从我的应用程序使用 Intent 打开相机时停止保存图像

大家好，我通过这样的方式使用 Intent 打开相机，

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, ACTIVITY_CAMERA);

效果很好，并且给了我完美的结果，但是问题是这也会将图像保存到 SD 卡中，如何防止这种情况停止保存图像并仅将该数据使用到 onActivityResult() 方法

我不确定，但尝试一下。也许对你有帮助。

onActivityResult 我正在获取图像，然后将其存储到另一个位图中。

看这个：

if(resultCode == RESULT_OK && requestCode==TAKE_PHOTO_CODE){
         final File file = getTempFile(this);         
         try {           
             tempBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file));
             photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
             takePhotoFromCamera = true;
             // do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)         
        } catch (FileNotFoundException e) {           
            e.printStackTrace();         
        } catch (IOException e) {           
            e.printStackTrace();         
        } 
    }

现在，您可以在将文件放入位图后删除该文件。所以可能没有保存到SD卡上。

尝试一下。希望它能帮助你。

或者。。。

使用以下

代码获取用户拍摄的最后一张照片：

String[] projection = new String[]
{MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.DATA,
 MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
 DATE_TAKEN, MediaStore.Images.ImageColumns.MIME_TYPE};

final Cursor cursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                   projection, null, null, DATE_TAKEN + " DESC");

获取该图像后，将其删除。所以它会对你有帮助。

享受。 :))

I am not sure but try it. It might be help you.

onActivityResult i am taking the Image and then going to store it in to the another bitmap.

See this:

if(resultCode == RESULT_OK && requestCode==TAKE_PHOTO_CODE){
         final File file = getTempFile(this);         
         try {           
             tempBitmap = Media.getBitmap(getContentResolver(), Uri.fromFile(file));
             photoBitmap = Bitmap.createScaledBitmap(tempBitmap, display.getWidth(), display.getHeight(), true);
             takePhotoFromCamera = true;
             // do whatever you want with the bitmap (Resize, Rename, Add To Gallery, etc)         
        } catch (FileNotFoundException e) {           
            e.printStackTrace();         
        } catch (IOException e) {           
            e.printStackTrace();         
        } 
    }

Now, here you can delete the the file after taking it to the bitmap. So it might be not saved to the sdcard.

Try it. Hope it will help you.

or . . .

Use this:

code to get Last picture taken by user:

String[] projection = new String[]
{MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.DATA,
 MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
 DATE_TAKEN, MediaStore.Images.ImageColumns.MIME_TYPE};

final Cursor cursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                   projection, null, null, DATE_TAKEN + " DESC");

After getting that image, delete it. So it will help you.

Enjoy. :))
