That is not really possible. For example, if you have a million cells, the user's device is not going to stretch to a few hundred meters just to please you. > However, I am seeing only > one row when set (layout_width=MATCH_PARENT and) > layout_height=WRAP_CONTENT. wrap_content is not a valid value for vertically scrollable widgets, particularly ListView and GridView. Please use fill_parent/match_parent, optionally along with other layout rules to control the size (e.g., layout_weight for LinearLayout). > Looking at onMeasure in > http://www.netmite.com/android/mydroid/frameworks/base/core/java/android/widget/GridView.java, That is not a valid source URL for current versions of Android AFAIK. Use Google Code Search or http://source.android.com, though the latter may still be down due to the kernel.org hack from earlier in the week. > I see that onMeasure does not calculate the number of rows at all, and > so I can understand why only one row shows up.

No. Please use fill_parent/match_parent, optionally along with other layout rules to control the size (e.g., layout_weight for LinearLayout). -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android 3.1 Programming Books: http://commonsware.com/books -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
