我正在为 Android 开发一个软键盘，我希望根据 EditText ime 选项将“DONE”键 (KEYCODE_DONE) 更改为“search, next”。我怎样才能做到这一点？

最后我找到了。创建一个扩展键盘的类并添加以下方法并从 InputMethodService 类中调用它。

@Override
protected Key createKeyFromXml(Resources res, Row parent, int x, int y, XmlResourceParser parser) {
    Key key = new Key(res, parent, x, y, parser);
    if (key.codes[0] == -4) {
        mEnterKey = key;
    }
    return key;
}

private Key mEnterKey;
void setImeOptions(Resources res, int options) {
    if (mEnterKey == null) {
        return;
    }

    switch (options & (EditorInfo.IME_MASK_ACTION | EditorInfo.IME_FLAG_NO_ENTER_ACTION)) {
        case EditorInfo.IME_ACTION_GO:
            mEnterKey.iconPreview = null;
            mEnterKey.icon = null;
            mEnterKey.label = "Go";
            break;
        case EditorInfo.IME_ACTION_NEXT:
            mEnterKey.iconPreview = null;
            mEnterKey.icon = null;
            mEnterKey.label = "Next";
            break;
        case EditorInfo.IME_ACTION_SEARCH:
            mEnterKey.icon = null;
            mEnterKey.iconPreview = null;
            mEnterKey.label = "Search";
            break;
        case EditorInfo.IME_ACTION_SEND:
            mEnterKey.iconPreview = null;
            mEnterKey.icon = null;
            mEnterKey.label = "Send";
            break;
        default:
            mEnterKey.icon = null;
            mEnterKey.iconPreview = null;
            mEnterKey.label = "Return";
            break;
    }
}
