Changing Theme

First, you need to set different styles for different color themes - if you want to change theme(setTheme(R.style.id)).

styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">  
    <!-- Customize your theme here. -->  
    <item name="colorPrimary">@color/colorPrimary</item>  
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>  
    <item name="colorAccent">@color/colorAccent</item>  
</style>  
  
<style name="AppThemePurple" parent="Theme.AppCompat.Light.DarkActionBar">  
    <item name="colorPrimary">@color/colorPrimaryPurple</item>  
    <item name="colorPrimaryDark">@color/colorPrimaryDarkPurple</item>  
    <item name="colorAccent">@color/colorAccentPurple</item>  
</style>

MainActivity.java

@Override  
protected void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
  
    // Set theme before setContentView  
    mSharedPreferences = getSharedPreferences(PREF_COLOR, MODE_PRIVATE);  
    int themeSelected = mSharedPreferences.getInt(THEME_SELECTED, R.style.AppTheme);  
    ColorPrefUtil.changeThemeStyle(this, themeSelected);  
  
    setContentView(R.layout.activity_main);  
  
//...  
}

// Get selected colorId from preferences, if null, use default background color(colorPrimary)
selectedBackgroundColorId = mSharedPreferences.getInt(COLOR_SELECTED, R.color.colorPrimary);

// Single view  
mButton = findViewById(R.id.button);  
ColorPrefUtil.changeBackgroundColorOfSingleView(this, mButton, selectedBackgroundColorId);
