android - 我如何处理 Android 中 Emojipicker 和键盘之间的切换？

Question

我正在开发的应用程序的一个功能是人们可以互相聊天。在聊天 fragment 中。我想拥有与 Whatsapp 和 Telegram 相同的功能，您可以在其中单击表情符号按钮，然后键盘切换到表情符号选择器 Without 任何过渡，其中表情符号选择器的布局高度与我的键盘相同(就像whatsapp 和电报)。

当我实现它并从软件键盘切换到表情符号键盘时，我的软件键盘会消失并且我的表情符号选择器的可见性将从 GONE 设置为 VISIBLE。除了由于不断变化的布局而导致丑陋的 buggy 过渡之外，它在所有设备上的尺寸也相同，而无需记住键盘具有不同的高度。我正在使用以下表情符号选择器 https://github.com/rockerhieu/emojicon

有人知道如何更改我的实现以使我的表情符号选择器与我的键盘高度相同吗？我尝试了各种方法，但都没有用。下面是我的聊天 fragment 和布局中的一些代码。

聊天 fragment

在 ChatFragment 中，我将 SoftInputMode 设置为 SOFT_INPUT_ADJUST_NOTHING，因为我试图在我的软件键盘后面加载表情符号键盘，效果非常好。我再次遇到的唯一问题是表情符号选择器的高度。当我在我的 Galaxy s3 上测试它时，它的大小与键盘相同，在我的 nexus 5 和 Galaxy Y DUO 上，布局比键盘布局大一点和小一点，所以看不见的表情符号从软件键盘上伸出来。 .

有没有人对我如何成功实现此功能而不会出现奇怪的布局故障或动画有任何提示？
