Hello I have a listview set up with an icon to the left of each row using a row.xml. When the activity is started i would like to have one icon but when a the menu is opened and an item there is selected i want to change the icon in just one position. For example
I Cat
I Dog
I Mouse
I Food
Where I is my icon and the rest then the rest is my list i would like to change just the I in the second position so that the list would look like this
I Cat
D Dog
I Mouse
I Food
So some how get all the positions and then do like
for (position 1){
change the imageview
}
But i still want the first listview to be the default how can i change the icon of just one row? Thank you for any help
What's your underlying data structure that you're binding to? If it's a Cursor you could call notifyChange on a Content resolver to let the adapter know the data has been updated.
Ended up doing this
ImageView imageView = (ImageView) lView.getChildAt(position).findViewById(R.id.checkbox);
imageView.setImageResource(R.drawable.checkbox);

I need to make a spinner like on picture below. My question is - how to add arrow(dropdown hint) to right part for first element in spinner. Better if it(I mean arrow but not "Select test") will disappear after user press it
Add in spinner arraylist zero position as "Select Type" and you want to add arrow So,you need to take image view in right side of your spinner,and when you get spinner item selected position is 0 at that time you need to visible imageview and other position hide imagview.
I hope this can help you!
Thank You.
As shown in the image when I click on an item in the list view. Buttons show up.
I want to hide buttons when I click on different items and show on current clicked item.
How can I make it work?
Need to preserve view into a variable like prevView. and then click on another item.
Check whether prevView is null or not. If not null. then get button id .
e.g. prevView.findViewById();
and Make their visibility.GONE. and also null prevView.
I hope this will help you.
You can achieve this by making a model class.
take variable for particular buttons in Model. after clicking on a different item set true/false tag in the model and show/hide view according to that tag.
You should be using an expandable ListView so that you can get the buttons shown when you tap on the list item and it get closed when you tap on the other item in the list.
The question might be duplicate ..sorry for that.
I have an activity (test activity) and array adapter (test array) for same.
The list contains image and text. but the image is not displayed always. It has some condition. So look is like
---------------------------------------
image1 text1
test2
test3
image4 test4
---------------------------------------
So test activity display the above list on screen.
Now i want to do different screen load on image (image activity) and text (text activity).
As the on-click handler will be in separate file (test array) i am not sure how to return to test activity and to specific task.
actually i have a list view with image and text.
Below are some scenario
Image will not be present on each row.
If image is present then Onclick of image shown other screen (for example image activity).
if user click other than image that is text show text activity screen).
What i have done is i have a list click handler in a separate file that is ArrayAdapter so i cant't do image click listener there.
So the issue was how to identify which row image is clicked?
Solution:
After lots of R&D and code changes i done below and its working:
I have added android:onClick="ImageClickHandler" for image click in xml.
and during row creation i have set row position as Id.
So when clicked on image you can get position by view.getId(), so u have the position when u click on image and hence you can get complete data on that row.
Might be there is another way....but this is what work for me.
My ListView has to be customized like, it should have three imageView in each ListItem along with the name and date that has to populated from the DB,added with that, once i click upon the a list item ,that corresponding Listitem information has to be displayed in another Screen...The Size of the List should be based on the Cursor object from DB..and it should be possible to add data in to the Listview..too
Can anybody give me any suggestion/snippet/resource of how to proceed the above said..
Please check the ScreenShot of ListView that i mentioned..(My ListView should have to be like this only)..
Thanks in advance.....
you can use inside every list item a WebView loadin your html template that contains the name, date and the 3 images, and use a JavaScript interface to interact with your code
you must load in every listitem something similar to this Example but with 3 images.
hope it helps you
I choose an item to remove from my ListView. And after the Item was removed, my ListView was scrolled back and display at the first Item.
I want my ListView display in right place where the Item I had removed (It like remove a contact in Android Contact list). How can I do that?
I suppose you want to update your ListView display, after you remove an item, right?
When you remove the item, you have to modify your data adapter, and let the ListView change accordingly (something like the MVC pattern behavior). I've seen somewhat similar questions (and the corresponding answers :) ) here and here.
Edit:
Aha, in that case, try using setSelection(int), after recalculating new indices and new item count.
