Can not get ScrollView to scroll when soft keyboard is shown
提问by Shant
I have been trying to get this scrollview to scroll, and have not had any luck in doing so. I have tried many types of fixes but cant seem to get one working. I would like to be able to scroll through my page when an edit box is selected and the keyboard takes up half the screen. This way i can navigate to the rest of the edit boxes and the accept button on the bottom of the page, with out having to manually hide the keyboard every time.
我一直试图让这个滚动视图滚动，但没有这样做。我尝试了多种类型的修复，但似乎无法让一种修复。我希望能够在选择编辑框并且键盘占据一半屏幕时滚动浏览我的页面。这样我就可以导航到页面底部的其余编辑框和接受按钮，而不必每次都手动隐藏键盘。
Here is my xml code:

(Please someone help me figure this thing out, its driving me crazy!!). I would also like to mention that I have tried most of the fixes with people who had similar issues such as filling the view port, and enabling the vertical scroll bar, non of these helped me with my troubles. I also tried adding them to the parent layout and did not seem to work either.
（请有人帮我解决这个问题，这让我发疯了！！）。我还想提一下，我已经与有类似问题的人一起尝试了大部分修复，例如填充视口和启用垂直滚动条，但这些都没有帮助我解决问题。我也尝试将它们添加到父布局中，但似乎也不起作用。

Add android:windowSoftInputMode="adjustResize"to the <activity>tag in your AndroidManifest.xml. This will cause the screen to be resized to the space left over after the software keyboard is shown. As a result, you will be able to scroll, since the screen will not be covered by the keyboard in any way.
添加android:windowSoftInputMode="adjustResize"到<activity>AndroidManifest.xml 中的标记。这将导致屏幕调整为显示软键盘后剩余的空间。因此，您将能够滚动，因为屏幕不会以任何方式被键盘覆盖。

Hi I encountered this problem as well. The issue I had was I added adjustResize as shown below in my Manifest
你好我也遇到了这个问题。我遇到的问题是我在清单中添加了 adjustResize，如下所示
and it still wouldn't scroll. But in my xml file in the beginning of my ScrollView
它仍然不会滚动。但是在我的 ScrollView 开头的 xml 文件中
<ScrollView
android:id="@+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/top"
android:scrollbars="none" >
I deleted android:scrollbars="none" and that solved my problem. Just for anyone whose adjustment on the manifest did not work.
我删除了 android:scrollbars="none" 并解决了我的问题。仅适用于对清单的调整不起作用的任何人。
