You can use ChipDrawable directly in contexts that require a Drawable. For example, an * auto-complete enabled EditText can replace snippets of text with a ChipDrawable to represent it * as a semantic entity. To create an instance of ChipDrawable, use {@link * ChipDrawable#createFromResource(Context, int)} and pass in an XML resource in this form: * *
{@code
*
*
* The basic attributes you can set are: * *
When used in this stand-alone mode, the host view must explicitly manage the ChipDrawable's * state: * *
ChipDrawable's horizontal layout is as follows: * *
* chipStartPadding iconEndPadding closeIconStartPadding chipEndPadding * + + + + * | | | | * | iconStartPadding | textStartPadding textEndPadding | closeIconEndPadding | * | + | + + | + | * | | | | | | | | * v v v v v v v v * +-----+----+-----------+----+----+---------------------+----+----+----------+----+-----+ * | | | XX | | | XX X X X XXX | | | X X | | | * | | | XX | | | X X X X X X X | | | XX XX | | | * | | | XX XX | | | X XXXX X XXX | | | XX | | | * | | | XXX | | | X X X X X X | | | XX XX | | | * | | | X | | | XX X X X X | | | X X | | | * +-----+----+-----------+----+----+---------------------+----+----+----------+----+-----+ * ^ ^ ^ * | | | * + + + * chipIconSize *dynamic* closeIconSize ** *
ChipDrawable contains three child drawables: {@code chipIcon}, {@code checkedIcon}, and {@code * closeIcon}. chipIcon and checkedIcon inherit the state of this drawable, but closeIcon contains * its own state that you can set with {@link #setCloseIconState(int[])}. * *
For more information, see the component
* developer guidance and design
* guidelines.
