当用户按下键盘上的按钮时在字母键盘和数字键盘之间切换

Question

我正在构建自定义 Hindi android soft keyboard 来自 this tutorial.I 在这个 [=16= 上有一个名为 123 的 key ].我想将键盘布局更改为另一种由数字组成的布局（我已经为这个数字布局准备了 xml 文件）但我不知道。我应该怎么做？这是我的 xml 印地文字母文件：

</PreferenceScreen>

这是主要的 java 文件：

public class SimpleIME extends InputMethodService implements KeyboardView.OnKeyboardActionListener {


    private KeyboardView kv;
    private Keyboard keyboard;

    private boolean caps = false;

    @Override
    public View onCreateInputView()
    {
        kv = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard, null);
        keyboard = new Keyboard(this, R.xml.qwerty);
        kv.setKeyboard(keyboard);
        kv.setOnKeyboardActionListener(this);
        return kv;
    }

    private void playClick(int keyCode)
    {
        AudioManager am = (AudioManager)getSystemService(AUDIO_SERVICE);
        switch(keyCode)
        {
            case 32:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_SPACEBAR);
                break;
            case Keyboard.KEYCODE_DONE:
            case 10:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_RETURN);
                break;
            case Keyboard.KEYCODE_DELETE:
                am.playSoundEffect(AudioManager.FX_KEYPRESS_DELETE);
                break;
            default: am.playSoundEffect(AudioManager.FX_KEYPRESS_STANDARD);
        }
    }


    @Override
    public void onKey(int primaryCode, int[] keyCodes)
    {
        InputConnection ic = getCurrentInputConnection();
        playClick(primaryCode);
        switch(primaryCode)
        {
            case Keyboard.KEYCODE_DELETE :
                ic.deleteSurroundingText(1, 0);
                break;
            case Keyboard.KEYCODE_SHIFT:
                caps = !caps;
                keyboard.setShifted(caps);
                kv.invalidateAllKeys();
                break;
            case Keyboard.KEYCODE_DONE:
                ic.sendKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
                break;
            default:
                char code = (char)primaryCode;
//                Toast.makeText(getApplicationContext(),String.valueOf(code),Toast.LENGTH_SHORT).show();
                ic.commitText(String.valueOf(code),1);
        }
    }

    @Override
    public void onPress(int primaryCode) {
    }

    @Override
    public void onRelease(int primaryCode) {
    }

    @Override
    public void onText(CharSequence text) {
    }

    @Override
    public void swipeDown() {
    }

    @Override
    public void swipeLeft() {
    }

    @Override
    public void swipeRight() {
    }

    @Override
    public void swipeUp() {
    }
}

Answer 1

在 Onkey 方法的 switch 语句中将 case 设为 case 0（123 键的代码）并使用以下内容：

keyboard = new Keyboard(this, R.xml.number);
kv.setKeyboard(keyboard);
kv.setOnKeyboardActionListener(this);

这里 number.xml 是数字的布局文件 keyboard.Hope 这很有帮助。
