I have added 9 CheckBox in my Fragment which is getting checked according to the response from JSON. If user wants to update his/her profile, He/she can check/uncheck any of them. Now I have to confirm that how many of them are checked and create an Array as a parameter according to that. I am not using any adapter for that. please let know how to set the condition to get the value of only checked checkboxes

我试图做这样的

cb_prfl_setng_general=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_general);
    cb_prfl_setng_economics = (CheckBox)rootView.findViewById(R.id.cb_prfl_setng_economics);
    cb_prfl_setng_business=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_business);
    cb_prfl_setng_social=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_social);
    cb_prfl_setng_politics=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_politics);
    cb_prfl_setng_entertainmnt=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_entertainmnt);
    cb_prfl_setng_technology=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_technology);
    cb_prfl_setng_spritual=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_spritual);
    cb_prfl_setng_sports=(CheckBox)rootView.findViewById(R.id.cb_prfl_setng_sports);



     if(cb_prfl_setng_general.isChecked()){

                String[] Interest = {"catagory_id=1"};

            }else if(cb_prfl_setng_economics.isChecked()){

                String[] Interest = {"catagory_id=1","catagory_id=2"};

            }else if(cb_prfl_setng_general.isChecked()){

                String[] Interest = {"catagory_id=1","catagory_id=2","catagory_id=3"};

            }else if(cb_prfl_setng_entertainmnt.isChecked()){

                String[] Interest = {"catagory_id=1","catagory_id=2","catagory_id=3","catagory_id=4"};
            }

但我不认为这是得到确切价值的正确方法。

But I don't think this is the right way to get the exact value.

推荐答案

您需要单独测试每一个复选框和积累的类别ID：

You need to test each checkbox separately and accumulate the category ids:

    List<String> interestList = new ArrayList<String>();

    // for each checkbox checked, accumulate a category id in the list
    if (cb_prfl_setng_general.isChecked()) {
        interestList.add("catagory_id=1");
    }

    if (cb_prfl_setng_economics.isChecked()) {
        interestList.add("catagory_id=2");
    }

    if (cb_prfl_setng_general.isChecked()) {
        interestList.add("catagory_id=3");
    }

    if (cb_prfl_setng_entertainmnt.isChecked()) {
        interestList.add("catagory_id=4");
    }

    .
    .
    .

    // convert the list into an array
    String[] interest = interestList.toArray(new String[interestList.size()]);

    System.out.println("interest");
    for (String str : interest) {
        System.out.println(str);
    }
