以 MainActivity 为例，为 MainActivity 添加 DataBinding

		
import cn.netkiller.student.databinding.ActivityMainBinding;
		
		

		
public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();
    private ActivityMainBinding binding;
		
		

		
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
	}
