如何在我的應用程序中獲取正在運行的線程

Question

我正在嘗試獲取應用程序中的所有活動/正在運行的線程。我寫了下面的發佈代碼，並且得到了下面的發佈結果。 事實上，沒有在貼輸出線程屬於我的應用程序，除了

07-10 15:36:48.621 19333-19624/eu.men.m2sapp D/GcmIntentService: thread.toString():Thread[IntentService[GcmIntentService],5,main] 

1）是什麼數字5表示？

2）似乎'getAllStackTraces'檢索系統範圍內的所有活動線程，但是如何獲取僅在我的應用程序中運行的線程？

代碼：

Set<Thread> threadSet = Thread.getAllStackTraces().keySet(); 
Thread[] threadArray = threadSet.toArray(new Thread[threadSet.size()]); 
Thread thread = null; 
for (int i = 0; i < threadArray.length; i++) { 
    thread = threadArray[i]; 
    Log.d(TAG, "thread.toString():" + thread.toString()); 
} 

輸出：

07-10 15:36:48.621 19333-19624/eu.men.m2sapp D/GcmIntentService: thread.toString():Thread[IntentService[GcmIntentService],5,main]

Answer 1

其實，沒有在貼輸出線程屬於我的應用程序

所有這些線程都屬於您的應用程序的進程。大部分來自框架，而不是你的代碼。

似乎「getAllStackTraces」檢索所有活動線程全系統

不，檢索你的進程中的線程。

我怎樣才能得到只在我的應用程序中運行的線程？

你已經是。

5號表示什麼？

我相信這是線程優先。
