错误：错误：找不到与给定名称匹配的资源（在'paddingBottom'处，值为'@ dimen / activity_vertical_margin'）。 [英] error: Error: No resource found that matches the given name (at 'paddingBottom' with value '@dimen/ activity_vertical_margin').

问题描述

android:paddingBottom="@dimen/activity_vertical_margin"
   android:paddingLeft="@dimen/activity_horizontal_margin"
   android:paddingRight="@dimen/activity_horizontal_margin"
   android:paddingTop="@dimen/activity_vertical_margin"

这4行给出错误！ whay？

these 4 line give error ! whay ?

推荐答案

您需要在 res / values / dimens.xml 中声明 activity_vertical_margin 。



Ex：

You need to declare activity_vertical_margin in the res / values / dimens.xml.

Ex:

<dimen name="activity_vertical_margin">5dp</dimen>

activity_main.xml



< LinearLayout xmlns：android =http://schemas.android.com/apk/res/android

xmlns：tools =http://schemas.android.com/toolsandroid：layout_width =match_parent

android：orientation =vertical

android：layout_height =match_parentandroid：paddingLeft =@ dimen / activity_horizo​​ntal_margin

android：paddingRight =@ dimen / activity_horizo​​ntal_margin

android： paddingTop =@ dimen / activity_vertical_margin

android：paddingBottom =@ dimen / activity_vertical_margintools：context =。MainActivity>





解决方案



< br $>
dimean.xml



<？xml version =1.0encoding =utf-8？>

< resources>

< dim en name =activity_horizo​​ntal_margin> 5dp

< dimen name =activity_vertical_margin> 5dp

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">


soluation below


dimean.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<dimen name="activity_horizontal_margin">5dp
<dimen name="activity_vertical_margin">5dp

这对我有用，去吧安卓工作室，点击 res 然后右键点击值然后点击*新*然后点击*值资源文件*并命名为维然后单击完成。之后你粘贴下面的代码

This worked for me, go to android studio, click on res then right click on values then click on *New* then click on *value resource file* and name it dimens then click finish. After which you paste the below code

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="activity_horizontal_margin">5dp</dimen>
    <dimen name="activity_vertical_margin">5dp</dimen>

</resources>
