软键盘上推隐藏操作栏或覆盖编辑文本

Question

我对简单布局有疑问。 如果我设置

android:windowSoftInputMode="stateHidden|adjustResize"

会发生这种情况： Bug

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

如果我设置

android:windowSoftInputMode="stateHidden|adjustPan"

ActionBar 被推上去。

这里的布局代码：

修复： 问题出在 mikepenz MaterialDrawer 中。 现在我联系了迈克，我们修复了这个错误

Answer 1

尝试在布局中使用滚动视图，而不是在清单文件中添加调整盘。 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>

尝试将此布局用作您的父布局。但是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滚动视图。

Answer 2

当 SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN 标志时出现问题，这是在 StatusBar 后面显示抽屉所必需的。

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监听器来获取事件，因此这是通过OnGlobalLayoutListener 完成的。

@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，现在它在屏幕旋转时也可以工作，并且键盘一直显示。

这里是更新后的KeyboardUtil 的来源，以防有人需要。它也可以在 GitHub 上的 source of the MaterialDrawer

中找到
