要从Android设备获取logcat，我使用adb shell logcat（在混合中也使用了一些grep过滤）。
示例输出如下：
E/com.samsung.app( 3739): [MSC]>>>...
I/InputDispatcher( 2882): Delivering ...
D/ProgramMonitor( 3770): START ...
D/ProgramMonitor( 3770): LAUNCHER_RESUME...
I/Debug ( 3815): onReceive...
E/Debug ( 3815): receive ...
D/ClientReporter( 3036): ...
我的问题是，如何根据日志的首字母更改输出的颜色。所以“E”用红色打印，“D”用绿色打印等等......就像在Eclipse中看日志的方式类似。
谢谢
我使用我在这里找到的python脚本：
Modifying the Android logcat stream for full-color debugging
如果你愿意，它真的很容易使用和修改。

我想要一些简单的东西，并且不想导入一些解析和重新格式化输出的巨大脚本，所以我想出了这个。这确实只是打印输入行，相应地添加颜色代码。

请注意，这适用于标准的-v time格式，但当然可以修改为适合您喜欢的任何格式。
