我在运行 android 8.1.0 的 Galaxy Tab S4 和运行 android 8.0.0 的手机 Galaxy S8 之间的KeyboardView布局显示有不同的结果。区别在于键宽和水平间隙。

这是我手机上正确的键盘：

在平板电脑上，键盘如下所示：

我们可以看到第一行、第二行和第三行的键具有不同的宽度。但它们的大小必须相同。在平板电脑上，它似乎已调整大小以占用 100% 的父容器。同时，horizo​​ntalGap 将键推出父容器。

下面是定义键盘布局的 XML 代码：

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
    android:keyWidth="8.5%p"
    android:keyHeight="7%p"
    android:keyEdgeFlags="left">

    <Row>
        <Key android:keyLabel="Q" android:keyEdgeFlags="left" />
        <Key android:keyLabel="W" />
        <Key android:keyLabel="E" />
        <Key android:keyLabel="R" />
        <Key android:keyLabel="T" />
        <Key android:keyLabel="Z" />
        <Key android:keyLabel="U" />
        <Key android:keyLabel="I" />
        <Key android:keyLabel="O" />
        <Key android:keyLabel="P" />
        <Key android:codes="55000"  android:keyIcon="@drawable/del_keyboard" android:isRepeatable="true" android:keyWidth="15%p" android:keyEdgeFlags="right" />
    </Row>
    <Row>
        <Key android:keyLabel="　" android:keyHeight="0px" android:keyWidth="0px" android:keyEdgeFlags="left" android:horizontalGap="11.75%p"/>
        <Key android:keyLabel="A"  />
        <Key android:keyLabel="S" />
        <Key android:keyLabel="D" />
        <Key android:keyLabel="F" />
        <Key android:keyLabel="G" />
        <Key android:keyLabel="H" />
        <Key android:keyLabel="J" />
        <Key android:keyLabel="K" />
        <Key android:keyLabel="L" android:keyEdgeFlags="right" />
    </Row>
    <Row>
        <Key android:keyLabel="　" android:keyHeight="0px" android:keyEdgeFlags="left"  android:keyWidth="0px" android:horizontalGap="20%p"/>
        <Key android:keyLabel="Y" />
        <Key android:keyLabel="X" />
        <Key android:keyLabel="C" />
        <Key android:keyLabel="V" />
        <Key android:keyLabel="B" />
        <Key android:keyLabel="N" />
        <Key android:keyLabel="M" android:keyEdgeFlags="right" />
    </Row>
    <Row>
        <Key android:keyLabel="　" android:keyHeight="0px" android:keyWidth="0px" android:horizontalGap="25%p"/>
        <Key android:codes="55001"  android:keyEdgeFlags="left"  android:keyIcon="@drawable/white_space_keyboard" android:keyWidth="50%p" />
    </Row>
</Keyboard>

有关其他信息，keyboardView 位于包含在slidingPaneLayout 中的片段中。有什么想法吗？先感谢您！

我找到了解决方案。获取片段容器的宽度一旦可用。为所有键设置新宽度。使键无效以强制键盘重绘。对于第 2,3 和 4 行的 padding-left，我只是在每行的第一个键之前添加了一些 height = 0 的键。 

//Here we wait for the fragment width to be available
currentView.post(new Runnable() {
        @Override
        public void run() {
            //Set the new width to the keys of the keyboard
            fixKeyboard(mKeyboard, currentView.getWidth());
            //Force redraw the keyboard
            mKeyboardView.invalidateAllKeys();
        }
    });
//...

private void fixKeyboard(Keyboard k, int dw)
{
    List<Keyboard.Key> keys = k.getKeys();

    int key_width = (dw / 11) - 2; //-2 for margin-right
    int row_number = 0;
    int pos_y = 0;
    int key_index_in_row = 0;
    for (Keyboard.Key key : keys)
    {
        if (key.y != pos_y)
        {
            pos_y = key.y;
            row_number++;
            key_index_in_row = 0;
        }

        //Space key
        if(row_number == 3 && key_index_in_row == 3)
        {
            key.width = 5 * key_width;
        }

        //Delete key
        else if(row_number == 0 && key_index_in_row == 10)
        {
            key.width = key_width + 4; //Slightly larger
        }
        else
        {
            key.width = key_width;
        }

        key.gap = 0;

        key.x = key_width * key_index_in_row;
        key_index_in_row++;
    }
}

有了这个 XML

<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="8.5%p"
android:keyHeight="7%p"
