With what? All you've shown is code (which has not been tagged correctly so makes it appear pieces are missing), but have said nothing about what is happening, what is supposed to happen, any exceptions that are being thrown, whether you've used the debugger and what it showed, etc.
To borrow a phrase, help us to help you.

Hey guys  ,
I am currently having a bit of an issue with my app i'm building. It starts up fine but everytime I have it go to the keywordsearch activity it crashes. I looked at logcat and it seems to be an issue with the listview.setadapter on row 49 but I cant figure out why? I have looked on here for an answer but I just can't make it work. If you guys could help me that would be awesome.

The exception guides you straight to the location where this error is coming from:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference
As per your code, there can be two ways to fix this,
keywordlist = findViewById(R.id.keywordlist);
Either, check that this keywordlist view has been inflated in the activity. Otherwise, if you are deep down in the hierarchy, try accessing this view from the view that your control is currently inside — happens with inflated views and layouts.
There are several other things that can go wrong, so best hands are still yours to find the bug, try debugging and seeing why is that object null.

Thank you for your response! I was wondering if you could elaborate on this?

what do you mean by the view that my control is inside and how would that work?
Thank you for looking into it. I really appreciate it.

I shared a link for a thread that talks about a common problem in Android programming. The function findViewById() tries to capture the View from the current context or the scope, which is mostly the Activity. When you try to find the view by the ID of, keywordlist, runtime will try to find the view inside the current context, most likely, Activity you are currently inside.
For example, you just inflated the activity_main layout, but you are having the ListView defined inside another layout file,
<ListView
android:id="@+id/keywordlist"
android:layout_width="match_parent"
android:layout_height="match_parent">
</ListView>
This is one of the problems that you might be facing, because your View is not even inflated — unless your activity_main tries to inflate this view internally, which I am not sure of as you did not show the code for that activity.
I did not run the code, or analyze it completely, but most likely there are two things that might go wrong here,
- The view does not get inflated, or it not found in the context you are trying to look under.
- You are not using the correct ID of the element.
Also check if the ID is being used correctly and for the view you are expecting to be there. Debug, debug, debug. Also try to listen on a click listener of the view and find the ID or parents of that to check the hierarchy of the elements.

Thank you,
I will try these options and see if that fixes it.

Hello to all,
I'm looking for somebody to write app with in AS. All data/project is ready just programming left to be done. Since I'm only 'a year experienced' beginner, I wish to work with somebody more advanced in java-android programming. There is a big chance of success so we can work as co-creators in coming projects too.

Can you please explain what type of project it is? Actually I have experience in building projects for some particular domains. Please let me know about the industry and other details that you can share.

Hi,
I have a lot of database text files arranged inside folders and subfolders. I want to restrict the files from accessing externally from the app. So asset/ raw folder is the best option and each file size is less than 50kb. And in asset folder the arrangement is similar to file system and in raw folder its based on id's. So i opt for asset folder.
The selection of the database file is done by the user. So a search dialog window for browsing the file would be the better option. But i don't find any sample code for accessing a asset file system using dialog window. Is it possible?.
Thanks
Nikhil.

Thanks for the reply.
Actually I need a sample code for accessing a file in asset folder with the help of file browsing dialog window not this.
Anyway i dropped the plan, instead of file browsing dialog window, listview will be a better option. Files and folders inside the asset folder can be displayed in ListView and user can select what they need.

Those two things are mutually exclusive. Whether you have a dialog or not, you still need a container (e.g., ListView) for the filenames.

Hello all. From out of 10 dialogs, I need one of the dialogs to start with landscape orientation. No other activity, fragment and dialog will be started with landscape orientation except this one dialog.
I have absolutely no idea how do I make this happen? Do I create some custom control ?
Thanks for any input.

I have an Android application where customers can purchase and put orders
Every customer can put order and I just have one `JSON` file in the `PHP` server to collect the orders from different customers
The problem is if one customer puts his/her order, the `JSON` file shall be locked in order to prevent collision and if it is locked, how can another customer put order at the exact same time?
To solve this issue, and for test, I decided to have a folder in the server where every customer (who is going to put an order) can put his unique ID there (uploading a text file with the name of the customer's ID) and I just read that folder to see who has put any order and then I delete the file which was uploaded by the customer indicating he/she has just put an order to be ready from another order from that customer
(every customer creates a folder with his/her unique ID name to put detailed list of his/her orders and this is handled by PHP code)
It works fine but does not seem to be a true manner from performance point of view
Any suggestion?
