difficulty image

您好，我正在开发一款游戏。但是我无法修复我的游戏难度。如何让困难模式按钮运行？我希望当我选中 RadioButton 时，我在主菜单中的任何播放按钮都会更改布局 Activity 。帮助

btnOk.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        int selectedid = mMode.getCheckedRadioButtonId();
        if(selectedid == R.id.radiohard){
            Intent intentMain = new Intent(Settings.this, HardMode.class);
            startActivity(intentMain);
            Log.i("Content ", " Main layout ");
        }
            popupWindow.dismiss();
        }
    });
