java - 此组件要求您指定有效的 TextAppearance 属性

Question

我的应用主题从 AppCompat 扩展而来，但我想动态使用 Chip，但是当我动态添加 Chips 时，应用程序因异常而崩溃

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

但是当我将应用程序主题扩展到 Material 应用程序时不会崩溃并且过滤芯片工作正常但我的问题是我不想从 Material 扩展主题因为它会影响我的应用程序用户界面，我如何在这种情况下使用芯片？

编辑: 使用桥接器，它可以避免崩溃，但是当我点击芯片时，它不会改变我被点击的芯片的外观

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);

谢谢

Answer 1

您可以查看 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.

对于芯片你也可以定义布局如下:

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

然后使用这段代码:

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