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"
/>
当前回答
recyclerview.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.HORIZONTAL));
对于垂直线使用LinearLayoutManager。垂直
其他回答
试试这个简单的单行代码
recyclerView.addItemDecoration(new DividerItemDecoration(getContext(),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);
只需在您的RecycleView适配器的项目底部添加x量的边缘。
onCreateViewHolder
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
layoutParams.setMargins(0, 0, 0, 5);
itemView.setLayoutParams(layoutParams);
recyclerview.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.HORIZONTAL));
对于垂直线使用LinearLayoutManager。垂直
只需在项目适配器的末尾添加一个视图:
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#FFFFFF"/>
