 //if a have a value like 'Item 3' need to set selection   val spinnerItemValue="Item 3"//some country name //find the index of the item with the target text val position = arrayList!!.indexOfFirst { it.countryName(//Note: model key which store the country   name for spinner dorp-down)==spinnerItemValue}  //set the selection in the spinner  if(position>=0){       //if you user data binding in your project        binding.countrySpinner.setSelection(position)     //if you use findViewById() in your project       Spinner countrySpinner=findViewById(R.id.countrySpinner)       countrySpinner.setSelection(position) }

  Step-1: Enable data binding to android project ADD below line to your app level build.gradle file. android {     buildFeatures {         dataBinding = true     } }  Setp-2 : Add all your XML layout design inside this <layout></layout> tag <?xml version="1.0" encoding="utf-8"?> <layout     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"> <androidx.constraintlayout.widget.ConstraintLayout     android:id="@+id/main"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".MainActivity">     <TextView         android:id="@+id/greeting_text_view"         android:layout_width="wrap_content"         android:lay...

Note: If you are seeking Java code for Jetpack Compose , please note that Jetpack Compose is only available in Kotlin . It uses features such as coroutines , and the handling of @Composable annotations is handled by a Kotlin compiler. There is no method for Java to access these. Therefore, you cannot use Jetpack Compose if your project does not support Kotlin. Step By Step Implementation Step 1: Create a New Project in Android Studio We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project. Step 2: Add the below dependency to your build.gradle File Navigate to the Gradle Scripts > build.gradle (Module:app) and add the below dependency in the dependencies section.  // below dependency for using the retrofit implementation ‘com.squareup.retrofit2:retrofit:2.9.0’ implementation ‘com.squareup.retrofit2:converter-gson:2.5.0’ After adding this dependency sync your project and now move towards the AndroidManifes...

Step by Step Implementation Step 1: Create a New Project Step 2: Add the below dependency in your build.gradle file Navigate to the Gradle Scripts > build.gradle (Module:app) and add the below dependency in the dependencies section.  // below dependency for using the retrofit implementation ‘com.squareup.retrofit2:retrofit:2.9.0’ implementation ‘com.squareup.retrofit2:converter-gson:2.5.0’ After adding this dependency sync your project and now move towards the AndroidManifest.xml part.   Step 3: Adding permissions to the internet in the AndroidManifest.xml file Navigate to the app > AndroidManifest.xml and add the below code to it.  <!--permissions for INTERNET--> <uses-permission android:name="android.permission.INTERNET"/> Step 4: Working with the activity_main.xml file Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file.  <?xml version="1.0"...
