我的文本切换器无法正常工作。每次我单击列表上的任何图标（加号图标）...最后一个文本切换器，即列表中最后一个元素的文本切换器，无论您点击哪个加号。所有其他元素列表显示正确。我从数据库中获取了数据，下面的代码是我的自定义适配器代码。dataid 为 id 提供了该位置的元素。
private class SubjectDataList extends ArrayAdapter<String> {
private TextSwitcher mSwitcher;
List<String> names;
Button btnadd;
Typeface newsfont = Typeface.createFromAsset(getContext().getAssets(),
"Adec.ttf");
List<String> dataid = helper.getAllSubjectstsid();
public SubjectDataList(Context context, int textViewResourceId,
List<String> name) {
super(context, textViewResourceId, name);
// TODO Auto-generated constructor stub
names = name;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return helper.getSubjectCount();
}
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
View row = convertView;
if (row == null) {
row = getActivity().getLayoutInflater().inflate(
R.layout.subjectslist, parent, false);
mSwitcher = (TextSwitcher) row.findViewById(R.id.subjcount);
btnadd = (Button) row.findViewById(R.id.addcountbtn);
mSwitcher.setFactory(new ViewFactory() {
public View makeView() {
// TODO Auto-generated method stub
// create new textView and set the properties like
// color, size etc
TextView myText = new TextView(getActivity());
myText.setGravity(Gravity.TOP
| Gravity.CENTER_HORIZONTAL);
myText.setText("0");
myText.setTextSize(36);
myText.setTextColor(Color.GREEN);
myText.setTypeface(newsfont);
return myText;
}
});
// Declare the in and out animations and initialize them
Animation in = AnimationUtils.loadAnimation(getActivity(),
R.anim.slide_in_up);
Animation out = AnimationUtils.loadAnimation(getActivity(),
R.anim.slide_out_up);
// set the animation type of textSwitcher
mSwitcher.setInAnimation(in);
mSwitcher.setOutAnimation(out);
btnadd.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
mSwitcher.setText(String.valueOf(helper
.getAllSubjectstscount(dataid.get(position))));
}
});
TextView text = (TextView) row.findViewById(R.id.subjectname);
text.setTypeface(newsfont);
text.setText(names.get(position));
}
return row;
}
}
这是我获取 id 的函数：
// getting subjects id
public List<String> getAllSubjectstsid() {
List<String> list = new ArrayList<String>();
SQLiteDatabase db = this.getWritableDatabase();
Cursor cur = db.rawQuery("Select " + colsubID + " from " + subjTable
+ " WHERE " + colsubjstudentid + "=" + getPos(), null);
// looping through all rows and adding to list
if (cur.moveToFirst()) {
do {
list.add(cur.getString(0));
} while (cur.moveToNext());
}
// closing connection
cur.close();
db.close();
return list;
}
