添加headView时包含button如何获得点击事件以及protected 方法使用

setupHeaderButtons() method?是 protected它只能被使用在基类或者继承基类的类这里是 BaseActivity

public class BaseActivity extends Activity {     protected View.OnClickListener mButtonListener;      protected void setupHeaderButtons() {         findViewById(R.id.header_btn_1).setOnClickListener(mButtonListener);         // ...         findViewById(R.id.header_btn_n).setOnClickListener(mButtonListener);     } }  public class FirstActivity extends BaseActivity {     @Override     public void onCreate(Bundle b) {         super.onCreate(b);         setContentView(R.layout.first_activity);          // This needs to be done *after* the View has been inflated         setupHeaderButtons();     } }
