Question

I want to add a Chip view to ChipGroup in my project but always I get below error

My code in Activity

 for (int i = 0; i < names.size(); i++) {
      Chip chip = new Chip(getApplicationContext());
      chip.setText(names.get(i));
      chip.setId(i);
      chipGroup.addView(chip);
    }

and Error is

java.lang.IllegalArgumentException: The style on this component requires your app theme to be Theme.MaterialComponents (or a descendant).

My app theme

 <style name="AppTheme" parent="Theme.MaterialComponents.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>

As shown in the code above my theme is right!

Answer 1

After a while I found that need to pass Activity to Chip instead pass context

The code is right below.

 Chip chip = new Chip(this);
