I want to add some views in each row of list view. When I add text view and image view in getView() of ArrayAdapter,it works. But after I add other kind of views (like Check Box and Image Button...), I can't select the list row touching down screen directly, I only can select by key down, up and ok.

I am developing an application which requires me to load first twenty rows (consisting on icons and two text fields) and if I have more rows I need to display a button. When i click this button I want to display more twenty rows( again iconified).My current approach which is working is that on the button click I create one more activity which will have the previous rows and the new rows. In this case the cursor is set to the very first row.But I want to have something like Facebooks "Older Post" where the new rows get appended to the old ones and the cursor is set to the last row to which the new rows are added.Please can anyone give me ideas on how to achieve this. That is, how to add rows (iconified) to the existing array adapter.
View 2 Replies View RelatedI'm very new to Android programming, so this is probably something pretty basic. I just have an xml layout with a few buttons. I'm trying to follow the model given by the JetBoy demo, so I'm adding a view to the layout which extends SurfaceView. When this new view is put in my xml layout, I just get a blank screen.
Here's the XML layout if it helps. The gameview element is what causes the screen to be blank

View 2 Replies View RelatedOften, a simple of ArrayAdapter does what I want and during early development I will provide the android.R.simple_list_item_1 for the view id required by the ArrayAdapter constructor. Is it possible to provide a customized view which is based on the android.R.simple_list_item_1 to the ArrayAdapter constructor?
I do not fully understand Android's 'include' functionality, but what I would like to do is something like:
Define a new TextView based on customizing the android.R.simple_list_item_1.
(I have no idea what the valid syntax would be)
code...
Reference my customized TextView. I assume that something like this would go into my layout directory. Then in my code I would do something like:
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.id.MyTextView, null);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, view.getId(), myArrayOfData);
Is this possible and if it is, what is the appropriate syntax to accomplish what I want?
So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my imageview to be at the bottom. However, a child of a ScrollView dont seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?
I need to draw a child view containing a rectangle and button on top of the content view at particular location on the parent (content view). How can I do this? Did not find an explicit way to set origin of child view?
View 1 Replies View RelatedJust a quick question about the Captivate. I just got myself an HTC Aria and I love how easy it is to use the touch screen on it. Its extremely responsive. Now my sister has the SamSung Instinct on Sprint and the touch screen is horrible compared to HTCs touch on the Aria. Im thinking about taking the HTC back to AT&T and getting the Samsung Captivate. I am just worried about the touch screen on it and if it will be like the Instincts? If the touch is as good as HTCs Ill get it. If its not, then Ill stick with the Aria because despite its size, its an extremely fun and responsive phone. Any thoughts?

View 2 Replies View RelatedI was attempting to add a custom view in XML, but I kept getting force closes. It works fine when I just find the parent and use addView() so it isn't the code. I'm pretty sure I'm just getting the constructors wrong. Does anyone have any experience with this?

Is there a possibility to add a view or derivative (button, textview, imageview etc...) to another view without having to go through layouts?
I have a class called ScreenView, it derives from View (e.g. public class ScreenView extends View).
I wanted to display text into it, labels, images etc..
On an iPhone it's trivial, simply create my objects and use addSubview method ; you can embed any UI objects into another. Most UI toolkits work that way too.
Problem with layouts is that I haven't found an easy way to properly position a subview (say a text view) in a given location of the enclosing View. I want one to contain the other...
I was hoping I had missed something in the documentation (which is far from being intuitive that's for sure) and I could do something like myView.addView(subview). But it ain't so :)
As a side question, what is the closest to iPhone's UILabel in the Android world?
A UILabel can contain a text or a graphic. Right now I've been using TextView and ImageView but they aren't anywhere as flexible when it comes to layout as a UILabel
Edit: Making my View inherit from ViewGoup instead, let me add subview..
However, I want to draw in my view. I found that when ScreenView extends ViewGroup, the onDraw function is never called then.
Something like:
CODE:..........
Would paint in yellow my view if ScreenView extends View ; but not if it extends ViewGroup.
How do you draw directly in the view then?
I am working on adding vertical and horizontal scrollbars in a custom drawn View. I have overridden the compute*ScrollOffset, compute*ScrollRange, etc methods and have enabled the scrollbars by called set*ScrollBarEnabled. However, I do not see the scrollbars in my View, even after a call to scrollBy, which according to the documentation calls awakenScrollbars (I assumed awakenScrollbars is not required as the scrollbars do not auto-fade - isScrollbarFadingEnabled returns false).

At the beggining I was trying to use a ListView but as far I as know there is a bug using listview inside a scrollview. I was doing this because i have more components on the view that should be scrolled together with the list view. So I decided to remove the listview and implement a simple linear layout where i will be adding each element bellow other and so on.
The layout for the activity is as folow (layout/workaround.xml) and i would like to start adding the elements below the top bar.

I have a custom view (an extension of a TextView) that I want to dynamically add to my Layout (don't want to include it in the main.xml file).
The book says to fetch the RelativeLayout using findViewById() in my java code then create a new instance of my custom view, then use addView on the RelativeLayout to add the new view.
I'm not getting any errors, but when I click my button to add the new view, nothing is happening (view isn't being added). Do I need to set additional properties on my custom view (layout width, layout height for example) in order for it to be shown?

I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
This all works great.
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
CODE:..........
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
CODE:................
So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.

View 3 Replies View RelatedI need to make a service that capture all touch events, not in a specific view or when an specific activity is open. This service is started when the boot is completed (and I have an app to stop/play this service when I want it). So it write something (in a Toast) when the user touch any place in the screen.
Can I do this? Or only in specifics things (with OnTouchListener and adding specifics views, for example)?

View 1 Replies View RelatedI have a custom Android view which overrides onTouchEvent(MotionEvent) to handle horizontal scrolling of content within the view. However, when the ScrollView in which this is contained scrolls vertically, the custom view stops receiving touch events. Ideally what I want is for the custom view to continue receiving events so it can handle its own horizontal scrolling, while the containing view hierarchy deals with vertical scrolling.
Is there any way to continue receiving those motion events on scroll? If not, is there any other way to get the touch events I need?
