无法取消选中动态单选组中已选中的单选按钮 [英] not able to unchecked the already checked radio button in dynamic radio group

问题描述

如果我第一次设置了一个单选按钮，它就可以正常工作.但是如果我通过调用 .setChecked(false); 取消选择它.然后，即使我尝试通过调用 setChecked(true) 使其选中，也不会取消选择前一个.

If I set a radio button to be selected on the first time, it works fine. But if I unselect it by calling .setChecked(false); then, later even if I try to make it selected by calling setChecked(true) will not unselect the previous one.

    private void radiotype() {
    count = //changed every time.
    LinearLayout llques = (LinearLayout) mview.findViewById(R.id.llrbgRBD);
    RadioGroup group = new RadioGroup(context);
    group.setOrientation(RadioGroup.VERTICAL);
    final RadioButton[] rb = new RadioButton[count];
    List<String[]> ans = getAnswerList.getAns();

    for (int j = 0; j < count; j++) {

        rb[j] = new RadioButton(context);
        rb[j].setVisibility(View.VISIBLE);
        rb[j].setText("`enter code here`hi");
        String a = rb[j].getText().toString();`enter code here`
        Log.e("getAnswerList===a", "getAnswerList===>a" + a);
        Log.e("getAnswerList", "getAnswerList===>" + ans.get(index)[0]);
        if (a.equalsIgnoreCase(ans.get(index)[0])) {
            rb[j].setChecked(true);
        }
        rb[j].setTextColor(Color.BLACK);
        rb[j].setButtonDrawable(R.drawable.custom_radio_button);
        group.addView(rb[j]);
    }
    llques.removeAllViews();
    llques.addView(group);
    group.setOnCheckedChangeListener(new OnCheckedChangeListener() {
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            // checkedId is the RadioButton selected
            //int c = count;
            for(int i=0;i<count;i++){
                rb[i].setChecked(false);
            }
            //
            Log.v("id",""+checkedId);
            for (int i = 0; i < count; i++) {
                if (rb[i].getId() == checkedId){
                    rb[i].setChecked(true);
                } 
            }
        }
    });

推荐答案

我知道这已经很老了，但我也遇到了同样的问题.解决方案是通过 addView() 将 RadioButton 添加到 RadioGroup 之后改变它的状态.我想这也是 BAKUS 在他的示例代码中试图表达的意思.

I know this is rather old, but I just had the same problem. The solution is to change the state of RadioButton after adding it to RadioGroup by addView(). I guess this is also what BAKUS tried to say by his sample code.
