Centering The Matrix Of Imageviews To The Center Of The Screen Dynamically

This is my Layout File: RelativeLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:tools='http://schemas.android.com/tools' android:id='@+id/image

Solution 1:

As I said you could wrap the image matrix in another RelativeLayout and center that in in the initial RelativeLayout:

RelativeLayoutre= (RelativeLayout)findViewById(R.id.imageLayout);
RelativeLayoutcontent=newRelativeLayout(this);
RelativeLayout.LayoutParamsclp=newRelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        clp.addRule(RelativeLayout.CENTER_IN_PARENT);
        content.setLayoutParams(clp);
for (inti=0; i < rows; i++) {
   for (intj=0; j < cols; j++) {
       // ...the current loop...
       img.setLayoutParams(rlp);            
       content.addView(img);
   } 
}
re.addView(content);

Also remove the android:gravity and the android:layout_gravity properties from the xml RelativeLayout.
