imageView.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View view) { 
       selectImage(); 
      } 

     }); 
    } 

private void selectImage() { 
     final CharSequence[] items = {"Take Photo", "Choose from Library", 
       "Cancel"}; 
     AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this); 
     builder.setTitle("Add Photo!"); 
     builder.setItems(items, new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int item) { 
       if (items[item].equals("Take Photo")) { 
        activeTakePhoto(); 
       } else if (items[item].equals("Choose from Library")) { 
        activeGallery(); 
       } else if (items[item].equals("Cancel")) { 
        dialog.dismiss(); 
       } 
      } 
     }); 
     builder.show(); 
    } 


    private void activeTakePhoto() { //open camera 
     String filename = "Pic_" + System.currentTimeMillis() + ".jpg"; 
     Intent intent = new Intent("android.media.action.IMAGE_CAPTURE"); 
     File photo = new File(Environment.getExternalStorageDirectory(), filename); 
     intent.putExtra(MediaStore.EXTRA_OUTPUT, 
       Uri.fromFile(photo)); 
     imageUri = Uri.fromFile(photo); 
     startActivityForResult(intent, REQUEST_IMAGE_CAPTURE); 
    } 

    private void activeGallery() { // open gallery 
     Intent intent = new Intent(Intent.ACTION_PICK, 
       android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
     intent.setType("image/*"); 
     startActivityForResult(intent, RESULT_LOAD_IMAGE); 
    } 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     switch (requestCode) { 
      case RESULT_LOAD_IMAGE: 
       if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK & null != data) { 
        imageUri = data.getData(); 
        imageView.setImageURI(imageUri); 
       } 

       break; 

      case REQUEST_IMAGE_CAPTURE: 
       if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) { 
        try { 
         selectedImage = imageUri; 
         getContentResolver().notifyChange(selectedImage, null); 
         imageView.setImageURI(null); 
         imageView.setImageURI(imageUri); 
        } catch (Exception e) { 
         Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT) 
           .show(); 
        } 
       } 
     } 
    }
