Android combining two LayoutParams

Question

I am attempting to fix both the Width and the margins of a ProgressBar with layout params

The following correctly sets the layout_margin

int finalHeight = soundcloudImage.getHeight() / 8;
int finalWidth = soundcloudImage.getWidth() / 4;

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();

progressParams.setMargins(0, 0, 0, finalHeight);

progressBar.setLayoutParams(progressParams);

And this successfully sets the Layout_Width

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(finalWidth*2, 20);

progressBar.setLayoutParams(params);

However I cannot seem to combine the statement to get them to work together

Here is the layout xml

<RelativeLayout
                android:id="@+id/relativelayout"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" >

                <ImageView
                    android:id="@+id/imageView"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:src="@drawable/soundcloudimage" />

                <TextView
                    android:id="@+id/myImageViewText"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_alignBottom="@+id/imageView"
                    android:textSize="20dp"
                    android:layout_centerHorizontal="true"
                    android:text=""
                    android:textColor="#EA4F17" />

                <ProgressBar
                    android:id="@+id/progressBar"
                    style="?android:attr/progressBarStyleHorizontal"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignBottom="@+id/imageView"
                    android:layout_alignLeft="@+id/imageView"
                    android:layout_alignParentRight="true" />

            </RelativeLayout>

Any help would be great

EDIT: attempted the following

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();
progressParams.width=finalWidth*2;
progressParams.height= 20;
progressParams.setMargins(0, 0, 0, finalHeight);

progressBar.setLayoutParams(progressParams);

and it results in this

EDIT: Also tried this:

RelativeLayout.LayoutParams progressParams = new RelativeLayout.LayoutParams(finalWidth*2, 20);
progressParams.setMargins(0, 0, 0, finalHeight);    
progressBar.setLayoutParams(progressParams);

which creates this

Answer 1

RelativeLayout.LayoutParams progressParams = (RelativeLayout.LayoutParams)progressBar.getLayoutParams();
progressParams.width=finalWidth*2;
progressParams.height= 20;
progressParams.setMargins(finalWidth, 0, finalWidth, finalHeight);

progressBar.setLayoutParams(progressParams);

EDIT

Try this:

RelativeLayout.LayoutParams progressParams = new RelativeLayout.LayoutParams(finalWidth*2, 20);
progressParams.setMargins(0, 0, 0, finalHeight);    
progressBar.setLayoutParams(progressParams);
