Setting up a Material Components theme for your Android Application

Recently we migrated one of our old application to Androidx and then we came across this Material components which we can use for our app. This posts details only changes required to migrate your app from AppCompat theme to Material Design theme. Other details of Material components can be seen on its website.

Modify app/build.gradle to add material library dependency as,

dependencies {
    implementation ''

Create a new theme in app/src/main/res/values/styles.xml

<style name="MaterialAppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

If you are porting an old AppTheme, then you can change below code from,

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">


<style name="MaterialAppTheme" parent="Theme.MaterialComponents.DayNight">

Modify your app/src/main/AndroidManifest.xml and modify your all the activities for which you want to use material theme using “android:theme” as below,

     android:windowSoftInputMode="stateHidden|adjustResize" />

Now, you are all set to use the material theme. Just compile and try on your Mobile.

Possible Errors

  1. If you get an errors like “AndroidRuntime: Caused by: android.view.InflateException: Binary XML file line” “Error inflating class” as shown below at the run time while opening your application,
AndroidRuntime: FATAL EXCEPTION: main
AndroidRuntime: Process:, PID: 19292
AndroidRuntime: android.view.InflateException: Binary XML file line #57 in Binary XML file line #57 in Error inflating class
AndroidRuntime: Caused by: android.view.InflateException: Binary XML file line #57 in Error inflating class

03-06 22:09:35.904 19292 19292 E AndroidRuntime: 	at java.lang.reflect.Constructor.newInstance0(Native Method)

This can be fixed by changing themes for your text views from,

<style name="EditTextviewStyle" parent="TextAppearance.AppCompat">


<style name="EditTextviewStyle" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">


2. If you get an error related to multidex, you can fix it by adding “multiDexEnabled true” into app/build.gradle as

android {
    defaultConfig {
        multiDexEnabled true

If you want to use this theme as full screen then you can modify as,

<style name="MaterialAppThemeFullScreen" parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="otpViewStyle">@style/OtpWidget.OtpView</item>

    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
