保持多OnClickListeners在一个类中 [英] Keeping multiple OnClickListeners in one class

问题描述

我还挺新的Andr​​oid，这将提高我的应用程序中的LOF，如果我库仑保留若干OnClickListenres在一个类中。我所thiking的是这样的：

I am kinda new to Android and it would improve my application a lof if I coul keep several OnClickListenres in one class. What I am thiking of is something like this :

Public class OnClickListeners {

public Button.OnClickListener open;
public Button.OnClickListener doSomethingElse;
public Button.OnClickListener etc;

    public OnClickListeners() {
        open = new Button.OnClickListener()
        {
                public void onClick(View view)
                {
                    DetailList.SetId(view.getId());
                    Intent intent = new Intent(view.getContext(), DetailList.class);
                    startActivityForResult(intent, 100);
                }
        };
    }
}

所以，我可以再引用它在其他B级这样的

So I can then reference it in other class B like this

button1.setOnClickListener(OnClickListeners.open);

任何虽然该怎么办呢？
Android SDK中似乎是反对我，因为我现在可以现在弄明白了大约2天...

Any though how to do it? Android SDK seems to be against me as I can figure it out now for about 2 days now...

感谢您的建议和帮助。

推荐答案

有是巩固所有的匿名类为一体，并在视图切换圆滑的方​​式。这个工作最好，如果你事先知道哪些按钮将使用clicklistener：

There is a sleek way to consolidate all your anonymous classes into one and switch on the view. This works best if you know ahead of time which buttons will be using the clicklistener :

public class AndroidTestClickListenerActivity extends Activity {

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button1 = (Button) findViewById(R.id.button1);
        button1.setOnClickListener(new MyClickListener());

        Button button2 = (Button) findViewById(R.id.button2);
        button2.setOnClickListener(new MyClickListener());

        Button button3 = (Button) findViewById(R.id.button3);
        button3.setOnClickListener(new MyClickListener());
    }


}

class MyClickListener implements View.OnClickListener {
    @Override
    public void onClick(View arg0) {
        switch (arg0.getId()) {
            case R.id.button1:
                // do soemthign for button1
                break;
            case R.id.button2:
                // do something for button2
                break;
            case R.id.button3:
                // do something for button3
                break;
            default:
                // do something for any other button

        }

    }
}
