java - prevent gridView from expanding to fit landscape width -


i have gridview 4 columns of imgs. when phone turned landscape layout, grids of gridview expand fill width, creating white spaces in between img although img stay @ desired width. there way keep grid view filling width of screen when in landscape layout ?

i have 2 methods that:

1) create layout each orientation:

res/layout/.... res/layout-land/.... 

2) 1 layout both vertical , horizontal orientation:

  • set gridview with: android:numcolumns="4"

  • your custom view item, set android:layout_width="match_parent"

with second method, may encount problem high of item. create custom view , override onmeasure.

for example: need linearlayout item , keep ratio height/width = 4.5/4, following custom:

public class mylinearlayout extends linearlayout {     //..... constructor methods     @override     protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {         int scaleheight =(int)( widthmeasurespec/4*4.5);         super.onmeasure(widthmeasurespec, scaleheight);     } }
