在我的 android 应用程序中，我有一个聊天 Activity ，我使用 android-chat-starter 中的此代码

问题出在模拟器中，一切正常，我在多种类型的模拟器中进行了测试(api >18，api =18，api <18)>

表情符号 View 显示在键盘上方

这是我用来显示表情符号 View 的代码

  private void showEmojiPopup(boolean show) {

            emojiView.setListener(new EmojiView.Listener() {
                public void onBackspace() {
                    chatEditText1.dispatchKeyEvent(new KeyEvent(0, 67));
                }

                public void onEmojiSelected(String symbol) {
                    int i = chatEditText1.getSelectionEnd();

当键盘可见时会出现问题，但如果它不可见，则表情符号 View 可以正常工作

最佳答案

不幸的是，对于 Android 5.0(不知道之后)没有办法获得键盘高度。所以你不能使用这个值来定位你的 View 。

但是，您可以使用 softKeyboard 重新布局来做您想做的事情，通过使用值为“resize”的 softKeyboard(在 Activity list 中)将使您的根布局 View 调整为剩余屏幕空间的大小.通过将 View 定位在底部，将使其正好位于键盘顶部。

PS:另外，你的 Root View 需要它的高度值是 match_parent 而不是其他任何东西(或者你需要以其他方式处理)

也许您的意思是您想要替换键盘位置而不是在“顶部”(NORTH？)，在这种情况下，您应该使用扩展 View 的 CustomView 而不是使用打开键盘的 EditText你
