图片显示不出来图库 [英] Photo does not show up to gallery

问题描述

我试图把使用Android相机中的照片，并告诉它保存到手机的画廊。我想我搞砸的道路上，但我似乎无法找到我的错误。有人能帮助我吗？我非常新手在机器人。

code调用相机

 意图cameraIntent =新的意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
                  字符串uriToFileInExternalStorage = NULL;
                    cameraIntent.putExtra（MediaStore.EXTRA_OUTPUT，uriToFileInExternalStorage）;
                    startActivityForResult（cameraIntent，CAMERA_PIC_REQUEST）;
 

code处理的照片，并告诉它去画廊。

 保护无效onActivityResult（INT申请code，INT结果code，意图数据）{
            如果（要求code == CAMERA_PIC_REQUEST）{
                //检查相机拍摄的照片通过检查请求code

                Toast.makeText（MainActivity.this，照片捕捉，Toast.LENGTH_SHORT）.show（）;


                开放的我们的mpath = data.getData（）;
                 意图mediaScanIntent =新的意图（Intent.ACTION_MEDIA_SCANNER_SCAN_FILE）;

                    mediaScanIntent.setData（的mpath）;
                    this.sendBroadcast（mediaScanIntent）;

            }
        }
 

解决方案

在这里尝试给出code：的添加照片至图库

 意图mediaScanIntent =新的意图（Intent.ACTION_MEDIA_SCANNER_SCAN_FILE）;
文件F =新的文件（mCurrentPhotoPath）;
乌里contentUri = Uri.fromFile（F）;
mediaScanIntent.setData（contentUri）;
this.sendBroadcast（mediaScanIntent）;
 

我建议您下载的例子 PhotoIntentActivity 阅读和理解如何取 mCurrentPhotoPath 值。

I'm trying to take a photo using the android camera and telling it to save to the phone's gallery. I think i messed up on the path, but i can't seem to find my error. Could someone help me? I'm very novice at android.

Code to call camera

   Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                  String uriToFileInExternalStorage = null;
                    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriToFileInExternalStorage);
                    startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

code to handle photo and tell it to go to gallery.

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (requestCode == CAMERA_PIC_REQUEST) {
                //check if camera has taken picture by checking request code

                Toast.makeText(MainActivity.this, "Photo Captured", Toast.LENGTH_SHORT).show();


                Uri mPath=data.getData();
                 Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);

                    mediaScanIntent.setData(mPath);
                    this.sendBroadcast(mediaScanIntent);

            }
        }

解决方案

Try code given here: Add the Photo to a Gallery

Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(mCurrentPhotoPath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);

I would suggest you to download example PhotoIntentActivity to read and understand how to fetch mCurrentPhotoPath value.
