In Android Studio, go to Android-> Edit Filter Configurations

Then type in the name you gave the logs. In my case, it's called "wawa". Here are some examples of the types of filters you can do. You can filter by System.out, System.err, Logs, or package names:

I had trouble turning on the filters in Logcat. To see the filters in Android Studio 3.2, you have to toggle 'Floating Mode' on and off again to make the filters reappear.

One alternative that works for me is to select the <code>Show only selected application</code> option in the filter menu:

blocks|key|4704873|text|只是补充一下我自己的错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4704874|确保在使用Emulator和真实设备时，在logcat选项卡上方左侧的下拉列表中切换到正在调试的设备。|4704875|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Just to add my own mistake: 

make sure that when you are using the Emulator and a real device, to switch to the device you are debugging in the dropdown on the left above the logcat tab.

In my logcat there is too much output, so I'd like to filter it using some keywords, basically displaying only the output containing the keyword(s). Is there a way to do that in Android Studio through the UI?

Android Studio

Android

在我的logcat中有太多的输出，所以我想使用一些关键字来过滤它，基本上只显示包含关键字的输出。有没有办法在Android Studio中通过UI来做到这一点呢？
