    private Button button_1;
    public int TAKE_PICTURE = 1;
    private ImageView image_view;
    private Bitmap bitmap;
    /** Called when the activity is first created. */
    @Override
       public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

         image_view = (ImageView) findViewById(R.id.result);
         button_1 = (Button) findViewById(R.id.button1);

        button_1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {

try this code::::

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        if (requestCode == REQUEST_CODE && resultCode == Activity.RESULT_OK)
            try {
            image_view.setImageUri(Uri.parse(data.getDataString()));
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
    }

Updated:::: Add the below permissions n manifeast file

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

Try this,

public class Camera extends Activity 
  {
 private static final int CAMERA_REQUEST = 1888;
 private String selectedImagePath;

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    Intent cameraIntent = new Intent(ACTION_IMAGE_CAPTURE);
    startActivityForResult(cameraIntent, CAMERA_REQUEST);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (resultCode == RESULT_OK) {
        if (requestCode == CAMERA_REQUEST) 
        { 
            Bitmap photo = (Bitmap) data.getExtras().get("data"); 
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            photo.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
            Random randomGenerator = new Random();randomGenerator.nextInt();
            String newimagename=randomGenerator.toString()+".jpg";
            File f = new File(Environment.getExternalStorageDirectory()
                                    + File.separator + newimagename);
            try {
                f.createNewFile();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            //write the bytes in file

            try {
                fo = new FileOutputStream(f.getAbsoluteFile());
            } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            try {
                fo.write(bytes.toByteArray());
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
                uri=f.getAbsolutePath(); 
    //this is the url that where you are saved the image
      }



  }

Try following code set. It works for me...

With in the onActivityResult method call following code set.

    Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);

    Matrix matrix = new Matrix();
    matrix.postRotate(90);

    int width = bitmap.getWidth();
    int height = bitmap.getHeight();

    Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);

    // Display the captured image oon your screen
    capturedImageView.setImageBitmap(resizedBitmap);

    getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    File pictureFile = getOutputMediaFile(MEDIA_TYPE_IMAGE);
    if (pictureFile == null){
        Log.d(TAG, "Error creating media file, check storage permissions: ");
        return;
    }

    try {
        FileOutputStream fos = new FileOutputStream(pictureFile);
        fos.write(data);
        fos.close();
    } catch (FileNotFoundException e) {
        Log.d(TAG, "File not found: " + e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, "Error accessing file: " + e.getMessage());
    }

Matrix part is not relevant to your problem directly. Then you will need following two methods also.

private static Uri getOutputMediaFileUri(int type){
      return Uri.fromFile(getOutputMediaFile(type));
}

private static File getOutputMediaFile(int type){

    File mediaStorageDir = new File(imagesSavingSubfolderPath);

    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    }

    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());

    if (type == MEDIA_TYPE_IMAGE){
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + "IMG_"+ timeStamp + ".jpg");
    } else {
        return null;
    }

    return mediaFile;
}   

Be careful with the variable name I have given. :-)

In the Manifest don't forget to give following permission too

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

if (requestCode == CAMERA) {
                    Log.d("log", " request code camera " + requestCode);
                    final File file = getTempFile(this);
                    try {
                        selImagePath = file.getAbsolutePath();
                        m_bmOCRBitmap = Media.getBitmap(getContentResolver(),
                                Uri.fromFile(file));
                        img_pht.setImageBitmap(m_bmOCRBitmap);
                        hideMenu();
                    } catch (FileNotFoundException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();

                    }
                } 


try this code...
