android RadioGroup 初始化注意事项

//正确的设置流程
private RadioGroup mDualMode = (RadioGroup)findViewById(R.id.dualmode);

if(type != null && type.equals("RUIM")){
            
    Log.i(TAG,"________________________________________CDMA RUIM");
    mDualMode.check(R.id.dualmode_2);
}else{
    Log.i(TAG,"________________________________________GSM SIM");
    mDualMode.check(R.id.dualmode_1);
}                
mDualMode.setOnCheckedChangeListener(this);

//错误的设置流程
private RadioGroup mDualMode = (RadioGroup)findViewById(R.id.dualmode);

mDualMode.setOnCheckedChangeListener(this);

if(type != null && type.equals("RUIM")){
            
    Log.i(TAG,"________________________________________CDMA RUIM");
    mDualMode.check(R.id.dualmode_2);
}else{
    Log.i(TAG,"________________________________________GSM SIM");
    mDualMode.check(R.id.dualmode_1);
}                

总结：当设置事件setOnCheckedChangeListener写在设置check的前会导致初始化混乱。
