I would like to know the following, I have: ImageButton btneditarusuario; and a TextView editarusuario; , clicking on either one starts startActivity .

How to group ImageButton with TextView so you do not have to repeat the code?

The code:

editarusuario.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    startActivity(new Intent(getApplicationContext(), EditarUsuario.class));
                }
            });

btneditarusuario.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    startActivity(new Intent(getApplicationContext(), EditarUsuario.class));
                }
            });

You have three possibilities:

Declare a class that implements the View.OnClickListener

private class ClickListener implements View.OnClickListener {
    @Override
    public void onClick(View v) {

        startActivity(new Intent(getApplicationContext(), EditarUsuario.class));
    }
}

and pass it to each of the setOnClickListener() :

ClickListener listener = new ClickListener();

editarusuario.setOnClickListener(listener);
btneditarusuario.setOnClickListener(listener);

Make the Activity implement the View.OnClickListener interface

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        .....
        .....

        editarusuario.setOnClickListener(this);
        btneditarusuario.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        startActivity(new Intent(getApplicationContext(), EditarUsuario.class));  
    }
}

Use the android:onClick="" attribute with the same method name in the ImageButton and TextView

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ....
    ....
    android:onClick="startActivityEditarUsuario" />

<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ....
    ....
    android:onClick="startActivityEditarUsuario" />

and declare the method in Activity

public void startActivityEditarUsuario(View view) {
    startActivity(new Intent(getApplicationContext(), EditarUsuario.class));  
}
