How can i achieve that ?
thanx in advance
You can use broadcast receiver to notify fragment
OR create callback method to notify fragment
1]create interface and implement it on your fragment
2] pass its object in adapter and use that object to notify fragment
//code example
public interface ICallback {
void onClick();
}
// HistoryAdapter
#Override
public void bindView(View view, final Context context, final Cursor cursor) {
//your code
button.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v) {
//your code
iCallbackInstance.onClick();
}
});
}
EDIT
// In HistoryAdapter
public class HistoryAdapter extends CursorAdapter {
ICallback iCallbackInstance;
public HistoryAdapter(Context context, Cursor c, int flags, ICallback instance;) {
super(context, c, flags);
mainActivity = (MainActivity) context;
historyDialogue = new HistoryDialogue();
iCallbackInstance = instance;
}
}
//HistoryDialogue
Use
adapter = new HistoryAdapter(getActivity(), c, 0, HistoryDialogue.this)
instead of
adapter = new HistoryAdapter(getActivity(), c, 0)

}
this is complete code..Listview is success before search function.
please help me
For this you can use like for check a work in first and last name.
cursorLoader = new CursorLoader(getActivity(),
FriendinfoTable.CONTENT_URI, null, FIRST_NAME+" like '%"+search_work+"%' or "+SECOND_NAME+" like '%"+search_work+"%'", null, null);
I have a very specific problem. I'm creating a word list app that basically lets me enter some words and their meanings and stores them in an SQLite database and then it shows them back to me. I've made my own content provider to handle all these interactions. I store the words in one table and the definitions in another table and these two tables are linked together through the books' unique id. I'm also using a CursorLoader and a CursorAdapter to populate my listView in my MainActivity. Now my problem is when I get the list of the words that I have in my database, some of the words have more than one definition and I have to query against the database as I'm drawing each list item in my listView to find the definitions and put them on the list. This has caused my listView to stutter. I've even tried to use AsyncTask but I don't want to start a new thread every time a word is getting added to my listView at runtime. Is there any efficient, right way to do this?
This is my CursorAdapter class where I believe is the source of the problem.

You have only one adapter instance and hence one position member variable. The variable is reassigned for each call to newView(). If you want to store the index of a list item, put it in the view holder instead of adapter.
Good day, please could somebody help me find out what's wrong with my code. I am probably missing something. Nothing is displayed from my CursorAdapter.
Have been struggling with here for some time now.
Any help will be highly appreciated!!

The problem might be here. Its just an assumption. Sorry if I am wrong.
#Override
public int getCount() {
return count;
}
What is the value of count here. I don't find any place where you have passed the value for count.So my assumption is that, the default value for int is returned here (i.e count=0) and hence you don't find any data in your GridView.
Could you check that and comment back.
