我需要设计以下屏幕,但我不确定如何绘制一条垂直线,该线位于imageview

cardview的中心位置

我当前的xml代码是

<?xml version="1.0" encoding="utf-8"?>

</LinearLayout>

我曾使用LinearLayout作为我的父级垂直方向,现在我需要在我使用的5 cardview之间绘制垂直线。请任何建议都会有所帮助

解决问题的简单方法(它不是一个完美的解决方案,但在你的情况下,我认为这就足够了):

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:card_view="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/account_opening_grey_bg">

    <View
        android:layout_widht="1dp"
        android:layout_height="match_parent"
        android:layout_gravity="right"
        android:layout_marginRight="56dp"
        android:background="#FF785C"/> 
    <!-- You will need to vary layout_marginRight parameter -->
    <!-- to pick up correct position for asked grey stripe -->
    <!-- I assumed this value as sum of 10(padding of linearlayout), -->
    <!-- 15(margin of image in cardview), 24(half size of image) --> 
    <!-- and 7(margin of cardView), but you can change it, as I said-->

    <LinearLayout ...>
    <!-- paste here your layout but remove background for root LinearLayout-->
</FrameLayout>

您所要做的就是:

  1. 将布局根目录更改为RelativeLayout

  2. 确保所有CardView与所需的layout_below完全相同 它们之间的间距(边距)使用RelativeLayout属性

  3. 声明&#34;线路视图&#34;在根CardView内,但在XML中的CardView之后,这样当你将它们展开时,它们会出现在layout_below

  4. 之上
  5. 使用layout_aboveImageView引用顶部和下方的<View android:layout_width="2dp" android:layout_below="@id\id_of_the_image_view_at_the_top" android:layout_above="@id\id_of_the_image_view_below" /> 。例如......

  6. {{1}}

    然后确保设置边距,以便水平居中

这里..使用此布局..

    while (rs.next()) {
        out.append("<tr>");
        for (int col = 1; col < rsMeta.getColumnCount() + 1; col++) {
            out.append("<td>");
            out.append(rs.getString(col));
            out.append("</td>");
        }
        out.append("</tr>");
        cnt++;
    }
