實現RecycleView動態使列表item可以點擊或不可點擊切換

效果

這里講的是第二個button跳轉的Activity，這里和上一篇不同之處在於可以item點擊、item子控件點擊

繼承BaseAdapter

同樣也要繼承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); } }

重寫setItemChildListener()

這里可以實現item子控件的點擊效果，我們僅僅需要baseViewHolderHelper.setItemChildClickListener(adUholder.imageView);這里的參數就是我們讓該控件實現點擊效果。

在Activity中實現GIF中的效果

實現item點擊效果

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

實現item長按效果

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; } });

實現item子控件點擊效果

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

實現item點擊或不可點擊切換

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); } } });
