/**
|
|
* A standard toolbar for use within application content.
|
|
*
|
|
* <p>A Toolbar is a generalization of {@link ActionBar action bars} for use
|
|
* within application layouts. While an action bar is traditionally part of an
|
|
* {@link android.app.Activity Activity's} opaque window decor controlled by the framework,
|
|
* a Toolbar may be placed at any arbitrary level of nesting within a view hierarchy.
|
|
* An application may choose to designate a Toolbar as the action bar for an Activity
|
|
* using the {@link android.support.v7.app.AppCompatActivity#setSupportActionBar(Toolbar)
|
|
* setSupportActionBar()} method.</p>
|
|
*
|
|
* <p>Toolbar supports a more focused feature set than ActionBar. From start to end, a toolbar
|
|
* may contain a combination of the following optional elements:
|
|
*
|
|
* <ul>
|
|
* <li><em>A navigation button.</em> This may be an Up arrow, navigation menu toggle, close,
|
|
* collapse, done or another glyph of the app's choosing. This button should always be used
|
|
* to access other navigational destinations within the container of the Toolbar and
|
|
* its signified content or otherwise leave the current context signified by the Toolbar.</li>
|
|
* <li><em>A branded logo image.</em> This may extend to the height of the bar and can be
|
|
* arbitrarily wide.</li>
|
|
* <li><em>A title and subtitle.</em> The title should be a signpost for the Toolbar's current
|
|
* position in the navigation hierarchy and the content contained there. The subtitle,
|
|
* if present should indicate any extended information about the current content.
|
|
* If an app uses a logo image it should strongly consider omitting a title and subtitle.</li>
|
|
* <li><em>One or more custom views.</em> The application may add arbitrary child views
|
|
* to the Toolbar. They will appear at this position within the layout. If a child view's
|
|
* {@link LayoutParams} indicates a {@link Gravity} value of
|
|
* {@link Gravity#CENTER_HORIZONTAL CENTER_HORIZONTAL} the view will attempt to center
|
|
* within the available space remaining in the Toolbar after all other elements have been
|
|
* measured.</li>
|
|
* <li><em>An {@link ActionMenuView action menu}.</em> The menu of actions will pin to the
|
|
* end of the Toolbar offering a few
|
|
* <a href="http://developer.android.com/design/patterns/actionbar.html#ActionButtons">
|
|
* frequent, important or typical</a> actions along with an optional overflow menu for
|
|
* additional actions.</li>
|
|
* </ul>
|
|
* </p>
|
|
*
|
|
* <p>In modern Android UIs developers should lean more on a visually distinct color scheme for
|
|
* toolbars than on their application icon. The use of application icon plus title as a standard
|
|
* layout is discouraged on API 21 devices and newer.</p>
