Creating RadioButtons programmatically

Question

I want to create a series of radio buttons which correspond to an array of strings within an Android app. The radio buttons should toggle content to be displayed from the array. How do I do this?

Answer 1

You must add the radio buttons to a RadioGroup and then the RadioGroup to the layout

I miss some information like what is submit, but your code should look like:

private void createRadioButton() {     final RadioButton[] rb = new RadioButton[5];     RadioGroup rg = new RadioGroup(this); //create the RadioGroup     rg.setOrientation(RadioGroup.HORIZONTAL);//or RadioGroup.VERTICAL     for(int i=0; i<5; i++){         rb[i]  = new RadioButton(this);         rg.addView(rb[i]); //the RadioButtons are added to the radioGroup instead of the layout         rb[i].setText("Test");     }     ll.addView(rg);//you add the whole RadioGroup to the layout     ll.addView(submit);      submit.setOnClickListener(new View.OnClickListener() {         public void onClick(View v) {             for(int i = 0; i < 5; i++) {                  rg.removeView(rb[i]);//now the RadioButtons are in the RadioGroup             }               ll.removeView(submit);             Questions();         }     });    } 

Another code for dynamically creating the radiobutton

<TableRow>     <RadioGroup         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:orientation="vertical"         android:id="@+id/radiobuttons">      </RadioGroup> </TableRow> 

Code:

public void makeRadioButtons(Vector tmpVector, int i, LinearLayout.LayoutParams lp) {      RadioButton rb = new RadioButton(this);      rb.setText((String) tmpVector.elementAt(i));      //rg is private member of class which refers to the radio group which I find      //by id.      rg.addView(rb, 0, lp);  }
