浏览这篇旧帖子时,发现我做了类似的事情,可能会有所帮助:
public class FormatCursorAdapter extends SimpleCursorAdapter {
protected int[] mFormats;
public static final int FORMAT_TEXT=0;
public static final int FORMAT_CURRENCY=1;
public static final int FORMAT_DATE=2;
public FormatCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int[] formats, int flags) {
super(context, layout, c, from, to, flags);
mFormats = formats;
ViewBinder viewBinder = new ViewBinder() {
@Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
int formatType = mFormats[columnIndex-1];
switch (formatType) {
case FORMAT_CURRENCY:
NumberFormat nf = NumberFormat.getCurrencyInstance();
nf.setMaximumFractionDigits(2);
((TextView)view).setText(nf.format(cursor.getDouble(columnIndex)));
return true;
case FORMAT_DATE:
DateFormat df = SimpleDateFormat.getDateTimeInstance();
((TextView)view).setText(df.format(new Date(cursor.getLong(columnIndex))));
return true;
}
return false;
}
};
setViewBinder(viewBinder);
}
}
使用方法:
String[] fromColumns = {
Table.COLUMN_TITLE,
Table.COLUMN_AMOUNT,
Table.COLUMN_DATE};
int[] toViews = {
R.id.tvTitle,
R.id.tvAmount,
R.id.tvDate};
int[] formatViews = {
FormatCursorAdapter.FORMAT_TEXT,
FormatCursorAdapter.FORMAT_CURRENCY,
FormatCursorAdapter.FORMAT_DATE};
mAdapter=new FormatCursorAdapter(getContext(),R.layout.item_operation,cursor,
fromOpsColumns,toOpsViews,formatViews,0);
mListView.setAdapter(mOpsAdapter);
希望这能帮助到任何需要的人!
aColumnIndex
是游标中可以找到数据的列
。我使用了Cursor.getColumnIndex
进行比较。 - theblang
