[android-developers] RelativeLayout problems
I'm working on some test code, just playing around with some image processing methods, and this display may well end up being used in an app for image processing. The layout uses a RelativeLayout, with the relevant portion shown below: --- CUT HERE --- ImageView android:id=@+id/originalView android:scaleType=fitXY android:adjustViewBounds=true android:layout_alignParentLeft=true android:layout_alignParentTop=true android:layout_width=wrap_content android:layout_height=wrap_content / ImageView android:id=@+id/filteredView android:scaleType=fitXY android:adjustViewBounds=true android:layout_alignParentTop=true android:layout_toRightOf=@id/originalView android:layout_width=wrap_content android:layout_height=wrap_content / and after a SeekBar and its two TextViews, which work fine, a ListView, which is also fine: ListView android:id=@+id/filterList android:textSize=22sp android:layout_alignParentTop=true android:layout_alignParentRight=true android:layout_height=fill_parent android:layout_width=300dp /ListView --- CUT HERE --- Note that in the layout, the second (filtered) ImageView is configured to align to the right of the original, and on the top of the display. I want to make this right, from the beginning, in case I do use this layout for image processing (or at least, the final version of it---it's not finished yet). To do that, I plan on scaling the two ImageViews (which, in turn, will scale the images inside, as I'm using fitXY for the scaling method for the ImageViews). I'm trying to scale these to equal fractions of the remaining screen width (orientation set to landscape) after the ListView on the far right. If I hard-code the ImaveView widths for my tablet, it works fine. If I try to resize these from Java, the two ImageViews, which are supposed to be side by side, end up with the filtered (result) ImageView ON TOP of the one for the original image. This is definitely not what I'm trying to do. This is the code to resize the ImageViews: // original is a reduced-size copy of the real original bitmap int oiw = (float) original.getWidth(); int oih = (float) original.getHeight(); // Scale the two ImageViews relative to the display size, maintaining // the correct aspect ratio. The ListView on the right of these is // 300dp wide, and I leave room for padding int iw = (int) ((dw - 340) / 2); int ih = (int) (iw * (float)(oih/oiw)); // and these are the lines I suspect are causing the error // origView.setLayoutParams(new RelativeLayout.LayoutParams(iw, ih)); filtView.setLayoutParams(new RelativeLayout.LayoutParams(iw, ih)); Again, without the above re-sizing from Java (and the ImageView sizes hard-coded in XML), the layout works fine. I'm assuming that the problem is something I'm doing, and not a bug in RelativeLayout itself (obviously...). But whatever the problem is, I can't see it, and have yet to find any reference that gives me any kind of a hint as to what I'm doing wrong. Can anyone here see what's wrong? If so, how would I fix it? Oh, as a side note: when I tried the above code with an intermediate step (calculate the aspect ratio BEFORE using it in the calculation for re-sizing, as follows (with the original image width, oiw, and height, either ints or floats...casting every calculation to float), I get the same result either way: float aspect = (float) oih/oiw; (yes, technically, that's 1/aspect ratio ... it's for the math that follows to get the new height from the new width). No matter what, it ends up being 0.0 (should be 0.75 for the test image in use). Put that inline as above, and it works. Apparently, Android doesn't know that (float) 2/3 is 0.666 (ad infinitum), NOT 0.0 The same happens if the two original dimensions are both floats. Btw, the layout should look something like this: Top of displayt: ImageView ImageView ListView Below that: Filter Level (list continued) Below that: Seekbar - Value (list continued) Below that: Red (list continued) Below that: Seekbar - Value (list continued) Below that: Green(list continued) Below that: Seekbar - Value (list continued) Below that: Blue (list continued) Below that: Seekbar - Value (list continued) Thanks, --jim -- THE SCORE: ME: 2 CANCER: 0 73 DE N5IAL (/4)MiSTie #49997 Running FreeBSD 7.0 spooky1...@gmail.com ICBM/Hurricane: 30.44406N 86.59909W Do not look into waveguide with remaining eye!

Re: [android-developers] RelativeLayout problems
I fixed the id problem that was pointed out by the previous reply. It made no difference.

Click 'resume execution' in Eclipse, and again if necessary. You only get logcat output (and the close dialog on the device) once the exception has propagated to the top-level exception handler. I tried clicking on resume. Twice. The app exited, the debugger disconnected from the Emulator, and still no logcat output. 2 - Logcat window in Eclipse is very nice (filtering, color highlighting), but just too small. Not on my screen. I re-arranged the tabs in Eclipse, and have a 24 1920x1200 monitor. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] RelativeLayout problems
I'm attempting a not-that-complex layout using RelativeLayout, and getting a weird problem. When I set things up in a way that seems correct, I get: Thread [3 main] (Suspended (exception IllegalStateException)) RelativeLayout$DependencyGraph.getSortedViews(View[], int...) line: 1260 RelativeLayout.sortChildren() line: 281 RelativeLayout.onMeasure(int, int) line: 299 RelativeLayout(View).measure(int, int) line: 7964 The full layout is at the bottom of this msg. If I delete just one line, android:layout_toRightOf=@id/Spin from the 3rd widget (ImageButton), the layout then sort-of works. (well, at least it doesn't crash) The 1st NumberPicker (SpinMeasure) is at the top of the screen - but is the full screen width. The BtnRun is at the top right corner, overlapping SpinMeasure. BtnMute and CenterLayout appear correct. SpinRate isn't visible. It's either not there, or is under SpinMeasure.

Re: [android-developers] RelativeLayout problems
I think you trying to use id which is not created : android:id=@id/SpinRate try this android:id=@+id/SpinRate On Mon, Dec 27, 2010 at 9:14 AM, John Lussmyer johnlussm...@gmail.comwrote: I'm attempting a not-that-complex layout using RelativeLayout, and getting a weird problem.

Re: [android-developers] RelativeLayout problems
John, Two suggestions: 1 - When your app suspends like this, it means it's crashing, but hasn't quite crashed all the way yet, which is why there is no logcat output at that point. Click 'resume execution' in Eclipse, and again if necessary. You only get logcat output (and the close dialog on the device) once the exception has propagated to the top-level exception handler. 2 - Logcat window in Eclipse is very nice (filtering, color highlighting), but just too small. Run adb logcat in a command line window, make the window large, and set a nice ample scrollback value in properties - with this, you'll much more. -- Kostya 27.12.2010 6:44, John Lussmyer пишет: I'm attempting a not-that-complex layout using RelativeLayout, and getting a weird problem.
