                    case -1:
                        _data = data;
                        ShowImageInActivity();
                        break;
                }
            }

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, IMAGE_PICK);

No need to check if you want to pick only images then use above property. Same case with audio and video files, it automatically filters your required files.
