我正在开发一个android应用程序，我正在使用RecyclerView。我需要在RecyclerView中添加一个分隔符。 我试着加上-
recyclerView.addItemDecoration(new
DividerItemDecoration(getActivity(),
DividerItemDecoration.VERTICAL_LIST));
下面是我的XML代码-
<android.support.v7.widget.RecyclerView
android:id="@+id/drawerList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
/>

recyclerview.addItemDecoration(DividerItemDecoration(this, LinearLayoutManager.VERTICAL))

如果你想同时使用水平和垂直分隔符:
Define horizontal & vertical divider drawables: horizontal_divider.xml <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <size android:height="1dip" /> <solid android:color="#22000000" /> </shape> vertical_divider.xml <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" > <size android:width="1dip" /> <solid android:color="#22000000" /> </shape> Add this code segment below: DividerItemDecoration verticalDecoration = new DividerItemDecoration(recyclerview.getContext(), DividerItemDecoration.HORIZONTAL); Drawable verticalDivider = ContextCompat.getDrawable(getActivity(), R.drawable.vertical_divider); verticalDecoration.setDrawable(verticalDivider); recyclerview.addItemDecoration(verticalDecoration); DividerItemDecoration horizontalDecoration = new DividerItemDecoration(recyclerview.getContext(), DividerItemDecoration.VERTICAL); Drawable horizontalDivider = ContextCompat.getDrawable(getActivity(), R.drawable.horizontal_divider); horizontalDecoration.setDrawable(horizontalDivider); recyclerview.addItemDecoration(horizontalDecoration);
所以这可能不是正确的方式，但我只是添加了一个视图到RecyclerView的单项视图(因为我不认为有一个内置的函数)，像这样:
<View
android:layout_width="fill_parent"
android:layout_height="@dimen/activity_divider_line_margin"
android:layout_alignParentBottom="true"
android:background="@color/tasklist_menu_dividerline_grey" />
这意味着每一项都有一行在底部填充。我把它做成1dp高，背景#111111。这也给了它一种“3D”效果。
我认为你是在使用Fragments来实现RecyclerView
在创建RecyclerView和LayoutManager对象后，只需添加这些行
DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(recyclerView.getContext(),
DividerItemDecoration.VERTICAL);
recyclerView.addItemDecoration(dividerItemDecoration);
就是这样！
它支持水平和垂直方向。
yqritc的RecyclerView-FlexibleDivider使它成为一个内衬。首先把这个添加到你的build.gradle:
compile 'com.yqritc:recyclerview-flexibledivider:1.4.0' // requires jcenter()
现在你可以在你设置recyclerView的适配器的地方配置和添加一个分配器:
recyclerView.setAdapter(myAdapter);
recyclerView.addItemDecoration(new HorizontalDividerItemDecoration.Builder(this).color(Color.RED).sizeResId(R.dimen.divider).marginResId(R.dimen.leftmargin, R.dimen.rightmargin).build());
试试这个简单的单行代码
recyclerView.addItemDecoration(new DividerItemDecoration(getContext(),LinearLayoutManager.VERTICAL));
