Чтобы отключить триггер управления редактированием LWUIT, вы можете использовать следующий код.
textArea.setNativeTextboxTrigger(false);
Вам необходимо реализовать следующий код в исходном коде LWUIT TextArea
static final String CLIENT_PROPERTY_FIRE_ACTION_TIMES = "FIRE-ACTION-TIMES";
static final String CLIENT_PROPERTY_DEAFULT_TEXT = "DEFAULT-TEXT";
public void setNativeTextboxTrigger(boolean enable) {
registerNativeTextboxTriggerEvent = enable;
static final String CLIENT_PROPERTY_FIRE_ACTION_TIMES = "FIRE-ACTION-TIMES";
static final String CLIENT_PROPERTY_DEAFULT_TEXT = "DEFAULT-TEXT";
try {
if( registerNativeTextboxTriggerEvent ) {
String text = null != ( text = getText() ) ? text : "";
this.putClientProperty(CLIENT_PROPERTY_DEAFULT_TEXT, text);
this.putClientProperty(CLIENT_PROPERTY_FIRE_ACTION_TIMES, String.valueOf(0));
final UIManager m = UIManager.getInstance();
setNativeCommandsText(m.localize("ok", "OK"), m.localize("cancel", "Cancel"));
this.addActionListener(nativeTriggerListener = getNativeTriggerActionListener());
} else {
this.putClientProperty(CLIENT_PROPERTY_DEAFULT_TEXT, null);
this.putClientProperty(CLIENT_PROPERTY_FIRE_ACTION_TIMES, null);
setNativeCommandsText(null, null);
if( null != nativeTriggerListener ) {
this.removeActionListener(nativeTriggerListener);
nativeTriggerListener = null;
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
ActionListener getNativeTriggerActionListener() {
return new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if( evt.getSource() instanceof TextArea ) {
final TextArea tar = (TextArea)evt.getSource();
final String textEntered = tar.getText().trim();
final String defaultText = (String)tar.getClientProperty(CLIENT_PROPERTY_DEAFULT_TEXT);
int fireActionTimes = Integer.parseInt((String)tar.getClientProperty(CLIENT_PROPERTY_FIRE_ACTION_TIMES));
++fireActionTimes;
int value = fireActionTimes % 2;
if( 0 == value ) {
fireActionTimes = 0;
if( textEntered.equals("") || textEntered.toUpperCase().equals(defaultText.toUpperCase())) {

}

} else

}
