图片我在DB的图像,我把它放到我的GridView的这段代码:GridView控件与数据库
public void setNotes()
{
String[] columns = {NotesDbAdapt.KEY_ID, NotesDbAdapt.KEY_IMG, NotesDbAdapt.KEY_NAME, NotesDbAdapt.KEY_DATE, NotesDbAdapt.KEY_TIME};
String table = NotesDbAdapt.NOTES_TABLE;
Cursor c = MainNote.mDB.getHandle().query(table, columns, null, null, null, null, null);
startManagingCursor(c);
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
R.layout.file_dialog_row,
c,
new String[] {NotesDbAdapt.KEY_IMG, NotesDbAdapt.KEY_NAME, NotesDbAdapt.KEY_DATE, NotesDbAdapt.KEY_TIME},
new int[] {R.id.img, R.id.txt, R.id.date, R.id.time});
adapter.setViewBinder(new NotesBinder());
gridview.setAdapter(adapter);
}
一切ok,但却滚动很慢,生涩。似乎每次都从DB获取信息。如何解决它?
