I am more familiar with web, but I am programming an Android app.
This is a beginner question, but I'm having trouble wrapping my head around reusable views in Android. On the web, I would create a partial view and pass parameters to be added via a templating language. What is the best way to do this on Android?
More specifically, I am trying to add a grid view where each slot of the grid has an image and a subtitle with a border. I want to dynamically load the image and subtitle from the database, and add an unknown number of images to the grid.
How could I create a view to hold the images and subtitles and then dynamically load them into the grid with different data?
Creating a GridView programatically:

This should help you with the skeleton and you can add an ImageView and TextView as per your requirements.

You need a GridView and an Adapter to load the items dynamically into your grid. I can't post the code actually here, because it would be a very long answer. But Here is a nice tutorial to get you started. In the example, there is a grid build with dynamic images showing step by step what you're looking for.

Actually i had already posted this question but it was on hold .Well i am creating an android app which comprises of a grid view form in the Homescreen page. However i want my grid view in form of buttons that will lead to different activities.Can anyone suggest me how to do it? here is a sample of what i am trying to do:
Homescreen
You can use a GridView (link) and add your Items to it's Adapter. EDIT: The elements in this grid are then clickable and you just have to react to the clicks. Here you can find an example of how GridView is used.
I'm using a RecyclerView to display a list of data from server. The data contain text and an uncertain number of urls of images with HTML tag. For each item, I'm now using HTML.fromHTML() with a ImageGetter to parse the data, get images and display them in a TextView. However, the images in TextView cannot interact with user. Events on the images like click, magnifying and save are not supported by TextView. And I tried using a Webview instead, but its performance is poor.
I also tried to write a compound view which extends a LinearLayout, and add TextViews and ImageViews dynamically (the number of images for each item are not certain), but it behaved strangely in the RecyclerView.
Is there any better idea or should I improve my solutions forementioned?
Thanks in advance!
The solution has been found by myself with the help of other programmers on StackOverFlow. For those who may see this question, please check Android - Custom dynamically-generated compound View recreated in RecyclerView, causing poor performance.
The idea is simple, creating a CompoundView extending LinearLayout which adds TextViews and ImageViews dynamically based on the data attached. Note that the processes of creating views and setting data for the them are seperate. For other details, please check the url above.
I have some data in my data base and i want to display it in android phone.I want to display my data on Grid-view because there is continuous variation in my data therefore i want to display in android like asp.net gridivew.Please anyone help me to do this or any example code to do this
You need to have two things for the Gridview:
Use Gridview component in a layout.
Inflate the elements in a getView method and set elements position by position to the Gridview items.
You can follow this link to understand it:
http://android-coding.blogspot.in/2011/09/simple-gridview-example.html
You are on the right track as you have decided yo use a dynamic view for your varying data. You can use any one of the dynamic view(list view, grid view, gallery, etc) depending on the kind of data you need to display.
If you are not familiar with these dynamic views then you should first go through some tutorials on implementation of these views. First try with a basic program for understanding the concepts. Once you are clear with the concepts then all you need to do is to replace the underneath data with the data fetched from the data base.
There are lots of tutorial available on net. Here are some links:
GridView tutorial
ListView tutorial

hi i am going to make a to-do list so what i need is that to assign my task and view it as a list view in those list view need 3 text view and 3 images in this 3 images represent 3 activity like alarm, calendar and so on when i click these images its open seperatly i had i know to retrieve the data's from database to list view but did not know how to set multiple image in a single list.and make those images click able.now how can i do that i tried the lazy adaptor but it is used in the parsing phases there is no parsing in my application please help me
there are many different post all over the place about creating custom ListView items. this one is very helpfull and similar to what you want to do.
when working with images and ListViews, it's very important to implement Lazy image loading. the best implementation I know, is ferdovlasove's LazyAdapter.
enjoy...
hi i want to split my gallery with 5 images in 2 rows.
Please let me know how to do this in android using Gallery View & custom adapter for Gallery view.
Is there any sample code available please share it, i have already checked the previous posts in this site.
Thanks
If you still need this and Pagination instead of scroll will work for you, you might look at: https://github.com/sfarooq/PaginatedGallery
I designed it using ViewPager so you can manipulate the adapter to send any kind of views you want including two row views.
If you must use scrolling galleries you could implement two separate gallery in a vertical orientation and send touch events from each to the other.
