Android GridView stretchMode with Async ImageView Loading -


i have following gridview defined w/stretchmode set "columnwidth".

<gridview android:id="@+id/grid"     android:layout_width="fill_parent"      android:layout_height="wrap_content"     android:columnwidth="160dp"     android:numcolumns="auto_fit"     android:verticalspacing="10dp"     android:horizontalspacing="10dp"     android:stretchmode="columnwidth"     android:listselector="@drawable/list_selector" />

each item in gridview structured follows.

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="match_parent"      android:layout_height="wrap_content"     android:padding="2dp" >     <framelayout         android:layout_width="match_parent"          android:layout_height="wrap_content"     >         <imageview android:id="@+id/videogriditemimage"             android:layout_width="match_parent"              android:layout_height="wrap_content"             android:adjustviewbounds="true"         />         <textview android:id="@+id/videogriditemduration"             android:layout_width="wrap_content"               android:layout_height="wrap_content"                 android:layout_gravity="bottom"                 android:background="#88000000"             android:textcolor="#f1f1f1"             android:textappearance="@android:style/textappearance.small"             android:padding="2dp"         />     </framelayout>     <textview android:id="@+id/videogriditemtitle"          android:layout_width="match_parent"          android:layout_height="wrap_content"         android:gravity="left"         android:textappearance="@android:style/textappearance.medium"         android:textcolor="#f1f1f1"         android:maxlines="1"         android:background="#88000000"         android:paddingleft="2dp"         android:paddingright="2dp"     />     <textview android:id="@+id/videogriditemsubtitle"          android:layout_width="match_parent"          android:layout_height="wrap_content"         android:gravity="left"         android:textstyle="italic"         android:textcolor="#666"         android:textappearance="@android:style/textappearance.small"          android:maxlines="1"         android:background="#88000000"         android:paddingleft="2dp"         android:paddingright="2dp"     /> </linearlayout>

in gridview's adapter, i'm async loading , displaying images passing url , reference of imageview dedicated class. class downloads image bitmap , updates imageview using setimagebitmap(). workflow functions expected; however, images aren't filling entire width of imageview. there's small amount of paddding on left/right sides. realize can use scaletype="fitxy", isn't ideal skews images. setting src attribute of imageview local image scales fine stretchmode="columnwidth". guess imageview scaling original columnwidth , not stretched/dynamic width. have insight why occurring and/or how fix? in advance help.

you have 2 options:

  1. set imageview's layout_width wrap_content. imageview resize based on size of image , column adjust accordingly.

  2. set imageview's scaletype centercrop. try fit image imageview without skewing , cut off excess doesn't fit. leave no blank space.
