Material-components-android: Error inflating com.google.android.material.button.MaterialButton

[houdayec]

Hi everyone.

I'm trying to dynamically inflate a button layout into a recycler view item from my item adapter.
Here is how it looks :

LayoutInflater factory = LayoutInflater.from(mContext); View buttonView = factory.inflate(buttonsList.get(position).getLayout(), null); holder.buttonContainer.addView(buttonView);

Basically, my getLayout attribute returns the layout id of the corresponding button item.

Layout looks like this :

<com.google.android.material.button.MaterialButton xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/material_button" style="@style/Widget.MaterialComponents.Button" android:layout_width="match_parent" android:layout_height="wrap_content" android:backgroundTint="@color/colorPrimary" android:text="Search" android:textSize="14sp" android:textAllCaps="true" android:fontFamily="@font/raleway_semibold" />

I can inflate basic buttons from the old AppCompat library, but not from the Material Design.

I get the following error :

android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class com.google.android.material.button.MaterialButton
    Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class com.google.android.material.button.MaterialButton

Do you have any idea where the problem comes from ? Is it a library bug ?

Thanks in advance,

Corentin

Try to update your app theme to inherit from Theme.MaterialComponents (or a descendant)

@houdayec I faced this issue before and it was because the android:textAppearance attribute was missing.

Just add the below attribute and your problem should be fixed.

android:textAppearance="@style/TextAppearance.MaterialComponents.Button"

@m-Samhoury I had to add yours plus another line to MaterialButton attributes:

android:theme="@style/FormButton"
android:textAppearance="@style/TextAppearance.MaterialComponents.Button"

---

Had to create my own style

<style name="FormButton" parent="Theme.MaterialComponents">
    <item name="colorOnPrimary">@android:color/holo_red_light</item>
    <item name="colorPrimary">@android:color/holo_orange_dark</item>
    <item name="colorOnSurface">@android:color/holo_orange_light</item>
</style>

Then it worked.

Change your AppTheme parent to Theme.MaterialComponents

Before

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

After

    <!-- Material application theme. -->
    <style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

android:theme="@style/FormButton"
android:textAppearance="@style/TextAppearance.MaterialComponents.Button"

[NirmalanSindujan]

check your style file whether is it define as AppCompa or MaterialComponents.
<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
if it is AppCompat yo are trying material but your global one is set to Material. Thatswhy error is showing

Issue still happening even after setting all the properties commented above. Using com.google.android.material:material:1.1.0

Try to change theme attribute into application node inside manifest file!!!
