下面分享具体Android 调用相机、打开相册、裁剪图片的实现代码,内容如下

private ImageView iv_user_photo;
  private String fileName = "";
  private File tempFile;
  private int crop = 300;// 裁剪大小
  private static final int OPEN_CAMERA_CODE = 10;
  private static final int OPEN_GALLERY_CODE = 11;
  private static final int CROP_PHOTO_CODE = 12;


  private OnClickListener PopupWindowItemOnClick = new OnClickListener() {

    @Override
    public void onClick(View v) {
      menuWindow.dismiss();
      switch (v.getId()) {
      // 拍照
      case R.id.btn_camera:
        initFile();
        openCamera();
        break;
      // 相册
      case R.id.btn_gallery:
        initFile();
        openGallery();
        break;
      default:
        break;
      }
    }
  };

  public void initFile() {
    if(fileName.equals("")) {
      if(FileUtil.existSDCard()) {
        String path = Environment.getExternalStorageDirectory() + File.separator + "JanuBookingOnline" + File.separator;
        FileUtil.mkdir(path);
        Logger.i("path:" + path);
        fileName = path + "user_head_photo.jpg";
        tempFile = new File(fileName);
      } else {
        CommonUitl.toast(context, "请插入SD卡");
      }
    }
  }

  /**
   * 调用相机
   */
  public void openCamera() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);// 打开相机
    intent.putExtra("output", Uri.fromFile(tempFile));
    startActivityForResult(intent, OPEN_CAMERA_CODE);
  }

  /**
   * 打开相册
   */
  public void openGallery() {
    Intent intent = new Intent(Intent.ACTION_PICK);// 打开相册
    intent.setDataAndType(MediaStore.Images.Media.INTERNAL_CONTENT_URI, "image/*");
    intent.putExtra("output", Uri.fromFile(tempFile));
    startActivityForResult(intent, OPEN_GALLERY_CODE);
  }

  /**
   * 裁剪图片
   * @param uri
   */
  public void cropPhoto(Uri uri) {
    Intent intent = new Intent("com.android.camera.action.CROP");
    intent.setDataAndType(uri, "image/*");
    intent.putExtra("output", Uri.fromFile(tempFile));
    intent.putExtra("crop", true);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    intent.putExtra("outputX", crop);
    intent.putExtra("outputY", crop);
    startActivityForResult(intent, CROP_PHOTO_CODE);
  }

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == 1)
      return;

    switch (requestCode) {
    case OPEN_CAMERA_CODE:
      cropPhoto(Uri.fromFile(tempFile));
      break;
    case OPEN_GALLERY_CODE:
      cropPhoto(data.getData());
      break;
    case CROP_PHOTO_CODE:
      try {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inSampleSize = 2;
        Bitmap bitmap = BitmapFactory.decodeFile(fileName, options);

        if (bitmap != null) {
          iv_user_photo.setImageBitmap(bitmap);
          CommonUitl.sharedPreferences(context, AppConstants.USER_PHOTO, fileName);
        }
      } catch (Exception e) {
        e.printStackTrace();
      }
      break;
    default:
      break;
    }

    super.onActivityResult(requestCode, resultCode, data);
  }
