I think you should change the construction code of LayoutParams to:

LayoutParams ll = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ll.gravity = Gravity.TOP | Gravity.RIGHT;

In your code, you set the layout_width and layout_height value to MATCH_PARENT , so your ImageView will fill all your parent FrameLayout.

I think you need to provide height width in layout params. Because with match_parent it will take width and height of parent or you can use WRAP_CONTENT.

 mImageButton = new ImageButton(mContext);
LayoutParams ll = new LayoutParams(width,height);
ll.gravity = Gravity.RIGHT | Gravity.TOP;
mImageButton.setLayoutParams(ll);
mImageButton.setImageDrawable(getResources().getDrawable(R.drawable.ic_menu_moreoverflow_normal_holo_light));
this.addView(mImageButton);

I forgot to add Gravity.TOP. Main problem was that you were using MATCH_PARENT. Check now this should also work . You can give specific width and height to your image button as well that's why I mentiond width height. I have also metioned that you can use wrap content – Damanpreet Singh Feb 04 '16 at 06:31

Try this,

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

params.gravity = Gravity.TOP | Gravity.RIGHT;

mImageButton.setLayoutParams(params);
