TransformationMethodpublic interface TransformationMethod
|TextView uses TransformationMethods to do things like replacing the
characters of passwords with dots, or keeping the newline characters
from causing line breaks in single-line text fields.|
|public java.lang.CharSequence||getTransformation(java.lang.CharSequence source, android.view.View view)|
Returns a CharSequence that is a transformation of the source text --
for example, replacing each character with a dot in a password field.
Beware that the returned text must be exactly the same length as
the source text, and that if the source text is Editable, the returned
text must mirror it dynamically instead of doing a one-time copy.
|public void||onFocusChanged(android.view.View view, java.lang.CharSequence sourceText, boolean focused, int direction, android.graphics.Rect previouslyFocusedRect)|
This method is called when the TextView that uses this
TransformationMethod gains or loses focus.
