Launcher 快捷方式图标处理疑问

我想将Launcher上的快捷方式通过程序处理改成圆角的。

这里是处理图标的代码http://blog.csdn.net/Android_Tutor/archive/2010/11/02/5981753.aspx

我在Launcher.java的infoFromShortcutIntent方法中添加如下代码：



    Bitmap bitmap1 = ImageUtil.drawableToBitmap(context.getPackageManager().getDefaultActivityIcon());

    Bitmap zoomBitmap = ImageUtil.zoomBitmap(bitmap1, 60, 60);  

    icon = new BitmapDrawable(ImageUtil.getRoundedCornerBitmap(zoomBitmap, 10.0f));

完整的方法如下：



   private static ApplicationInfo infoFromShortcutIntent(Context context, Intent data) {

        Intent intent = data.getParcelableExtra(Intent.EXTRA_SHORTCUT_INTENT);

        String name = data.getStringExtra(Intent.EXTRA_SHORTCUT_NAME);

        Bitmap bitmap = data.getParcelableExtra(Intent.EXTRA_SHORTCUT_ICON);



        Drawable icon = null;

        boolean filtered = false;

        boolean customIcon = false;

        ShortcutIconResource iconResource = null;



        if (bitmap != null) {

           icon = new FastBitmapDrawable(Utilities.createBitmapThumbnail(bitmap, context));

           filtered = true;

           customIcon = true;

        } else {

            Parcelable extra = data.getParcelableExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE);

            if (extra != null && extra instanceof ShortcutIconResource) {

                try {

                    iconResource = (ShortcutIconResource) extra;

                    final PackageManager packageManager = context.getPackageManager();

                    Resources resources = packageManager.getResourcesForApplication(

                            iconResource.packageName);

                    final int id = resources.getIdentifier(iconResource.resourceName, null, null);

                    icon = resources.getDrawable(id);

                } catch (Exception e) {

                    w(LOG_TAG, "Could not load shortcut icon: " + extra);

                }

            }

        }



        if (icon == null) {

            icon = context.getPackageManager().getDefaultActivityIcon();

        }

        final ApplicationInfo info = new ApplicationInfo();

        //info.icon = icon;

        // modify start tang

        Bitmap bitmap1 = ImageUtil.drawableToBitmap(context.getPackageManager().getDefaultActivityIcon());

        Bitmap zoomBitmap = ImageUtil.zoomBitmap(bitmap1, 60, 60);  

        info.icon = new BitmapDrawable(ImageUtil.getRoundedCornerBitmap(zoomBitmap, 10.0f));

        // modify end tang

        

        info.filtered = filtered;

        info.title = name;

        info.intent = intent;

        info.customIcon = customIcon;

        info.iconResource = iconResource;



        return info;

    }
