How to retrieve the same original quality of image through Intent in onActivityResult()?

I have using a intent to fetch a image wise a gallery and camera.i got the image successful by startActivityForResult() but the image get in data fetch this data and get a image Url and set the Imageplaceholder but the image quality are very poor and image are blur.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
try {
bmp = getBitmapFromUri(selectedImage);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
image_view.setImageBitmap(bmp);
//to know about the selected image width and height
Toast.makeText(MainActivity.this, image_view.getDrawable().getIntrinsicWidth()+" & "+image_view.getDrawable().getIntrinsicHeight(), Toast.LENGTH_SHORT).show();
}
}

Place a 2D image on the top of the background

I am working on the android application with following requirements
Take images from gallery and display it as background.
This is done as follows:
btn_select.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"SelectPicture"),PICK_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == requestCode && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
imageView.setImageURI(Uri.parse(picturePath));
cursor.close();
}
2.Place a 2D iamge on the top of the background image.
3.Reposition the image by dragging
4.Scale the image.
Anyone please suggest the ways to complete steps 2,3 and 4.
Thanks in Advance!

Why I am unable to set ImageBitmap to RelativeLayout here?

I'm trying to select a background image from gallery and set it as Activity background. But the problem is here when I set RelativeLayout instead of ImageView, it gives me error on setImageBitmap, what;s the reason here? Here's my code: I referred to this tutorial : http://viralpatel.net/blogs/pick-image-from-galary-android-app/ Thanks in advance!
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.background);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}

That is because RelativeLayout doesn't have a method called setImageBitmap.
Referring to this link, you can use this to set it to your relative layout:
File f = new File(getRealPathFromURI(path));
Drawable d = Drawable.createFromPath(f.getAbsolutePath());
mRelativeLayout.setBackground(d);
private String getRealPathFromURI(Uri contentURI) {
Cursor cursor = getContentResolver().query(contentURI, null, null, null, null);
if (cursor == null) { // Source is Dropbox or other similar local file path
return contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
}

You can't do setImageBitmap on a RelativeLayout. I think what you want to do is setBackground which takes in a Drawable as parameter.

How to save a selected Uri pic to drawable?

I am trying to set the picture that the user chooses from their gallery, by using Uri, as their background for an app, but I cant quite figure it out. One thing that I tried doing was straight up setting the background to the uri, but it fails do to compatibility mismatch. How can I do this, either by programmatically setting the drawable or any other way at at all?
Here is what I have tried
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == 1) {
if (intent != null && resultCode == RESULT_OK) {
Uri selectedImage = intent.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
if (bmp != null && !bmp.isRecycled()) {
bmp = null;
}
bmp = BitmapFactory.decodeFile(filePath);
imageView.setBackground(selectedImage);//error here
//imageView.setBackgroundResource(0);//originally this, but this crashes also
imageView.setImageBitmap(bmp);
}
}
}

Check out this link Retrieve drawable resource from Uri
try {
InputStream inputStream = getContentResolver().openInputStream(yourUri);
yourDrawable = Drawable.createFromStream(inputStream, yourUri.toString() );
imageView.setImageDrawable(yourDrawable);
} catch (FileNotFoundException e) {
yourDrawable = getResources().getDrawable(R.drawable.default_image);
}

saving image picked from gallery for future use

Hey i have been looking for a while now. the following code picks the image from the android gallery and shows it in an imageView. but heres the thing, everytime the app is closed and restarted the has to be picked again. i would like to know how i can edit the following to save the image for good in the imageView.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}

The only thing that the user is picking is the path of the picture. So if you save the path to SharedPreferences, then everytime the app is started, you can use your existing code, but just change where you get the path:
String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", "");
if(!picturePath.equals(""))
{
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
EDIT:
This is a complete method you can use in OnCreate:
String picturePath = PreferenceManager.getDefaultSharedPreferences(this).getString("picturePath", "");
if(!picturePath.equals(""))
{
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
else {
selectImage();
}
In select image use your current code to start the picking activity, then in onActivityResult use this:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
PreferenceManager.getDefaultSharedPreferences(this).edit().putString("picturePath", picturePath).commit();
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.imgView);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
