I've create an application using JSON. It shows the list of some items from one link whatever i used in Codes. In my application i've using 2 layouts for display the items. First layout doesn't have any problem. But, when i go to next layout the result of first layout also show here and overrides the second layout's contents. I'm using android:list for list that. Can anyone clarify this doubt? Thanks in Advance.
Make sure your ID on your Lists are different. This could cause the problem.

Actually, I am working on RecyclerView that shows some details along with images and all data comes from a database.
In my RecyclerView, I have used three diffs layout and each layout is used according to data coming from the database that means if only one image comes from database then one_image.xml layout comes to play, if two then two_imag.xml layout comes to play and if more than three then the third layout I am using.
My apps working fine for some extents but when i am trying to scroll down further, it get crashed. I come to know that the problem is on OnCreateViewHolder, meaning it doesn't get called when I go down further in Recycler View.
I searched alots on google but nothing work for me. Is it possible to call OnCreateViewHolder every time or some other way to solve this problem?
Thanks in advance
Sounds like the best option would be to use one layout file that has all three image views but just default them to visibility "gone" so they dont take up space. Then when you need to use them, set them to visibility "visible" when you are creating your viewholder.
Without seeing any actual code it hard to be more specific.
I am trying to create a fragment and inside that i want to create multiple textviews whoose text is set from the data retreived from the database(mysql).
And also i want to have the feature "refresh" by which the textviews are updated with recent data from the database.Iam trying to do that but iam not getting enough idea how to do it as iam new to android programming.
Please help me with this. thank you in advance and any suggestions are acceptable.
i.e
I have database of a person and i want to get his name and address from that,then in my activity i want to create a fragment that displays a name and address in separate textboxes and if address or name exceeds some length then i can press "more" to see left information
Consider using a ListView to populate data from the database, and a SwiperRefreshLayout to refresh it. Check these links for more info :
SwipeRefreshLayout
ListViews
The answer depends on what your app will do.
If you have a fixed number of TextViews, and the number won't change in the future or depending on the answer to the database query, you could simply stick to normal TextViews; if the number changes, I suggest using ListViews or ExpandableListViews.
Regarding the layout, you can create a normal layout using AndroidStudio's layout designer, and then inflate it to your view.
For the refresh, you can add a button that calls the method in which you fill the textviews/listviews.
Actually your question is too broad: if you want a more specific answer, you should edit it asking what you really need.
I am trying to create a screen where I get two items from SharedPreferences and display them to the screen, and then display a list via an adapter.
What I am not sure about is how to structure the layout xml file for this. Any suggestions how to do that?
Thanks!
You can have the main layout with a listview. Then you can have a sub layout for each row of your list. This row layout, let's call it row_layout.xml may have two text areas if your items are text or it may have a text area and a checkbox button if that's what you want. Basically, whatever you want to display in a single row of your list.
Read up a tutorial, here's one: http://www.vogella.de/articles/AndroidListView/article.html
Take a look # MergeAdapter, you can also create a view only listitem and add these item as header to the list
I am not sure what you mean. Are you asking for examples of layouts with two textviews that can be updated via sharedprefs, with a ListView in the activity? Or just suggestions? An easy way to get started would be to use the Eclipse Android plugin that has a layout designer in it. Here is a tutorial on how to use it http://mobile.tutsplus.com/tutorials/android/android-layout/ Its pretty easy and straight forward.
Good Morning All,
I am creating an application to display List of applications with their data usage.
I want my list to look similar to Traffic Counter Pro on android Market
I have also added the print-screen on my box.net as SOF does allow me to upload image
So Can someone direct me how to create ListView like this?
My second Question related to this how to create a tab style Activity.
Two examples that helped me a lot:
http://www.codemobiles.com/forum/viewtopic.php?t=876
and
http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html
i hope they are usefull to you.
You have to use custom ListView to embed images and format texts as given in the listview.
check out this example or this example or this example or even this example that gives you good understanding on listviews.
Good luck.
This is ListView which items consist of 4 Views objects, look through the tutorial of how to create ListViews and through the tutorial of how to create TabActivitys. And also use links suggested by #parag.
If you observe the screen shot carefully you can identify that group of these fields are available as list item.
They are
Application Icon
Application Name
Data Uploaded
Data Downloaded
Total Data Usage
So you have to create a layout with these fields as children with appropriate position and Use this custom layout as child layout for ListView.
I hope it may help you.
Hey all,
I know that this question has been asked many times in this forum itself. But I am not able to get a working solution out of any one of them.
My problem is that I need to create a list view with images. The content is static. Eg: Lets say i need to display 5 rows of data and I have 5 images to go with these rows. All i need to do is to display them in a list format!
Simple right??
Thanks in advance!
Hey nice to see somebody facing the same problem as I did.
Here is the very simple solution for that.
Make a ArrayList add your five elements in that named COUNTRIES.
create one list_item.xml file with one ImageView named imageview and one TextView named textview in a linear layout(This layout will repeat for your each row in ListView).
Dont forget to set image in ImageView to any defult icon or something.
in your class that extends ListActivity simply enter following line and you are done.
setListAdapter(new ArrayAdapter<String>(getApplicationContext(),R.layout.list_item,R.id.textview,COUNTRIES));
In case you stuck anywhere you can ask.
You need to write a custom layout for the rows and pass it to the Adapter that defines the content of the list (you most probably want to write your own, but there may be some predefined ones).
See e.g. this TweetAdapter
that uses this layout
The left screenshot shows how this looks like.
