我想在我的listview分隔符中添加左右填充,因为每行应该在屏幕的最左侧有一个纯色,如果我在整个列表中添加填充,那么这些颜色也会被填充。我知道我可以制作自己的分频器,但我无法找到默认分频器的可画面。
我试图像这样做一个可绘制的:
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:background="?android:attr/listDivider" />
然后将其作为分隔符:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/background_pattern" >
<ListView
android:id="@+id/status_list"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:divider="@drawable/list_divider"
android:headerDividersEnabled="false"
android:footerDividersEnabled="false" >
</ListView>
但应用程序部队以此结束:

答案 0 :(得分:2)
以下是问题,android:divider
需要@drawable
或@color
(请参阅docs),但您在@layout
下保存了@drawable
{1}}文件夹(这就是它编译的原因),但在运行时崩溃。
android.content.res.Resources$NotFoundException: File res/drawable/list_divider.xml from drawable resource ID #0x7f020007
不幸的是,我认为没有任何好方法可以引用默认的android drawable list divider AND 同时覆盖其填充/边界。如果你得到了drawable的源文件,你可以编辑9.png文件的可伸缩/内容区域来调整它的填充,但这是相当繁琐的。
这是我找到的解决方法(并且运行正常):设置android:divider="@null"
,并将分隔符View
添加到row_layout.xml
的底部(用于绑定到ListView
)。基本上你会伪造分频器,它会在每一行内而不是在它们之间,但对于用户来说它看起来是一样的。然后,您将能够控制分隔线的填充与每行的填充分开,这是您的目标。
