我想知道检查哪个RadioButton
执行操作。
但这不起作用。在日志中我有ID -1
mradioGroup = (RadioGroup) rootView.findViewById(R.id.choix_plateforme);
mradioGroupt = (RadioButton) rootView.findViewById(R.id.ps4);
mradioGroupa = (RadioButton) rootView.findViewById(R.id.xbox);
mradioGroupw = (RadioButton) rootView.findViewById(R.id.pc);
int selectedId = mradioGroup.getCheckedRadioButtonId();
Log.d(getClass().getName(), "Plateforme_Choix = " + selectedId);
// find which radioButton is checked by id
if(mradioGroupt.isChecked()) {
string_plateforme = "one";
} else if(mradioGroupa.isChecked()) {
string_plateforme = "two";;
} else if (mradioGroupw.isChecked()){
string_plateforme = "oops";
}
else {
string_plateforme = "wrong";
}
我的if
声明也不起作用。
<RadioGroup
android:id="@+id/choix_plateforme"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal">
<RadioButton
android:id="@+id/ps4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Playstation 4" />
<RadioButton
android:id="@+id/xbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="XBOX ONE" />
<RadioButton
android:id="@+id/pc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ordinateur" />
</RadioGroup>
你能告诉我哪里错了吗?我不想要新的代码,但如果可以,请向我解释我的错误。
答案 0 :(得分:1)
尝试设置OnCheckedChangeListener
更改侦听器:
radiogroup.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(RadioGroup group, int checkedId)
{
switch(checkedId)
{
case R.id.ps4:
Log.d(getClass().getName(), "Plateforme_Choix =ps4");
break;
case R.id.xbox:
Log.d(getClass().getName(), "Plateforme_Choix =xbox");
break;
case R.id.pc:
Log.d(getClass().getName(), "Plateforme_Choix =pc");
break;
}
}
});
