我正在开发的应用程序的一个功能是人们可以互相聊天。在ChatFragment中。我想拥有与Whatsapp和Telegram相同的功能，您可以单击emoticon按钮和键盘切换到Emojipicker 没有任何过渡，其中emoticonpicker具有与我的键盘相同的布局高度(就像Whatsapp和Telegram)。
当我实现它并从软件键盘切换到表情符号键盘时，我的软件键盘将消失，我的表情符号选择器的可见性将从GONE设置为VISIBLE。除了由于布局的改变而导致的难看的错误转换之外，它在所有设备上的尺寸都是一样的，而没有考虑到键盘的高度不同。我正在使用以下表情器https://github.com/rockerhieu/emojicon
有人知道如何改变我的实现，以使我的表情符号选择器是相同的高度作为我的键盘?我尝试了各种各样的方法，但都不起作用。下面是我的chatfragment和layout的一些代码。

在ChatFragment中，我将SoftInputMode设置为SOFT_INPUT_ADJUST_NOTHING，因为我试图加载我的软件键盘后面的表情符号键盘，它工作得非常非常好。唯一的问题是表情符号的高度。当我在我的Galaxy s3上测试时，它的大小和键盘一样，在我的nexus 5和Galaxy Y DUO上，它的布局比键盘布局大一点，小一点，所以看不见的表情符号选择器伸出了软件键盘…
有没有人有任何提示，我如何才能成功地实现这一点，而不得到奇怪的布局故障或动画?
