Answer 1

我已经通过改变解决了：

SharedPreferences preferences = getSharedPreferences("PREFERENCE", 0);

到此：

SharedPreferences preferences = getSharedPreferences("help", 0);

在onClick方法中使用Switch：

@Override
public void onClick(View v) {
    Intent intent = null;
    int selectedId = radioLaGroup.getCheckedRadioButtonId();
    switch(selectedId) {
        case R.id.frenchRadio:
            intent = new Intent(this, French.class);
            break;
        case R.id.italianRadio:
            intent = new Intent(this, Italian.class);
            break;
        case R.id.englishRadio:
            intent = new Intent(this, French.class);
            break;
    }
    if(intent != null) {
        startActivity(intent);
    }   
}

RadioButton实现默认活动？
