试试这个..

  @Override
        protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_place_bid);
          String[] sh=item_list();
          int array_length=jArray.length();
          LinearLayout linearLayout = (LinearLayout) findViewById(R.id.lyout);

          for(int c=0; c<jArray.length();c++){
            CheckBox chk=new CheckBox(this);
            chk.setId(c+1);
            chk.setText("Click to add values");
            chk.setTextColor(Color.GRAY);
            chk.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
              @Override
              public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
               String s="x"+buttonView.getId();
               Toast.makeText(getApplicationContext(), s, Toast.LENGTH_LONG).show();

                switch(buttonView.getId()){

                  case 1: // do something on 1st checkbox
                        break;

                  case 2: //do something on 2nd  checkbox
                       break;

                //And SO ON for all checkboes
            }  
           }
          });
            linearLayout.addView(chk);
          }


        }

如果SetId(Int)无效，那么您可以改用setTag(int)和getTag()。
