Automatically modify file names in batches

demand

​ As an android development, it is often necessary to import UI cuts into the project, but UI cuts files are usually named in Chinese, and in the android project, the drawable file name cannot use Chinese characters, and English cannot have uppercase letters. Spaces, and for readability, we need to separate words with "_", so we need to translate the file name of the cut image to the style we need

achieve

1. Apply to open Baidu Universal Translation API, get "APP_ID and key", these two are required

   https://api.fanyi.baidu.com/doc/12

   After the application is successful, you can view it in the developer information

2. Code

   There are four java files

   

   MD5, HttpGet, and TransApi are the demo files translated by Baidu. We need to use them to use Baidu's translation API

   https://fanyiapp.cdn.bcebos.com/api/demo/java.zip can be downloaded through the link

   FileNameChange is a file that realizes our specific needs by calling the files in the Baidu translated demo

   FileNamechange.java

   import org.json.JSONObject;
   
   import java.io.File;

3. After the code is implemented, it is run. I found here that the above code cannot be run directly in android studio, and it cannot be solved temporarily by consulting the information.

   So the code can only be run in the java environment, such as running in idea, if there is a better way, you can leave a message in the comment area, thank you

​ Although I haven't found the best way, I can still solve the problem. I hope it will help you a little bit.
