I want to capture the screen from the camera and print it out in the activity

If you click the button, the camera turns on, and if you click again, you can capture the screen, if you don't like the captured image, you can delete it, go back to the screen where you can capture the screen, select it, and print it out to the activity I'd like to make something like that, so please help me.

The source below is an example of a camera app. It's an example of taking a picture and receiving it and floating it in an activity.

package edu.gvsu.cis.masl.camerademo;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class MyCameraActivity extends Activity {
    private static final int CAMERA_REQUEST = 1888; 
    private ImageView imageView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        this.imageView = (ImageView)this.findViewById(R.id.imageView1);
        Button photoButton = (Button) this.findViewById(R.id.button1);
        photoButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                startActivityForResult(cameraIntent, CAMERA_REQUEST); 
            }
        });
    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            imageView.setImageBitmap(photo);
        }  
    } 
}

This camera app gives you the option to re-view or re-take pictures, and when you select an image, you print it out to the activity.

Layout used in the above activities. Write buttons and image views.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/photo"></Button>
    <ImageView android:id="@+id/imageView1" android:layout_height="wrap_content" android:src="@drawable/icon" android:layout_width="wrap_content"></ImageView>

</LinearLayout>

In the Android manifest file,

<uses-feature android:name="android.hardware.camera"></uses-feature> 
<uses-feature android:name="android.hardware.camera" android:required="false"></uses-feature>

must be added.
