Xml - Adding custom radio buttons in android

To add custom radio buttons in Android, you can create a custom layout for your radio button and then use that layout with the RadioButton widget. Here's a step-by-step guide:

  1. Create a Custom Layout for the Radio Button: Define a layout XML file for your custom radio button. For example, you could create a file named custom_radio_button.xml in your res/layout directory:
<!-- res/layout/custom_radio_button.xml --> <?xml version="1.0" encoding="utf-8"?> <RadioButton xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/radio_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:button="@drawable/custom_radio_button_selector" android:paddingStart="8dp" <!-- Add padding or customize other attributes --> android:paddingEnd="8dp"/>
  1. Create Selector Drawable: You need to create a selector drawable for your custom radio button. This drawable will define the states (e.g., checked, unchecked) and the corresponding drawables or colors to use for each state. For example, create a file named custom_radio_button_selector.xml in your res/drawable directory:
<!-- res/drawable/custom_radio_button_selector.xml --> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/ic_radio_button_checked" android:state_checked="true"/> <item android:drawable="@drawable/ic_radio_button_unchecked"/> </selector>

In this example, ic_radio_button_checked and ic_radio_button_unchecked are drawable resources for the checked and unchecked states, respectively.

  1. Use the Custom Radio Button: Now, you can use your custom radio button layout wherever you need a radio button in your XML layout files:
<!-- Example usage in a layout file --> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <include layout="@layout/custom_radio_button" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Option 1" /> </LinearLayout>
  1. Handle Selection: To handle the selection of your custom radio button in your Java/Kotlin code, you can set an OnCheckedChangeListener to the RadioButton instance:
RadioButton radioButton = findViewById(R.id.radio_button); radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // Handle radio button selection } });

That's it! You've created and used a custom radio button in your Android application. Adjust the layout and selector drawable according to your design requirements.
