我正在尝试拍摄照片并将其保存在SD卡中。生成了图像uri,当我调用startActivityForResult时,它返回而不调用onActivityResult。

  private Uri dispatchTakePictureIntent() {
      Uri uri = null;
      Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
      // Ensure that there's a camera activity to handle the intent
      if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
          // Create the File where the photo should go
          File photoFile = null;
          try {
              photoFile = createImageFile();
              Log.d("dispatchTakePictureIntent", "inside try");
          } catch (IOException ex) {
              // Error occurred while creating the File
              Log.d("dispatchTakePictureIntent", "inside catch");

          }
          // Continue only if the File was successfully created
          if (photoFile != null) {

              Log.d("dispatchTakePictureIntent", "inside secondif");
              takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                      Uri.fromFile(photoFile));
              Log.d("dispatchTakePictureIntent","after putExtra");

              startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
              uri = Uri.fromFile(photoFile);
              Log.d("dispatchTakePictureIntent", uri.toString());
              return uri;
          }

      }
      return uri;
  }


  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      Log.d("onActivityResult", "outside if");
      ImageView recipeImageView = (ImageView)this.findViewById(R.id.dishImage);
      Log.d("onActivityResult", "outside if");
      Log.d("requestcode", requestCode+"");
      Log.d("REQUEST_IMAGE_CAPTURE", REQUEST_IMAGE_CAPTURE+"");
      Log.d("resultcode", resultCode+"");
      Log.d("REESULT_OK", RESULT_OK+"");
      Log.d("onActivityResult", "inside if");
      if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
          Log.d("onActivityResult", "inside if");
          Bundle extras = data.getExtras();
          Bitmap imageBitmap = (Bitmap) extras.get("data");
          recipeImageView.setImageBitmap(imageBitmap);
      }
      Log.d("onActivityResult", "completed if");
  }


String mCurrentPhotoPath;

  private File createImageFile() throws IOException {
      // Create an image file name
      String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
      String imageFileName = "JPEG_" + timeStamp + "_";
      File storageDir = Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES);
      Log.d("createImageFile", Environment.DIRECTORY_PICTURES);
      Log.d("createImageFile", storageDir.toString());
      Log.d("createImageFile", imageFileName);
      File image = File.createTempFile(
          imageFileName,  /* prefix */
          ".jpg",         /* suffix */
          this.getCacheDir()     /* directory */
          //storageDir
      );
      Log.d("createImageFile", image.toString());
      // Save a file: path for use with ACTION_VIEW intents
      mCurrentPhotoPath = "file:" + image.getAbsolutePath();
      Log.d("createImageFile", mCurrentPhotoPath);
      return image;
  }

然而,当我只是调用缩略图而不将其保存在SD卡中时,会调用onActivityResult并显示缩略图

 private void dispatchTakePictureIntentThumb() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }

当我查看日志消息时。

通过其他帖子,我确保一切顺利。

  1. 启用写入权限。
  2. <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
                     android:maxSdkVersion="18" />
    
    1. 我调用了startActivityForResult()而不是startActivity()
    2. android:launchMode =“singleInstance”,清单中没有android:noHistory =“true”
    3. 在功能方面,能够打开相机并拍照,但是当我们尝试保存时,它仍处于相同的状态。

我遇到过这个问题。 你在活动的属性中使用android:launchMode =“singleInstance”吗?

答案 1 :(得分:0)

以下是将图像保存在外部目录中的功能

public static String saveImageInExternalCacheDir(Context context, Bitmap bitmap, String myfileName) {
    String fileName = myfileName.replace(' ', '_') + getCurrentDate().toString().replace(' ', '_').replace(":", "_");
    String filePath = (context.getExternalCacheDir()).toString() + "/" + fileName + ".jpg";
    try {
        FileOutputStream fos = new FileOutputStream(new File(filePath));
        bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fos);
        fos.flush();
        fos.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return filePath;
}
