实现RecyclerView中指定任意item悬浮置顶
效果图如下：
使用方式如下
布局
<com.jokerwan.recyclerviewstickheader.StickyHeaderLayout
android:id="@+id/sh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</com.jokerwan.recyclerviewstickheader.StickyHeaderLayout>
代码
public class StickHeaderActivity extends AppCompatActivity {
private RecyclerView recycler;
private StickyHeaderLayout layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stick_header);
layout = findViewById(R.id.sh_layout);
recycler = findViewById(R.id.recycler);
//设置RecyclerView中需要悬浮置顶的item的position
layout.setShowStickItemPosition(5);
recycler.setLayoutManager(new LinearLayoutManager(this));
recycler.setAdapter(new MyAdapter());
}
}
