Question

我正在构建基于https://github.com/android/platform_development/tree/master/samples/SoftKeyboard

的Android自定义键盘

他们在res / xml文件夹下有qwerty和symbols键盘。我添加了一个虚拟键盘（friendlist.xml），如下所示：

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
        android:keyWidth="20%p"
        android:horizontalGap="0px"
        android:verticalGap="0px"
        android:keyHeight="20%p"
        >

</Keyboard>

我需要以编程方式将“Key”添加到此键盘（friendlist.xml）中。在SoftKeyboard.java中，

我添加了以下内容：

private LatinKeyboard mFriendlistKeyboard;

    @Override public void onInitializeInterface() {
        if (mQwertyKeyboard != null) {
            // Configuration changes can happen after the keyboard gets recreated,
            // so we need to be able to re-build the keyboards if the available
            // space has changed.
            int displayWidth = getMaxWidth();
            if (displayWidth == mLastDisplayWidth) return;
            mLastDisplayWidth = displayWidth;
        }
        mQwertyKeyboard = new LatinKeyboard(this, R.xml.qwerty);
        mSymbolsKeyboard = new LatinKeyboard(this, R.xml.symbols);
        mSymbolsShiftedKeyboard = new LatinKeyboard(this, R.xml.symbols_shift);
        mFriendlistKeyboard = new LatinKeyboard(this, R.xml.friendlist);

    }

但我找不到任何可以在运行时将Row和Key添加到键盘中的函数。

请欣赏任何帮助。谢谢！

Cheerio， Mark Thien

还有一个额外的构造函数，它作为参数键添加到键盘。它仅限于字符。

Keyboard Constructor source

 public Keyboard(Context context, int layoutTemplateResId, 
        CharSequence characters, int columns, int horizontalPadding);

仅包含人声的动态键盘示例：

mFriendlistKeyboard = new Keyboard(this, R.xml.friendlist, 'AEIOU', -1, 0);

如果您需要的不仅仅是“字符”键，那么扩展键盘将是必要的。
