android相机默认存储路径,如何将相机照片保存到我的Android应用程序中的相册文件夹...

上午是Android新手。我要创建一个Android应用程序。我想在我的应用程序中创建一个相册文件夹，并将相机照片保存到相册文件夹中。请告诉我如何。如何将相机照片保存到我的Android应用程序中的相册文件夹

我的代码是：

公共类CameraPhotoCapture延伸活动{

final static int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 1;

Uri imageUri = null;

static TextView imageDetails = null;

public static ImageView showImg = null;

CameraPhotoCapture CameraActivity = null;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_camera_photo_capture);

CameraActivity = this;

imageDetails = (TextView) findViewById(R.id.imageDetails);

showImg = (ImageView) findViewById(R.id.showImg);

final Button photo = (Button) findViewById(R.id.photo);

photo.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

/***** Define the file-name to save photo taken by Camera activity *******/

String fileName = "Camera_Example.jpg";

// Create parameters for Intent with filename

ContentValues values = new ContentValues();

values.put(MediaStore.Images.Media.TITLE, fileName);

values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");

/****** imageUri is the current activity attribute, define and save it for later usage *****/

imageUri = getContentResolver().insert(

MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

/****** EXTERNAL_CONTENT_URI : style URI for the "primary" external storage volume. ******/

/****** Standard Intent action that can be sent to have the camera application capture an image and return it. ******/

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);

intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

}

});

}

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data)

{

if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {

if (resultCode == RESULT_OK) {

String imageId = convertImageUriToFile(imageUri,CameraActivity);

new LoadImagesFromSDCard().execute(""+imageId);

} else if (resultCode == RESULT_CANCELED) {

Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();

} else {

Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show();

}

}

}

int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);

int columnIndexThumb = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);

int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

//int orientation_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.ORIENTATION);

int size = cursor.getCount();

/******* If size is 0, there are no images on the SD Card. *****/

if (size == 0) {

imageDetails.setText("No Image");

}

else

{

int thumbID = 0;

if (cursor.moveToFirst()) {

/**************** Captured image details ************/

/***** Used to show image on view in LoadImagesFromSDCard class ******/

imageID = cursor.getInt(columnIndex);

thumbID = cursor.getInt(columnIndexThumb);

String Path = cursor.getString(file_ColumnIndex);

//String orientation = cursor.getString(orientation_ColumnIndex);

}

}

问题不明确。你有创建文件夹的问题吗？或者将照片保存/复制到它？如果是这样，那么请分享代码。 –
