이미지를 보내고 폴더에 저장하는 방법 user-android from

Question

먼저 사용자가 폴더를 만들고 이름을 지정할 수있는 주요 항목을 만들었습니다. 버튼을 누르면 그 다음 카메라로 이동합니다. 폴더가 생성되었지만 이미지가 경로에 저장 될 수 없습니다. 나는 완전히 혼란, 그리고 난 내 영어에 대해 사과

 final String direct = this.getIntent().getStringExtra("key"); 
public static final int MEDIA_TYPE_IMAGE = 1; 

/** Create a file Uri for saving an image or video */ 

Uri uriSavedImage=Uri.fromFile(new File(direct + "photo.jpg")); 

final Uri getOutputMediaFileUri(int type){ 
     return Uri.fromFile(getOutputMediaFile(type)); 
} 

/** Create a File for saving an image or video */ 
final File getOutputMediaFile(int type){ 
    // To be safe, you should check that the SDCard is mounted 
    // using Environment.getExternalStorageState() before doing this. 

    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
       Environment.DIRECTORY_PICTURES), "direct"); 
    // This location works best if you want the created images to be shared 
    // between applications and persist after your app has been uninstalled. 

    // Create the storage directory if it does not exist 
    if (! mediaStorageDir.exists()){ 
     if (! mediaStorageDir.mkdirs()){ 
      Log.d("MyCameraApp", "failed to create directory"); 
      return null; 
     } 
    } 

    // Create a media file name 
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date()); 
    File mediaFile; 

    if (type == MEDIA_TYPE_IMAGE){ 
     mediaFile = new File(mediaStorageDir.getPath() + File.separator + 
     "IMG_"+ timeStamp + ".jpg"); 
    } else { 
     return null; 
    } 

    return mediaFile; 
} 

}

I 활동 연장 그것이 효과가있을 것이라고 생각한다. 당신 :

final String direct = this.getIntent().getStringExtra("key"); 

Uri uriSavedImage = getOutputMediaFileUri(); 

final Uri getOutputMediaFileUri(){ 
    return Uri.fromFile(getOutputMediaFile()); 
} 

final File getOutputMediaFile(){ 
    // To be safe, you should check that the SDCard is mounted 
    // using Environment.getExternalStorageState() before doing this. 

    File mediaStorageDir = new File(Environment.getExternalStorageDirectory().getPath().toString(), direct); 
    // This location works best if you want the created images to be shared 
    // between applications and persist after your app has been uninstalled. 

    // Create the storage directory if it does not exist 
    if (! mediaStorageDir.exists()){ 
     if (! mediaStorageDir.mkdirs()){ 
      Log.d("MyCameraApp", "failed to create directory"); 
      return null; 
     } 
    } 

    File mediaFile = new File(mediaStorageDir.getPath() + "photo.jpg"); 

    return mediaFile; 
}

이 매니페스트 파일에 권한을 추가하는 것을 잊지 마세요 :

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 

@Override

      final String name = text.getText().toString(); 
      final String placeName = text2.getText().toString(); 
      final String dettaglio = text3.getText().toString(); 

      String place = placeName.substring(0, 3); 
      String direct = name + place + dettaglio; 

      Intent myIntent = new Intent(MainActivity.this, CameraView.class); 
      myIntent.putExtra("key", "/CameraTest/" direct + "/");
