我正在从列表动态创建复选框，现在如何检查用户从 android 列表中选择了哪个复选框

for (int i = 0; i < languageList.size(); i++) {

    HashMap<String, String> item_hash = new HashMap<String, String>();
    String lang = languageList.get(i).getLanguage();
    final String langId = languageList.get(i).getLanguageId();
    item_hash.put(langId, lang);

    ar[i] = langId;

    // String langId = languageList.get(i).getLanguage_id();
    item_list1.add(item_hash);
    cb = new CheckBox(parentActivity);
    cb.setText(languageList.get(i).getLanguage().toString());
    cb.setId(Integer.parseInt(languageList.get(i).getLanguageId()));

    Button btnSubmit = (Button) findViewById(R.id.btn_submit);

    // show location button click event
    btnSubmit.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            if(cb.isChecked()){
                  System.out.println("id "+cb.getText()+langId);

            }


        }
    });
}

也许使用 ListView 会更好。但是，如果您更喜欢使用您需要的方式和复选框数组

ArrayList<CheckBox> cbs = new ArrayList<Checkbox>();
for (int i = 0; i < languageList.size(); i++) 
{

    HashMap<String, String> item_hash = new HashMap<String, String>();
    String lang = languageList.get(i).getLanguage();
    final String langId = languageList.get(i).getLanguageId();
    item_hash.put(langId, lang);

    ar[i] = langId;

    // String langId = languageList.get(i).getLanguage_id();
    item_list1.add(item_hash);
    cb = new CheckBox(parentActivity);
    cb.setText(languageList.get(i).getLanguage().toString());
      cb.setId(Integer.parseInt(languageList.get(i).getLanguageId()));
    cbs.add(cb);

Button btnSubmit = (Button) findViewById(R.id.btn_submit);

// show location button click event
btnSubmit.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View arg0) {
        for (int i = 0; i < languageList.size(); i++)
            if(cbs.get(i).isChecked())
                 System.out.println("id "+cbs.get(i).getText()+langId);

    }
});
