step 1:-

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:orientation="vertical"
    android:gravity="center_horizontal"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <androidx.cardview.widget.CardView

        android:layout_height="100dp"
        android:layout_marginTop="20dp"
        app:cardCornerRadius="50dp">
        <ImageView

        android:textColor="@color/white"
        android:backgroundTint="#FF5722"
        android:id="@+id/btnSave"/>


</LinearLayout>

step 2:-

MainActivity.java

package com.sandhya.cameraopen;

import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;

import android.annotation.SuppressLint;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

    ImageView imgOpenCamera, imgCamera;
    private static final int CAMERA_REQ_CODE = 100;
    private static final int GALLERY_REQ_CODE = 100;

    @SuppressLint("MissingInflatedId")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        imgCamera = findViewById(R.id.imgCamera);
        imgOpenCamera = findViewById(R.id.imgOpenCamera);
        imgOpenCamera.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent iCamera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(iCamera, CAMERA_REQ_CODE);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode,Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            if (requestCode == CAMERA_REQ_CODE) {
                //for camera
                Bitmap img = (Bitmap) (data.getExtras().get("data"));
                imgCamera.setImageBitmap(img);
            }
        }
