我有一个名为
MyRequestFragment
的片段,其中包含一个RecyclerView
,并使用适配器类将数据绑定到RecyclerView
上的onBindViewHolder()
。现在,每个ViewHolder
都有一个按钮。每次点击按钮时,向服务器发送POST
请求并更新值。我的问题是,如果成功响应,则需要隐藏特定ViewHolder
上的按钮。实际问题是runOnUiThread()
不接受onBindViewHolder()
。runOnUiThread(new Runnable() {
public void run() {
}
});
如何在ViewHolder
的创建/绑定方法中调用这个东西。
下面是我完整的onBindViewHolder()
代码,供参考。
@Override
public void onBindViewHolder(MyServiceViewHolder holder, int position) {
final MyServiceBean myServiceBean = serviceList.get(position);
holder.service_name.setText(myServiceBean.getService_name());
holder.last_updated.setText("Job Updated Date : " +myServiceBean.getDate(myServiceBean.getUpdated_at()));
holder.created_date.setText("Job Created Date : " + myServiceBean.getDate(myServiceBean.getCreated_at()));
holder.status.setText(myServiceBean.getStatus());
holder.service_note.setText("Service Note : " + myServiceBean.getService_note());
if (myServiceBean.getService_note().toString().isEmpty())
holder.service_note.setVisibility(View.GONE);
switch (myServiceBean.getStatus().toString().toLowerCase()) {
case "completed":
holder.status.setBackgroundColor(Color.GREEN);
break;
case "on progress":
holder.status.setBackgroundColor(Color.YELLOW);
break;
case "canceled":
holder.status.setBackgroundColor(Color.RED);
break;
case "rejected":
holder.status.setBackgroundColor(Color.RED);
break;
case "accept":
holder.status.setBackgroundColor(Color.BLUE);
break;
default:
holder.status.setBackgroundColor(Color.GRAY);
break;
}
if(myServiceBean.getEst_amount() != null) {
holder.estimation_region.setVisibility(View.VISIBLE);
holder.est_status.setText("Estimation is Available");
holder.btn_approve.setVisibility(View.VISIBLE);
holder.est_amount.setText("Estimation Amount: " + myServiceBean.getEst_amount());
if(myServiceBean.getEst_note() != null)
holder.est_note.setText("Estimation Note: " + myServiceBean.getEst_note());
if(myServiceBean.getEst_presented_by() != null)
holder.est_presented_by.setText("Estimation Prepared By: " + myServiceBean.getEst_presented_by());
if(myServiceBean.getEst_approved_by_customer() == "true"){
holder.btn_approve.setVisibility(View.GONE);
holder.est_status.setText("Estimation Approved on : " + myServiceBean.getEst_approved_date());
}else{
holder.btn_approve.setVisibility(View.VISIBLE);
}
}else{
holder.estimation_region.setVisibility(View.GONE);
holder.est_status.setText("Estimation on Process");
holder.btn_approve.setVisibility(View.GONE);

holder.btn_approve.setOnClickListener(new View.OnClickListener() {
@Override
