ItemDecoration

这是一个简单易用的分割线库，可以使用默认值，也可以很方便的设置样式。目前只支持纯色分割线的设置，不支持Drawable

引用

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.lany192:ItemDecoration:1.18'
}

使用

LinearLayoutManager

recyclerView.addItemDecoration(new LinearItemDecoration(LinearLayoutManager.HORIZONTAL)
                .setColor(Color.RED)
                .setWidth(4));

GridLayoutManager

recyclerView.addItemDecoration(new GridItemDecoration()
        .setSpanCount(manager.getSpanCount())
        .setShowBorder(false)
        .setWidth(4)
        .setColor(Color.RED));

不同item使用不同的分割线，复现getDivider(int itemPosition)

    recyclerView.addItemDecoration(new ItemDecoration() {

        @Override
        public Divider getDivider(int itemPosition) {
            Divider divider = null;
            if ((itemPosition >= 1 && itemPosition <= 6) || itemPosition == 9 || itemPosition == 10) {
                divider = new Divider()
                        .setBottom(Color.BLACK, 6)
                        ;
            } else if (itemPosition == 0 || itemPosition == 7 || itemPosition == 8) {
                divider = new Divider()
                        .setRight(Color.BLACK, 6)
                        .setBottom(Color.BLACK, 6)
                        ;
            } else if (itemPosition > 10 && itemPosition < 22) {
                switch ((itemPosition - 10) % 4) {
                    case 1:
                    case 2:
                    case 3:
                        divider = new Divider()
                                .setRight(Color.BLACK, 6)
                                .setBottom(Color.BLACK, 6)
                                ;
                        break;
                    case 0:
                        divider = new Divider()
                                .setBottom(Color.BLACK, 6)
                                ;
                        break;
                    default:
                        break;
                }
            }
            return divider;
        }

    });
