SoftKeyboard，invalidateAllKeys（）似乎什么都不做

Question

我有一个带有KeyboardView的应用程序，其中包含一个qwerty键盘。在它的字母中我有一个大写键。

在我的java中，我有切换来检查按下了哪个键，在其中一个案例中我有这个：

//...
case -5:
 caps = !caps;
 keyboard.setShifted(caps); //Keyboard
 qwerty_keyboard.invalidateAllKeys(); //KeyboardView
 qwerty_keyboard.requestLayout();
 break;
default:
 char code = (char) primaryCode;
 if (Character.isLetter(code) && caps) {
  code = Character.toUpperCase(code);
 }
 et_search.getText().append(code);
 break;
 //...

默认部分运行良好，并以低或大写形式写入字母。唯一不起作用的是invalidateAllKeys（），它不会将keyboardView中的Keys更改为大写。

我需要做别的吗？

编辑这是我的xml

Answer 1

switch (primaryCode)
    {
        case Keyboard.KEYCODE_DELETE:
            /*ic.deleteSurroundingText(1,0);*/

            CharSequence selectedText = ic.getSelectedText(0);

            if (TextUtils.isEmpty(selectedText)) {
                ic.deleteSurroundingText(1, 0);
            } else {
                ic.commitText("", 1);
            }
            break;

        case Keyboard.KEYCODE_SHIFT:
            isCaps = !isCaps;
            keyboard_one.setShifted(isCaps);
            keyboard_view.invalidateAllKeys();
            break;

        case Keyboard.KEYCODE_DONE:
            ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_ENTER));
            break;

        default:
            char code = (char)primaryCode;
            if(Character.isLetter(code) && isCaps)
                code = Character.toUpperCase(code);
            ic.commitText(String.valueOf(code),1);
    }

}
