GridView auto fit images

Question

im trying to get images displayed in a GridView and get the columns automatically set, so far I\'ve had to manually set the number of columns which is not what i want to do

Answer 1

A better solution is to measure the width programmatically, so you won't end up with a hard-coded column width:

Android: How does GridView auto_fit find the number of columns?

Answer 2

Experiment with the GridView attributes, specifically android:numColumns="auto_fit" and android:stretchMode. The following works for me:

<GridView 
    android:id="@+id/myGrid"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:padding="10dp"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:numColumns="auto_fit"
    android:columnWidth="60dp"
    android:stretchMode="columnWidth"    
    android:gravity="center"
/>

Answer 3

I'm not sure why someone voted down the answer above me (so I voted it up again): I had to solve a similar problem programatically (with a GridView of ImageView children). Some code removed for clarity:

    int iDisplayWidth = getResources().getDisplayMetrics().widthPixels ;

    iImageWidth = iDisplayWidth
        / iNumberOfColumns ; 
    gridview.setColumnWidth( iImageWidth );
    gridview.setStretchMode( GridView.NO_STRETCH ) ;    
    /* wrap_content in the xml file is supposed to do this, but it didn't seem to work */
