How to get only the class name and not the full path?

Question

I know that using Context and the getClass().getName() method, I can get a string that represents the fully qualified name of the class, for example com.package1.package2.MainActivity .

How can I get only the last part, only the class name? In this case, it will be the MainActivity string.

I can do this with a simple split() method, but maybe there is a better way, more reliable.

Answer 1

That is all you need.

 MainActivity.this.getClass().getSimpleName(); 

Answer 2

To get only the class name and not the full path, you will use this expression:

 String className = this.getLocalClassName(); //or String className = getBaseContext().getLocalClassName(); //or String className = getApplicationContext().getLocalClassName(); 

Answer 3

Alternatively you can use:

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

Answer 4

No matter how you do it, you need to do an extra operation on top of getClass. I would recommend this for a split:

 String className = xxx.getClass(); int pos = className.lastIndexOf ('.') + 1; String onlyClass = className.substring(pos); 

Answer 5

• If you need the class name inside the method, use getLocalClassName()

• If you need a class name outside the method, use getClass().getSimpleName()

• If you want to reuse the class name in several methods within the same class, use private final String TAG = getClass().getSimpleName(); inside the class, and then use the TAG variable in each method.

• If you want to access the class name from static methods, use private static final String TAG = MainActivity.class.getSimpleName(); Now use TAG static variables in your static methods.

Answer 6

No other solutions work for me, I don’t know why. I use

 this.getClass().getName().replace("$",".").split("\\.")[3] 

cons: on one line, and you can use it in streams and listeners.

(in listeres, I get something like com.djdance.android.main $ 53)

Answer 7

If you want to get a name outside the class, you can call:

 MainActivity.class.getSimpleName() 

this way you can avoid a static static class.
