问题描述

我正在尝试在ListView中单击按钮时更新ListView数据，但是出现以下错误： 

4193-4193/kanix.highrise.com.highrise W/View﹕ requestLayout() improperly called by android.widget.TextView{69deba1 V.ED.... ......ID 381,134-423,163 #7f0a00e0 app:id/tvCQty} during layout: running second layout pass

我正在尝试在ListView中单击按钮时更新TextView值，但问题是有时它会更新正确的TextView，有时会在同一ListView中更新错误的TextView。有关此问题的任何帮助将不胜感激。

我的GetView方法是这样的： 

  @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            View view = convertView;

            if (view == null) {
                lInflater = (LayoutInflater) ctx .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = lInflater.inflate(R.layout.style_workcompletion
                        , parent, false);



                holder = new ViewHolder();

                holder.tvTask = (TextView) view.findViewById(R.id.tvTask);
                holder.tvPS=(TextView)view.findViewById(R.id.tvPS);
                holder.tvCQty=(TextView)view.findViewById(R.id.tvCQty);


                holder.tvCompQty= (TextView) view.findViewById(R.id.tvCompQty )   ;
                holder.tvTQty=(TextView)view.findViewById(R.id.tvTQty);
                holder.etCompQty  = (EditText) view.findViewById(R.id.etCompQty );
                holder.btnRefreshWoQty =(Button)view.findViewById(R.id.btnRefreshWOQty);
                //SelectQuantity=(EditText)findViewById(R.id.etSQuantity);
                view.setTag(holder);

                //  tvAQuantity.setText(p.getAQ());
                //   etQuantity.setTag(position);

            }
            else {

                holder=(ViewHolder)view.getTag();
            }
            holder.btnRefreshWoQty.setOnClickListener(null) ;// you need to set listener to null.

            p = getProduct(position);
            if(p!=null) {
                if (holder.tvCompQty != null) {

               Log.d("all details",p.getTotalQty()+"-"+p.getCumulative_Qty()+"-"+p.getCompQty());

                    holder.tvTask.setText(p.getTASKNM() );
                    holder.tvPS.setText(p.getPS());
                    holder.tvCQty.setText(p.getCumulative_Qty());
                    holder.tvCompQty.setText(p.getCompQty());
                    holder.tvTQty.setText(p.getTotalQty());
                    holder.etCompQty.setText("0.0");



                }
            }

            final int     posi=position;

            holder.btnRefreshWoQty.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    RelativeLayout  rl = (RelativeLayout)v.getParent();

                    holder.tvCompQty = (TextView) rl .findViewById(R.id.tvCompQty );
                    holder.tvCQty = (TextView) rl .findViewById(R.id.tvCQty);
                    holder.tvTQty = (TextView) rl .findViewById(R.id.tvTQty);
                    holder.etCompQty=(EditText)rl.findViewById(R.id.etCompQty );

                    if((Float.parseFloat (holder.tvTQty.getText().toString())-Float.parseFloat (holder.tvCQty.getText().toString()))>=Float.parseFloat (holder.etCompQty.getText().toString()))
                    {
                        p = getProduct(posi);
                        p.setCompQty(holder.etCompQty.getText().toString());

                        lstItems .get(position).setCompQty(holder.etCompQty.getText().toString());
                        Log.d("compQty",p.getCompQty());
                        Log.d("cumQty",p.getCumulative_Qty( ));
                        Log.d("tQty",p.getTotalQty());
                        notifyDataSetChanged();
                    }
                    else
                    {
                        Toast.makeText(myactivity,"Quantity should be less than pending quantity!",Toast.LENGTH_SHORT).show();

                    }
                }
            });






            //  CheckBox cbBuy = (CheckBox) view.findViewById(R.id.checkbox);
            //cbBuy.setOnCheckedChangeListener(myCheckChangList);
            //  cbBuy.setTag(position);
            //  cbBuy.setChecked(p.selected);
            return view;
        }

如果要从适配器刷新lisview，则代替notifyDataSetChanged（）;。

调用AdapterClassName.this.notifyDataSetChanged（）;
