将自定义 chipDrawable 背景设置为 Chip

Question

我想为 Chip 设置自定义可绘制背景，就像那样 chip.setBackgroundDrawable(context.getResources().getDrawable(R.drawable.bg_cutom_drawable));

但不是working.It报错

java.lang.UnsupportedOperationException: Do not set the background resource; Chip manages its own background drawable.

需要 chipDrawable。如何为其创建 chipDrawable。我尝试但无法找到解决方案。请建议我，我将不胜感激。

Answer 1

不要使用 android:background 属性。它会被忽略，因为 Chip 管理自己的背景 Drawable chip document

Answer 2

如果你想改变背景颜色，你可以尝试：

ChipDrawable chipDrawable = (ChipDrawable)chip.getChipDrawable();
chipDrawable.setChipBackgroundColorResource(R.color.colorPrimary);

Answer 3

如果有人在对话框中使用 material 芯片并因上述相同错误而崩溃，那么您需要从样式中删除对话框集的背景属性。

Answer 4

Using this code you can generate multicolor chip.

将此代码添加到 oncreate() 或函数中的任意位置

// "i" is integer value and it will be unique for every chip. In my case I have put in chip in FOR loop that why "i" is there

Chip chip = (Chip) LayoutInflater.from(getActivity()).inflate(R.layout.item_content_lang_chip, null);
                chip.setText(contentLangModels.get(i).getContentDisplay());
                chip.setId(i);
chip.setChipBackgroundColor(buildColorStateList(getActivity(),"#1e61d5","#2e2e37"));


chipGrpContentType.addView(chip);

Add below function in your activity

 public ColorStateList buildColorStateList(Context context, String pressedColorAttr, String defaultColorAttr){
        int pressedColor = Color.parseColor(pressedColorAttr);
        int defaultColor = Color.parseColor(defaultColorAttr);

        return new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{} // this should be empty to make default color as we want
                }, new int[]{
                pressedColor,
                defaultColor
        }
        );
    }
