Android自定义键盘布局切换

Question

我想开发自己的键盘。我按照here

中的解释进行操作

当我仅使用一种键盘布局时，这就像一种魅力。如果我要使用两种布局并在它们之间切换，则布局会发生奇怪的情况。

letter keyboard pic1中的一切都很好，现在我切换到符号键盘布局。 symbols keyboard 但是在这里我们可以看到右键按钮从右侧边框退出。 现在，将键盘布局切换回字母键盘，看看 右列完全消失。 letters keyboard 2 如何解决此问题？

键盘布局看起来像这样

我这样切换键盘布局

        case 0:
            if (iKeyboardType == 1) {
                keyboard = new Keyboard(this, R.xml.symbols_layout);
                iKeyboardType = 2;
            }
            else if (iKeyboardType == 2){
                keyboard = new Keyboard(this, R.xml.keys_layout);
                iKeyboardType = 1;
            }
            keyboardView.setKeyboard(keyboard);
            keyboardView.invalidateAllKeys();
            break;

Answer 1

我找不到任何正确的解决方案，所以我用自己的方式做到了。如果两个布局中的键大小相同，则一切正常，并且键不会移到外面。也许对某人有帮助。

Answer 2

遇到类似问题，但不确定是否相同。我所做的是确保行中每个按钮的android keywidth不超过100%p：

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
    android:keyWidth="10%p"
    android:horizontalGap="0dp"
