ListView sets the length of the dividing line

The default dividing line of ListView in android is to fill the width of the entire listview, and then the designer needs to be in a state that is not filled, find relevant information, and write a demo to verify.

 

Of course, the easiest way to implement it is to use a picture, but the picture needs to be related to the resolution, so it will be more direct to fill it with color.

Define the divider line I need in the drawable main_list_divider_line.xml

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
        <item
        android:left="10dp"
        android:right="10dp">
        <shape android:shape="rectangle" >
            <solid android:color="#33000000" />
        </shape>
    </item>
</layer-list>

 Among them, android:left indicates the distance from the left, android:right indicates the distance from the right, android:shape="rectangle" indicates that it is filled with a rectangle, and android:color="#33000000" fills the color.

Then set the dividing line as the above filler in the place where the listview is configured

    <ListView
        android:id="@+id/main_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:divider="@drawable/main_list_divider_line"
        android:dividerHeight="1px"
        android:layout_marginTop="14dp" >
    </ListView>
