推荐答案

请一个单独的类，将得到的按钮作为参数，将创建并设置相应的onClick监听器。然后，只需调用，从那里你需要的类。像这样的：

Make a separate class which will get the buttons as parameters and which will create and set the appropriate onClick listeners. Then just call the class from where you need. Like this:

public class ButtonInitializer {

  private Button btn1, btn2, btn3, btn4;

  public ButtonInitializer(Button btn1, Button btn2/* and another 2 here*/) {
     this.btn1 = btn1;
     this.btn2 = btn2;
     this.btn3 = btn3;
     this.btn4 = btn4;
  }

  public void init() {
     btn1.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick() {
           // your code
        }
     }
     // and for other buttons
   }

在您的活动：

new ButtonInitializer(btn1, btn2, btn3, btn4).init();
