老规矩,先看图:
布局文件:
TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="规格"
android:textColor="#ff999999"
android:textSize="15sp"
android:layout_marginTop="15dp"
android:layout_marginLeft="15dp"
/>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
>
</android.support.v7.widget.RecyclerView>
代码实现:
FlowLayoutManager flowLayoutManager = new FlowLayoutManager();
//设置每一个item间距
recyclerView.addItemDecoration(new SpaceItemDecoration(10);
recyclerView.setLayoutManager(flowLayoutManager);
specAdapter = new MyGoodsSpecAdapter(getActivity())
recyclerView.setAdapter(specAdapter );
**
