Xamarin Android: Android.Views.InflateException - Error When Loading Layout

I wrote a Xamarin Android app in Visual Studio to scan QR-Barcodes. I have two layouts and two lctivitys in my project. When i start the app, the emulator loads and the App starts

Solution 1:

For every android android:layout_width and android:layout_height must be added, even with constraint layout.

The problem in your xml layout is starting from your SurfaceView, you only have android:width and android:height defined in your views.

So to resolve the problem, you need to change android:width to android:layout_width and android:height to android:layout_height.

Solution 2:

I am also face this same issue and my layout does not contain any android:width and android:height properties. I missed to add theme for my activity. I solved this issue by following steps:

Create a styles.xml file under Resources\values\ folder with below codes:

<?xml version="1.0" encoding="utf-8" ?> 
<resources>
 <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    </style>
</resources>

In MainActivity.cs define the Activity attribute to leverage AppTheme like this:

[Activity(Label = "DinexFeedback", MainLauncher = true, Icon = "@drawable/icon",Theme ="@style/AppTheme")]
public class MainActivity : Android.Support.V7.App.AppCompatActivity
{
   ...
}

Solution 3:

Unhandled Exception: Android.Views.InflateException:

Make sure the necessary nuget package installed in visual studio.

I used card view in my project, i got this issue becoz i didn't install Xamarin.Android.Support.cardview.

so we should install all support nuget package in order to support all widgets here i use card view.

click on project -> Manage Nuget-> check out the installed pakages, if the package were not installed just search the particular package and then download it.

check your layout whether all the layout fields are started with capital letter. for ex : In android we used <view> in small letter but In c# we should use <View> otherwise it throws the inflate view exception.
