在 Android Studio/Intellij idea 中自动生成 Android Log TAG

Question

In Intellij Idea when i typing psfs and then press Ctrl+J IDE was getting me a dialog :

And when i press Enter i get an

I know where i can customize my own output

But i can't any doc's how i can write my own live template.

In the end i want to get next result :

Typing : psfst -> press Ctrl+J -> press Enter

Result :

public static final String TAG = <currentClassName>.class.getSimpleName();

It will be so helpfull, because i have a habit to log my classes.

Answer 1

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 :

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

Click Ok , Apply , Ok and use.

Answer 2

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

Answer 3

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

Add Kotlin pressing "change" button and check Kotlin

and after that it will work again!

Updated: 2020

Android Studio: 3.6.2

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

4. Add a description
5. 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

Answer 4

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

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

Answer 5

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

对于 Kotlin，创建一个实时模板，使用private val TAG = $CLASS_NAME$::class.java.simpleName作为模板文本，并在 CLASS_NAME 的 set 表达式中作为 kotlinClassName() 在编辑变量中。
