How to extract all lines from application in Java

Question

In the Android application, all string values ​​are gated (labels, dialog names, buttons, etc.). My task is to extract all of these lines into a resource file. Without manually using the code and doing a lot of c / p, is there a way to extract all the lines from the application? Using regular expressions? I was thinking of writing a "Template" with the following type of ". *" Or, somehow, sort out the code?

Edit: I am aware of external lines for Eclipse, but it creates a .properties file and I need a .xml file. So, converting it to a .xml file will take some effort.

I was thinking of writing a simple program that would extract all the lines with the names of the classes in which they were found.

Answer 1

Eclipse provides an export string wizard. For Android solutions: External lines for an Android project .

Hope this helps.

Answer 2

I wrote a short program that will help me with this. I had a file with more than a hundred lines in it, so just pressing Ctrl + 1 → Enter in each line would be too complicated.

The little program takes the file location of your .java file as input and puts the information in your console for C & P. ​​It could be improved to scan through the file system and do it for all .java files, but that was enough for mine goals ...
