Android method to determine if the interface you are currently on is home's main desktop

This article illustrates how Android can determine if the interface is home's main desktop. Share to everybody for everybody reference. Specific implementation methods are as follows:

/** 
*  Gets the name of the application package that belongs to the desktop application  
* @return  Returns 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) Since you want to judge the current interface, it is necessary to judge the first item in the current RunningTasks;

2) Introduce ActivityManager to obtain RunningTasks;

3) Take out PackageName of topActivity in RunningTasks;

4) Finally, compare with List obtained in step 1!

5) Relevant permissions shall be added

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

/** 
*  Determine if 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;
  }
}
