单击RadioButton“ A”切换RadioButton“ B” RecyclerView

Question

I have a RecyclerView that displays a list of RadioButtons of countries, to let the user choose his country. I don't want more than on Item clicked, so I've wrote this OnCheckListener in the onBindView method of the adapter, but whenever I click a RadioButton, several other buttons toggles with it.

    @Override
    public void onBindViewHolder(final com.example.ameer.ta7adialma3rifa.adapters.CountriesAdapter.ViewHolder holder, final int position) {
        String name = mData.get(position).getName();
        int imgId = mData.get(position).getImageId();
        holder.radioButton.setText(name);
        holder.flagImageView.setImageResource(imgId);
        holder.radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
                RadioButton button = (RadioButton) compoundButton;
                if (!button.getText().equals(mData.get(position).getName())){
                    button.setChecked(false);
                }
                if (runnable != null){
                    runnable.run();
                }
                runnable = new Runnable() {
                    @Override
                    public void run() {
                        holder.radioButton.setChecked(false);
                    }
                };
            }
        });
    }

You should put your radio buttons in a radio group. this way just one of them is being chosen. and I don't know why are using runnable to set the radio button checked! I hope this helps you.
