Question

Im going to write some android app, which will basically consists of two activities. So first should have a lot of buttons (100+) and on click on any of them I will just get some special id and move to second activity. But is there any alternative to declare that hundreds of buttons and copy/paste one piece of code to every of them setting almost same onClickLister? Is there any special construction? Thanks

Edit: every of buttons are actually indexed from 1 to n. And on the click second activity will be launched and get that index to show it. I cant basically use any spinner or smth else, because there will be 3 rows of clickable things and each of them carring different images

Edit 2: so, to give you an idea, im going to do some table of buttons like in Angry Birds menu when you actually choosing the level you want to play. So, on click you will get id of button and start second activity

Call the method to add buttons

private void addButton(){       
    LinearLayout view = (LinearLayout) findViewById(R.id.linear_layout_id_here);            
     Button btn  = null;
     int w = 50;
     int h = 25;
    for(int i=1; i<100; i++) {
        btn = new Button(this);
        btn.setLayoutParams(new LayoutParams(w,h));
        btn.setText("button " +i);
        btn.setTag(""+i);
        btn.setOnClickListener(onClickBtn);  
        view.addView(btn);
        btn = null;
    }           
}

Call this method for handling onclick on button

    private View.OnClickListener onClickBtn = new View.OnClickListener() {
    public void onClick(View view) {
        final int tag = Integer.parseInt(view.getTag().toString());
        switch (tag) {
        case 1:
            // Do stuff
            break;
        case 2:
            // Do stuff
            break;

        default:
            break;
        }
    }
};
