Method Details

setTintList

public void setTintList(@Nullable
 ColorStateList tint)

Description copied from class: Drawable

Specifies tint color for this drawable as a color state list.

A Drawable's drawing content will be blended together with its tint before it is drawn to the screen.

Note: Setting a color filter via Drawable.setColorFilter(ColorFilter) overrides tint.

Overrides:

setTintList in class Drawable

Parameters:

tint - Color state list to use for tinting this drawable, or null to clear the tint

See Also:

• Drawable.setTint(int)
• Drawable.setTintBlendMode(BlendMode)

onStateChange

protected boolean onStateChange(@NonNull
 int[] stateSet)

Description copied from class: Drawable

Override this in your subclass to change appearance if you recognize the specified state.

Overrides:

onStateChange in class Drawable

Returns:

Returns true if the state change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last state.

isStateful

public boolean isStateful()

Description copied from class: Drawable

Indicates whether this drawable will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

Overrides:

isStateful in class Drawable

Returns:

True if this drawable changes its appearance based on state, false otherwise.

See Also:

• Drawable.setState(int[])

hasFocusStateSpecified

public boolean hasFocusStateSpecified()

Description copied from class: Drawable

Indicates whether this drawable has at least one state spec explicitly specifying state_focused.

Note: A View uses a Drawable instance as its background and it changes its appearance based on a state. On keyboard devices, it should specify its state_focused to make sure the user knows which view is holding the focus.

Overrides:

hasFocusStateSpecified in class Drawable

Returns:

true if state_focused is specified for this drawable.

setAlpha

public void setAlpha(int alpha)

Description copied from class: Drawable

Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

Overrides:

setAlpha in class Drawable

getAlpha

public int getAlpha()

Description copied from class: Drawable

Gets the current alpha value for the drawable. 0 means fully transparent, 255 means fully opaque. This method is implemented by Drawable subclasses and the value returned is specific to how that class treats alpha. The default return value is 255 if the class does not override this method to return a value specific to its use of alpha.

Overrides:

getAlpha in class Drawable
