查看任务的活动堆栈

我刚开始开发一个简单的Android应用程序，而我还在学习这个平台。

我正在使用Eclipse IDE和ADT插件0.9.6。

我需要知道是否可以查看与任务关联的Activity堆栈？

有没有通过DDMS工具或任何其他技术的方式？

基本上我需要的是能够看到一个任务的堆栈活动，以确保应用程序的行为如预期。

我知道，通过使用Intent对象中的标志和<activity>元素的某些属性，可以在一定程度上控制任务行为。

不过，有一种工具 – 特别是在debugging模式下 – 这样可以让开发人员直接看到Activity堆栈。

从命令行，您可以使用： adb shell dumpsys activity

这要求活动pipe理器打印当前状态的转储。 第一部分是完整的活动历史，由任务组织。 之后还会打印很多东西，所以您可能需要向上滚动一下才能find您想要的东西。

以下是其输出示例（具体内容因平台版本而异），显示了与两项活动联系的首要任务，以及后面的具有一项活动的启动程序：

当前活动pipe理器状态中的活动：

Answer 2

您可以使用

 $ adb shell dumpsys activity activities | sed -En -e '/Stack #/p' -e '/Running activities/,/Run #0/p' 

在您的命令行中查看系统中的任务和后台堆栈。

或者，您可以尝试TaskLogger ，一个我创build的简单工具，它可以监视您的应用程序中的所有活动和任务，并在Logcat中实时输出。

Answer 3

我知道这是一个老问题，但是现在这个function已经融入到了Android Studio中：

然后在生成的文本文件中searchACTIVITY （全部大写）：

Answer 4

我总是检查这部分的长转储消息..

  Running activities (most recent first): TaskRecord{4307f828 #56 A com.demo.proj U 0} Run #4: ActivityRecord{425a6838 com.demo.proj/com.demo.proj.Activity2} Run #3: ActivityRecord{427dc860 com.demo.proj/com.demo.proj.Activity1} Run #2: ActivityRecord{420cba18 com.demo.proj/com.demo.proj.MainActivity} TaskRecord{430341d0 #2 A com.lge.launcher2 U 0} Run #1: ActivityRecord{41e0af68 com.lge.launcher2/.Launcher} TaskRecord{44e26ce0 #18 A com.lge.appbox.client U 0} Run #0: ActivityRecord{41e9dbe8 com.lge.appbox.client/.AppBoxClient} 

注意：运行＃4是您现在在屏幕上看到的活动。 🙂

Answer 5

您可以使用工具hierarchyviewer.bat。 它是android SDK的一部分。 它只适用于模拟器。 但它更舒适，更清晰。

编辑：我刚刚在Eclipse中find了层次结构查看器！ 它也适用于真实的设备。 只需打开透视图Windows-> Open Perspective-> Hierarchy View在列表中，您可以看到所有连接的设备和仿真器以及活动堆栈。 另外在树形视图中，您可以看到更多关于视图本身的信息。

编辑：层次结构查看器将只能用于开发人员设备。 生产设备不能出于安全原因。 欲了解更多信息，请看下面的答案

解决scheme：“adb shell dumpsys活动”不适用于TabActivity。 当选中每个标签项目时，相应的活动将被启动。 但是当使用'adb shell dumpsys activity'时总是返回'main'活动：

 public class main extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { Log.e("xyz", "start main..............."); super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Resusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, widgets.class); spec = tabHost.newTabSpec("Widgets").setIndicator("Widgets", res.getDrawable(R.drawable.tab1)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, layouts.class); spec = tabHost.newTabSpec("Layouts").setIndicator("Layouts",res.getDrawable(R.drawable.tab2)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, composite1.class); spec = tabHost.newTabSpec("Composite").setIndicator("Composite",res.getDrawable(R.drawable.tab3)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, imageMedia.class); spec = tabHost.newTabSpec("Image_Media").setIndicator("Image&Media",res.getDrawable(R.drawable.tab4)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, timeDate.class); spec = tabHost.newTabSpec("Time_Date").setIndicator("Time&Date",res.getDrawable(R.drawable.tab5)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, transitions.class); spec = tabHost.newTabSpec("Transitions").setIndicator("Transitions",res.getDrawable(R.drawable.tab6)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, advanced.class); spec = tabHost.newTabSpec("Advanced").setIndicator("Advanced",res.getDrawable(R.drawable.tab7)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, others.class); spec = tabHost.newTabSpec("Others").setIndicator("Others",res.getDrawable(R.drawable.tab8)).setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, Dynamic.class); spec = tabHost.newTabSpec("Dynamic").setIndicator("Dynamic",res.getDrawable(R.drawable.tab2)).setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTab(0); } 

}

如果你想检查特定包的任务堆栈，下面的命令将会执行：

 adb shell dumpsys activity activities | grep PACKAGE_NAME | grep Hist
