代码实现
创建外层RecyclerView
// 在布局文件中定义外层RecyclerView
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/outerRecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
// 在Activity或Fragment中获取外层RecyclerView并设置布局管理器
RecyclerView outerRecyclerView = findViewById(R.id.outerRecyclerView);
outerRecyclerView.setLayoutManager(new LinearLayoutManager(this));
创建内层RecyclerView
// 在外层RecyclerView的Adapter中创建内层RecyclerView
@Override
public void onBindViewHolder(@NonNull OuterAdapter.ViewHolder holder, int position) {
InnerAdapter innerAdapter = new InnerAdapter(data.get(position).getInnerData());
holder.innerRecyclerView.setLayoutManager(new LinearLayoutManager(context));
holder.innerRecyclerView.setAdapter(innerAdapter);
}
设置内层RecyclerView高度
// 在内层RecyclerView的Adapter中设置高度
@Override
public void onBindViewHolder(@NonNull InnerAdapter.ViewHolder holder, int position) {
ViewGroup.LayoutParams layoutParams = holder.itemView.getLayoutParams();
layoutParams.height = 200; // 设置高度为200px
holder.itemView.setLayoutParams(layoutParams);
}
设置外层RecyclerView高度
// 在Activity或Fragment中设置外层RecyclerView高度
RecyclerView outerRecyclerView = findViewById(R.id.outerRecyclerView);
ViewGroup.LayoutParams layoutParams = outerRecyclerView.getLayoutParams();
layoutParams.height = 500; // 设置高度为500px
outerRecyclerView.setLayoutParams(layoutParams);
通过以上步骤,你可以实现Android RecyclerView嵌套RecyclerView,并且设置高度使其显示完全。希望对你有帮助!
