Can't change Radio Button color on Android

Question

I'm using Android Studio. I need to change the color of the Radio Button, after changing the Button Tint Color value to the one I need it works on the preview, but whenever I launch the app on a device the button is the standard green/blue-ish color.

Is this some kind of device API level issue? If so, is it possible to change the color for older devices?

Answer 1

If you want to change the color, but not change colorControlActivated and colorControlNormal for the entire app, you can override your apptheme just for the radio button by creating a new style:

<android.support.v7.widget.AppCompatRadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_alignParentEnd="true"
    android:theme="@style/RadioButtonTheme"
    android:id="@+id/radioButton"/>



<style name="RadioButtonTheme" parent="@style/AppTheme">
    <item name="colorControlActivated">@color/colorAccent</item>
    <item name="colorControlNormal">@color/colorPrimaryDark</item>
</style>

I have done this way:

Screenshot

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context=".MainActivity"
    tools:showIn="@layout/app_bar_main">

    <RadioGroup
        android:id="@+id/radioGroup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">


    </RadioGroup>

</RelativeLayout>

MainActivity.java

public class MainActivity extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);


        RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radioGroup);

        /**
         * First Radio Buttonn
         */
        RadioButton radioButtonAndroid = (RadioButton) getLayoutInflater().inflate(R.layout.custom_radiobutton, null);
        radioButtonAndroid.setText("Hello Android");
        radioGroup.addView(radioButtonAndroid);

        /**
         * Second Radio Buttonn
         */
        RadioButton radioButtonIos = (RadioButton) getLayoutInflater().inflate(R.layout.custom_radiobutton, null);
        radioButtonIos.setText("Hello Ios");
        radioGroup.addView(radioButtonIos);
    }
}

custom_radiobutton.xml

<?xml version="1.0" encoding="utf-8"?>
<RadioButton xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:buttonTint="@color/colorPrimary"
    android:text="">

</RadioButton>

Hope this will help you.
