Error al inflar la clase android.support.constraint.ConstraintLayout




(2)

Estás utilizando paquetes de androidX. Por lo tanto, debe migrar toda la biblioteca android.support con androidX.

Entonces reemplace debajo de la línea en gradle,

implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta1'

Con este,

implementation 'androidx.constraintlayout:constraintlayout:1.1.2'

Estaba trabajando en una aplicación de Android Studio cuando me encontré con este error.

Este es mi gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.example.visualizercopy"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0-beta01'
    implementation 'com.jjoe64:graphview:4.2.2'
    implementation 'com.android.support.constraint:constraint-layout:2.0.0-beta1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

}

Esta es la etiqueta de diseño de restricción en mi archivo xml

<android.support.constraint.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:id="@+id/PLAY_PARENT"
    android:padding="0dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    tools:layout_editor_absoluteY="81dp">

He examinado mi error en este sitio y en google, y la respuesta común es agregar la compile 'com.android.support.constraint:constraint-layout:1.0.2' , sin embargo, la compilación ahora es obsoleta, y cuando reemplazo compilar con implementación y lo cambié a la versión más reciente ( 'com.android.support.constraint:constraint-layout:2.0.0-beta1' ) Todavía me encuentro con el mismo error. ¿Cómo puedo arreglar esto?


Lo descubrí, tuve que actualizar las etiquetas android.support.constraint.ConstraintLayout a androidx.constraintlayout.widget.ConstraintLayout en mi diseño XML.
