Unleash ChatGPT’s Potential: Craft an App with One Prompt and Zero Coding Effort

I’ve made it my personal mission to set aspiring Android app developer on the path to success, so that they can experience the blessing of working for yourself fulltime and make money from Google Play.

Imagine you have an amazing app idea and the first thing you want to do is create a Profile screen where the user can enter their name, bio, and select a profile picture. Then this info will be saved using Shared Preferences.

Before a developer would have to spend time planning this out, and searching on Stack Overflow and other forums about how to proceed. Searching desperately for code snippets that work, and then spending time debugging that code.

Not any more! In this post I’ll show you my method for implementing the profile screen into a new Android Studio project using the Kotlin programming language with just one prompt to ChatGPT!

Getting Started: The Magic Prompt

Here’s the magic prompt that I used to get the instructions and code from ChatGPT to create the profile screen that I wanted:

Please give me the code and step by step instructions for creating a new profile fragment in Android Studio in a new empty activity project that uses view binding. I want the fragment to use a cardview and text formatting so that it’s sleek and modern looking. I want the user to be able to enter their name, bio, and select a profile picture from their device. Then we display this in the profile fragments layout. We also need to display the profile fragment in the MainActivity. We’ll save the info in shared preferences and load it on activity created. If your output is cutoff I will prompt with continue.

ChatGPT Works It’s Magic: The Output

Here’s the response from ChatGPT, giving me working step by step instructions to implement a modern, sleek, material design profile fragment using Android app development best practices.

Creating a profile fragment in Android Studio involves several steps. Here’s a step-by-step guide to help you through the process:

1. Add dependencies to the build.gradle (Module) file:

First, you’ll need to add the required dependencies to your app-level build.gradle file:

dependencies {
    implementation 'com.google.android.material:material:1.4.0'
    implementation 'androidx.cardview:cardview:1.0.0'
    implementation 'androidx.fragment:fragment-ktx:1.3.6'
}

Sync the Gradle files after adding the dependencies.

2. Create a new Fragment:

In the Project window, right-click on the package where you want to create the fragment, then select New -> Fragment -> Fragment (Blank). Name it “ProfileFragment” and make sure to check “Use view binding” and “Include fragment factory methods” options.

3. Update the fragment_profile.xml layout file:

Replace the content of the `fragment_profile.xml` file with the following code:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".ProfileFragment">
    <androidx.cardview.widget.CardView
        android:id="@+id/cardView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:layout_marginEnd="16dp"
        app:cardCornerRadius="8dp"
        app:cardElevation="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">
        <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="16dp">
            <ImageView
                android:id="@+id/profile_image"
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:scaleType="centerCrop"
                android:src="@mipmap/ic_launcher_round"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent" />
            <EditText
                android:id="@+id/name_input"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginStart="16dp"
                android:hint="Name"
                app:layout_constraintBottom_toTopOf="@+id/bio_input"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toEndOf="@+id/profile_image"
                app:layout_constraintTop_toTopOf="@+id/profile_image" />
            <EditText
                android:id="@+id/bio_input"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_marginTop="8dp"
                android:hint="Bio"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="@+id/name_input"
                app:layout_constraintTop_toBottomOf="@+id/name_input" />
        </androidx.constraintlayout.widget.ConstraintLayout>
    </androidx.cardview.widget.CardView>
</androidx.constraintlayout.widget.ConstraintLayout>

Update ProfileFragment.kt:

Update your `ProfileFragment.kt` file to include the logic for selecting a profile picture, saving and loading data in SharedPreferences:

import android.app.Activity.RESULT_OK
import android.content.Context
import android.content.Intent
import android.content.SharedPreferences
import android.graphics.Bitmap
import android.graphics.BitmapFactory
import android.os.Bundle
import android.provider.MediaStore
import androidx.fragment.app.Fragment
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.core.graphics.drawable.toBitmap
import java.io.ByteArrayOutputStream
class ProfileFragment : Fragment() {
    private var _binding: FragmentProfileBinding? = null
    private val binding get() = _binding!!
    private lateinit var sharedPreferences: SharedPreferences
    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        _binding = FragmentProfileBinding.inflate(inflater, container, false)
        sharedPreferences = requireActivity().getSharedPreferences("profile_data", Context.MODE_PRIVATE)
        // Load saved data
        loadProfileData()
        binding.profileImage.setOnClickListener {
            selectProfileImage()
        }
        binding.nameInput.setOnFocusChangeListener { _, hasFocus ->
            if (!hasFocus) saveProfileData()
        }
        binding.bioInput.setOnFocusChangeListener { _, hasFocus ->
            if (!hasFocus) saveProfileData()
        }
        return binding.root
    }
    private fun selectProfileImage() {
        val pickIntent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
        startActivityForResult(pickIntent, 1000)
    }
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == 1000 && resultCode == RESULT_OK && data != null) {
            val imageUri = data.data
            binding.profileImage.setImageURI(imageUri)
            saveProfileData()
        }
    }
    private fun saveProfileData() {
        val editor = sharedPreferences.edit()
        editor.putString("name", binding.nameInput.text.toString())
        editor.putString("bio", binding.bioInput.text.toString())
        val bitmap = binding.profileImage.drawable.toBitmap()
        val baos = ByteArrayOutputStream()
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos)
        val byteArray = baos.toByteArray()
        editor.putString("profile_image", byteArray.joinToString(separator = ","))
        editor.apply()
    }
    private fun loadProfileData() {
        binding.nameInput.setText(sharedPreferences.getString("name", ""))
        binding.bioInput.setText(sharedPreferences.getString("bio", ""))
        val profileImageString = sharedPreferences.getString("profile_image", "")
        if (profileImageString!!.isNotEmpty()) {
            val byteArray = profileImageString.split(",").map { it.toByte() }.toByteArray()
            val bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.size)
            binding.profileImage.setImageBitmap(bitmap)
        }
    }
    override fun onDestroyView() {
        super.onDestroyView()
        _binding = null
    }
}

Display the ProfileFragment in MainActivity:

Replace the content of your `activity_main.xml` file with the following code to add a FrameLayout as a container for the ProfileFragment:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <FrameLayout
        android:id="@+id/fragment_container"
         android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />
    
</androidx.constraintlayout.widget.ConstraintLayout>

Update your `MainActivity.kt` file to display the ProfileFragment:

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import androidx.fragment.app.commit
class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        if (savedInstanceState == null) {
            supportFragmentManager.commit {
                setReorderingAllowed(true)
                add(R.id.fragment_container, ProfileFragment())
            }
        }
    }
}

Now you should have a functioning ProfileFragment that uses a CardView with a sleek and modern look, allowing users to enter their name, bio, and select a profile picture from their device. The entered data will be saved in SharedPreferences and loaded when the activity is created.

That’s It: One Prompt and Done

That’s all it took to get our profile screen up and running. Trust me, without ChatGPT this would have taken much longer. We didn’t even have to write a single line of our own code, mind blown!
