如何向Android启动器添加自定义图标主题支持

Question

I am working on an android launcher, I want to add icon theme support to the launcher. The launcher uses launcher-2 source code . How to add theme support for Icons?

Answer 1

You have to traverse through the appfilter.xml file in icon pack and set drawable for the curresponding package name defined in the appfilter.xml file ... use XmlPullParser class to manipulate xml data....

here is a basic idea...

Resources resources = packageManager.getResourcesForApplication(packageName);
int xmlResId = resources.getIdentifier("appfilter", "xml", packageName);

if (xmlResId != 0) {
    XmlPullParser xpp = resources.getXml(xmlResId);
    // manipulate data using xpp
}

Some old icon packs has a different xml structure some has appfilter.xml in asset folder ...
