TtSearchView

class TtSearchView @JvmOverloads constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int = CoreThemeR.attr.tt_searchview_style) : SearchView

Overview

A SearchView with a search indicator, toggleable collapsed/expanded width, and a lock feature that allows for preventing any user interaction. When the input field shows a query, the search view shows a query icon at the end of the input field. While the search is ongoing, the search view can show a search indicator next to the clear icon.

Features

Searching

The client can updateSearchState of the search view to communicate the current state to the user. See the SearchState for the available states.

Locking

The client can control whether the search view is interactive by setting the ttIsLocked value.

When ttIsLocked is true:

The search view is in the locked state and cannot be interacted with.
The hint is replaced with an explanatory ttLockedReason message.
The search icon is replaced with ttLockedIcon.

Expansion

The client can make the search view expand when it is tapped and collapse when it loses focus by setting ttExpandedWidth.

When ttExpandedWidth is set:

If the collapsed search view has been tapped, it expands its width to the ttExpandedWidth.
If the expanded search view has lost focus, it collapses back to its initial size, as declared in the XML file or according to the value provided by the LayoutParams.

NOTE: If ttExpandedWidth is set, the search view, while collapsed, will not accept any input even if focused and has to be first expanded.

NOTE: If ttExpandedWidth is reset to 0, the search view will resize its width to the value declared in the XML file or according to the value provided by the LayoutParams. If that width is too small for the search view to be usable, the client can updateLayoutParams. It is only valid to updateLayoutParams when ttExpandedWidth is 0, otherwise the collapse or expansion of the search view will override the LayoutParams set by the client.

Theming and customization

For the detailed theming and customization guide refer to the developer portal documentation.

For the reference, below is the stock search view style.

var ttLockedReason: String?

When ttIsLocked is true, this string is shown in the input field explaining why the search view is locked.

Functions

getSearchState

fun getSearchState(): TtSearchView.SearchState

Retrieve the view's SearchState.

onInterceptTouchEvent

open override fun onInterceptTouchEvent(ev: MotionEvent): Boolean

This override is necessary in order to make sure tapping on any part of the SearchView will expand it if it's collapsed. Otherwise, child views would intercept the click and expanding would not work correctly.
