custom-adapter

I'm trying to make a Gallery widget using HorizontalScrollView , So inside the HorizontalScrollView I add ImageView s, and the problem is that I'm going to add 600+ images! Can I make some kind of a custom adapter in order to override the GetView method and utilize convertView in order to make the app smoother and avoid adding 600+ views at the same time? HorizontalScrollView can contain only one View , so you have to draw that whole View anytime you are drawing any part of it. This could, however, be worked around by extending ViewGroup as child of your HorizontalScrollView using your custom

I followed a good tutorial, with some changes, to create a custom ListView that will allow me to display multiple images for each row in my ListView. What I would like to do is highlight by selecting multiple items in the list and then perform some sort of action to all of those list items by selecting an option on my Options Menu. However, the problem I seem to be running into is that I cannot select multiple items, even though I have added android:choiceMode="multipleChoice" to the ListView in the .xml file. I realize that this can be done using check boxes or radio buttons, but I would

I am using a Custom Adapter with AutoCompleteTextView. It works fine on the emulator and my tablet. However, there is an issue on my phone in landscape mode. The auto complete hints being shown in this mode are object info rather than text. However, when I select any item the fields gets populated correctly with text in the respective fields. Auto Complete for other fields that are based on Android Stock Array Adapter works fine. Do I have to do something for this in my Custom Adapter? I saw only one similar question on SO. One response for that question was talking about overriding the

I have an Android application with a ListView in it, the ListView will setup fine but now I want a image in the ListView to be clickable. I do this by using 2 classes, the Activity class (parent) and an ArrayAdapter to fill the list.

First the Activity class: public class parent_class extends Activity
