Lease Add Radio Button Groups For Free

To group radio buttons, they should have the same value for the name attribute. This allows us to select only one radio button at once and apply the required attribute to the whole group.

By default, the android RadioButton will be in OFF (Unchecked) state. We can change the default state of RadioButton by using android:checked attribute. In case, if we want to change the state of RadioButton to ON (Checked), then we need to set android:checked = true in our XML layout file.

You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes.

To define the click event handler for a button, add the android:onClick attribute to the <RadioButton> element in your XML layout. The value for this attribute must be the name of the method you want to call in response to a click event. The Activity hosting the layout must then implement the corresponding method.

Radio buttons allow a user to select a single option among multiple options. You can set the Choice Value of each option, for each button, as well as group these buttons by giving them the same Group Name.So, you add three radio buttons and make sure all three of them have the same group name: "Attending".

For creating dynamic RadioButton, we need to use android. view. ViewGroup. LayoutParams which configures the width and height of views and implements setOnCheckedChangeListener() method of RadioGroup class.

Select all the buttons you want to group by pressing CTRL and the button. Right click on one of the buttons and select properties. In the ButtonGroup of the Properties, click on the down arrow. Your selection of button groups should appear.
