有人可以解释相机请求代码是什么？

我们为什么用它？

我正在尝试Android的练习,我看到了代码.

        imageView = (ImageView)this.findViewById(R.id.imageView1);
        image = (Button) findViewById(R.id.capture);

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


    }

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