我有以下使用交错网格布局管理器的回收器视图:
我想像这样调整交错网格视图的每个项目(如果它是独立的,则最后一个元素全屏显示):
主.java:
staggeredGridLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
superEffectiveRecyclerView.setLayoutManager(staggeredGridLayoutManager);
effectivenessSuperEffectiveAdapter = new EffectivenessRecyclerAdapter(this, effectivenessesSuperEffective);
superEffectiveRecyclerView.setItemAnimator(new DefaultItemAnimator());
superEffectiveRecyclerView.setAdapter(effectivenessSuperEffectiveAdapter);
list_item_type.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:id="@+id/effectiveness_effect"
android:layout_width="33dp"
android:layout_height="25dp"
android:layout_marginTop="4dp"
android:layout_marginBottom="4dp"
android:gravity="center"
android:text="@string/placeholder"
android:textColor="#f000"
android:textSize="14sp" />
<TextView
android:id="@+id/effectiveness_name"
android:layout_width="81dp"
android:layout_height="25dp"
android:layout_marginTop="4dp"
android:layout_marginBottom="4dp"
android:gravity="center"
android:text="@string/placeholder"
android:textColor="#f000"
android:textSize="14sp" />
</LinearLayout>
content_main.xml:
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/super_efective_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" />
我怎样才能做到这一点?
编辑:显然,设置:
StaggeredGridLayoutManager.LayoutParams layoutParams = (StaggeredGridLayoutManager.LayoutParams) holder.itemView.getLayoutParams();
if(Objects.nonNull(layoutParams)){
if (getItemCount() % 3 == 1 && position == getItemCount() - 1) {
layoutParams.setFullSpan(true);
}
}
在视图持有人的结果是:
但是,这不是我想要的,我只想要最后一个元素全屏
