Android Dynamically Generated Radio Buttons Not Unchecking Once Setchecked Programmatically

I can't get the below dynamically generated RadioButtons to uncheck when I click on other RadioButton in the same RadioGroup. I have even resorted to writing my own handler that cl

Solution 1:

After struggling for an hour I've found the solution.

Check the RadioButton after adding it to the RadioGroup.

The solution in Kotlin -

val rb = layoutInflater.inflate(R.layout.custom_radiobutton, null) as RadioButton
rb.text = label
rb.isChecked = false

radioGroup.addView(rb)
if(selected) rb.isChecked = true

Solution 2:

The problem is that you are doing things twice. If you already have a radio group that handles toggling and deselecting others. You dont operate on the radiobuttons individually.

Please read the RadioGroup documentation and implement the proper listeners

RadioButton rd = new RadioButton(this); rd = (RadioButton)rg.getChildAt(i);

This makes no sense, first you create a button and then reassign it to a child of RG.

RadioButtonrd= (RadioButton)rg.getChildAt(i);

Should be the correct form.

you should implement this listener on the radiogroup: http://developer.android.com/reference/android/widget/RadioGroup.OnCheckedChangeListener.html

and forget about this part

 rd.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        onRadioButtonClicked(v);
    }
});

Solution 3:

The code I added to try to fix this is confusing everyone; sorry.

The original code is:

RelativeLayout rlaAccessPoints;
RadioGroup rg;

privatevoidPopulateAccessPoints(List<clsAccessPoint> accessPoints){
rg = new RadioGroup(this);

for (clsAccessPoint acp :  accessPoints) {
    RadioButton rd = new RadioButton(this);
    rd.setText(acp.ID + ": " + acp.Name);

    rg.addView(rd);

    if (Settings.AccessPointID.equals(acp.ID)){
        rd.setChecked(true);
    }
}

rlaAccessPoints.addView(rg);
}

This shows the same incorrect behaviour (the RadioButton that I set programatically not being unset when I click on another in the same RadioGroup).

Please refer to this code instead. This is the only applicable code; there is no custom event handlers etc.
