Change Image view height and width programmatically based on drawable images

I want to change the Imageview Height and width based on the drawable image size programmatically? i have two types of images one is horizontal and another one is vertical. By default i have write my xml code for vertical images but i want to change Image view height and width for horizontal images by java code. how to do this ?

my xml code is 

<RelativeLayout
    android:paddingTop="47dp"
    android:paddingBottom="48dp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"
    android:id="@+id/flipcardWrapper">

    <ImageView
        android:orientation="horizontal"
        android:layout_width="365dp"
        android:layout_height="match_parent"
        android:layout_centerInParent="true"
        android:layout_centerVertical="true"
        android:id="@+id/imgtrans"
        android:background="@android:color/transparent" />

and my java code to change height and width of image view is 

imgview = (ImageView) findViewById(R.id.imgtrans);
    Drawable d = getResources().getDrawable(R.drawable.image1);
    int h = d.getIntrinsicHeight();
    int w = d.getIntrinsicWidth();



    if(d.getIntrinsicHeight()==797 && d.getIntrinsicWidth()==1218)
    {
        imgtrans.getLayoutParams().width=300;
        imgtrans.requestLayout();

    }

Use ViewGroup.LayoutParams.MATCH_PARENT in java code.

imgview = (ImageView) findViewById(R.id.imgtrans);
Drawable d = getResources().getDrawable(R.drawable.image1);
int h = d.getIntrinsicHeight();
int w = d.getIntrinsicWidth();



if(d.getIntrinsicHeight()==797 && d.getIntrinsicWidth()==1218)
{
    imgtrans.getLayoutParams().width = ViewGroup.LayoutParams.MATCH_PARENT;
    imgtrans.getLayoutParams().height = someValue;
    imgtrans.requestLayout();
}

Set two images for horizontal and another one is vertical in drawable .then find screen orientation based on it set image

if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){
 Drawable d = getResources().getDrawable(R.drawable.imagehorizontal);
//set your other properties
}

if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){
 Drawable d = getResources().getDrawable(R.drawable.imagevertical);
//set your other properties
}
