How to change the shape of an uploaded image (Image from photo gallery) into circular form

Question

How to change the shape of an uploaded image (Image from photo gallery) into circular form in android eclipse.

Answer 1

This is how you use it :

//this the button which allows you to access the gallery
pic.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            gallery();
        }
    });

//this allows you select one image from gallery
 public void gallery() {
    intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), 1);
}
//when you start activity for result and choose an image, the code will automatically continue here
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == RESULT_OK) {
        if (requestCode == 1) {
            Uri current_ImageURI = data.getData();
            selectedImagePath = getPath(current_ImageURI);
            image.setImageDrawable(RoundedBitmapDrawableFactory.create(getResources(),selectedImagePath));
        } 
    }
}

public String getPath(Uri contentUri) {
// we have to check for sdk version because from lollipop the retrieval of path is different 
        if (Build.VERSION.SDK_INT < 21) {
            // can post image
            String[] proj = {MediaStore.Images.Media.DATA};
            Cursor cursor = getActivity().getApplicationContext().getContentResolver().query(contentUri, proj, null, null, null);
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();

            return cursor.getString(column_index);
        } else {
            String filePath = "";
            String wholeID = DocumentsContract.getDocumentId(contentUri);

            // Split at colon, use second item in the array
            String id = wholeID.split(":")[1];

            String[] column = {MediaStore.Images.Media.DATA};

            // where id is equal to
            String sel = MediaStore.Images.Media._ID + "=?";

            Cursor cursor = getActivity().getContentResolver().
                    query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                            column, sel, new String[]{id}, null);


            int columnIndex = cursor.getColumnIndex(column[0]);

            if (cursor.moveToFirst()) {
                filePath = cursor.getString(columnIndex);
            }
            cursor.close();
            return filePath;
        }
    }

Now the two functions below : decode the sample size of the bitmap (to do correct scaling) and the other extracts the bitmap from the path are also no longer to be used

The Circular Bitmap class is no longer to be used
