Intellij (Android studio) member variable prefix

In Mac OS

• Android Studio -> Preferences -> Code Style -> Java
• on the right panel, click on the right arrow until you see code generation tab
• Click ok

In AS 2.2.1:

File > Settings > Editor > Code Style> Java > Code Generation > Naming > Name Prefix Field / Name Prefix Static Field

1. Open Android Studio's preferences (from the Android Studio menu on Mac and from File -> Settings on Windows and Linux).
2. Expand Editor and then expand Code Style.
3. Select Java, then choose the Code Generation tab.
4. In the Naming table, select the Field row and add m as the name prefix for fields. Then add s as the name prefix for static fields.

5. Click Ok

Try going to File-->Other Settings-->Default Settings. Your should be able to make prefixes for every other project that you do if you change prefix settings with the scheme set to default instead of Project. The prefix change would be in Java and Code Generation. That will fix setters and getters.
