ReplacementTransformationMethod


public abstract class ReplacementTransformationMethod
extends Object implements TransformationMethod

java.lang.Object
   ↳ android.text.method.ReplacementTransformationMethod
HideReturnsTransformationMethod This transformation method causes any carriage return characters (\r) to be hidden by displaying them as zero-width non-breaking space characters (\ufeff). 
SingleLineTransformationMethod This transformation method causes any newline characters (\n) to be displayed as spaces instead of causing line breaks, and causes carriage return characters (\r) to have no appearance. 


This transformation method causes the characters in the getOriginal() array to be replaced by the corresponding characters in the getReplacement() array.

Summary

Public constructors

ReplacementTransformationMethod()

Public methods

CharSequence getTransformation(CharSequence source, View v)

Returns a CharSequence that will mirror the contents of the source CharSequence but with the characters in getOriginal() replaced by ones from getReplacement().

void onFocusChanged(View view, CharSequence sourceText, boolean focused, int direction, Rect previouslyFocusedRect)

This method is called when the TextView that uses this TransformationMethod gains or loses focus.

Protected methods

abstract char[] getOriginal()

Returns the list of characters that are to be replaced by other characters when displayed.

abstract char[] getReplacement()

Returns a parallel array of replacement characters for the ones that are to be replaced.

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

abstract CharSequence getTransformation(CharSequence source, 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.

abstract void onFocusChanged(View view, CharSequence sourceText, boolean focused, int direction, Rect previouslyFocusedRect)

This method is called when the TextView that uses this TransformationMethod gains or loses focus.
