| ↳ | android.text.TextDirectionHeuristics |
Some objects that implement TextDirectionHeuristic. Use these with
the unicodeWrap() methods in BidiFormatter.
Also notice that these direction heuristics correspond to the same types of constants
provided in the View class for setTextDirection(), such as TEXT_DIRECTION_RTL.
To support versions lower than JELLY_BEAN_MR2,
you can use the support library's TextDirectionHeuristicsCompat
class.

If the text contains any strong right to left non-format character, determines that the direction is right to left, falling back to left to right if it finds none.
Determines the direction based on the first strong directional character, including bidi format chars, falling back to left to right if it finds none. This is the default behavior of the Unicode Bidirectional Algorithm.
Determines the direction based on the first strong directional character, including bidi format chars, falling back to right to left if it finds none. This is similar to the default behavior of the Unicode Bidirectional Algorithm, just with different fallback behavior.
Force the paragraph direction to the Locale direction. Falls back to left to right.
Always decides that the direction is left to right.
Always decides that the direction is right to left.
