实现RecycleView动态使列表item可以点击或不可点击切换

效果

这里讲的是第二个button跳转的Activity，这里和上一篇不同之处在于可以item点击、item子控件点击

继承BaseAdapter

同样也要继承BaseAdapter

public class ADUadapter extends BaseAdapter<ChatModel> { public Context context; protected ADUholder holder; public ADUadapter(Context context) { super(); this.context = context; } @Override protected void setItemChildListener(BaseViewHolder viewHolder) { super.setItemChildListener(viewHolder); if (viewHolder instanceof ADUholder){ ADUholder adUholder = (ADUholder) viewHolder; baseViewHolderHelper.setItemChildClickListener(adUholder.imageView); } } @Override protected BaseViewHolder addViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_list, parent, false); return new ADUholder(view); } @Override protected void fillData(RecyclerView.ViewHolder holder, final int position, final ChatModel item) { this.holder = (ADUholder) holder; this.holder.title.setText(item.name); this.holder.name.setText(item.mMsg); } }

重写setItemChildListener()

这里可以实现item子控件的点击效果，我们仅仅需要baseViewHolderHelper.setItemChildClickListener(adUholder.imageView);这里的参数就是我们让该控件实现点击效果。

在Activity中实现GIF中的效果

实现item点击效果

adUadapter.setOnItemClickListener(new BaseViewHolder.OnItemClickListener() { @Override public void onItemClick(View view, int position) { Toast.makeText(UpdataItemActivity.this, "position: " + position, Toast.LENGTH_SHORT).show(); } });

实现item长按效果

adUadapter.setOnLongItemClickListener(new BaseViewHolder.OnLongItemClickListener() { @Override public boolean onLongItemClick(View view, int position) { String title = adUadapter.getItem(position).name; Toast.makeText(UpdataItemActivity.this, title + ",position: " + position, Toast.LENGTH_SHORT).show(); return true; } });

实现item子控件点击效果

adUadapter.setOnChildItemClickListener(new BaseViewHolderHelper.OnChildItemClickListener() { @Override public void onChildItemClick(View view, int position) { String title = adUadapter.getItem(position).name; Toast.makeText(UpdataItemActivity.this, title + "，你点了图片,position: " + position, Toast.LENGTH_SHORT).show(); } });

实现item点击或不可点击切换

rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup radioGroup, int i) { if (i == R.id.radioButton) { adUadapter.getViewHolder().setItemable(true, true); } else if (i == R.id.radioButton2) { adUadapter.getViewHolder().setItemable(false, false); } } });

好了，在此附上github源码，喜欢的请start、fork。 https://github.com/DyncKathline/TestRecyclerView
