i created a custom list with textbox and image. Image should delete row in database sqlite.
in my fragment activity I am using the query method of sqlitedatabase.
cursor = mSqLiteDatabase.rawQuery("SELECT liked_id as _id, liked_presentation_id FROM liked", null);
LikedListCursorAdapter likedListCursorAdapter = new LikedListCursorAdapter(getActivity(), cursor);
lvItems.setAdapter(likedListCursorAdapter);
/////////////my cursoradapter
public class LikedListCursorAdapter extends CursorAdapter {
SQLiteDatabase mSqLiteDatabase;
int idSpeaker,idPresentation;
TextView textViewName, textViewCompany, textViewTitle, textViewDate, textViewAboutReport;
LinearLayout linearLayout;
public static ImageView imageViewStatus;
private DatabaseHelper mDatabaseHelper;
public LikedListCursorAdapter(Context context, Cursor cursor) {
super(context, cursor);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.liked_list, parent, false);
}
@Override
public void bindView(View view, final Context context, final Cursor cursor) {
imageViewStatus = (ImageView) view.findViewById(R.id.imageViewStatus);
textViewTitle = (TextView) view.findViewById(R.id.textViewTitle);
textViewDate = (TextView) view.findViewById(R.id.textViewTime);
idSpeaker = cursor.getInt(cursor.getColumnIndex("_id"));
///////////////delete item
imageViewStatus.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.w("id",String.valueOf(idSpeaker));
mDatabaseHelper = new DatabaseHelper(context);
mSqLiteDatabase = mDatabaseHelper.getWritableDatabase();
mSqLiteDatabase.delete(mDatabaseHelper.TABLE_LIKED,
"liked_id = ?",
new String[] {String.valueOf(idSpeaker)});
cursor.requery();
notifyDataSetChanged();
}
});
however, always remove the last row in the listView. ( position of cursor is last).
I don't know how get current position from listview, when i click. Please, help me
Solution:
I added code for finding position of cursor before setOnClickListener.
final int position = cursor.getPosition();
imageViewStatus.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
int idSpeaker;
mDatabaseHelper = new DatabaseHelper(context);
mSqLiteDatabase = mDatabaseHelper.getWritableDatabase();
/////move to this position
cursor.moveToPosition(position);
idSpeaker = cursor.getInt(cursor.getColumnIndex("liked_id"));
Log.w("getPos",String.valueOf(cursor.getPosition()));
mSqLiteDatabase.delete(mDatabaseHelper.TABLE_LIKED,
"liked_id = ?",
new String[] {String.valueOf(idSpeaker)});
cursor.requery();
notifyDataSetChanged();
}
});
