Follow the above steps to open the database folder of your app in Android Device explorer and in there you can see six files, The first three is named as android and the last three is named as your database name. You only have to work with the last three files, save these three files at your preferred location. You can save these files by right-clicking to the file and click save as button (like I have my database named as room_database and so three files are named as room_database, room_database-shm, and room_database-wal. Rename the corresponding file as follows:-

1)从room_database到room_database.db 2) room_database-shm到room_database.db-shm 3) room_database-wal到room_database.db-wal

现在在任何SQLite浏览器中打开第一个文件，这三个文件都将被填充到浏览器中。

从Android Studio查看数据库:

选项1:

Download and install SQLiteBrowser. Copy the database from the device to your PC: Android Studio versions < 3.0: Open DDMS via Tools > Android > Android Device Monitor Click on your device on the left. You should see your application: Go to File Explorer (one of the tabs on the right), go to /data/data/databases Select the database by just clicking on it. Go to the top right corner of the Android Device Monitor window. Click on the 'pull a file from the device' button: A window will open asking you where you want to save your database file. Save it anywhere you want on your PC. Android Studio versions >= 3.0: Open Device File Explorer via View > Tool Windows > Device File Explorer Go to data > data > PACKAGE_NAME > database, where PACKAGE_NAME is the name of your package (it is com.Movie in the example above) Right click on the database and select Save As.... Save it anywhere you want on your PC. Now, open the SQLiteBrowser you installed. Click on 'open database', navigate to the location you saved the database file, and open. You can now view the contents of your database.

选项2:

转到这个Github存储库，并按照自述文件中的说明在您的设备上查看您的数据库。你得到的结果是这样的:

就是这样。当然，在发布应用之前，你应该撤销所有这些步骤。

我得把数据库从手机移到电脑上。现在我使用这个制作精良的免费应用程序，它有很多功能。它工作在API 4.1+与根设备。 如果你找到不用根也能吃的方法，请告诉我。

最后，Android Studio通过数据库检查器选项卡支持此功能。您可以轻松应用视图/更新/查询操作。它现在还不是稳定的渠道，但你可以尝试Android Studio 4.1 Canary 5或更高版本。

您可以在这里看到数据库检查器的样子

你可以在这里下载相应的版本

最后，我找到了一个最简单的解决方案，不需要打开DDMS。

实际上，解决方案是基于@Distwo提到的，但它不必那么复杂。

首先，记住数据库文件在设备中的路径，它应该始终相同。 例如我的是:/data/data/com.XXX.module/databases/com.XXX.module.database

其次，执行这个命令，将数据库文件拉到PC上

 adb pull /data/data/com.XXX.module/databases/com.XXX.module.database /Users/somePathOnYourPC/

您需要做的就是复制并存储这个命令，然后您就可以一次又一次地使用它。

第三，如果你得到了Permission Denied或类似的情况，只需在前面的命令之前运行adb root。
