Trying to build a program that enables users to select image from gallery but when I run and choose the image the image doesn't appear in the app
I have been trying to fix this but I find no problem with the codes.
XML layout:
<?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"
android:padding="20sp"
tools:context=".MainActivity">
<ImageView
android:id="@+id/significant"
android:layout_width="270dp"
android:layout_height="480dp"
android:scaleType="centerCrop"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
app:layout_constraintEnd_toEndOf="@+id/significant"
app:layout_constraintStart_toStartOf="@+id/significant"
app:layout_constraintTop_toBottomOf="@+id/significant" />
</androidx.constraintlayout.widget.ConstraintLayout>
Kotlin class
package com.example.projectc
import android.app.Activity
import android.content.Intent
import android.media.Image
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
button.setOnClickListener {
Intent(Intent.ACTION_GET_CONTENT).also {
it.type = "image/*"
startActivityForResult(it, 0)
}
}
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == Activity.RESULT_OK && resultCode == 0) {
val uri = data?.data
significant.setImageURI(uri)
}
}
}
