当按钮过多时处理办法

public class MainActivity extends AppCompatActivity {
 private Button btn1;
 private Button btn2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btn1=findViewById(R.id.btn1);
        btn2=findViewById(R.id.btn2);
       setLIsteners();

    }
    //设置点击事件
 private void setLIsteners(){
     onClick onClick=new onClick();
     btn1.setOnClickListener(onClick);
     btn2.setOnClickListener(onClick);
 }
private class onClick implements View.OnClickListener  {
       // @Override
        public void onClick(View view) {
            Intent intent=null;
            switch (view.getId()) {
                case R.id.btn1:
                    intent = new Intent(MainActivity.this, CheckBoxActivity.class);
                    break;
                case R.id.btn2:
                    intent=new Intent(MainActivity.this,CheckBoxActivity.class);
                    break;
            }
            startActivity(intent);
       }
    }
