I have a ListView that is backed by a SimpleCursorAdapter. I'd like to be able to filter the list like you would a contacts list, just by typing, and I came across the textFilterEnabled() Problem is, I couldn't see how to get it to work with a SimpleCursorAdapter. Is this even possible?

Since the query that comprises my ListView basically gets the rowID, name, and a third column from my databases's table, I want to be able to filter the cursor based on the partial value of the name column. However, I am uncertain of whether I can do this directly from runQuery without expanding my DB class since I want to filter the existing cursor, or will I have to create a new query function in my DB class that partially searches my name column, and if so, how would I go about creating the query statement while using the CharSequence constraint argument in runQuery?I am also concerned about the performance issues associated with trying to run multiple queries based on partial text since the DB table in question has about 1300-1400 rows. In other words, would I run into a bottleneck trying to filter the cursor?

Note: bookmarkStore.getCursor() returns an unmanaged cursor from a sqlite database containing the columns from bookmarksColumns.

My app is mainly made up of a listview linked to a simplecursoradapter (custom one I might add) which in turn uses a cursor which gets the data fed in from a dbadapter class.
using the dbadapter class I can retrieve data using the rawquery and query methods no problem. However I am trying to allow the user to enter a month in and then the app will scroll to that month in the list , instead of the user having to scroll through several months to get there.
This is where I am struggling, I have tried to move to the position within the original cursor and then calling changeCursor from the simplecursoradapter with no luck and tried using the listview with smothscrolltoposition again with no luck and even tried to notifydatachangedset (probably got that named wrong) and then within the custom simplecursoradater try and move to it but that does not work either.
I am making a Glossary of legal terms and I would like to be able to narrow the results in the list by typing in an edit box, I have tried finding a solution but none of them have worked for me.
View 1 Replies View RelatedI have a Cursor that returns rows I use with a SimpleCursorAdapter to populate a ListView. I would like to filter some of the rows so they don't get displayed in my ListView. I use the data from the rows elsewhere in my Activity so I don't want to change my SQL to filter them with a WHERE clause. What is the best way to keep a row from being displaying in my ListView? Ideally I would check a column in my row and then only add rows to the ListView that satisfy a condition.

View 2 Replies View RelatedBut now I'm on 2.1, it doesn't do anything of the sort.
e.g. let's say i had sent out a text stating; "Hi John, I will be at yours next week - you can email me at berty@bassett.com if you need me to bring anything"
so a few days later I'd start a new text. By the time I'd wrote "Hi" the system would offer me the next word as "John" - it had kind of learned what it thought I might want to say next. This was incredibly useful when entering email addresses into form pages.
Now, when I type "Hi", it offers stupid suggestions like "Hit, High, Hill" and other completely unrelated junk.
If I enable predictive texts, it auto fixes words that don't need auto fixing. I sent a text to my sister saying "lolzalot" and by the time I realised what had gone on, it had instead replaced my word with "locally"
Why is this new way of doing things so poor compared to the old 1.6 way? Or at least, how can I get it back to being like it should be.
Currently I'm using the default filter but I would like to be able to make it so I can ignore some letters at the beginning of the strings in the adapter. I've had a look at the public methods available on Multi Auto Complete Text View but can't find anything on how to pass my own filter to it. Any idea how to do this?
View 2 Replies View RelatedI made a app to block some junk messages. That app would delete the messages from the senders specified in the ban list. That app works in a way, but has some defects, as follows, 1. Sometime it just doesn't work, missing the new message to delete. 2. Even if it works deleting the message, a notification sound and message still occur. Therefore, could any improvement be made to 100% block messages without any notifications? Please check the codes below, and see what I can do.

I gather information about certain events from a webpage, and then I want to display all events in a list using the above layout for each event. My current approach is to have a LinearLayout as parent and then adding each event as a row.
Problem number one is to add the layout to each event (the number of events is varying). I.e., I want to dynamically inflate this layout for each event. I also don't want the text to be hard coded into the layout (as above) but added at runtime. I don't know how to do this. I have tried something like the following without any success.
LinearLayout eventView = (LinearLayout) findViewById(R.layout.event);
parentView.addView(eventView);
Problem number two is then to add these layouts to the parent view group and display it on the screen. When I try to do this using parent.addView(child), the program crashes at runtime and I can't figure out why.
It's kind of hard to describe the specific problem, since I'm new to GUI-programming on Android and I'm sort of programming by trial and error right now. Anyway, if you are able to help me with some of the problems it would be greatly appreciated. Linus
EDIT:
The problem now is adding text dynamically to the TextViews. I try this:
TextView dest = (TextView) findViewById(R.id.destination);dest.setText("myText");
only to discover that dest is null. Any ideas why and how to fix this?
EDIT 2:
I have narrowed the problem even more, but I really don't understand its nature. This is the trouble-method: Code...
it somehow works (even though the events are displayed in reverse order). Anyone knows what's going on here?
I am looking for an app that would automatically send a text message based on a GPS location. The reason for this app is because I am a vanpool driver and it would be great if I could notify my riders when I am getting close to their house so that they are waiting for me when I pull up. Much better than having to honk my horn and then wait!
