我有两行ImageButton。在单击第一行中的任何一行后，我希望第一行被移除，第二行出现，ImageButton居中。А。它应该看起来像这样："https://lifehacker.ru/special/travel-checklist/“。

第一行的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/mainlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#bbbbbb"
    android:orientation="horizontal">


    <ImageButton
        android:id="@+id/winter"
        android:layout_width="192dp"
        android:layout_height="183dp"
        android:layout_alignParentRight="true"
        android:layout_gravity="center"
        android:layout_weight="2"
        android:gravity="left|center_vertical"
        android:onClick="Winter"
        android:paddingTop="32sp"
        android:scaleType="fitCenter"
        android:src="@drawable/snejinka"
        android:text="Зима"
        android:textColor="#FFFFFF" />


    <ImageButton
        android:id="@+id/Middle"
        android:layout_width="192dp"
        android:layout_height="183dp"
        android:layout_alignParentRight="true"
        android:layout_gravity="center"
        android:layout_weight="2"
        android:gravity="left|center_vertical"
        android:onClick="Middle"
        android:paddingTop="32sp"
        android:scaleType="fitCenter"
        android:src="@drawable/listok"
        android:text="Весна/Осень"
        android:textColor="#FFFFFF" />

    <ImageButton
        android:id="@+id/Summer"
        android:layout_width="192dp"
        android:layout_height="183dp"
        android:layout_alignParentRight="true"
        android:layout_gravity="center"
        android:layout_weight="2"
        android:gravity="left|center_vertical"
        android:onClick="Summer"
        android:paddingTop="32sp"
        android:scaleType="fitCenter"
        android:src="@drawable/unnamed"
        android:text="Лето"
        android:textColor="#FFFFFF" />


</LinearLayout>

第二行的布局：

<ImageButton
            android:id="@+id/three"
            android:layout_width="192dp"
            android:layout_height="183dp"
            android:layout_alignParentRight="true"
            android:layout_weight="2"
            android:gravity="left|center_vertical"
            android:onClick="three"
            android:paddingTop="32sp"
            android:scaleType="fitCenter"
            android:src="@drawable/three"
            android:text="three"
            android:textColor="#FFFFFF" />
        <ImageButton
            android:id="@+id/seven"
            android:layout_width="192dp"
            android:layout_height="183dp"
            android:layout_alignParentRight="true"
            android:layout_weight="2"
            android:gravity="left|center_vertical"
            android:onClick="seven"
            android:paddingTop="32sp"
            android:scaleType="fitCenter"
            android:src="@drawable/seven"
            android:text="three"
            android:textColor="#FFFFFF" />
        <ImageButton
            android:id="@+id/fourteen"
            android:layout_width="192dp"
            android:layout_height="183dp"
            android:layout_alignParentRight="true"
            android:layout_weight="2"
            android:gravity="left|center_vertical"
            android:onClick="fourteen"
            android:paddingTop="32sp"
            android:scaleType="fitCenter"
            android:src="@drawable/fourteen"
            android:text="three"
            android:textColor="#FFFFFF" />

下面是我针对这两行的活动。我不知道，如何让第二行在第一次点击后出现(第二行在评论下)

单击第一行中的几个ImageButton项后，您可以在具有多个ImageButton的线性布局中播放可见性。

你可以试试这段代码。

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_gravity="center"
    tools:context=".MainActivity">

    <LinearLayout
        android:id="@+id/layoutRowOne"
        android:orientation="horizontal"
        android:background="@android:color/holo_blue_light"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <Button
            android:text="YES"
            android:id="@+id/btnLayoutOneYes"
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

        <Button
            android:text="NO"
            android:id="@+id/btnLayoutOneNo"
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    </LinearLayout>

    <LinearLayout
        android:id="@+id/layoutRowTwo"
        android:orientation="horizontal"
        android:visibility="gone"
        android:background="@android:color/holo_orange_light"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <Button
            android:text="HOT"
            android:id="@+id/btnLayoutTwoHot"
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

        <Button
            android:text="COLD"
            android:id="@+id/btnLayoutTwoCold"
            android:layout_weight="1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    </LinearLayout>

</LinearLayout>

MainActivity

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {
    private var statusRowOne = false
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        btnLayoutOneYes.setOnClickListener {
            statusRowOne = true
            if (statusRowOne) {
                layoutRowOne.visibility = View.GONE
                layoutRowTwo.visibility = View.VISIBLE
            }
        }
        btnLayoutOneNo.setOnClickListener {
            statusRowOne = true
            if (statusRowOne) {
                layoutRowOne.visibility = View.GONE
                layoutRowTwo.visibility = View.VISIBLE
            }
        }
    }
}

我希望这段代码能帮助你解决问题。

您可以使用线性布局和框架布局将它们分开，并根据单击事件显示图像按钮。
