在键盘存在时隐藏“底部导航栏” - Android
Hiding ‘Bottom Navigation Bar’ whilst keyboard is present - Android
我有一个小型演示聊天 UI 应用程序。此应用程序有一个底部导航栏。我需要在键盘出现时隐藏底部导航栏。
Here is an example of the chat UI
正如您在 EditText 元素中单击时看到的那样，键盘出现但底部导航栏保持可见。 this measurement method, but the UI elements flicker like this.
等方法我都试过了
有没有合适的方法在键盘可见时隐藏底部导航栏？
编辑：
在下面activity你可以看到当键盘被确定为可见时，我在哪里设置键盘监听器来调整UI元素的位置。
这是我的 activity 代码，使用上面的 setKeyboardListener 方法 link 并在 onCreateView:

我最终使用了高度测量方法，这似乎是this answer. However, I used this library's实现中描述的软键盘检测的标准方法，因为它仍然是相同的ViewTreeObserver.OnGlobalLayoutListener方法，实施得很好，并允许我从我的应用程序主代码库中提取代码。
当这个键盘可见性侦听器被触发时，我然后 hide/show 底部导航栏（我已经解释过 ）。
在我的例子中，我使用 DrawerLayout 作为具有一些布局内容和导航底部栏的父视图。
在 Manifest 文件中添加 "android:windowSoftInputMode="adjustPan" 这个带有 Activity 的 TAG 并且工作正常。
你只需像这样在你的清单中添加这段代码..
<activity android:name=".MainActivity"
android:windowSoftInputMode="adjustPan">
这对我有用..编码愉快
在您的 Activity 或 Fragment 的 onResume() 中添加此行。
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);
对我有用。试一次就可以了。
只需将下面的属性添加到 AndroidManifest.xml 文件中的每个 activity。
<activity
android:name=".MainActivity"
android:windowSoftInputMode="stateAlwaysHidden|adjustPan" />
在您的片段中添加这个 onResume()
@Override
public void onResume() {
Objects.requireNonNull(getActivity()).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_NOTHING);
super.onResume();

该解决方案对我有用，而且它也不显示重叠的底部导航栏
只需将此行添加到您的 activity:
android:windowSoftInputMode="adjustResize|adjustPan"
该答案可能对仍在寻找解决方案的人有所帮助。
主动监听 Keyboard(IME) open/close 事件和相应的 show/hide 底部导航。
我们可以利用 WindowInsetsCompat API 让这项工作毫不费力。
第 1 步：确保您已迁移到 AndroidX
第 2 步： 在你的 Fragment 里面 onCreateView 添加键盘（IME）事件的监听器
ViewCompat.setOnApplyWindowInsetsListener(window.decorView.rootView) { _, insets ->
//This lambda block will be called, every time keyboard is opened or closed
val imeVisible = insets.isVisible(WindowInsetsCompat.Type.ime())
if(imeVisible){
//Now show-hide bottom navigation accordingly
}
insets
}
这就是您所需要的
有关 window 插图的更多信息，您可以查看此 in-depth article
注意：
早期检测键盘 open/close 事件并非易事。 Android 开发人员使用了所有类型的黑客手段来实现这一目标。但经过几十年的请求、祈祷和咆哮 Google 终于想出了 WindowInsets API。谢谢 Google
