Windows用户:

使用脚本工具。确保您已经为系统设置了ADB环境。 Android Logcat脚本

保存到bat文件 编辑文件。用包id替换com.example.abc 双击打开文件或通过MobaXTerm打开(方便查找文本)

p/s:如果这个答案有帮助，让我们把我的回购星。谢谢!

在Android Studio 0.8.9中，我打开Android设备监视器，从设备列表中选择模拟器，并在LogCat选项卡中获得输出。

之后，我回到Android Studio的主视图，在Android DDMS选项卡的右侧选择Restore Logcat视图，它就在那里!

如果这不起作用，你可以在Android设备监视器中看到你的日志猫，就像我在第一句话中解释的那样。

Logcat的右边有一个小图标。您可以使用该图标打开和关闭logcat。我通常可以通过单击图标(可能几次)使logcat激活。

在终端中执行此命令。它将重新开始工作。

adb kill-server && adb start-server

就我而言，我试图用其他答案来解决这个问题，但没有结果。我无意中发现，空标签几乎从未显示(Android Studio 1.4)。因此，尝试在TAG中放入任何字母(空格无效)。

Log.wtf("x", "Android Studio Team, solve this, please!");

当其他方法都不管用的时候，我是这么做的。由于adb logcat工作得很好，我决定依赖它。在Android Studio的嵌入式终端中运行adb logcat -v color，输出与普通的logcat类似，并且允许代码链接工作:

但这也带来了一些问题:

您不能指定要监视的包。使用——pid=<your pid >选项，您可以查看单个进程的输出。但由于每次重新启动应用程序，PID都会发生变化，因此每次重新启动时都要重新运行此命令。 (在我看来)这些颜色令人讨厌。 输出字段没有与之前的消息对齐，整个事情没有很好地格式化，这使得跟踪logcat比它应该发生的要困难得多(尽管嵌入的logcat也发生了同样的情况)。

所以我决定制作自己的工具来自动监视我的包PID并美化logcat输出:

}

只需将这段代码转储到Logcat.java并使用以下方法进行编译:

javac Logcat.java

并在Android Studio的嵌入式终端中运行:

java Logcat <your.package.name>

例如:

java Logcat com.nomone.vr_desktop

结果如下所示:

它是高度可定制的，我在应用程序的第一部分分离了大部分选项，所以你可以很容易地调整颜色和格式。如果adb工具不在PATH环境变量中，只需在编译前在ADB_FILE_PATH变量中设置它的完整路径(在代码中)。

当应用程序正在运行时，您可以键入以下快捷方式:

C清除屏幕和本地缓冲区。 V, i, d, w, e来改变logcat的级别。 优雅地退出。Ctrl+c也可以。

不幸的是，在按完这些键后，您必须按回车键。似乎Java不允许在不编写系统特定代码的情况下从控制台输入单个字符。对不起!

免责声明

如果使用adb连接多个设备，这将不起作用。 我还没有彻底测试这个。我只在少数设备上使用过一段时间。 我还没有在Windows或Mac上测试，但我尽量避免使用任何特定于系统的东西，所以它应该仍然有效。

我希望这能解决你的问题:)
