Android : Get Absolute Coordinates Of A View?

Feb 8, 2010

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).

Android :: Mismatch Of Event Coordinates And View Coordinates

Jun 30, 2010

I've been trying to write a little application that recognizes custom events in Android: you hold your finger over a TextView for a certain length of time, and it changes color.I'm using the MotionEvent coordinates and checking if they are within the bounds of a particular TextView, which is within a table.I am just attaching the onTouch listener to the table within the activity.But I get weird errors: the coordinates seem to be off by one view (i.e. if I touch the view below the view above reacts); or sometimes one will react, and the other will not. Any idea what might be going on?

Android : Change Absolute Position Of A View Programmatically?

Aug 9, 2010

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...

Android : Add View Progamatically To Activity's Absolute Layoute Setting It's Possition?

Oct 7, 2010

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();

Android :: How To Get Absolute Time?

Aug 20, 2010

I'll notify something to user after 30 minutes for example. so I need to get a time which is not changable by user or anything. Does it call UTC? I guess I need to get current time and it should have nothing to do with user handle or location actually, I'm focusing '30minutes from now' rather than current time. It also should work even in case of power off and on. Can I use alarm manager for this?

Android : Place Controls At Absolute Positions - Custom ViewGroup

Sep 26, 2010

I have a custom ViewGroup. The idea is to be able to place controls at absolute positions and then have the ViewGroup scale those controls based on the difference in the screen dimensions with respect to the original design dimensions. I am using the code below. In response to the 'onMeasure' message, I am storing the width and height of the view. Then on the 'onLayout' message I am computing new dimensions for the child controls and adjusting their sizes proportionally. This all works to some degree. However for certain controls (e.g. button controls), the control resizes, but the text inside does not remain centered within the control. I am thinking that there is some other call I need to make to update the child controls after I change their size.

HTC EVO 4G :: Syncing Music Absolute Nightmare

Jun 13, 2010

I got my Evo 4g and I'm absolutely in love with it, but getting music to show up in ANY music player without a flaw is an absolute nightmare. If I use Tunesync the music all gets onto the card, but the playlists don't appear. If I use Doubletwist, not only does the sync take millennia, the playlists do not show up and I get duplicate playlists. If I use Salling Media, I have the same problem I have with playlist, and I get an error about source files not being htere. After over 6 hours of googling and more than 5 sd card reformats, I'm abotu to give up. Have any users succeeded in getting all the playlists to show up with no duplicates and all of the songs they wanted? If so, how?

HTC Incredible :: Verizon Screen Protectors Are Absolute Disappointment

May 1, 2010

First post and already I am complaining. I guess most of you know already that they don't fit the entire front plate, only the center screen. But I was willing to live with that till better ones came out, but what really got me (unless I did something wrong) was the second tab you are supposed to pull off after installing the shield is stuck on like a sticker that has glue on the back side and left part of the sticker stuck on the screen.On my second attempt I used Goo Gone to get the sticker off first but the application for applying still came out messy.Anyway just a heads up stay away.On a side note one thing that doesnt suck was the red and black gradient case I got for the phone. It feels nice and I believe will absorb most falls to the ground while still protecting the phone. It also looks great and seems to sit flush to the ground so that the camera is not touching the surface directly.

Android : Absolute Centering In Android Layout

Jul 22, 2010

I've spent so much time trying to figure this out. I'm building a dialog layout and trying to get the Title centered relative to the dialog while having 2 buttons on either side of the title. The buttons are to be 'gravity-ed' towards far left and far right.

The easy part is centering the dialog, OR doing the buttons far left and far right. It's getting them to play nice with each other on the same line.

Easy way to think about it:

Title is centered in dialog
2 Buttons are independently aligned left and right on the same line. Any thoughts on how to do this?
