附上图片以供理解：
我怎样才能理解发生了什么？我以前用过ViewTreeObserver。
U.P.D.
我的目标是
我希望内容在键盘出现时向上移动，但键盘却覆盖了它。
一切实际上都按照您的布局构建方式的预期工作 -- 页边距是固定的距离，因此您的 UI 对于较小的屏幕来说太高了。您需要修改您的布局以更好地适应小型布局 - 要么将不必要的视图（例如徽标）标记为消失（ConstraintLayout 会将 "gone" 视图视为折叠到一个点，本质上 - 所以布局仍然有效），或将一些边距尺寸更改为较小的值。
构建它的常用方法是使用 bias constraints or guidelines，而不是硬边距。使用偏差或准则（在百分比模式下）将允许您有更多类似 "spring" 的行为以更好地对尺寸变化做出反应。通常，布局会混合硬边距和偏差/准则。
总而言之，您的选择是：
- 更改布局以使用偏差/准则（百分比）约束以获得更具响应性的布局
- 检测到键盘时将某些视图标记为
GONE
- 动态更改一些其他值（字体大小、边距值...）
- 或者，创建另一个布局文件来处理这种情况
我不确定您的片段位于 Activity 中，但如果它位于例如 InitChatActivity 中，只需将 adjustResize 添加到您的清单中，并将您的 ConstraintLayout 包装在 ScrollView 或 NestedScrollView 中：
android:windowSoftInputMode="stateHidden|adjustResize"
我遇到了和你一样的问题，我们在AndroidManifest.xml中声明了android:windowSoftInputMode="stateAlwaysHidden|adjustResize"，但实际上App显示的结果是adjustPan，上面的内容都没有了软键盘。所以我以编程方式设置adjustResize，成功解决了这个问题：
只需将此行添加到您的 onCreate:
getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
为我工作（在视图中）:
android:fitsSystemWindows="true"
android:focusableInTouchMode="true"
之前软输入模式没有问题，但包含ConstraintLayout后，出现键盘时片段内容不上移
