有時當我想在單選按鈕中選擇選項時,單選按鈕出現問題,我可以選擇兩個收音機但是有時候它是正確的,因爲它必須工作。單選按鈕在android中出錯
這裏是我的代碼:
span.replace(0,0,getText(R.string.ForeSingleChoice));
new DynamicViews().makeNormalContent(getApplicationContext(),span,linearLayout,16,16,16,16,16.0f);
span.clear();
radioGroup = new DynamicViews().makeRadioGroup(getApplicationContext(),linearLayout);
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),-1);
new DynamicViews().makeRadioButton(getApplicationContext(),radioGroup,getString(R.string.Choice_Q2Mathematicsop4_2),-1);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
switch (checkedId)
{
case 5: goToNextLevel= true ;
break;
default: goToNextLevel = false;
break;
}
}
});
DynamicViews makeRadioButton:
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 makeRadioGroup:
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;
}
我的應用程序由很多單選按鈕組成,這是我製作這些單選按鈕的方法,有什麼問題?這是一個錯誤?
我建議你使用'radioGroup'而不是使用多個'radioButtons'! – sam
@sam我做了一個radiogroup,並添加了4個單選按鈕 –
