Android : How to Capture Image in Fragment Android

I am working with capturing an image and then show it on my IMageView in my fragment. I searched this through web and still I cannot make it. Below is what I am doing.

btnCaptureImg.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
        startActivityForResult(cameraIntent, 1888); 
    }
});

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1888 && resultCode == Activity.RESULT_OK) {  
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        imageView.setImageBitmap(photo);
    }

    super.onActivityResult(requestCode, resultCode, data);
}
