我将视图寻呼机作为行放在列表视图中，并且在滚动列表视图时想要更新视图寻呼机的内容。我试过=
@Override
public int getCount() {
// return PAGE_NUM;
Log.e("intCount8888: "," = " +intCount );
notifyDataSetChanged();
return intCount;
}
我在getView（）
中也调用了列表适配器上的notifyDataSetChange @Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
Holder holder = null;
if (row == null)
{
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new Holder();
holder.txt_Descid = (TextView) row.findViewById(R.id.textDescid);
holder.txtTitle = (TextView) row.findViewById(R.id.txt_Desc);
holder.txtInitialLetter = (TextView) row.findViewById(R.id.txt_InitialLetter);
holder.txtRemark = (TextView) row.findViewById(R.id.textRemark);
holder.imgBtn_Rework = (ImageView) row.findViewById(R.id.imgButtonRework);
holder.imgBtn_FollowUp = (ImageView) row.findViewById(R.id.imgButtonFoloowUp);
holder.imgBtn_RateEquipMent = (ImageView) row.findViewById(R.id.imgButtonRateEquipment);
holder.imgBtn_Camera = (ImageView) row.findViewById(R.id.imgButtonCamera);
holder.imgBtn_Audio = (ImageView) row.findViewById(R.id.imgButtonAudio);
holder.imgBtn_FollowInspector = (ImageView) row.findViewById(R.id.imgButtonFollowInspector);
holder.viewPager = (ViewPager) row.findViewById(R.id.Image_ViewPagers);
holder.viewPager.setPageMargin(-50);
holder.viewPager.setHorizontalFadingEdgeEnabled(true);
holder.viewPager.setFadingEdgeLength(20);
holder.viewPager.setClipToPadding(false);
holder.viewPager.setPadding(-5, 0, 0, 0);
MyPagerAdapter adapter = new MyPagerAdapter(getContext());
holder.viewPager.setAdapter(adapter);
holder.viewPager.setCurrentItem(0);
adapter.notifyDataSetChanged();
//holder.viewPager.getAdapter().notifyDataSetChanged();
row.setTag(holder);
} else {
holder = (Holder) row.getTag();
}
All_Post all_Post = data.get(position);
holder.txt_Descid.setText(Integer.toString(all_Post.getID()));
String strTextDescId = holder.txt_Descid.getText().toString().trim();
Log.e("strTextDescId ", " = " + strTextDescId);
getActivityId(strTextDescId);
getActivityObjectId_Count();
holder.txtTitle.setText(all_Post.getName());
String strTxtTitle = holder.txtTitle.getText().toString().trim();
Log.e("strTxtTitle ", " = " + strTxtTitle);
holder.txtInitialLetter.setText(all_Post.getInitName());
holder.txtRemark.setText(all_Post.getStrDesc());
holder.imgBtn_Rework.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.e("Button click ", "event is fire");
}
});
但是收到错误

先谢谢
答案 0 :(得分：3)
Notifydatasetchange（）用于告知适配器在数据发生更改时更新其列表。你不要在getView（）或getCount（）中调用它。如果已从列表视图中添加或删除任何列表项，则必须调用notifyDataSetChanged（）。
滚动lisview时，getView（）方法会使视图膨胀。而getCount（）方法只返回ListView包含的列表项的数量。
