我知道为什么当我选择一个单选按钮时这会导致我的应用程序崩溃？

我已经导入了android.Widget.RadioGroup.OnCheckedchangelistener,我也试过了

new RadioGroup.OnCheckedchangelistener()

这是类似帖子的解决方案.

代码是(添加了logcat)：

RadioGroup ringtone_radio_group = (RadioGroup)findVIEwByID(R.ID.ringtone_radio_group);    ringtone_radio_group.setonCheckedchangelistener(new OnCheckedchangelistener()    {        @OverrIDe        public voID onCheckedChanged(RadioGroup group, int checkedID)        {            Toast.makeText(getApplicationContext(), "checked ID = " + checkedID, Toast.LENGTH_SHORT).show();        }    });

布局是：

解决方法:

从XML中的每个Radiobuttons中删除androID：onClick =“onRadiobuttonClick”.您应该处理在RadioGroup上设置的OnCheckedchangelistener中的Radiobuttons的选择.

如果在选择特定的Radiobutton时需要进行特殊处理,可以在onCheckedChanged回调中使用switch语句 – checkedID参数是所选Radiobutton的androID：ID值(如果清除选择,则为-1).
