How to get class name only, not full path?
AndroidAndroid Problem Overview
I am aware that using Context and a method getClass().getName() I can get a string which represent full class name, like com.package1.package2.MainActivity.
How can I get only the last part, class name only? In this case it would be MainActivity string.
I can do it with a simple split() method, but maybe there is a better way, more reliable.

Solution 1 - Android
This is all you need.
MainActivity.this.getClass().getSimpleName();
Solution 2 - Android
To get only the name of the class, not full path you will use this expression:
String className = this.getLocalClassName();
//or
String className = getBaseContext().getLocalClassName();
//or
String className = getApplicationContext().getLocalClassName();
Solution 3 - Android
Alternatively, you could use:
private static final String TAG = MainActivity.class.getSimpleName();
Solution 4 - Android
-
If you need class name within a method, use
getLocalClassName() -
If you need class name outside a method, use
getClass().getSimpleName() -
If you want to reuse the class name in multiple methods within the same class, then use
private final String TAG = getClass().getSimpleName();within the class and then use TAG variable in every method. -
If you want to access the class name from static methods, then use
private static final String TAG = MainActivity.class.getSimpleName();now use the static variable TAG within your static methods.

No matter what way you do it, you'll need to perform an extra operation on top of getClass. I'd recommend this over split:
String className = xxx.getClass();
int pos = className.lastIndexOf ('.') + 1;
String onlyClass = className.substring(pos);
Solution 6 - Android
Use the getSimpleName method:
String name = getClass().getSimpleName();
Solution 7 - Android
In kotlin you should use:
val className = javaClass.simpleName
Solution 8 - Android
Kotlin way: MainActivity::class.java.simpleName
Solution 9 - Android
No other solutions work for me, dunno why. I'm using
this.getClass().getName().replace("$",".").split("\\.")[3]
cons: in one string, and you can use it in threads and listeners.
(in listeres I get something like com.djdance.android.main$53)
Solution 10 - Android
If you want to get the name outside the class you can call:
MainActivity.class.getSimpleName()
in this way you can avoid to make your class static.
