Hello ! I’m Xavier Jouvenot and in this small post, I am going to explain how to set the visibility of a button.

Self promotion: You can find other articles on Android development on my website 😉


To specify the visibility of a , there are several solutions and the first one we are going to specify a default visibility for a .

To do so, we are going to modify the XML definition, and add one attribute to it. This attribute is and tell if you want the button to be visible are not. By default, this attribute is set to visible.

Here is how such XML definition looks like:

<!--Some attributes-->
<!--Some other attributes -->


Specifying the attribute in the XML is great! But if you want to modify the visibility of a while the program is running, then, you must use some Java code and the method . Here is how it looks like:

Button button = findViewById(R.id.buttonId);
