![]() All we have to do is select our method clickButton, which should appear in the dropdown, and we are done. It also contains the onClick attribute, which runs a method when the button is clicked/pressed in the app. It contains the text attribute that I updated to ‘Log’ that updates the text that the button displays. Both column span and row span are used 3. There is a window on the right-hand side called Attributes, it contains a lot of different attributes that affect the button. The following shows a rough sketch of the keypad we will build. Going back to the design page after adding the button to the Application. So how do we use the new custom method on the design page? We need to look at the attributes for the Button Object and use the method Button Listener It is also possible to change the EditText name to something more concise and descriptive, but since the example was small, it is fine to use the default name. The name for the edit text will vary depending on the EditText object you drag in. So I create the clickButton method since it’s exactly what we are planning to do with the button, since we are not planning on returning anything after we click the button it has the type of void. When the user gives focus to an editable text view such as an EditText element and the user has a hardware keyboard attached, all input is handled by the. ![]() Going back to the MainActivity.java file, we need to create a method that accesses the EditText Object and outputs its contents to stdout. So how to set up the button? It requires creating a Java method and using it on the Design Layout page. So what is going on? The button is not connected to anything, so clicking the button is not going to do anything. But after running the app, the text still is not coming through. ![]()
