Is it possible to set the absolute position of a view in android? (I know that there is an AbsoluteLayout, but it's deprecated...)
Lets say I have a screen 240x320px, and I want to put an ImageView which is 20x20px with its center at the position (100,100).
What do I have to do?

I have an image setup inside an absolute panel.I am trying to set it's position via code.But I do not see any applicable method/property to set its position.
Here is my layout.
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/marker" android:src="@drawable/marker" android:layout_y="106dp" android:layout_x="290dp"></ImageView>
</AbsoluteLayout>
Here is my code to set its position...
If 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...
View.getLeft() and View.getTop() give the position of the view relative to the parent.
Is there a way to get the absolute screen position of that view?
Either a way to translate those coordinates into screen coordinates to make a call to get the position in screen coordinates.
I am aware of setSelection(), setSelectionFromTop(), and setSelectionAfterHeaderView(), but none of them seems to do what I want.
Given an item in the list, I want to scroll so that it is in view. If the item is above the visible window of the list, I want to scroll until the item is the first visible item in the list; if the item is below the visible window, I want it to scroll up until it is the last visible item in the list. If the item is already visible, I don't want any scrolling to occur. How do I go about this?
I'm trying to get the absolute screen pixel coordinates of the top left corner of a view. However, all methods I can find such as getLeft() and getRight() don't work as they all seem to be relative to the parent of the view, thus giving me 0. What is the proper way to do this?
If it helps, this is for a 'put the picture back in order' game. I want the user to be able to draw a box to select multiple pieces. My assumption is that the easiest way to do that is to getRawX() and getRawY() from the MotionEvent and then compare those values against the top left corner of the layout holding the pieces. Knowing the size of the pieces, I can then determine how many pieces have been selected. I realise I can use getX() and getY() on the MotionEvent, but as that returns a relative position that makes determining which pieces were selected more difficult. (Not impossible, I know, but it seems unnecessarily complicated).
I have a form with several Views on it, the last one is a Spinner that is bound to an adapter to get it's data from a Web Server via a POST request, at the end I append an additional entry for "Other...". If this option is selected on the spinner, a new EditText View at the bottom where the user enters a custom value, I've managed to get the EditText View to show on the screen, but it's positioned at the very top, over my other Views and I can't seem to find the way to make it appear at the bottom, below the Spinner as I want it to, here is the code I have so far:
EditText suggestCarrierField = new EditText(getBaseContext());
suggestCarrierField.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
suggestCarrierField.setHint("Suggest your carrier");
((AbsoluteLayout) findViewById(R.id.createAccountView)).addView(suggestCarrierField);
((AbsoluteLayout) findViewById(R.id.createAccountView)).invalidate();
My friend and i develop a Android program.
Now we got to the question if it's possible to get the actual position of an ListElement.
Example: You drag the list up and down, and now you want to konw which element is on the center of the screen?
I 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 update view, where I need to preselect the value stored in database for a Spinner.
I was having in mind something like this, but the Adapter has no indexOf method, so I am stuck .
void setSpinner(String value)
{
int pos=getSpinnerField().getAdapter().indexOf(value);
getSpinnerField().setSelection(pos);}
Does smomeone know how I set the scrollbar position in an EditView programmatically.
I'm appending the text during special events but I want the EditView to scroll down to the latest text added so it'll be visible. But default the scrollbar does not move automatically when appending text.
I have an image, say 16px from our designer. I want to Set it as the background image on a view, but the view is larger than the image. So I want to anchor the image at the top of the view, and then have the view fill in the bottom with a solid color.
Is this possible in the current version of android, 1.5_r3?
Here is what I have so far, but the image is scaling to take up the entire view, and I am not sure how to set the image as background and specify a solid color at the same time. I suspect I need to wrap the view in a containing view which has the color specified, is that the best way to do it? code...

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.

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 currently have a view in my Android app and the view is playing a frame animation. I want to animate the view to increase its size to 150%. When I apply a scale animation to it, and the scale animation is completed, I want the view to stay at that new size for the rest of the activities life cycle. Unfortunately right now when the scale up animation is complete, the view snaps back to the original size. How can I get it to keep the new animated tranformation? I'm using myView.startAnimation(AnimationUtils.loadAnimation(mContext,R.anim.scaleUp150));

View 1 Replies View RelatedSample code there is a method getitem(position) in the class of image adapter which returns null for the sample example. However, this method is important and is supposed to return the corresponding data item of the image adapter. For example the image adapter could generate a series of customized image views by magically calling the getview method. How could we implement the getitem(position) method under this case to help us gain access to these customized image views?

View 6 Replies View RelatedI have a custom view that I had to write for a large scrollable image, as the images are larger than the size of the screen. Before, I had tried to do it by putting the image into a ScrollView but that of course didn't work. The view itself is within a RelativeLayout within the activity and at the bottom of the screen I have two buttons that are used for navigation and at the top a TextView with a caption for the activity (the main header is already being used here for instruction). In my below code, I've checked the Hierachy Viewer to confirm all the elements are loaded and in the Activity I can see the TextView, however it overlays the ZN5ScrollView area and below the image I just have a blank area of the size defined rather than my buttons. For the bottom navigation, the Hierachy Viewer is saying the absolute_y of the bottom navigation is 480. I'm wondering if anyone can help with my layout code here to get this working correctly? Bottom navigation is 50px high, ZN5ScrollView is 365px above the navigation, and the TextView takes up the rest of the area at the top

I have 2 queries:
1). I want to display kind of screen lik
Heading ImageButton1 ImageButton2

Same way number of records
So i have used absolute layout programmatically instead of using xml, is it advisable or there is some other way?
2). At that time of displaying this view, i have to set unique Id to each record and get Id whenever any of 2 buttons pressed of any record. Can anyone tel me how is that possible?
Means in short how to set and get id which button of which record is selected?
I have checked setId() method of the view, it accepts integer parameter. But there are possibilities of assigning same id to different views, which may create problem for me while i do findViewbyId().
My question is "How to set unique id to the view programatically?"

How do I set up an xml layout where an OpenGL view is part of it? As I do now is set the OpenGL view as the only view with setContentView(). But I would like to create an xml layout that includes the OpenGL view. Lets say I want to have the OpenGL view mainly and a small TextView at the bottom.
Is this even possible? Or can an OpenGL view only be the one and only view?
