以下是我省去首尾后代碼的主要部分。我想實(shí)現(xiàn)的功能就是顯示后臺(tái)運(yùn)行程序的名稱。protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); public static HashSet<String> getRunningApps(Context context) { final HashSet<String> hashSet = new HashSet<String>(); final ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); final PackageManager packageManager = context.getPackageManager(); List<RunningTaskInfo> runningTasks = activityManager.getRunningTasks(Integer.MAX_VALUE); for (RunningTaskInfo runningTaskInfo : runningTasks) { String packageName = runningTaskInfo.baseActivity.getPackageName(); try { String appName = packageManager.getApplicationInfo(packageName, 0).loadLabel(packageManager).toString(); hashSet.add(appName); } catch (NameNotFoundException exception) { // handle Exception } } return; }}然后在eclipse上顯示“ public static HashSet<String> getRunningApps(Context context) { ” 這一行有錯(cuò)，錯(cuò)誤為：Multiple markers at this line - Syntax error on token "(", ; expected - Illegal modifier for parameter getRunningApps; only final is permitted - Syntax error on token ")", ; expected誰(shuí)能教教我怎么改？尤其是說(shuō)“不用（）應(yīng)該用；”的怎么改??？
