如何在图库中的imageView上设置图像以及在Android中由相机拍摄的图像？

Question

In my app I want to set an image on a ImageView from gallery and I want to set an image which is taken by the camera. I have tried this code, when I load image from the gallery, it is working. But when I try to take a picture to set on ImageView , that activity is loaded but the image is not showing in the ImageView . Any solution for this? Here is my code:

First Activity

public class MainActivity extends ActionBarActivity {
    private static int RESULT_LOAD_IMAGE = 1;
    private static final int CAMERA_REQUEST = 1888;
    private ImageView imageView;
    Bitmap photo;
    String picturePath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
        buttonLoadImage.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {

                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, RESULT_LOAD_IMAGE);
            }
        });
        // this.imageView = (ImageView)this.findViewById(R.id.imgView);
        Button photoButton = (Button) this.findViewById(R.id.button2);
        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);

            }
        });

    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
