PasswordEntryKeyboard

public class PasswordEntryKeyboard extends android.inputmethodservice.Keyboard
A basic, embed-able keyboard designed for password entry. Allows entry of all Latin-1 characters. It has two modes: alpha and numeric. In alpha mode, it allows all Latin-1 characters and enables an additional keyboard with symbols. In numeric mode, it shows a 12-key DTMF dialer-like keypad with alpha characters hints.

voidenableShiftLock()
Allows shiftlock to be turned on. See {@link #setShiftLocked(boolean)}

                R.dimen.password_keyboard_spacebar_vertical_correction);
public booleanisShifted()
Whether or not keyboard is shifted.

return
true if keyboard state is shifted.

voidsetEnterKeyResources(android.content.res.Resources res, int previewId, int iconId, int labelId)
Allows enter key resources to be overridden

param
res resources to grab given items from
param
previewId preview drawable shown on enter key
param
iconId normal drawable shown on enter key
param
labelId string shown on enter key

        if (mEnterKey != null) {

            }
        }
voidsetShiftLocked(boolean shiftLocked)
Turn on shift lock. This turns on the LED for this key, if it has one. It should be followed by a call to {@link KeyboardView#invalidateKey(int)} or {@link KeyboardView#invalidateAllKeys()}

param
shiftLocked

public booleansetShifted(boolean shiftState)
Turn on shift mode. Sets shift mode and turns on icon for shift key. It should be followed by a call to {@link KeyboardView#invalidateKey(int)} or {@link KeyboardView#invalidateAllKeys()}

param
shiftLocked
