使用OnClick事件的最佳方法是什么？

Question

There are 2 ways to use OnClick event in android studio.

First method is,

Btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    };

Second way is,

in MainActivity

Btn.setOnClickListener(this);

and Override method onClick

@Override
   public void onClick(View v) {
       switch(v.getId()) {
           case R.id.button1:
           // do stuff;
           break;
           case R.id.button2:
           // do stuff;
           break;
       ...
   }

What is the best and most efficient way from above two??

Answer 1

Both are good. Nothing in wrong on above mentioned methods. But I would prefer second one with switch statements when I have to listen click events with many views on the other hand If want to listen click event for a view or two I prefer to use first one. NOTE: If click events are more than to implement anonymous way (as you implemented in first example) the line of code increases a lot. It looks tedious and to maintain code becomes harder. But other developer may feel comfortable with this
