Question

您好，我想按如下方式构建UI

我想将imageview置于textview上方，同时在imagview虚线旁边还有另一个视图我无法做到这一点。

目前我正在使用RelativeLayout。知道如何做到这一点？

以下是XML

  <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true">

        <ImageView
            android:id="@+id/ivnumberfill"
            android:layout_width="16dp"
            android:layout_height="16dp"
            app:srcCompat="@drawable/ic_otp_fill" />

        <ImageView
            android:id="@+id/ivfirstdiv"
            android:layout_width="76dp"
            android:layout_height="2dp"
            android:layout_alignBottom="@id/ivnumberfill"
            android:layout_alignTop="@+id/ivnumberfill"
            android:layout_toRightOf="@id/ivnumberfill"
            android:src="@drawable/stroke_divider" />

        <ImageView
            android:id="@+id/ivotp"
            android:layout_width="16dp"
            android:layout_height="16dp"
            android:layout_toRightOf="@+id/ivfirstdiv"
            app:srcCompat="@drawable/otp_process_circle" />

        <ImageView
            android:id="@+id/ivseconddiv"
            android:layout_width="76dp"
            android:layout_height="2dp"
            android:layout_alignBottom="@id/ivotp"
            android:layout_alignTop="@+id/ivotp"
            android:layout_centerVertical="true"
            android:layout_toRightOf="@id/ivotp"
            android:background="@drawable/stroke_divider" />

        <ImageView
            android:id="@+id/ivprofile"
            android:layout_width="16dp"
            android:layout_height="16dp"
            android:layout_toRightOf="@+id/ivseconddiv"
            app:srcCompat="@drawable/otp_process_circle" />

        <TextView
            android:id="@+id/tvnumber"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/ivnumberfill"
            android:alig="@id/ivnumberfill"
            android:text="Mobile Number"
            android:textColor="?colorAccent"
            android:textSize="11sp" />
    </RelativeLayout>

我建议使用ConstraintLayout，您应该真正学习并使用它而不是相对布局，它更灵活，耗费更少的计算量。这是我的布局，它也更灵活 - 你可以移动指南，一切都随之移动。

<?xml version="1.0" encoding="utf-8"?>
    <android.support.constraint.ConstraintLayout

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_margin="24dp">

嗯，您可以使用Constraint布局进行简单的拖放操作，它将为您提供所需的布局。

</android.support.constraint.ConstraintLayout>

示例输出，相应地更改图标和背景。

在ImageView中水平居中TextView，Imageview旁边还有另一个视图
