ReplacementTransformationMethod

Kotlin |Java

public abstract class ReplacementTransformationMethod
extends Object implements TransformationMethod

java.lang.Object
↳	android.text.method.ReplacementTransformationMethod

Known direct subclasses

HideReturnsTransformationMethod, SingleLineTransformationMethod

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.

`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.

From interface


        
          android.text.method.TransformationMethod

`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.
