Android image set height problems

Question

I'm developing an android app which requires an imageview (and textviews) to be updated on button click, but I want the image to match the height of four of my textviews. When I set the height of the imageview, it seems to keep the height of the previous update, not the current one. Here is my code to update the image and its height.

int nameHeight = t_name.getHeight();
int timeHeight = r_time.getHeight();
int dateHeight = r_date.getHeight();
int locaHeight = r_loca.getHeight();
int totalHeight = nameHeight + timeHeight + dateHeight + locaHeight;

i_img.getLayoutParams().height = totalHeight;

Bitmap image = getBitmapFromURL(event_image.get(eventToUse));
i_img.setImageBitmap(image);

触摸布局参数后，调用requestLayout()以使更改生效。
