分步实施

第一步:新建布局资源文件

转到 app > res >布局>右键>新建>布局资源文件并将文件命名为 row_comments。下面是 row_comments.xml 文件的代码。

XML

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="1dp"
    android:orientation="vertical"
    app:cardBackgroundColor="@color/colorWhite"
    app:contentPadding="2dp">

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

        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/loadcomment"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginEnd="5dp"
            android:layout_marginRight="5dp"
            android:src="@drawable/profile_image" />

        <TextView
            android:id="@+id/commentname"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@id/loadcomment"
            android:text="Anni"
            android:textColor="@color/colorBlack"
            android:textSize="16sp"
            android:textStyle="bold" />

        <TextView
            android:id="@+id/commenttext"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/commentname"
            android:layout_toEndOf="@id/loadcomment"
            android:layout_toRightOf="@id/loadcomment"
            android:text="Actual Comment"
            android:textColor="@color/colorBlack" />

        <TextView
            android:id="@+id/commenttime"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/commenttext"
            android:layout_toEndOf="@id/loadcomment"
            android:layout_toRightOf="@id/loadcomment"
            android:text="12/06/19" />
