废话不多说，直接上代码

主类

// An highlighted block
public class MainActivity extends AppCompatActivity {
//八个按钮对应八个对话框
    Button b1;
    Button b2;
    Button b3;
    Button b4;
    Button b5;
    Button b6;
    Button b7;
    Button b8;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
           //找到相对应的控件
        b1=findViewById(R.id.main_button1);
        b2=findViewById(R.id.main_button2);
        b3=findViewById(R.id.main_button3);
        b4=findViewById(R.id.main_button4);
        b5=findViewById(R.id.main_button5);
        b6=findViewById(R.id.main_button6);
        b7=findViewById(R.id.main_button7);
        b8=findViewById(R.id.main_button8);

        //new出创建的点击类
        MyOnclick myOnclick=new MyOnclick();

        //给每个控件设置点击事件
        b1.setOnClickListener(myOnclick);
        b2.setOnClickListener(myOnclick);
        b3.setOnClickListener(myOnclick);
        b4.setOnClickListener(myOnclick);
        b5.setOnClickListener(myOnclick);
        b6.setOnClickListener(myOnclick);
        b7.setOnClickListener(myOnclick);
        b8.setOnClickListener(myOnclick);
    }

  

自己写的点击类

// 自己写一个类继承View.OnClickListener，重写onClick方法
 public class MyOnclick implements View.OnClickListener{
        @Override
        public void onClick(View v) {
             //switch判断每一个控件的id并设置相对应的方法
            switch (v.getId()){
                case R.id.main_button1:
                    normal_Dialog();
                    break;
                case R.id.main_button2:
                    Single_Dialog();
                    break;
                case R.id.main_button3:
                    Check_Dialog();
                    break;
                case R.id.main_button4:
                    date_dialog();
                    break;
                case R.id.main_button5:
                    time_dialog();
                    break;
                case R.id.main_button6:
                    HorProgrssbar_Dialog();
                    break;
                case R.id.main_button7:
                    SpinnProgress_Dialog();
                    break;
                case R.id.main_button8:
                    Customer_Dialog();
                    break;
            }
        }
    }
