Class Overview

ActionLabel is a specialized text display widget. An upper and lower bound for text size and a maximum number of lines are provided and the layout is adjusted automatically to find the largest possible text size satisfying those constraints.

In order to provide a fixed bound, an ActionLabel should always be used with a width and height of "match_parent" or a specific size. When created programmatically, you must supply a LayoutParams to do this: 

 LayoutParams lp = new ViewGroup.LayoutParams(200, 50);
 parent.addView(label, lp);

Supported attributes are:

  • text
  • textColor
  • maxLines
  • minTextSize
  • maxTextSize
  • lineSpacingExtra
  • lineSpacingMultiplier
  • fontFamily
  • typeface
  • textStyle
  • gravity

public final int getCurrentTextColor ()

Return the current color selected for normal text.

Returns
  • Returns the current text color.

public int getGravity ()

Returns the horizontal and vertical alignment of this ActionLabel.

public float getLineSpacingExtra ()

Gets the line spacing extra space

Returns
  • the extra space that is added to the height of each lines of this TextView.
See Also

public float getLineSpacingMultiplier ()

Gets the line spacing multiplier

Returns
  • the value by which each line's height is multiplied to get its actual height.
See Also

public int getMaxLines ()

public final ColorStateList getTextColors ()

Gets the text colors for the different states (normal, selected, focused) of the TextView.

See Also

public Typeface getTypeface ()

Returns
  • the current typeface and style in which the text is being displayed.
See Also

public void onRtlPropertiesChanged (int layoutDirection)

public void setGravity (int gravity)

Sets the horizontal alignment of the text and the vertical gravity that will be used when there is extra space in the ActionLabel beyond what is required for the text itself.

See Also

public void setLineSpacing (float add, float mult)

Sets line spacing for this TextView. Each line will have its height multiplied by mult and have add added to it.

public void setMaxLines (int lines)

Limits the ActionLabel to no more than this many lines tall.

public void setMaxTextSize (float size)

Limits the text size to no larger than this value. Text will try to be this size if possible, then be reduced in size until it fits available space.

public void setMaxTextSize (int unit, float size)

Limits the text size to no larger than this value. Text will try to be this size if possible, then be reduced in size until it fits available space.

public void setMinTextSize (float size)

Limits the text size to no smaller than this value. Text size is decreased until the content can be rendered within the available space.

Parameters
size interpreted as "scaled pixel" units

public void setMinTextSize (int unit, float size)

Limits the text size to no smaller than this value. Text size is decreased until the content can be rendered within the available space.

public void setText (CharSequence text)

Sets the text to be displayed by this label.

public void setTextColor (ColorStateList colors)

Sets the text color.

See Also

public void setTextColor (int color)

Sets the text color for all the states (normal, selected, focused) to be this color.

public void setTypeface (Typeface tf)

Sets the typeface and style in which the text should be displayed. Note that not all Typeface families actually have bold and italic variants, so you may need to use setTypeface(Typeface, int) to get the appearance that you actually want.
