有时当我想在单选按钮中选择选项时,单选按钮有问题,我可以选择两个无线电但是有时候它是正确的默认方式它必须工作。
这是我的代码:
public RadioButton makeRadioButton(Context context, RadioGroup radioGroup, String text, int Id) {
RadioButton radioButton = new RadioButton(context);
LinearLayout.LayoutParams Params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
radioButton.setBackgroundResource(R.drawable.backgroundbetweenradios);
radioButton.setLayoutParams(Params);
radioButton.setPadding(dpToPx(8,context) , dpToPx(8,context) , dpToPx(8,context) , dpToPx(8,context));
radioButton.setId(Id);
radioButton.setText(text);
radioButton.setTextColor(Color.BLACK);
radioGroup.addView(radioButton);
return radioButton;
}
DynamicViews makeRadioButton:
public RadioGroup makeRadioGroup(Context context, LinearLayout linearLayout) {
RadioGroup radioGroup = new RadioGroup(context);
LinearLayout.LayoutParams Params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
radioGroup.setLayoutParams(Params);
radioGroup.setOrientation(LinearLayout.VERTICAL);
CardView cardView = new CardView(context);
cardView.setCardBackgroundColor(Color.WHITE);
cardView.setCardElevation(8.0f);
Params.setMargins(dpToPx(16,context) , dpToPx(16,context) , dpToPx(16,context) , dpToPx(16,context));
cardView.setLayoutParams(Params);
cardView.addView(radioGroup);
linearLayout.addView(cardView);
return radioGroup;
}
DynamicViews makeRadioGroup:
{{1}}
我的应用程序由很多单选按钮组成,这是我制作这些单选按钮的方法,有什么问题?这是一个错误吗?

在onCreate()
CompoundButton.OnCheckedChangeListener listener = new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
rbtn1.setChecked(yesrbtn == buttonView);
rbtn2.setChecked(norbtn == buttonView);
....
}
}
};
rbtn1.setOnCheckedChangeListener(listener);
rbtn2.setOnCheckedChangeListener(listener);
这样做是为了确保不允许无线电按钮具有2个或更多选择

您是否尝试过为每个单选按钮指定唯一ID?
new DynamicViews().makeRadioButton(getApplicationContext(),radioGroup,getString(R.string.Choice_Q2Mathematicsop1_2),1);
new DynamicViews().makeRadioButton(getApplicationContext(),radioGroup,getString(R.string.Choice_Q2Mathematicsop2_2),5);
new DynamicViews().makeRadioButton(getApplicationContext(),radioGroup,getString(R.string.Choice_Q2Mathematicsop3_2),2);
new DynamicViews().makeRadioButton(getApplicationContext(),radioGroup,getString(R.string.Choice_Q2Mathematicsop4_2),3);
