我想在用户编辑virtual keyboard
时显示textfield
。我采用这种方法:
public class ChpModif extends TextField {
public ChpModif(int maxChars, FocusListener focusListener, DataChangedListener dataChangeListener, VirtualKeyboard vkb)
{
super();
setReplaceMenu(false);
if (maxChars != -1)
setMaxSize(maxChars);
addFocusListener(focusListener);
addDataChangeListener(dataChangeListener);
if (vkb != null)
VirtualKeyboard.bindVirtualKeyboard(this, vkb);
}
protected Command installCommands(Command clear, Command t9)
{
return null;
}
}
public class ModifierFicheClient extends Ecran implements ActionListener, DataChangedListener, FocusListener
{
private VirtualKeyboard vkNombre = new VirtualKeyboard();
private String textFieldStatus, listBoxStatus;
private ListBox genretxt;
private boolean modifFromUpdate;
private ChpModif nomtxt,prenomtxt,cintxt,adressetxt/*,genretxt*/,lieutxt,professiontxt,courieltxt,teltxt,datenaisstxt;
private Component cursorItem;
...
public ModifierFicheClient(SmartPhoneBanking controller,String prosp_id,int recordStoreID,Form prevForm)
{
super("");
vkNombre.setInputModeOrder(new String[]{VirtualKeyboard.NUMBERS_SYMBOLS_MODE});
...
modifFromUpdate = false;
cintxt = new ChpModif(12, this, this, vkNombre);
...
}
public void dataChanged(int type, int index) {
textFieldStatus = "CHANGED";
if (!modifFromUpdate)
{
try
{
if (type == DataChangedListener.ADDED || type == DataChangedListener.CHANGED || type == DataChangedListener.REMOVED)
{
if (Display.getInstance().isVirtualKeyboardShowingSupported())
{
if (!Display.getInstance().isVirtualKeyboardShowing())
cursorItem.pointerReleased(cursorItem.getAbsoluteX(), cursorItem.getAbsoluteY());
}
}
}
catch (ClassCastException cce)
{}
}
}
public void focusGained(Component chp) {
cursorItem = chp;
}
public void focusLost(Component arg0) {
}
protected void onShowCompleted()
{
...
update();
}
public void update()
{
modifFromUpdate = true;
cintxt.setText(fichesignalitique.elementAt(0).toString());
...
modifFromUpdate = false;
}
...
}
问题在于,当我第一次编辑textfield
时,会显示virtualkeyboard
;然后,我点击Ok
的{{1}}按钮,然后再次编辑virtualkeyboard
。但是在这个时候textfield
没有显示!
那么每次编辑virtualkeyboard
时如何显示virtualkeyboard
?
答案 0 :(得分:1)
完全有可能这是一个在1.5中修复的1.4错误,因为我现在看不到它。 VKB在1.4中是全新的。
