TextInputLayout throws "The style on this component requires your app theme to be Theme.AppCompat (or a descendant)."

Question

I am using TextInputLayout wrapped around a EditText for a RecyclerView item. I am using style "Theme.AppCompat.Light.NoActionBar". But still I get the error "Caused by: java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.AppCompat (or a descendant)." However when I remove the TextInputLayout from the xml, the App runs fine.

Here is my RecyclerView item (item_content_settings):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:weightSum="20">

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="18"
        android:padding="16dp">

        <EditText
            android:id="@+id/content_summary"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="First Name"
            android:inputType="text"
            android:text="First Name And Last Name" />

    </com.google.android.material.textfield.TextInputLayout>

    <ImageView
        android:id="@+id/pencil"
        android:layout_width="0dp"
        android:layout_height="16dp"
        android:layout_gravity="center"
        android:layout_margin="0dp"
        android:layout_weight="2"
        android:src="@drawable/pencil_edit" />
</LinearLayout>

Any thoughts? Thanks.

Answer 1

As @MikeM. commented on the question there is an issue with the context used to instantiate the Adapter. You need to pass the Activity, not an Application Context.
The ApplicationContext doesn't have your app theme.

But pay attention because you are using the com.google.android.material.textfield.TextInputLayout, check the doc of the Material Components library.
Your app theme should inherit from a Material Components theme.

If you can't change your theme, you can do one of the following:

• Inherit from one of our Material Components Bridge themes.
• Continue to inherit from an AppCompat theme and add some new theme attributes to your theme.

Answer 2

If there are components in the activity that use that context, another solution would be to get the Context object, and set its theme to AppCompat. Here's the Kotlin code example:

 val context: Context = getApplicationContext()
 context.setTheme(R.style.your_theme_extending_AppCompatTheme)
 // Use this context throughout the class.
