Question

我有一个简单布局的问题。如果我设置

runOnUIThread()

发生这种情况： Bug

在任何情况下，只有当我从横向打开键盘然后旋转（键盘打开）时才会发生这种情况。在正常使用中（旋转然后打开键盘），这不会发生！

如果我设置

android:windowSoftInputMode="stateHidden|adjustResize"

ActionBar被推高。

这里布局代码：

android:windowSoftInputMode="stateHidden|adjustPan"

FIX： 问题出在mikepenz MaterialDrawer上。现在我联系了迈克，我们修复了错误

Answer 1

当 SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 标志出现问题时，需要显示StatusBar后面的抽屉。

作为解决方案，我实现了KeyboardUtil，它将键盘的高度添加为内容视图的填充。由于在显示键盘时没有听众可以获得事件，因此可以通过OnGlobalLayoutListener完成。

@MarcoCount有一个特殊用例导致KeyboardUtil无法正常工作。在他的帮助下，我们得到了KeyboardUtil的更新版本，现在也可以在屏幕旋转时工作，键盘会一直显示。

如果有人需要，这是更新KeyboardUtil的来源。它也可以在source of the MaterialDrawer

中的GitHub上找到

Answer 2

尝试在布局中使用滚动视图，而不是在清单文件中添加adjustpan。使用滚动视图，您的屏幕是可调节和可滚动的，这不会向上滚动您的工具栏或操作栏，也不会隐藏您的布局。

<ScrollView>
android:layout_width="match_parent"
android:layout_height="match_parent"
 android:fillViewport="true"
 android:scrollbars = "vertical"
 android:scrollbarStyle="insideInset"
> </ScrollView>

尝试将此布局用作父布局。但滚动视图不能用作基本布局，您必须在线性或相对布局中使用scrollView。

软键盘向上推隐藏动作栏或叠加编辑文本
