Example: You drag the list up and down, and now you want to konw which element is on the center of the screen?

View 1 Replies View RelatedI am on Android 2.1 and I have one multi column Custom listview Using BaseAdapter with an editable edittext at the end of the listview. If the data in the listview do not contain the data of user choice then user should be able to enter data. If the data is already there in the list user will be able to select the data using custom selector. If a selection is made in the list view and user wanted to enter data in the text field at the bottom after selection then the marker in the list view should be unselected. I tried to use onclick() method on edit text using click listener. First time when it is clicked, edit text is getting focus and onclick() method is not fired. And when it is clicked second time, onclick() method is fired and notifyDataSetChanged() method is called. I tried to call the notifyDataSetChanged() method from the Focus Listener, list view selection is gone in my first attempt and edit text is not receiving any data input from the keyboard (frozen).

View 1 Replies View RelatedI have a list using a customized BaseAdapter. When one element of the list is hit during a long time, a contextual menu appears. I want to use this one to delete or edit the selected item but I don't know how to get id or anything else that could help me.
I tried getListView.getSelectedItem() thinking that it will give me the object returned by the method getItem(int position) inherited in my customized BaseAdapter. I got null. When I tried getSelectedItemId(), I got -1.
Does someone have a solution?
I'm sure there's a simple answer to this, but...Why can't I nest another view type within a View element? In my layout file I try:

And this gives me a ClassCastException. Why?
Is it possible to set the absolute position of a view in android? (I know that there is an AbsoluteLayout, but it's deprecated...)

View 1 Replies View RelatedI have a HorizontalScrollView with a series of CompoundButtons. I want to find the (x,y) for a given child view. I have tried using:
getLocationOnScreen()
getLocalVisibleRect()
getChildVisibleRect()
like this:
View tmpView = this.findViewById(viewId);
Rect hitRect = new Rect();
tmpView.getLocalVisibleRect(hitRect);
the hitRect is always 0,0 - 0,0.
I need the x,y mainly to scroll to a particular child view. Any help is greatly appreciated.

I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?

View 13 Replies View RelatedI am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............
I'm trying to get the scroll position on a ListActivity. Here is what I'm trying to do: I have a list activity that is populated from an XML file. Another thread downloads all pictures so the user can see the list while the thread is still downloading the files.
What I'm trying to do is when the thread finishes getting all pics it reads the listview scroll position, refresh the listview and scroll to that position again.
ListView main = getListView(); <-- not sure if I'm really getting the ListView this way. int scY = main.getScrollY(); Log.d("Scroll", scY + " "); <--- this is printing zero even when at the moment I run this I already scrolled the list. setListAdapter(listadapter); main.scrollTo(0, scY);
How do I find the position of the item clicked in an Expandable List.
In a list view the listView.getPositionForView(v); is present which gives the position of the clicked item.
But in an expandable list how do i get to know the position of the grouppostion or the childposition
Can anyone give me a tip for how to get the position of a view what is a child of an AbsoluteLayout? I want to do this for drag and drop the selected view.

View 2 Replies View RelatedI'm trying to do something which seems simple. I want to have a map view, with a menu that slides up from the bottom of the screen where settings (for overlay) can be adjusted. However when I use a TranslateAnimation to affect the y position of the LinearLayout (which holds the menu), the buttons in the LinearLayout move, but there "hit area" stays in the same position as they were before the animation.
CODE:.........
I've also looked into tweening the view's marginTop value, but haven't even been able to determine how that would be done.
I'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

View 1 Replies View RelatedIf you use an AbsoluteLayout (I know that it is deprecated, but it was the only way to solve my problem ) you can give the childViews the tag "android:layout_x" and "android:layout_y" to set their absolute position within the AbsoluteLayout.
However I dont want to set these informationen in the xml, because I only know them at runtime. So how can I set these parameters at runtime programmatically? I dont see any method on the View like view.setLayoutX(int x) or something.
Here is my XML, which works fine, when I set the layout_x and layout_y values. code...
