Button text vertical alignment is off in Android
提问by jvergeldedios
I'm having trouble with button text alignment in my Android app. I have a button defined in XML like this:
我在 Android 应用程序中遇到按钮文本对齐问题。我有一个用 XML 定义的按钮，如下所示：
<Button
android:id="@+id/reportanissuebutton"
android:layout_width="272sp"
android:layout_height="32sp"
android:text="@string/button_report_issue"
android:textColor="#fff"
android:textSize="18sp"
android:gravity="center_vertical|center_horizontal"
android:background="@xml/report_issue_button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="40sp"/>
The result is this:
结果是这样的：
I was expecting the text to be centered both vertically and horizontally as it does with all of the other buttons in my application, but for some reason with this one it is offset slightly down. I can't seem to figure out why its doing this, so any help would be appreciated.
我希望文本能够垂直和水平居中，就像我的应用程序中的所有其他按钮一样，但由于某种原因，它稍微向下偏移。我似乎无法弄清楚为什么要这样做，因此将不胜感激。
Edit: Here is the XML for the background of the button:
编辑：这是按钮背景的 XML：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="6dp" />
<stroke android:color="#c2c2c2" android:width="2dp" />
<gradient
android:angle="90"
android:startColor="#000"
android:endColor="#919191"/>
</shape>

Try this: dip will size on different devices much better than sp and declaring no gravity is by default completely centered
试试这个：dip 在不同设备上的尺寸比 sp 好得多，并且默认情况下没有重力完全居中
<Button
android:id="@+id/reportanissuebutton"
android:layout_width="272dip"
android:layout_height="32dip"
android:text="@string/button_report_issue"
android:textColor="#fff"
android:textSize="18dip"
android:background="@xml/report_issue_button"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="40sp"/>
Additionally: This exact thing happened to me when the font was too tall for the button try decreasing the size of the font slightly and/or increasing the height of the button.... this solved my issue.
另外：当按钮的字体太高时，这正是发生在我身上的事情，尝试稍微减小字体的大小和/或增加按钮的高度......这解决了我的问题。

If you are building your view programmatically, use this:

I had an issue with the vertical text alignment.
Turned out, it happened because of increased vertical line spacing (at the button's parent style) by setting android:lineSpacingExtra.
So make sure you do not have it specified or set android:lineSpacingExtra="0dp"(in case you have to override parent style).
我遇到了垂直文本对齐问题。
事实证明，这是因为设置android:lineSpacingExtra.
所以请确保您没有指定或设置它android:lineSpacingExtra="0dp"（以防您必须覆盖父样式）。

S really complete answer is this..
真正完整的答案是这个..
<item name="android:includeFontPadding">false</item>
<item name="android:paddingTop">0dp</item>
<item name="android:paddingBottom">0dp</item>
..in some cases when desired button height is too small compared to font size.
..在某些情况下，与字体大小相比，所需的按钮高度太小。
