Android ImageView

ImageView:

ImageView is a user interface detail that is used to show pix or drawables within an app's format.

It is a versatile and normally used widget for presenting visible content material, which includes icons, pics, or images.

ImageView inherits from the View class and is designed particularly for managing pix.

Example:

                                    
                                            <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".ImageViewExample"
        android:orientation="vertical"
        android:gravity="center">
    
        <ImageView
           android:id="@+id/image"
           android:layout_width="300dp"
           android:layout_height="200dp"
           android:src="@drawable/imageview"
           />
   
   </LinearLayout>

                                    
                                            package com.example.widgets;
                                            
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.Toast;
                                            
public class ImageViewExample extends AppCompatActivity {
                                           
    ImageView imageView;
                                           
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_image_view_example);
        imageView=(ImageView)findViewById(R.id.image);
        imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(),"ImageView clicked by you.",Toast.LENGTH_SHORT).show();
            }
        });
    }
}

                                    
                                        package com.example.widgets

import android.os.Bundle
import android.view.View
import android.widget.ImageView
import android.widget.Toast
import androidx.appcompat.app.AppCompatActivity

class ImageViewExample : AppCompatActivity() {

    private lateinit var imageView: ImageView

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_image_view_example)

        imageView = findViewById(R.id.image)
        imageView.setOnClickListener {
            Toast.makeText(applicationContext, "ImageView clicked by you.", Toast.LENGTH_SHORT).show()
        }
    }
}
