这里我的Total ItemCount为8，我的按钮位置从0开始

现在，当我单击0定位按钮时，所有其他1,2,3,4 ...定位按钮都应禁用

操作方法

我只想使用“无按钮”复选框，无切换按钮

预先感谢

将currentPos变量设置为按钮的onClick中的单击位置，然后调用notifyDatasetChanged。还要在onBindViewHolder中添加以下代码，以基于currentPos启用/禁用按钮

myHolder.btn.setEnabled(position == currentPos)

如果要首先启用所有按钮，则currentPos的初始值必须为-1（值小于0） 还要添加额外的支票，例如

myHolder.btn.setEnabled(position == currentPos || currentPos == -1)

最终代码为

public class complaintAdapter extends 
RecyclerView.Adapter<RecyclerView.ViewHolder> {
private Context context;
String hello, status, type;
private LayoutInflater inflater;
public String service, typeid;
String result_reso;
List<DataComplaint> data= Collections.emptyList();
DataComplaint current;
int currentPos=-1;
MyHolder holder;

public complaintAdapter(Context context, List<DataComplaint> data, String service_id, String type_id){
    this.context=context;
    inflater= LayoutInflater.from(context);
    this.data=data;
    this.service = service_id;
    this.typeid = type_id;
}
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = inflater.inflate( R.layout.container_complaint, viewGroup, false );
        holder = new MyHolder( view );
        Log.e( TAG, "holder = " + typeid );
    return holder;
}




public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, final int i) {

    final MyHolder myHolder= (MyHolder) viewHolder;
    final DataComplaint current=data.get(i);

   myHolder.btn.setEnabled(i== currentPos || currentPos == -1)

    myHolder.textcomplaint.setText(current.complaint);
    myHolder.textaddress.setText("Reason: " + current.address);
    myHolder.textType.setText("Client   : " + current.complaint_type);
    myHolder.textplace.setText("Location: " + current.location);
    myHolder.textticket.setText( current.ticket );
    final int value = getItemCount();
    if(typeid.equals( "history" )){

    }
    //  myHolder.textPrice.setTextColor( ContextCompat.getColor(context, R.color.colorAccent));

答案 1 :(得分：0)

在Onclicklistner的{​​{1}}中，尝试调用一个传递被点击的buttons的位置值的函数。

函数应如下所示：-

button

然后在ArrayList<Bollean) buttonStates = new ArrayList(); void disbleButtonsNotEqualToPos(int pos){ for(int i=0;i<list.size();i++) { if(i!=pos) buttonStates.add(false); } notifyDataSetChanged(); //reflect changes } 中使用列表（将其添加到按钮中）如下：-

onBindViewHolder()

答案 2 :(得分：0)

重写recycleview适配器中的getViewType（）方法。仅返回位置，删除任何其他代码。
