How to use spinner int value to programatically add views?

Here is the relevant code:

mspin=(Spinner) findViewById(R.id.spinner);
Integer[] items = new Integer[]{1,2,3,4,5,6,7,8,9,10};
ArrayAdapter<Integer> adapter = new ArrayAdapter<>(this,android.R.layout.simple_spinner_item, items);
mspin.setAdapter(adapter);

RG = (RadioGroup) findViewById(R.id.radioGroup);

mspin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        int TYPE = Integer.parseInt(mspin.getSelectedItem().toString());

        setRadios(TYPE);

    }

    public void onNothingSelected(AdapterView<?> parent) {

    }
});

public void setRadios(int mk) {

    for(int i=0; i==mk; i++){

        RadioButton bg = new RadioButton(this);
        bg.setText("hello, this is mk");

        RG.addView(bg);

    }

}

I am trying to get an int value from a spinner and then add that many RadioButtons to the RadioGruop RG. However, when I run the code it does nothing when I click on a spinner value.

try this method:

public void setRadios(int number) {

    for (int row = 0; row < 1; row++) { //add to first row
        RadioGroup rg = new RadioGroup(this);
        rg.setOrientation(LinearLayout.HORIZONTAL);

        for (int i = 1; i <= number; i++) {
            RadioButton rdbtn = new RadioButton(this);
            rdbtn.setId((row * 2) + i);
            rdbtn.setText("Radio " + rdbtn.getId());
            rg.addView(rdbtn);
        }
        ((ViewGroup) findViewById(R.id.radiogroup)).addView(rg);
    }

  }

in XML:

<RadioGroup
android:id="@+id/radiogroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical" />

you are not adding radiobutton to the viewgroup

You have mistake in your for loop change this for(int i=0; i==mk; i++) to this for(int i=0; i<=mk; i++) and also you can simplify how you get int Type to int Type = items[position]

int TYPE = Integer.parseInt(mspin.getSelectedItem().toString());

this is wrong try the below code. it will worked .

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

                int TYPE=Integer.parseInt(adapter.getItem(position).toString());

                setRadios(TYPE);

            }
