Set the GridView subkey to a wide-height consideration of the screen fit

/**
 * Get screen Width */public
static int getscreenwidth (context context) {
    WindowManager manager = ( WindowManager) Context
            . Getsystemservice (context.window_service);
    Display display = Manager.getdefaultdisplay ();
    return Display.getwidth ();
}

public static int Diptopx (context context, int dip) {
    if (density <= 0.0F) {
        density = context.getresources (). g Etdisplaymetrics (). density;
    }

    return (int) (float) dip * density + 0.5F);
}

Screen fit for the GridView subkey, child item width, height and width

Itemwidth = (Getscreenwidth (this)-(3*DIPTOPX (this, 3))/2;

To set the parameters of a subkey in the GetView in the adapter of the GridView

Public View GetView (int position, View Convertview, ViewGroup parent) {
    Viewhodler viewhodler;
    String url = blogalbumlist.get (position). Getalbumurl ();
    if (Convertview = = null) {
        Convertview = view.inflate (context, r.layout.celebrity_item, null);
        Viewhodler = new Viewhodler ();
        Viewhodler.iv_image = (ImageView) Convertview.findviewbyid (r.id.iv_image);
        Convertview.settag (Viewhodler);
    } else {
        Viewhodler = (viewhodler) convertview.gettag ();
    }
    if (ViewHodler.iv_image.getTag ()!=url | | ViewHodler.iv_image.getTag () ==null) {
    imagetools.getimageloader (). DisplayImage (Blogalbumlist.get (position) . Getalbumurl (), Viewhodler.iv_image, mdisplayimageoptions);
    ViewHodler.iv_image.setTag (URL);
    }
    abslistview.layoutparams param = new Abslistview.layoutparams (Leoapplication.itemwidth, Leoapplication.itemwidth);
    Convertview.setlayoutparams (param);
    return convertview;
}

In fact, the GridView has an attribute. android:stretchmode= "columnWidth"//Zoom and column width size sync

Some special properties of the GridView:

1.android:numcolumns= the number of columns in the "Auto_fit"//gridview is set to Automatic

2.android:columnwidth= "90DP"//The width of each column, which is the width of the item

3.android:stretchmode= "columnWidth"//Zoom sync with column width size

4.android:verticalspacing= "10DP"//two margins between lines

5.android:horizontalspacing= the margin between the "10DP"//Two columns

6.android:cachecolorhint= "#00000000"//Remove the default black background when dragging

7.android:listselector= "#00000000"//Remove yellow background When selected

8.android:scrollbars= ' None '//Hide the GridView scroll bar

9.android:fadescrollbars= "true"//set to True to enable automatic hiding and display of scroll bars

10.android:fastscrollenabled= ' true '//gridview a fast-scrolling button (at least 4 pages are not displayed)

11.android:fadingedge= "None"//gridview fading (Fade) edge color is NULL, the default value is vertical. (can be interpreted as a hint color for the top and bottom edges)

12.android:fadingedgelength= "10dip"//Definition of fading (fade) edge length

13.android:stackfrombottom= "true"//set to True, the list that you do well will display the bottom of your list

14.android:transcriptmode= "Alwaysscroll"///When you add data dynamically, the list will automatically scroll down the latest entries can automatically scroll to the visual range
