Android multi-language settings, Android multi-language

The multilingual switchover function was used in recent projects. Note that in the xml file and code, all the places where the text string is used ensure that the string text used is from the string in the values folder. in xml.

Therefore, two to three files are required for multiple languages. 1. The string. xml file in the values folder stores the default language type that your app uses when there is no language setting. 2 values-en folder (this folder is created by yourself, of course, it can also be another name string. xml. Here it stores the English text corresponding to each text. 3values-tw (Traditional Chinese)

Note that the text variables in the string. xml file under the three folders must be consistent in number and Corresponding names.

The following is the code for switching. I selected an important explanation.
