휴대 전화의 폴더를 만들고 이미지를 저장하는 방법

Question

휴대 전화 메모리에 새 폴더 "MyFolder"를 만들고 해당 폴더에 캡처 한 모든 이미지를 저장하는 방법은 무엇입니까? 도와주세요. 다음 코드는 모든 이미지를 Phone의 기본 이미지 갤러리에 저장합니다. 새 폴더를 만들고 해당 폴더에 캡처 한 모든 이미지를 저장하고 싶습니다. 나는 어떻게해야합니까? 이 도울 수 있다면

public class PhotoCaptureExample extends Activity 
    { 
protected Button _button; 
protected ImageView _image; 
protected TextView _field; 
protected String _path; 
protected boolean _taken; 

protected static final String PHOTO_TAKEN = "photo_taken"; 

@Override 
    public void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.main); 

    _image = (ImageView) findViewById(R.id.image); 
    _field = (TextView) findViewById(R.id.field); 
    _button = (Button) findViewById(R.id.button); 
    _button.setOnClickListener(new ButtonClickHandler()); 
    ; 
    _path = Environment.getExternalStorageDirectory() + "/myfolder 
/"+System.currentTimeMillis()+".jpg"; 




    File dir = new File(_path); 
    try{ 
     if(dir.mkdir()) { 
     System.out.println("Directory created"); 
     } 
     else { 
     System.out.println("Directory is not created"); 
     }} 
     catch(Exception e){ 

    } 



















} 

public class ButtonClickHandler implements View.OnClickListener 
{ 
    public void onClick(View view){ 
     Log.i("MakeMachine", "ButtonClickHandler.onClick()"); 
     startCameraActivity();

    Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 

    startActivityForResult(intent, 0); 
} 

@Override

    _taken = true; 

    BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inSampleSize = 4; 

    Bitmap bitmap = BitmapFactory.decodeFile(_path, options); 

    _image.setImageBitmap(bitmap); 

    _field.setVisibility(View.GONE); 
} 

@Override

    Log.i("MakeMachine", "onRestoreInstanceState()"); 
    if(savedInstanceState.getBoolean(PhotoCaptureExample.PHOTO_TAKEN)) { 
     onPhotoTaken(); 
    } 
} 

@Override 
protected void onSaveInstanceState(Bundle outState) { 
    outState.putBoolean(PhotoCaptureExample.PHOTO_TAKEN, _taken); 
} 
} 

Answer 1

당신은 폴더를 만들 매니페스트 파일에 다음과 같은 권한이 필요합니다.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.CAMERA" /> 
<uses-feature android:name="android.hardware.camera" />

감사합니다.

Answer 2

확인,

File mydir = context.getDir("mydir", Context.MODE_PRIVATE); //Creating an internal dir; 
File fileWithinMyDir = new File(mydir, "myfile"); //Getting a file within the dir. 
FileOutputStream out = new FileOutputStream(fileWithinMyDir); //Use the stream as usual to write into the file.

코드는 사용할 수 있지만이 디렉토리를 먼저 만들어야합니다.
