OnClickListener() implementation of Array Of Buttons in Android

I am writing an Android Application which outputs some array of buttons dynamically. My question is how to implement onClickListener() functionality for Arra开发者_如何转开发y Of Buttons. I mean how to recognize the button that is clicked in public void onClick() method ? I need to display a toast based on the button that is clicked.

The onClick() method is passed the View that was clicked...

public void onClick(View v) {
...
}

Use v.getId() to return the button's identifier.

you could create a class derived from OnClickListener, that, in the constructor, takes the button ID.

Something like:

class MyClickListener extends OnClickListener() {
    int buttonId;  

    MyClickListener(int id) {  
        buttonId = id;  
    }  

    protected void onClick(View v) {  
        ... // do something with buttonId
    }  
}

Then, in your onCreate, you would do:

int i, nb = mButtons.size(); // if mButtons is a List<Button>
for (i = 0; i < nb; i++) {
    mButtons.get(i).setOnClickListener(new MyClickListener(i));
}
