Answer 1

Here is some sample code of how to add a button named Add. You should declare the variable as a member variable, and the naming convention for member variables is to start with the letter "m".

Hit Alt+Enter on the classes to add the missing references.

Add this to your activity_main.xml:

Add this to your MainActivity.java:

public class MainActivity extends AppCompatActivity {

    Button mButtonAdd; 

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mButtonAdd = findViewById(R.id.buttonAdd);

        mButtonAdd.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // do something here
            }
        });
    }
}
