软键盘推入隐藏操作栏或覆盖edittext [英] Soft keyboard push up hidding action bar or overlay edittext

问题描述

我有一个简单的布局问题. 如果我设置

I have an issue with a simple layout. If I set

android:windowSoftInputMode="stateHidden|adjustResize"

发生这种情况: 错误

无论如何，仅当我从横向打开键盘时，然后旋转(在键盘打开的情况下)，这种情况才会发生. 在正常使用情况下(旋转然后再打开键盘)不会发生这种情况！

In any case this happens only If I open keyboard from landscape, then rotate (with keyboard open). In normal use (rotating and then opening keyboard) this does not happens!

如果我设置

android:windowSoftInputMode="stateHidden|adjustPan"

ActionBar被推上.

ActionBar is pushed up.

推荐答案

当 SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 标志出现时，会出现此问题，该标志是显示StatusBar后面的抽屉所必需的.

The problem occurs when the SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flag, which is required to display the drawer behind the StatusBar.

作为解决方案，我实现了KeyboardUtil，它将键盘的高度作为填充添加到contentview中.由于显示键盘时没有侦听器获取事件，因此可以通过OnGlobalLayoutListener完成.

As a solution for this I implemented the KeyboardUtil which adds the height of the keyboard as padding to the contentview. As there is no listener to get an event when the keyboard is shown, this is done via a OnGlobalLayoutListener.

@MarcoCount有一个特殊的用例，导致KeyboardUtil无法正常工作.在他的帮助下，我们来到了KeyboardUtil的更新版本，该版本现在在旋转屏幕时也可以使用，并且键盘一直在显示整个时间.

@MarcoCount had a special usecase which caused the KeyboardUtil to not working correctly. With the help of him we came to an updated version of the KeyboardUtil which now also works when the screen is rotated, and the Keyboard keeps showing the whole time.

以下是更新的KeyboardUtil的来源，以防有人需要.它也可以在GitHub的 MaterialDrawer的来源

Here's the source of the updated KeyboardUtil in case someone needs it. It is also available on GitHub within the source of the MaterialDrawer
