This time I will bring you several Click response methods for Button. What are the precautions for using Button's Click response method? The following is a practical case, let's take a look.

Button is used a lot. I have sorted out its

event handling methods here and found that there are many implementation methods. I prefer the second one. What about you, which one is most commonly used? One?

Implementation one:

Button bt_Demo = (Button)findViewById(R.id.bt_Demo);
   bt_Demo.setOnClickListener(new OnClickListener()
   {
       @Override
       public void onClick(View v)
       {
           //响应Clicked事件
//......
       }
   });

Implementation two:

Button bt_Demo = (Button)findViewById(R.id.bt_Demo);
   bt_Demo.setOnClickListener(listener);
   private OnClickListener listener = new OnClickListener(){ 
       @Override
       public void onClick(View arg0) {
           // TODO Auto-generated method stub        
            switch(arg0.getId()){ 
                case R.id.bt_Demo:
                   //响应Clicked事件
//......
break;
                default:
                break;
                }
       }
   }

Copy after login

Implementation three:

Button bt_Demo = (Button)findViewById(R.id.bt_Demo);
   bt_Demo.setOnClickListener(new ButtonListener());
   private class ButtonListener implements OnClickListener{
       @Override
       public void onClick(View arg0) {
               //响应Clicked事件
//......
       }        
   }
