I find a solution

1) Create a new live template in plain group
2) In template text :

private static final String TAG = $CLASS_NAME$.class.getSimpleName();

3) Define a usage scope :

4) Choose a shortcut :

enter image description here

finally click on Edit variables and change expression value to className()

enter image description here

Click Ok , Apply, Ok and use.

There already exists such shortcut in Android Studio - write logt and enter while cursor is at the class scope.

  • Not exactly. It will generated template as `private static final String TAG = "";` not requested. But I will plus, because however it good 0,02$ to this. – Sergey Shustikov May 31 '16 at 08:08

It's super simple in Android studio, just type logt and press Tab.

It generates: private static final String TAG = "xyzActivity";

For those using Android Studio 3 and Kotlin it is necessary to change how Live Templates set:

Editor >> Live Templates >> AndroidLog

By default it is just for Java

enter image description here

Add Kotlin pressing "change" button and check Kotlin

enter image description here

and after that it will work again!

Updated: 2020

Android Studio: 3.6.2

enter image description here

Steps:

  1. Add
  2. Call logtk are whatever you want to call
  3. Use this code as template text
private val TAG = this::class.java.simpleName
  1. Add a description
  2. Do it applicable to Kotlin: in my case I used just for Class

Update June 2020

There's no need to set anything up anymore. Android Studio 4.0 comes with this functionality by default. The same with Toast

  • `this` is evaluated for each instance. But the class name is static. Therefor it might be better to put the Log TAG into the companion object. – ceving Nov 24 '22 at 16:19

Another solution is not use a default TAG for each class and use this method to get the TAG:

public class Utils {
        public static String getTAG(Object o) {
            StackTraceElement[] elements = Thread.currentThread().getStackTrace();

            int position = 0;
            for (int i = 0; i < elements.length; i++) {
                if (elements[i].getFileName().contains(o.getClass().getSimpleName())
                        && !elements[i+1].getFileName().contains(o.getClass().getSimpleName())){
                    position = i;
                    break;
                }
            }

            StackTraceElement element = elements[position];
            String className = element.getFileName().replace(".java", "");
            return "[" + className + "](" + element.getMethodName() + ":" + element.getLineNumber() + ")";
        }
}

Example call from MainActivity - onResume:

Log.v(Utils.getTAG(this), "hello world");

Log output:

[MainActivity](onResume:79): hello world

For Kotlin create a live template with private val TAG = $CLASS_NAME$::class.java.simpleName as the template text and in set expression for CLASS_NAME as kotlinClassName() in edit variables.
