如何在Android RecyclerView中添加分隔线?

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"
    />

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());

你需要添加下一行…

mRecyclerView.addItemDecoration(new DividerItemDecoration(getContext(), DividerItemDecoration.VERTICAL));

芬兰湾的科特林版:

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

下面是一个简单的自定义分割线(垂直分割线/ 1dp高度/黑色)的代码:

假设你有支持库:

compile "com.android.support:recyclerview-v7:25.1.1"

java代码

    DividerItemDecoration divider = new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.VERTICAL);
    divider.setDrawable(ContextCompat.getDrawable(getBaseContext(), R.drawable.my_custom_divider));
    recyclerView.addItemDecoration(divider);

然后custom_divide .xml文件示例:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="1dp" />
    <solid android:color="@android:color/black" />
</shape>

我认为这是最简单的方法

mDividerItemDecoration = new DividerItemDecoration(recyclerView.getContext(),
                DividerItemDecoration.VERTICAL);
// or DividerItemDecoration.HORIZONTALL
        mDividerItemDecoration.setDrawable(getDrawable(R.drawable.myshape));
        recyclerView.addItemDecoration(mDividerItemDecoration);

注意:myshape可以是你想要做分隔的高度的矩形
