I'm trying to add some radio buttons to a Navigation Drawer.
This is what I've been trying so far :
activity_main_drawer.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:showIn="navigation_view">



    <group

        android:id="@+id/radio_button_group"

        android:checkableBehavior="single"

        android:visible="true">

        <item

            android:id="@+id/radio_buttonX-axis"

            android:icon="@drawable/ic_x_axis"

            android:title="Show x-axis"

            app:actionViewClass="android.widget.RadioButton"/>

        <item

            android:id="@+id/radio_buttonY-axis"

            android:icon="@drawable/ic_y_axis"

            android:title="Show y-axis"

            app:actionViewClass="android.widget.RadioButton" />

        <item

            android:id="@+id/radio_buttonZ-axis"

            android:icon="@drawable/ic_z_axis"

            android:title="Show z-axis"

            app:actionViewClass="android.widget.RadioButton" />

    </group>

</menu>

Reference this and this answers.

Method 1: Add Radio Group after the Radio Buttons are created

Is this even possible?

int ids = {R.id.radio_buttonX_axis, R.id.radio_buttonY_axis, R.id.radio_buttonZ_axis};

RadioGroup radioGroup = new RadioGroup(navigationView.getContext());

radioGroup.setOrientation(RadioGroup.VERTICAL);

for (int id : ids) {

    MenuItem menuItem = navigationView.getMenu().findItem(id);

    RadioButton radioButton = (RadioButton) menuItem.getActionView();

    radioGroup.addView(radioButton);

}

But it gives an error of :

The specified child already has a parent. You must call removeView()
on the child's parent first.

But I wasn't able to figure out how to call it

Method 2: Add Radio Buttons to Navigation Drawer dynamically

navigationView.getMenu().removeGroup(R.id.radio_button_group);

RadioGroup radioGroup = new RadioGroup(navigationView.getContext());

for (int i = 0; i < 3; i++) {

    RadioButton radioButton = new RadioButton(navigationView.getContext());

    radioButton.setText("Show X - Axis");

    radioGroup.addView(radioButton);

}

navigationView.addView(radioGroup);

But it doesn't works as expected (See Image).

I tried to add the radioGroup to Menu, but I couldn't figure out how to do it either. This is what I was trying to do :

Menu testMenu = navigationView.getMenu();

testMenu.add(R.id.radio_button_group, testMenu.findItem(R.id.radio_buttonX_axis).getActionView().getId(), 1, "Show X - Axis");

But it just adds an option to NavigationDrawer, not a radio button.

Method 3

This is just hypothetical, I don't know if it's even possible or not.

1. Copy the instances of all radio_buttons and store in some RadioButton array.


2. Remove Group (as done in Method 2)


3. Create a RadioGroup, and add all the RadioButtons to it.


4. Add this new RadioGroup to navigationView
   

But none has been helpful. Please tell me what to do?

You can add a radiobuttons in the menu drawer. First create an xml layout (radio_button.xml):

 <RadioGroup android:layout_width="wrap_content"

   android:layout_height="wrap_content"

   xmlns:android="http://schemas.android.com/apk/res/android">



    <RadioButton

        android:id="@+id/radioButton"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:text="RadioButton" />



    <RadioButton

        android:id="@+id/radioButton2"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_weight="1"

        android:text="RadioButton" />

</RadioGroup>

Then add it to the drawer:

  <item android:title="Radios">

    <menu>

        <item

            app:actionLayout="@layout/radio_button"

            android:id="@+id/nav_radios"

            android:title=""

            />



    </menu>

 </item>
