Extract GridView in only one row?

Is there a way to force a gridview to be only one row? Currently, by default, it will increase its height to accommodate all the views provided by its adapter.

You must combine horizontal SCROLLVIEW and LINEARLAYOUT and GRIDVIEW to achieve what you want! place the grid in linearlayout and place the linear layout in the horizontal scroll view;

then when setting up the adapter! count the amount of data! after that you must calculate the desired width to show all your items! For example, you want to show 8 items! each width is 100dp. so the desired width will be 800dp! then you should add these lines of code

yourGridView.setNumColumns(8);
LinearLayout.LayoutParams lp=new LinearLayout.LayoutParams(800, ViewGroup.LayoutParams.MATCH_PARENT);
yourGridView.setLayoutParams(lp);

dnt forget to set the width of the linear layout as WRAP_CONTENT in xml!

*** IMPORTANT NOTE

as I know, having done this, gridview cannot collect garbage, because Scroll View does not support such a thing, and your mesh view is embedded in it! therefore dnt use this method for a large number of images or you will get a HEAP SIZE error!
