Gridview gridline settings

Today, I want to use grid layout to display products in online shopping malls, but I always feel that it is not easy to use it, so I want to add a gridline to it, but I have encountered a problem, grid layout is actually very simple. It is to set the background color of the gridview layout and the layout referenced by the adapter to set the background color. My settings are as follows:

1 2 3 4 5 6 7 8 9

<GridView android:id="@+id/gv_group" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#DCDCDC" android:horizontalSpacing="1dp" android:numColumns="2" android:stretchMode="columnWidth" android:verticalSpacing="1dp" />

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92

<? XML version = "1.0" encoding = "UTF-8"?> <Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: Background = "@ Android: color/White" Android: padding = "3dp"> <relativelayout Android: Id = "@ + ID/rl_group" Android: layout_width = "match_parent" Android: layout_height = "wrap_content" Android: orientation = "vertical"> <imageview Android: Id = "@ + ID/iv_group_image" Android: layout_width = "160dp" Android: layout_height = "90dp" Android: layout_centerhorizontal = "true" Android: contentdescription = "@ string/no" Android: scaletype = "fitxy"/> <textview Android: Id = "@ + ID/TV _group_desp" Android: layout_width = "160dp" Android: layout_height = "wrap_content" Android: layout_alignleft = "@ ID/iv_group_image" Android: layout_below = "@ ID/iv_group_image" Android: layout_margintop = "2dp" Android: ellipsize = "end" Android: gravity = "center_vertical" Android: lines = "2" Android: TEXT = "Haier 1.5 fluorine-free air conditioner with Variable Frequency wall-mounted air conditioner" Android: textsize = "14sp"/> <linearlayout Android: Id = "@ + ID/ll_price" Android: layout_width = "160dp" Android: layout_height = "wrap_content" Android: layout_alignleft = "@ ID/TV _group_desp" Android: layout_below = "@ ID/TV _group_desp" Android: layout_margintop = "3dp" Android: Orientation = "horizontal"> <textview Android: Id = "@ + ID/TV _group_price" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: text = "32 32" Android: textcolor = "@ color/red" Android: textsize = "16sp"/> <textview Android: id = "@ + ID/TV _group_delete" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: layout_marginleft = "8dp" Android: text = "21 21" Android: textcolor = "@ Android: color/darker_gray" Android: textsize = "12sp"/> </linearlayout> <linearlayout Android: layout_width = "160dp" Android: layout_height = "wrap_content" Android: layout_alignleft = "@ ID/ll_price" Android: layout_below = "@ ID/ll_price" Android: Orientation = "horizontal"> <textview Android: id = "@ + ID/TV _group_discount" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: ellipsize = "end" Android: singleline = "true" Android: TEXT = "2.0 off" Android: textcolor = "# ffff2e2e" Android: textsize = "12sp"/> <textview Android: Id = "@ + ID/TV _group_detail" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: layout_marginleft = "8dp" Android: ellipsize = "end" Android: singleline = "true" Android: TEXT = "0 items purchased" Android: textcolor = "@ Android: color/darker_gray" Android: textsize = "12sp"/> </linearlayout> </relativelayout> </linearlayout>

The result is as follows:

I circled the four sides. What do you think is ugly? Anyway, I think it is ugly, this can be tangled, and finally find a solution, so easy... is to add such an attribute in the gridview layout:

Android: listselector = "@ null"

The display effect is as follows:

How is it? Is it awesome?
