android为RadioButton单独添加checked监听事件
final RadioButton red_radio = (RadioButton) findViewById(R.id.red_radio);final RadioButton gray_radio = (RadioButton) findViewById(R.id.gray_radio);gray_radio.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {red_radio.setChecked(false);}});
