我尝试在自定义启动器上安装图标包,我已阅读此说明How to install icon pack,但我无法理解如何使用该课程,此处&#39我做了什么:

IconPackManager ic = new IconPackManager();
HashMap<String, IconPackManager.IconPack> map = new HashMap<String, IconPackManager.IconPack>(ic.getAvailableIconPacks(false));
Iterator it = map.entrySet().iterator();
Drawable d = null;
String packName = null;
IconPackManager.IconPack packIcon = null;
    while (it.hasNext()) {
       Map.Entry pair = (Map.Entry)it.next();
       packName = (String)pair.getKey();
       packIcon = (IconPackManager.IconPack)pair.getValue();
       d = packIcon.getDrawableIconForPackage(packName, iconDrawable);
       setIcon(d);
    }

解决了这个问题:

String packName = null;
IconPackManager.IconPack packIcon = null;

IconPackManager ic = new IconPackManager();
HashMap<String, IconPackManager.IconPack> map = ic.getAvailableIconPacks(true);
Iterator it = map.entrySet().iterator();


        while (it.hasNext()) {
            Map.Entry pair = (Map.Entry)it.next();
            packName = (String)pair.getKey(); //Get icon pack name (app package)

            packIcon = (IconPackManager.IconPack)pair.getValue(); //Get icons

            if(packIcon.getDrawableIconForPackage("YourTargetPackageName", yourStandardIcon) != null) {

            //Your own method for set icon   
            setIcon(packIcon.getDrawableIconForPackage("YourTargetPackageName", yourStandardIcon));

            }else{
                //Your own method for set icon   
                setIcon(yourStandardIcon);
            }
        }

仅当安装了以下任何软件包时才能使用

1)是否已安装?

org.adw.launcher.THEMES
com.gau.go.launcherex.theme

getAvailableIconPacks应返回HashMap大小&gt; 0

2)下面是否返回有效drawable或null?

 d = packIcon.getDrawableIconForPackage(packName, iconDrawable);

在你的情况下使用是错误的。

您正在迭代抛出图标提供程序包名称。在以下情况下,您要求

d = packIcon.getDrawableIconForPackage(packName, iconDrawable);
//means 
//d = packIcon.getDrawableIconForPackage("org.adw.launcher.THEMES",conDrawable)

因此,如果没有google play的上述主题安装,则仅返回默认的drawable。
