This component requires that you specify a valid TextAppearance attribute

Question

My app theme extends from AppCompat but I want to use Chip dynamically but when I added Chips dynamically app crashing with exception

This component requires that you specify a valid TextAppearance attribute. Update your app theme to inherit from Theme.MaterialComponents (or a descendant).

but when I extend app theme to Material app doesn't crash and filter chips works fine but my problem is I dont want to extend theme from Material because it effects my app UI, how can I use chip in this scenario?

Edit: used bridge, it saves from crashing but when I click chip it does not change appearance of chip that I was clicked

Chip chip = new Chip(getContext());
        ChipDrawable chipDrawable = ChipDrawable.createFromAttributes(getContext(), null, 0, R.style.Widget_MaterialComponents_Chip_Filter);
        chip.setChipDrawable(chipDrawable);
        chip.setCheckable(true);
        chip.setText(itemArrayList.get(i).getName());
        binding.rvReport.addView(chip);

Thanks

You can check the official documentation:

Your app theme should inherit from a Material Components theme.
If you can't change your theme, you can do one of the following:

• Inherit from one of our Material Components Bridge themes
• Continue to inherit from an AppCompat theme and add some new theme attributes to your theme.

For the Chip you can also define the layout as follows:

<com.google.android.material.chip.Chip
    xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/Widget.MaterialComponents.Chip.Filter"
    .../>

and then use this code:

Chip chip =
      (Chip) getLayoutInflater().inflate(R.layout.single_chip_layout, chipGroup, false);
//...
chipGroup.addView(chip);
