Android RadioButton in Android Studio
RADIOBUTTON EXAMPLE IN ANDROID STUDIO in XML layout in Android Studio can be used to allow the user to make a single choice from multiple options. Here’s how to use it:
- Add the RadioButton to your layout XML file.
- Set the layout_width and layout_height properties to control the size of the RadioButton. You can set them to wrap_content to make the RadioButton the same size as its text, or set them to a specific value in pixels or dp to control the size.
- Set the text property to specify the text that should be displayed next to the RadioButton, to describe the option.
- To group multiple RadioButtons together so that only one can be selected at a time, you can wrap them in a RadioGroup element:
- You can also set additional properties, such as textColor to control the color of the text, and checked to specify whether the RadioButton should be selected by default.
Here’s an example of a RadioButton in XML layout in Android Studio that displays text next to a RadioButton and sets its size to match the size of the text:
<?xml version="1.0" encoding="utf-8"?> <RadioGroup android:layout_width="wrap_content" android:layout_height="wrap_content"> <RadioButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Option 1" /> <RadioButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Option 2" /> </RadioGroup>
Note: To handle the selected RadioButton in your code, you can use the getCheckedRadioButtonId() method on the RadioGroup object to get the ID of the selected RadioButton. For example:
RadioGroup myRadioGroup = findViewById(R.id.my_radio_group); int selectedId = myRadioGroup.getCheckedRadioButtonId(); RadioButton selectedRadioButton = findViewById(selectedId); String selectedOption = selectedRadioButton.getText().toString();
That’s it! You can now run your app and see the RadioButtons displayed in the layout. The user can select one of the RadioButtons, and you can access the selected RadioButton in your code.
