我有2 Radio Groups。每个人有2 Radio buttons。如何获得所选id的{{1}} radio group？
答案 0 :(得分：0)
将RadioGroup添加到RadioGroup，然后从方法ID获取所选的onCheckedChanged() int selectedRadioGroupId = 0;
// Group 1
radioGroup1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
selectedRadioGroupId = radioGroup.getId();
switch (checkedId) {
case R.id.button1:
// Do something
Toast.makeText(getApplicationContext(), radioButton1.getText() + " clicked", Toast.LENGTH_SHORT).show();
break;
case R.id.button2:
// Do something
Toast.makeText(getApplicationContext(), radioButton2.getText() + " clicked", Toast.LENGTH_SHORT).show();
break;
}
}
});
// Group 2
radioGroup2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup radioGroup, int checkedId) {
selectedRadioGroupId = radioGroup.getId();
switch (checkedId) {
case R.id.button3:
// Do something
Toast.makeText(getApplicationContext(), radioButton3.getText() + " clicked", Toast.LENGTH_SHORT).show();
break;
case R.id.button4:
// Do something
Toast.makeText(getApplicationContext(), radioButton4.getText() + " clicked", Toast.LENGTH_SHORT).show();
break;
}
}
});
。
试试这个：
let snapshot: DataSnapshot = self.dataSource.items[indexPath.row]
