推荐答案

你好，你可以尝试这个code，它为我工作正常。

Hello you can try out this code, it works fine for me.

private String getAppName(int pID)
{
    String processName = "";
    ActivityManager am = (ActivityManager)this.getSystemService(ACTIVITY_SERVICE);
    List l = am.getRunningAppProcesses();
    Iterator i = l.iterator();
    PackageManager pm = this.getPackageManager();
    while(i.hasNext()) 
    {
          ActivityManager.RunningAppProcessInfo info = (ActivityManager.RunningAppProcessInfo)(i.next());
          try 
          { 
              if(info.pid == pID)
              {
                  CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(info.processName, PackageManager.GET_META_DATA));
                  //Log.d("Process", "Id: "+ info.pid +" ProcessName: "+ info.processName +"  Label: "+c.toString());
                  //processName = c.toString();
                  processName = info.processName;
              }
          }
          catch(Exception e) 
          {
                //Log.d("Process", "Error>> :"+ e.toString());
          }
   }
    return processName;
}
