RadioGroup with two columns which have ten RadioButtons

Solution
You can simulate that `RadioGroup` to make it look like you have only one. For example you have `rg1` and `rg2`(`RadioGroups` with orientation set to `vertical`(the two columns)). To setup those `RadioGroups`:
rg1 = (RadioGroup) findViewById(R.id.radioGroup1);
rg2 = (RadioGroup) findViewById(R.id.radioGroup2);
rg1.clearCheck(); // this is so we can start fresh, with no selection on both RadioGroups
rg2.clearCheck();
rg1.setOnCheckedChangeListener(listener1);
rg2.setOnCheckedChangeListener(listener2);
To select only one `RadioButton` in those `RadioGroups` the listeners above will be:
private OnCheckedChangeListener listener1 = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId != -1) {
rg2.setOnCheckedChangeListener(null); // remove the listener before clearing so we don't throw that stackoverflow exception(like Vladimir Volodin pointed out)
rg2.clearCheck(); // clear the second RadioGroup!
rg2.setOnCheckedChangeListener(listener2); //reset the listener
Log.e("XXX2", "do the work");
}
}
};
private OnCheckedChangeListener listener2 = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
if (checkedId != -1) {
rg1.setOnCheckedChangeListener(null);
rg1.clearCheck();
rg1.setOnCheckedChangeListener(listener1);
Log.e("XXX2", "do the work");
}
}
};
To get the checked `RadioButton` from the `RadioGroups` you could do:
int chkId1 = rg1.getCheckedRadioButtonId();
int chkId2 = rg2.getCheckedRadioButtonId();
int realCheck = chkId1 == -1 ? chkId2 : chkId1;
If you use the `check()` method of the `RadioGroup` you have to remember to call `clearCheck()` on the other `Radiogroup`.
Problem
I have a `RadioGroup` and I want to align buttons next to each other in two columns and five rows and I am unable to achieve it. Things I have tried: - `RelativeLayout` -> Outside `RadioGroup` -> Inside `RadioGroup`. All `RadioButtons` are selected, but I want only one to be selected. - `RadioGroup` : orientation - Span, stretchcolumns - `TableRow` - `TableLayout` Please let me know how create one `RadioGroup` and have two columns and many `RadioButtons` within.
