如何將填充添加到JUST默認的列表視圖分隔符？

Question

我想添加左右填充只是我的列表視圖分隔線，因爲每行應該在屏幕的最左邊有一個純色，如果我添加填充到整個列表這些顏色也將被填充。我知道我可以製作我自己的分頻器，但我無法找到默認分頻器的可繪圖。

我試圖做這樣的繪製：

<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" /> 

然後使其分頻器：

<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> 

但應用力這一關：

Answer 1

這裏是問題android:divider需要一個@drawable或@color（請參閱docs），但您要給它一個保存在@drawable文件夾下的@layout（這就是編譯的原因），但在運行時崩潰。

android.content.res.Resources$NotFoundException: File res/drawable/list_divider.xml from drawable resource ID #0x7f020007 

不幸的是，我不認爲有引用默認的Android繪製列表分隔和同時覆蓋其填充/邊界的任何好辦法。如果你得到了drawable的源文件，你可以編輯9.png文件的可伸縮/內容區域來調整它的填充，但這很枯燥。

這是解決方法我發現（和工程只是罰款）：設置android:divider="@null"，和你的分頻器View添加到row_layout.xml的底部（即您使用綁定到你的ListView）。基本上你會僞裝分隔線，而且它會住在每一排內而不是在它們之間，但對用戶來說它看起來是一樣的。然後，您將能夠控制分隔符的填充與每行填充分開，這是您的目標。
