View 4 Replies View RelatedThe documentation at http://code.google.com/android/reference/android/widget/AbsoluteLayout.html says:
onLayout(boolean changed, int l, int t, int r, int b) //Called from layout when this view should assign a size and position to each of its children. So I overrode it like this:
@Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
Log.d("test", "In MainLayout.onLayout");
int childCount = getChildCount();
for (int childIndex = 0; childIndex < childCount; childIndex++) {
getChildAt(childIndex).setLayoutParams(new LayoutParams(100, 100, 100, 100));
}
super.onLayout(changed, l, t, r, b);
}
I am declaring the child elements (buttons) in the XML for the layout. This correctly sets the position of the buttons but not the size. The size is being taken from what is defined in the XML (it's a required attribute).
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.
Can I get a View's x/y position (relative to the root layout of my Activity) in Android?
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 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));

Now we got to the question if it's possible to get the actual position of an ListElement.

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?
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 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 2 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
View 4 Replies View RelatedI'm trying to set the selection of a Gallery in code. I would like to have the Gallery smoothly roll down a few items over the duration of a second or two. At frist glance, it appears that two members would to the trick:Gallery.setAnimationDuration(int animationDurationMillis); Gallery.setSelection(int position, boolean animate); It turns out that the setAnimationDuration only seems to affect the rubber-bandy "return-to-center" effect of the Gallery. In other words, when a gallery comes to rest after a fling, and a gallery item is off center, the animationDurationMillis is used to control the duration of the Gallery centering up the item. However, the value seems to have no effect on the setSelection. No matter what value is set with setAnimationDuration, the Gallery seems to render about 2 or 3 frames when flying between items 1 and 10 for example. Is this working as designed? Does anyone know a trick or workaround that would let me properly animate setSelection? I'd be especially grateful if we could do it with an "Ease Out" effect.
View 3 Replies View RelatedOn my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.
I understand the problems with assigning a fixed position to UI components, but I would like to use AbsoluteLayout in a way such that the position of the components are chosen dynamically, calculated based on the screen size.Here is why I am thinking this may be easiest:I want to display a nXm grid of imageViews on the screen (n,m chosen by the user) with 0 padding betweeen the image Views.With absoluteLayout, I could easily choose the size of the imageViews and in a way that maximizes the amount of the screen that is used.The reason that using relativeLayout or LineraLayouts may not work for this is because when a user touches an image in this grid, I would like it to "pulse" (quickly scale larger than back to its normal size).If I scale an imageView using realtive or linear layout,it would resize the adjacent imageViews (since the padding is 0), which I don't want.
I would prefer permitting temporary overlapping of the imageViews.This is currently the approach I have taken, except instead of changing the position of imageViews, I am just drawing bitmaps to the canvas at the locations I calculated.I can't use the animation framework, however, on bitmaps that I draw to a canvas.Is this an acceptable use for AbsoluteLayout, or is there a better way to achieve what I want to do here?
I have just realised that AbsoluteLayout has been deprecated in the latest sdk, however I have designed my apps based on AbsoluteLayout and it is very difficult for me to remove them and change it to a different layout. Can someone help me as to how I should proceed? Absolute layout was really helpful in positioning the elements to be accurate. One could always had different layout definitions for different screen sizes, and based on the current width and height the required layout can be set. Removing of AbsoluteLayout is creating a lot of frustration to me as I have already designed most of the things using it. Somebody please help me out.

View 2 Replies View RelatedI see posts saying that FrameLayout is the alternative, and that I should use margins to position things (this strikes me as wildly counter intuitive, but ok... if it works, I'll take it). However, I can't get it to work, so, I'm looking for assistance. I'm aware of the fact that this may mean different things on different devices. I'm ok with that. I simply need a way to, programatically, and at run time, place an item at a SPECIFIC location. I don't want to rely on gravity (or the laws of thermodynamics). I just want to specify a location and have the element appear there :)

View 1 Replies View RelatedThere are the following layout options to create interfaces for android.
AbsoluteLayout
FrameLayout
LinearLayout
TableLayout
RelativeLayout (and some more)
Which of the following is most suitable for designing simple games? Guessing that the absoluteLayout is easiest, but will it be problems with different screen sizes? What do you recommend?
