//获取当前的Activity名称 package.classname

private String getTopActivity(Activity context){

 ActivityManager am= (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

      List<RunningTaskInfo> runningTasks = am.getRunningTasks(1);

      RunningTaskInfo rti = runningTasks.get(0);

      ComponentName cn = rti.topActivity;

      Log.v("offline",  "getClassName = " + cn.getClassName());//包名+类名

      Log.v("offline",  "getShortClassName = " + cn.getShortClassName());//类名

      Log.v("offline",  "getPackageName = " + cn.getPackageName());//包名

}

少不了权限:

  <!-- 获取activity名称 -->

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