I have a SimpleCursorAdapter class, it gets various data from DB and displays in ListView. It implements an onclicklistener that sends a messageGuid String to another activity. All this works fine.
In the row of the ListView i have added a CheckBox and set an onCheckChangeListener to it. At the moment when the checkbox is checked, the messageGuid is always the last one in the cursor.
I need to find a way to get the listview row id of the row which hold the checkbox that has been checked. I can then get the correct cursor row and then in turn the correct messageGuid.
I've commented what i would like within the onCheckedChanged method.
Thanks in advance Matt.
private class MyAdapter extends SimpleCursorAdapter implements OnItemClickListener {
Cursor c;
String messageGuid;
public MyAdapter(Context context, int layout, Cursor c, String[] from,
int[] to) {
super(context, layout, c, from, to);
}
@Override
public
View getView(int position, View convertView, ViewGroup parent) {
Log.e(TAG, "inside myadapter getview for messages");
View v = super.getView(position, convertView, parent);
if(v == null)
return null;
c = (Cursor)getItem(position);
Log.e(TAG, "(Cursor)getItem(position) = " + c + "position = " + position);
v.setTag(c);
//other code removed, not relevant
String messageSender = c.getString(c.getColumnIndex(LoginValidate.C_MESSAGE_SENDER));
String isRepliedTo = c.getString(c.getColumnIndex(LoginValidate.C_MESSAGE_REPLIED));
String isStandAlone = c.getString(c.getColumnIndex(LoginValidate.C_MESSAGE_IS_STANDALONE));
((TextView)v.findViewById(R.id.messagecreatedat)).setText(formattedMessCreatedAt );
((TextView)v.findViewById(R.id.messagetext)).setText(messageText);
((TextView)v.findViewById(R.id.messagesender)).setText(messageSender);
//#003F87 = blue

((TextView)v.findViewById(R.id.messagesender)).setTextColor(Color.parseColor("#003F87"));
((TextView)v.findViewById(R.id.messagetext)).setTextColor(Color.parseColor("#FF0000"));
CheckBox cb = ((CheckBox)v.findViewById(R.id.list_checkbox));
cb.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
//i'd like to something like below where i can specify the row which contains
//the checkbox that has been check and map that to the row in the cursor.
// So if the checkbox in the 2nd row in the listview has been clicked then the messageGuid from the 2nd row in the cursor is found
//c.moveToPosition(the row position of the listview which holds the checkbox that has been clicked );
messageGuid = null;
messageGuid = c.getString(c.getColumnIndex(LoginValidate.C_MESSAGE_GUID));
if(isChecked == true){
Log.e(TAG, "checkBox true and guid = " + messageGuid);
}else{
Log.e(TAG, "checkBox false and guid = " + messageGuid);
}
}
});
return v;
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int pos,
long id) {
Cursor itemCursor = (Cursor) view.getTag();
String messageGuid = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_GUID));
String messageText = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_TEXT));
String messageCreatedAt = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_CREATED_AT));
String messageSender = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_SENDER));
String messageReplied = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_REPLIED));
String messageSeen = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_SEEN));
String isStandAlone = itemCursor.getString(itemCursor.getColumnIndex(LoginValidate.C_MESSAGE_IS_STANDALONE));
Intent i = new Intent(ViewMessagesActivity.this, ReplyToMessageActivity.class);
i.putExtra("guid", messageGuid);
i.putExtra("message", messageText);
i.putExtra("createdat", messageCreatedAt);
i.putExtra("sender", messageSender);
i.putExtra("messagereplied", messageReplied);
i.putExtra("messageseen", messageSeen);
i.putExtra("isstandalone", isStandAlone);
startActivity(i);
}
}// end of adapter
Make position final and use that on onCheckedChanged
or
make cb final
Add before cb.setOnCheckedChangeListener
cb.setTag(position);
And in public void onCheckedChanged you can retrieve the position
int pos = (Integer) cb.getTag();
