Returns
`int[]`	the current auto-size `int` sizes array (in pixels).

getAutoSizeTextType

added in version 26.1.0

int getAutoSizeTextType (TextView textView)

Returns the type of auto-size set for this widget.

Parameters
`textView`	`TextView`

Returns
`int`	an `int` corresponding to one of the auto-size types: `AUTO_SIZE_TEXT_TYPE_NONE` or `AUTO_SIZE_TEXT_TYPE_UNIFORM`

getCompoundDrawablesRelative

added in version 25.1.0

Drawable[] getCompoundDrawablesRelative (TextView textView)

Returns drawables for the start, top, end, and bottom borders from the given text view.

Parameters
`textView`	`TextView`

Returns
`Drawable[]`

getMaxLines

added in version 24.1.0

int getMaxLines (TextView textView)

Returns the maximum number of lines displayed in the given TextView, or -1 if the maximum height was set in pixels instead.

Parameters
`textView`	`TextView`

Returns
`int`

getMinLines

added in version 24.1.0

int getMinLines (TextView textView)

Returns the minimum number of lines displayed in the given TextView, or -1 if the minimum height was set in pixels instead.

Parameters
`textView`	`TextView`

Returns
`int`

setAutoSizeTextTypeUniformWithConfiguration

added in version 26.1.0

void setAutoSizeTextTypeUniformWithConfiguration (TextView textView, 
                int autoSizeMinTextSize, 
                int autoSizeMaxTextSize, 
                int autoSizeStepGranularity, 
                int unit)

Specify whether this widget should automatically scale the text to try to perfectly fit within the layout bounds. If all the configuration params are valid the type of auto-size is set to AUTO_SIZE_TEXT_TYPE_UNIFORM.

Parameters
`textView`	`TextView`
`autoSizeMinTextSize`	`int`: the minimum text size available for auto-size
`autoSizeMaxTextSize`	`int`: the maximum text size available for auto-size
`autoSizeStepGranularity`	`int`: the auto-size step granularity. It is used in conjunction with the minimum and maximum text size in order to build the set of text sizes the system uses to choose from when auto-sizing
`unit`	`int`: the desired dimension unit for all sizes above. See `TypedValue` for the possible dimension units

Throws
`IllegalArgumentException`	if any of the configuration params are invalid.

setAutoSizeTextTypeUniformWithPresetSizes
