试试这个：

protected void onActivityResult(int requestCode, int resultCode, Intent data)                                     
              {
    if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
        if (resultCode == RESULT_OK) {


             imageView = (ImageView) findViewById(R.id.imageView1);
            Bitmap photo = (Bitmap) data.getExtras().get("data");
            imageView.setImageBitmap(photo)
        }}}

当我拍照并在ImageView中传递时，照片浮动错误？
