如何在Android View中实现这种布局配置

Question

My current Android application requires a complex layout as follows.

this is the completed view

It consists of four ImageView s, (eg IV1 - 4 ) and three TextView s (eg TV1 - 3 )

There are additional restrictions I have to adhere to

• A Minimum of 1 ImageView will always be present, it can be any of the four shown
• All textViews are mandatory
• All ImageViews have identical width & height
• All Textviews heights must match that of the ImageViews

For the Top and middle rows shown above I have managed to get to the following layout

<RelativeLayout
    android:id="@+id/top_row_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingStart="10dp"
    android:paddingTop="10dp"
    android:paddingEnd="10dp">

    <ImageView
        android:id="@+id/top_left_corner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/ic_launcher_background" />

    <TextView
        android:id="@+id/top_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/top_left_corner"
        android:layout_alignWithParentIfMissing="true"
        android:layout_marginStart="4dp"
        android:layout_marginEnd="4dp"
        android:layout_toStartOf="@+id/top_right_corner"
        android:layout_toEndOf="@+id/top_left_corner"
        android:text="@string/lorem_ipsum" />

    <ImageView
        android:id="@+id/top_right_corner"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentEnd="true"
        android:src="@drawable/ic_launcher_background" />

</RelativeLayout>

<TextView
    android:id="@+id/middle_text"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"
    android:text="@string/lorem_ipsum" />

I wanted to achieve the desired UI without having to develop a custom View, I've a feeling that it may be the only solution though.

You can achieve this layout using ConstraintLayout

Try below code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:orientation="vertical"
    tools:context=".MainActivity"
    android:padding="20dp">
    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/clMain1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:padding="10dp">

        <ImageView
            android:id="@+id/ivMain1"
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintDimensionRatio="1:1"
            android:src="@mipmap/ic_launcher"/>

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            app:layout_constraintStart_toEndOf="@+id/ivMain1"
            app:layout_constraintEnd_toStartOf="@id/ivMain2"
            app:layout_constraintTop_toTopOf="@+id/ivMain1"
            app:layout_constraintBottom_toBottomOf="@+id/ivMain1"
            android:text="Text1"
            android:gravity="center"/>
        <ImageView
            android:id="@+id/ivMain2"
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintDimensionRatio="1:1"
            android:src="@mipmap/ic_launcher"/>

    </androidx.constraintlayout.widget.ConstraintLayout>
    <TextView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@+id/clMain1"
        app:layout_constraintBottom_toTopOf="@+id/clMain2"
        android:gravity="center"
        android:text="Text2"
        android:padding="10dp"/>
    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/clMain2"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        android:padding="10dp">

        <ImageView
            android:id="@+id/ivMain3"
            android:layout_width="wrap_content"
            android:layout_height="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintDimensionRatio="1:1"
            android:src="@mipmap/ic_launcher"/>

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            app:layout_constraintStart_toEndOf="@+id/ivMain3"
            app:layout_constraintEnd_toStartOf="@id/ivMain4"
            app:layout_constraintTop_toTopOf="@+id/ivMain3"
            app:layout_constraintBottom_toBottomOf="@+id/ivMain3"
            android:text="Text3"
            android:gravity="center"/>
        <ImageView
            android:id="@+id/ivMain4"

            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintDimensionRatio="1:1"
            android:src="@mipmap/ic_launcher"/>

    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.constraintlayout.widget.ConstraintLayout>
