SearchView

Kotlin |Java

public class SearchView
extends LinearLayout implements CollapsibleActionView

java.lang.Object
↳	android.view.View
	↳	android.view.ViewGroup
		↳	android.widget.LinearLayout
			↳	android.widget.SearchView

A widget that provides a user interface for the user to enter a search query and submit a request to a search provider. Shows a list of query suggestions or results, if available, and allows the user to pick a suggestion or result to launch into.

When the SearchView is used in an ActionBar as an action view for a collapsible menu item, it needs to be set to iconified by default using setIconifiedByDefault(true). This is the default, so nothing needs to be done.

If you want the search field to always be visible, then call setIconifiedByDefault(false).

`int`	`CLIP_TO_PADDING_MASK` We clip to padding when FLAG_CLIP_TO_PADDING and FLAG_PADDING_NOT_NULL are set at the same time.
`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. 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.
