所有这些都无济于事，我的日志猫功能失常。

After a lot of angry searching I found a solution that seems to work: 1. Make sure logcat itself is working (use DDMS from Tools->Android) and if it does close DDMS window again 2. Now go to Tab 5 (Debug), there select Logcat (this is not the same logcat as in Window 6!) 3. The window is empty just like Window 6, but now start a debugging run. For me logcat in the Debug window now started to show all the stuff again! Also when normally running the application the Debug->logcat view is still functional while the Tool Window #6 "logcat" is disfunctional as before

这是一个黑客，但是它会导致正常的logcat行为，突出显示您调试和开发所需的行和语法。 从现在开始，您需要通过调试窗口访问它。

这不是一个技术性的答案，但您可能想要检查logcat的搜索框。如果输入了任何字符，你的logcat将为空，因为它将搜索特定的字符或单词，然后如果它不存在，你的logcat日志将完全为空。

尝试点击“Android”视图最右边的图标，你应该在Android视图上看到Logcat选项卡(你可以通过按Alt+6打开Android视图)

重新启动logcat。它是固定的

需要连续两次按“Alt+6”重新启动logcat窗口。这样它就会显示日志输出。

问题主要发生在调试模式。

我刚把它修好了。在DDMS显示的最右边寻找恢复Devices Logcat视图和ADB视图的小图标。

When the DDMS first came up with both the "ADB Logs" and the "Devices | logcat" tab showing. The "Devices | logcat" is the one that should be showing the device output, but was blank. Somehow I managed to hide one or the other of those tabs, I forget exactly how. But, off to the right there was a tiny icon that said "Restore ADB" view, and I clicked it and it came up. Then there was another tiny icon that said "Restore Devices logcat view". I clicked that, and all of a sudden it appeared and was showing the device output again.
