Set buttons inline and break line to fit different devices

问题

I want to add some buttons in a line and break it in a new line when they reach the end of the screen:

If you know CSS, what I need is similar to display: inline-block rule.

I am looking for a XML solution only, I want to avoid measuring the screen and buttons using java to emplace them below programatically.

This is my current code, the following buttons are inside a ConstraintLayout:

    <Button
        android:id="@+id/boton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        android:text="Imagen"        />
    <Button
        android:id="@+id/boton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toRightOf="@id/boton1"
        android:text="Play"        />
    <Button
        android:id="@+id/boton3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toRightOf="@id/boton2"
        android:text="Audio"        />
    <Button
        android:id="@+id/boton4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toRightOf="@id/boton3"
        android:text="Play"
        android:onClick="playVideo"        />
    <Button
        android:id="@+id/boton5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toRightOf="@id/boton4"
        android:text="Youtube"        />
    <Button
        android:id="@+id/boton6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toRightOf="@id/boton5"
        android:text="Raw"        />

since last time, I found this library that you should enjoy ! github.com/google/flexbox-layout

In your case, you should use the flexWrap attribute :

This attribute controls whether the flex container is single-line or multi-line, and the direction of the cross axis. Possible values are:

• nowrap (default)
• wrap (use this)
• wrap_reverse

You will be able to wrap your buttons.

Installation

Add the following dependency to your build.gradle file:

dependencies {
    implementation 'com.google.android:flexbox:1.1.0'
}

Usage

FlexboxLayout that extends the ViewGroup like LinearLayout and RelativeLayout. You can specify the attributes from a layout XML like:

<com.google.android.flexbox.FlexboxLayout
    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="match_parent"
    app:flexWrap="wrap"
    app:alignItems="stretch"
    app:alignContent="stretch" >

    <TextView
        android:id="@+id/textview1"
        android:layout_width="120dp"
        android:layout_height="80dp"
        app:layout_flexBasisPercent="50%"
        />

    <TextView
        android:id="@+id/textview2"
        android:layout_width="80dp"
        android:layout_height="80dp"
        app:layout_alignSelf="center"
        />

    <TextView
        android:id="@+id/textview3"
        android:layout_width="160dp"
        android:layout_height="80dp"
        app:layout_alignSelf="flex_end"
        />
</com.google.android.flexbox.FlexboxLayout>

Have you tried using gridLayout ?

<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnCount="4">

    <Button
        android:id="@+id/boton1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Imagen"        
        />
    <Button
        android:id="@+id/boton2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Play"
        />
    <Button
        android:id="@+id/boton3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Audio"
        />
    <Button
        android:id="@+id/boton4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Play"
        android:onClick="playVideo"
        />
    <Button
        android:id="@+id/boton5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Youtube"
        />
    <Button
        android:id="@+id/boton6"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Raw"
        />

</GridLayout>`
