我试图在ListView中点击按钮更新ListView数据但是我收到以下错误：
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

我正在尝试更新ListView中按钮单击时的TextView值，但问题是有时它会更新正确的TextView，有时它会在同一个ListView中更新错误的TextView。有关此问题的任何帮助将不胜感激。谢谢提前。
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;
}

使用OnItemClickListener的{{1}}
然后你将得到项目和位置来执行你的任务。

@Xgamer：您的textView可能未正确放置在XML文件中。请检查一下。

如果要从适配器刷新lisview，那么 而不是notifyDataSetChanged（）;
调用AdapterClassName.this.notifyDataSetChanged（）;
