Android determines if the interface is now a home desktop method _android

The example in this article describes how Android can determine whether the interface is now a home desktop. Share to everyone for your reference. The implementation methods are as follows:

/** 
* Get the application package name that belongs to the desktop 
* @return return a list of strings containing all package names 
/private list<string> gethomes () { 
  list <String> names = new arraylist<string> (); 
  Packagemanager Packagemanager = This.getpackagemanager (); 
  Attribute 
  Intent Intent = new Intent (intent.action_main);
  Intent.addcategory (intent.category_home); 
  list<resolveinfo> Resolveinfo = packagemanager.queryintentactivities (Intent, 
    Packagemanager.match_ default_only); 
  for (Resolveinfo ri:resolveinfo) { 
   names.add (ri.activityInfo.packageName); 
   LOG.I ("Zhangyinfu Pinyinime.java", "PackageName =" + Ri.activityInfo.packageName);
  } 
  return names;
}

Analysis:

1 If you want to judge the current interface, it is necessary to judge the current Runningtasks first;

2) Introducing Activitymanager to obtain runningtasks;

3 Remove the PackageName of the topactivity in Runningtasks;

4 finally compared with the first step of the list to do!

5) need to add relevant permissions

Copy Code code as follows:

<uses-permission android:name= "Android.permission.GET_TASKS"/>

/** 
* To determine whether the current interface is desktop 
/public boolean ishome () { 
  Activitymanager Mactivitymanager = (Activitymanager) Getsystemservice (context.activity_service); 
  list<runningtaskinfo> RTI = mactivitymanager.getrunningtasks (1);
  List<string> STRs = Gethomes ();
  if (STRs!= null && strs.size () > 0) {return
   strs.contains (rti.get (0). Topactivity.getpackagename ());
  }else{return
   false;
  }
