IntelliJ/Android Studio: remove unnecessary use of 'this.'

Question

I am working on a project where previous developers added lots of this.x code which in my opinion makes it longer and thus less readable. And it was placed all over the project by some Eclipse save action.

What I am looking for is an IntelliJ refactoring method that I can refactor all self-references on the whole project so that this:

this.something = "foo";

becomes this:

something = "foo";

Is there anything like this (I'm using Android Studio 1.2), or do I have to run a regex replace and make sure that nothing breaks?

One way which you can achieve this is by using Inspections. You can edit the inspections that are run on your code by going to Settings > Editor > Inspections. The one that you want to change is found within Java > Code Style issues and it's called "Unnecessary 'this' qualifier".

After checking and applying this inspection it will highlight areas of code which unnecessarily use the this keyword. At the moment this won't have any immediate affect on your code base and you would have to go through each instance one by one. In order to fix a batch of inspections warnings then go to Analyze > Inspect code...

From this option you can choose to run the inspection on specific files or the whole project. This will highlight any instances of code which conflict with your Inspection rules, for example this newly added rule. To apply the fix all you need to do is right click on the issue or group of issues that you wish to fix and then select Apply fix.
