DateTimeKeyListener

Kotlin |Java

public class DateTimeKeyListener
extends NumberKeyListener

java.lang.Object
↳	android.text.method.MetaKeyKeyListener
	↳	android.text.method.BaseKeyListener
		↳	android.text.method.NumberKeyListener
			↳	android.text.method.DateTimeKeyListener

For entering dates and times in the same text field.

As for all implementations of KeyListener, this class is only concerned with hardware keyboards. Software input methods have no obligation to trigger the methods in this class.

From class


        
          android.text.method.NumberKeyListener

`CharSequence`	`filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend)` This method is called when the buffer is going to replace the range `dstart … dend` of `dest` with the new text from the range `start … end` of `source`.
`abstract char[]`	`getAcceptedChars()` You can say which characters you can accept.
`int`	`lookup(KeyEvent event, Spannable content)`
`static boolean`	`ok(char[] accept, char c)`

From class


        
          android.text.method.BaseKeyListener

`boolean`	`backspace(View view, Editable content, int keyCode, KeyEvent event)` Performs the action that happens when you press the `KeyEvent#KEYCODE_DEL` key in a `TextView`.

`boolean`	`onKeyDown(View view, Editable content, int keyCode, KeyEvent event)` Handles presses of the meta keys.
`boolean`	`onKeyOther(View view, Editable content, KeyEvent event)` Base implementation handles ACTION_MULTIPLE KEYCODE_UNKNOWN by inserting the event's text into the content.

From class


        
          android.text.method.MetaKeyKeyListener

`static void`	`adjustMetaAfterKeypress(Spannable content)` Call this method after you handle a keypress so that the meta state will be reset to unshifted (if it is not still down) or primed to be reset to unshifted (once it is released).

`static void`	`clearMetaKeyState(Editable content, int states)`
`long`	`clearMetaKeyState(long state, int which)` Clears the state of the specified meta key if it is locked.
`void`	`clearMetaKeyState(View view, Editable content, int states)`
`static final int`	`getMetaState(CharSequence text)` Gets the state of the meta keys.
`static final int`	`getMetaState(CharSequence text, int meta)` Gets the state of a particular meta key.
`static final int`	`getMetaState(long state)` Gets the state of the meta keys.
`static final int`	`getMetaState(CharSequence text, KeyEvent event)` Gets the state of the meta keys for a specific key event.
`static final int`	`getMetaState(long state, int meta)` Gets the state of a particular meta key.
`static final int`	`getMetaState(CharSequence text, int meta, KeyEvent event)` Gets the state of a particular meta key to use with a particular key event.
`static long`	`handleKeyDown(long state, int keyCode, KeyEvent event)` Handles presses of the meta keys.
`static long`	`handleKeyUp(long state, int keyCode, KeyEvent event)` Handles release of the meta keys.
`static boolean`	`isMetaTracker(CharSequence text, Object what)` Returns true if this object is one that this class would use to keep track of any meta state in the specified text.
`static boolean`	`isSelectingMetaTracker(CharSequence text, Object what)` Returns true if this object is one that this class would use to keep track of the selecting meta state in the specified text.
`boolean`	`onKeyDown(View view, Editable content, int keyCode, KeyEvent event)` Handles presses of the meta keys.
`boolean`	`onKeyUp(View view, Editable content, int keyCode, KeyEvent event)` Handles release of the meta keys.
`static long`	`resetLockedMeta(long state)` Call this if you are a method that ignores the locked meta state (arrow keys, for example) and you handle a key.
`static void`	`resetLockedMeta(Spannable content)` Call this if you are a method that ignores the locked meta state (arrow keys, for example) and you handle a key.
`static void`	`resetMetaState(Spannable text)` Resets all meta state to inactive.

From class


        
          java.lang.Object

Fields

CHARACTERS

Added in API level 1
Deprecated in API level 26

public static final char[] CHARACTERS

This field was deprecated in API level 26.
Use getAcceptedChars() instead.

This field used to list the characters that were used. But is now a fixed data field that is the list of code units used for the deprecated case where the class is instantiated with null or no input parameter.
