单击按钮是否不适用于材料设计？

Question

我已经使用Material Design Library创建了一个按钮 ，并且我做对了设计，代码是正确的，但是它没有响应单击，对于响应的按钮我该怎么办 单击，我要修改一些代码 按钮功能起作用。

MainActivity

public class MainActivity extends AppCompatActivity {

                @Override
                protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.activity_main);

                    ButtonRectangle buttonSelectColor = (ButtonRectangle) findViewById(R.id.button4);

                    buttonSelectColor.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View arg0) {
                          Log.i("trace","don");

                        }
                    });
                }
                // End ;
            }
