在不使用任何库的情况下如何实现这种布局？

我尝试过类似的操作,但无法获得确切的布局

my_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="20dp"
    tools:context=".MainActivity">

    <RelativeLayout
        android:background="@drawable/layout_border"
        android:layout_margin="20dp"
        android:padding="10dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent">



        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <ImageView
                android:id="@+id/iv_tick"
                android:layout_width="17dp"
                android:layout_height="17dp"
                android:layout_marginLeft="20dp"
                android:src="@drawable/tick" />

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignBaseline="@+id/iv_tick"
                android:layout_marginLeft="14dp"
                android:layout_marginRight="20dp"
                android:layout_toRightOf="@+id/iv_tick"
                android:lineSpacingExtra="6dp"
                android:text="This is my text. This is my text. This is my text. This is my text. "
                android:textColor="#000"
                android:textSize="16dp" />
            <ImageView
                android:src="@drawable/dotted_line"
                android:foregroundGravity="left"
                android:layout_below="@+id/iv_tick"
                android:scaleType="fitXY"
                android:layout_width="match_parent"
                android:layout_height="match_parent"/>
        </RelativeLayout>


        <!--<com.example.myapplication.DividerView
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layerType="software"
            android:color="#ff0000"
            android:orientation="vertical"
            android:dashLength="5dp"
            android:dashGap="1dp"
            android:dashThickness="1dp" />-->
    </RelativeLayout>


</RelativeLayout>

dotted_line.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="90"
    android:toDegrees="90">
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
        android:shape="line">
        <stroke
            android:width="2dp"
            android:color="#ff0000"
            android:dashWidth="4dp"
            android:dashGap="4dp" />
    </shape>
</rotate>

这是我用上面实现的代码得到的结果.如何获得类似我上面发布的图像的结果？

我什至尝试了约束布局,但也没有帮助.

在可绘制文件夹名称中创建一个可绘制对象drawable / shape_round_solid

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="@color/colorAccent" />
    <size
        android:width="15dp"
        android:height="15dp" />

</shape>

添加此dimens.xml

<!--genaral spacing-->
<dimen name="spacing_xsmall">2dp</dimen>
<dimen name="spacing_small">3dp</dimen>
<dimen name="spacing_medium">5dp</dimen>
<dimen name="spacing_xmedium">7dp</dimen>
<dimen name="spacing_middle">10dp</dimen>
<dimen name="spacing_large">15dp</dimen>
<dimen name="spacing_smlarge">18dp</dimen>
<dimen name="spacing_mlarge">20dp</dimen>
<dimen name="spacing_mxlarge">25dp</dimen>
<dimen name="spacing_xlarge">35dp</dimen>
<dimen name="spacing_xmlarge">40dp</dimen>
<dimen name="spacing_xxlarge">50dp</dimen>
<dimen name="spacing_xxxlarge">55dp</dimen>
<dimen name="appbar_padding_top">8dp</dimen>

希望这对所有人都有效.
