Error inflating class androidx.constraintlayout.ConstraintLayout after migration to androidx

Question

I just made a migration to androidx through Android Studio menu option Refactor -> Refactor to AndroidX

I\'m getting the following

Answer 1

change your constraint layout dependancy to implementation 'androidx.constraintlayout:constraintlayout:2.0.2'

Answer 2

Make Sure you have added the dependency for constraint layout

 dependencies  {
    implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}

and have made the changes to

<androidx.constraintlayout.widget.ConstraintLayout instead of

<android.support.constraint.ConstraintLayout

Answer 3

I has same issue after:

• migration support library to androidx;
• increment targetSdkVesrsion to 29;

I also use:

implementation "uk.co.chrisjenx:calligraphy:2.3.0"

I tried all posts from this question, but none success.

I fix it by adding one string .disableCustomViewInflation() to Calligraphy init:

@Override
public void onCreate() {

    super.onCreate();
    // ...
    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
            .setDefaultFontPath("fonts/Sans-Regular.ttf")
            .setFontAttrId(R.attr.fontPath)
            .disableCustomViewInflation() // <----- this fix
            .build());
    // ...
}

I hope next release of Calligraphy (Christopher Jenkins thanks for your great job) will fix it inside too.

Answer 4

1. Find all default before to click Refactor -> Refactor to AndroidX
2. Open this https://developer.android.com/jetpack/androidx/migrate/class-mappings and find "android.support.v4.widget.DrawerLayout". In same line AndroidX class name is "androidx.drawerlayout.widget.DrawerLayout" copy it.

3. Replace all "android.support.v4.widget.DrawerLayout" to "androidx.drawerlayout.widget.DrawerLayout" in your project"s code, layout and menu. After all replace it will work.

I mean find mapping and use it in whole project.

Answer 5

I had the same problem, I resolved it as follows:

In your dependecies if you have added

implementation 'androidx.constraintlayout:constraintlayout:1.x.x' that is correct

but in your xml layout file you have to use the widget as

androidx.constraintlayout.widget.ConstraintLayout

Answer 6

I solve my problem by changing all occurrences of

androidx.constraintlayout.ConstraintLayout

to

androidx.constraintlayout.widget.ConstraintLayout
