and opacity (ViewStructure.setOpaque(boolean)).
For views representing text fields, text properties such as the text itself (ViewStructure.setText(CharSequence)), text hints (ViewStructure.setHint(CharSequence), input type (ViewStructure.setInputType(int)),
For views representing HTML nodes, its web domain (ViewStructure.setWebDomain(String)) and HTML properties ((ViewStructure.setHtmlInfo(android.view.ViewStructure.HtmlInfo)).

The default implementation of this method already sets most of these properties based on related View methods (for example, the autofill id is set using getAutofillId(), the autofill type set using getAutofillType(), etc.), and views in the standard Android widgets library also override it to set their relevant properties (for example, TextView already sets the text properties), so it's recommended to only override this method (and call super.onProvideAutofillStructure()) when:

The view contents does not include PII (Personally Identifiable Information), so it can call ViewStructure.setDataIsSensitive(boolean) passing false.
The view can only be autofilled with predefined options, so it can call ViewStructure.setAutofillOptions(CharSequence[]).

Note: The left and top values set in ViewStructure.setDimens(int, int, int, int, int, int) must be relative to the next ViewGroup.isImportantForAutofill() predecessor view included in the structure.

Views support the Autofill Framework mainly by:

Providing the metadata defining what the view means and how it can be autofilled.
Notifying the Android System when the view value changed by calling AutofillManager.notifyValueChanged(View).
Implementing the methods that autofill the view.

This method is responsible for the former; autofill(android.view.autofill.AutofillValue) is responsible for the latter.

It also sets the autofill options in the structure; when overridden, it should set it as well, either explicitly by calling ViewStructure.setAutofillOptions(CharSequence[]) or implicitly by calling super.onProvideAutofillStructure(structure, flags).

Parameters
`structure`	`ViewStructure`: fill in with structured view data for autofill purposes.
`flags`	`int`: optional flags. Value is either `0` or `View.AUTOFILL_FLAG_INCLUDE_NOT_IMPORTANT_VIEWS`

performItemClick

Added in API level 1

public boolean performItemClick (View view, 
                int position, 
                long id)

Call the OnItemClickListener, if it is defined. Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc.

Parameters
`view`	`View`: The view within the AdapterView that was clicked.
`position`	`int`: The position of the view in the adapter.
`id`	`long`: The row id of the item that was clicked.

Returns
`boolean`	True if there was an assigned OnItemClickListener that was called, false otherwise is returned.

removeAllViews

Added in API level 1

public void removeAllViews ()

This method is not supported and throws an UnsupportedOperationException when called.

Throws
`UnsupportedOperationException`	Every time this method is invoked.

removeView

Added in API level 1

public void removeView (View child)

This method is not supported and throws an UnsupportedOperationException when called.

Parameters
`child`	`View`: Ignored.

Throws
`UnsupportedOperationException`	Every time this method is invoked.

removeViewAt

Added in API level 1

public void removeViewAt (int index)

This method is not supported and throws an UnsupportedOperationException when called.

Parameters
`index`	`int`: Ignored.

Throws
`UnsupportedOperationException`	Every time this method is invoked.

setAdapter

Added in API level 1

public abstract void setAdapter (T adapter)

Sets the adapter that provides the data and the views to represent the data in this widget.

Parameters
`adapter`	`T`: The adapter to use to create this view's content.

setEmptyView

Added in API level 1

public void setEmptyView (View emptyView)

Sets the view to show if the adapter is empty

Parameters
`emptyView`	`View`

setFocusable

Added in API level 26

public void setFocusable (int focusable)

Sets whether this view can receive focus.

Setting this to FOCUSABLE_AUTO tells the framework to determine focusability automatically based on the view's interactivity. This is the default.

Setting this to NOT_FOCUSABLE will ensure that this view is also not focusable in touch mode.

Parameters
`focusable`	`int`: Value is `View.NOT_FOCUSABLE`, `View.FOCUSABLE`, or `View.FOCUSABLE_AUTO`

setFocusableInTouchMode

Added in API level 1

public void setFocusableInTouchMode (boolean focusable)

Set whether this view can receive focus while in touch mode. Setting this to true will also ensure that this view is focusable.

Parameters
`focusable`	`boolean`: If true, this view can receive the focus while in touch mode.

setOnClickListener

Added in API level 1

public void setOnClickListener (View.OnClickListener l)

Parameters
`l`	`View.OnClickListener`: The callback that will run This value may be `null`.

Added in API level 1

public void setOnItemClickListener (AdapterView.OnItemClickListener listener)

Parameters
`listener`	`AdapterView.OnItemClickListener`: The callback that will be invoked. This value may be `null`.

Added in API level 1

public void setOnItemLongClickListener (AdapterView.OnItemLongClickListener listener)

Parameters
`listener`	`AdapterView.OnItemLongClickListener`: The callback that will run

Added in API level 1

public void setOnItemSelectedListener (AdapterView.OnItemSelectedListener listener)

Parameters
`listener`	`AdapterView.OnItemSelectedListener`: The callback that will run This value may be `null`.

setSelection

Added in API level 1

public abstract void setSelection (int position)

Sets the currently selected item. To support accessibility subclasses that override this method must invoke the overridden super method first.

Parameters
`position`	`int`: Index (starting at 0) of the data item to be selected.

Protected methods

canAnimate

Added in API level 1

protected boolean canAnimate ()

Indicates whether the view group has the ability to animate its children after the first layout.

Returns
`boolean`	true if the children can be animated, false otherwise

dispatchRestoreInstanceState

Added in API level 1

protected void dispatchRestoreInstanceState (SparseArray<Parcelable> container)

Override to prevent thawing of any views created by the adapter.

Parameters
`container`	`SparseArray`: The SparseArray which holds previously saved state.

dispatchSaveInstanceState

Added in API level 1

protected void dispatchSaveInstanceState (SparseArray<Parcelable> container)

Override to prevent freezing of any views created by the adapter.

Parameters
`container`	`SparseArray`: The SparseArray in which to save the view's state.

onDetachedFromWindow

Added in API level 1

protected void onDetachedFromWindow ()

This is called when the view is detached from a window. At this point it no longer has a surface for drawing.
If you override this method you must call through to the superclass implementation.

onLayout

Added in API level 1

protected void onLayout (boolean changed, 
                int left, 
                int top, 
                int right, 
                int bottom)

Called from layout when this view should assign a size and position to each of its children. Derived classes with children should override this method and call layout on each of their children.

Parameters
`changed`	`boolean`: This is a new size or position for this view
`left`	`int`: Left position, relative to parent
`top`	`int`: Top position, relative to parent
`right`	`int`: Right position, relative to parent
`bottom`	`int`: Bottom position, relative to parent
