            // TODO Auto-generated method stub
            Intent intent = new Intent();
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);

public void onActivityResult(int requestCode, int resultCode, Intent data){
    //Integer selectedImageUri;
    //Integer[] bg = {selectedImageUri};
    if (resultCode == RESULT_OK){
        if (requestCode == SELECT_PICTURE) {
            Uri selectedImageUri = data.getData();
                      ImageView img = (ImageView) findViewById(R.id.img);
            img.setImageURI(selectedImageUri);

So how to set that picture not as image for ImageView, but as RelativeLayout background

Answer 1

After picking the picture from gallery, you can set the picture like this-

    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK)
        {
            Uri imageUri = data.getData();
            Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);

            RelativeLayout relative = (RelativeLayout) findViewById(R.id.relative1);
            Drawable dr = new BitmapDrawable(bitmap);
            relative.setBackgroundDrawable(dr);
        }
    }

Answer 2

Try this :

<ImageView 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:scaleType="centerCrop"
        android:src="@drawable/background" />

Answer 3

If you are getting drawable resource then you can set background of relative layout using that drawable like the following.

  RelativeLayout relativeLayout;
  relativeLayout= (RelativeLayout) findViewById(R.id.layout1);
  RelativeLayout.setBackground(getResources().getDrawable(R.drawable.ic_launcher));

Hope it will help.
