3,236,994 | 3,236,995 | GridView - sometimes rows are top-aligned, sometimes they're bottom-aligned! | <p>I am using a GridView. Four items in a column. Each element is composed of the following layout:</p>
<pre><code><LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="32dip"
android:layout_height="32dip"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="11dip"
android:paddingTop="2dip" />
</LinearLayout>
</code></pre>
<p>So each element is a small image with a bit of text below it. The layout works great on the first pass. However, if an item's text is long, it wraps to two lines. This works ok, until you scroll it in and out of view. By default, all the images in a row are top-aligned. When you scroll a row off-screen, then back on screen, you'll see that the row somehow gets bottom-aligned. It looks like:</p>
<p>First layout:</p>
<pre><code>[image] [image] [image]
[text] [text] [text
wrap]
</code></pre>
<p>so even though the third element has 2 lines of text, the tops are aligned which is perfect. If I scroll this row off screen, then back on, it looks like this:</p>
<pre><code> [image]
[image] [image] [text
[text] [text] wrap]
</code></pre>
<p>so the row gets bottom-aligned here. I'm not sure if this is a bug in GridView, or if there's some way to control the layout to always top-align rows. I've tried setting the gravity of the element layout to "top", no good. There also doesn't appear to be any setting unique to GridView to control this. Any ideas?</p>
<p>Thanks</p>

2,999,608 | 2,999,609 | Can i change the value of local variable sitting inside the function in PHP? | <p>I was reading an article about Data Encapsulation in PHP, and the author explained in such a way that it made me to wonder if this is really possible? here is what he said. </p>
<blockquote>
<p>The primary purpose of encapsulation
(scope) is to ensure that you write
code that can't be broken. This
applies to scope in general, so let me
use a simpler example of a local
variable inside a function:</p>
</blockquote>
<pre><code>function xyz ($x) {
$y = 1;
while ($y <= 10) {
$array[] = $y * $x;
$y++;
}
return $array;
}
</code></pre>
<blockquote>
<p>The purpose of this function is to
pass a number and return an array. The
example code is pretty basic. In order
for function xyz() to be dependable,
you need to be guaranteed that it does
the exact same thing every time. So
what if someone had the ability to
from the outside change that initial
value of $y or $array? Or even $x? If
you were able to do that from outside
of the function, you could no longer
guarantee what that function is
returning.</p>
</blockquote>
<p>Now this made me wonder can i really change the value of local variable sitting inside the function without using any argument as demonstrated above ?? if it is possible how do i do it?</p>
<p>thank you..</p>

1,498,799 | 1,498,800 | Preview aspect ratio is different on different devices | <p>in my app I have a preview screen. On one device (LG, with Android 2.2, 320x480 screen) and another one (HTC, with Android 2.3, 480x800 screen) everything is OK. In both cases the list of supported preview sizes include one that fits the screen size exactly, I choose it and the image is perfect.
The problem comes with yet another device, having a screen similar to the first one (Samsung, Android 2.3, 320x480 screen). Regardless of the fact that I select a preview size that fits the screen size, as in previous cases, the image doe not preserve its aspect ratio; circles appear oval; the image is squeezed along the short axis of the screen. It seems the hardware itself, in order to obtain a 320x480 preview, squeezes the image (the camera has a form factor 4:3, while the screen has a form factor 3:2).
So I have altered the layout params of the view where the preview appears, in order to fit the form factor of the camera (size: 360x480. This PARTIALLY solves the problem; actually, to solve it completely I had to set 380x480 (!!!).
The fact is that I can't possibly find any API that tells me about this different behavior, so that I can automatically compensate for it. Not even the <a href="http://developer.android.com/reference/android/hardware/Camera.Parameters.html#getHorizontalViewAngle%28%29" rel="nofollow">Camera.Parameters.getHorizontalViewAngle</a> and <a href="http://developer.android.com/reference/android/hardware/Camera.Parameters.html#getVerticalViewAngle%28%29" rel="nofollow">Camera.Parameters.getHorizontalViewAngle</a> seem to be helpful; they give the same values on all of the three devices!

<p>Let's say I've got 64 panels on a JFrame, each one representing a position on the Othello board. After a turn ends, I determine that panels 5 and 6 need to have their colors changed.</p>

<pre><code>for(int i=0; i < array.length; i++){
change the image at array[i]

<p>And, thus, only check for and make changes at the 2, in this example, places I need changed. Saving quite a bit of time writing code.</p>

4,945,135 | 4,945,136 | Launching a modal UINavigationController | <p>I'd like to launch a modal view controller the way one does with 'ABPeoplePickerNavigationController' and that is without having to creating a navigation controller containing the view controller.</p>
<p>Doing something similar yields a blank screen with no title for the navigation bar and there's no associated nib file loaded for the view even though I am invoking the initWithNibName when the 'init' is called.</p>
<p>My controller looks like:</p>
<pre><code>@interface MyViewController : UINavigationController
@implementation MyViewController
- (id)init {
NSLog(@"MyViewController init invoked");
if (self = [super initWithNibName:@"DetailView" bundle:nil]) {
self.title = @"All Things";
}
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
self.title = @"All Things - 2";
}
@end
</code></pre>
<p>When using the AB controller, all you do is:</p>
<pre><code>ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
picker.peoplePickerDelegate = self;
[self presentModalViewController:picker animated:YES];
[picker release];
</code></pre>
<p>ABPeoplePickerNavigationController is declared as:</p>
<pre><code>@interface ABPeoplePickerNavigationController : UINavigationController
</code></pre>
<p>The other way to create a modal view as suggested in Apple's 'View Controller Programming Guide for
iPhone OS':</p>
<pre><code>// Create a regular view controller.
MyViewController *modalViewController = [[[MyViewController alloc] initWithNibName:nil bundle:nil] autorelease];
// Create a navigation controller containing the view controller.
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController];
// Present the navigation controller as a modal view controller on top of an existing navigation controller
[self presentModalViewController:secondNavigationController animated:YES];
</code></pre>
<p>I can create it this way fine (as long as I change the MyViewController to inherit from UIViewController instead of UINavigationController). What else should I be doing to MyViewController to launch the same way as ABPeoplePickerNavigationController? </p>

2,778,072 | 2,778,073 | Memory leakage check of C++ program report in malloc/free? | <p>I suspect my C++ program has a memory leakage problem. If I run it with some high load configuration, it finally get killed by the system (linux). I used top command to monitor the program, it consumes high percentage of memory. Then I get valgrind to help.</p>
<p>It reports that </p>
<pre><code>malloc/free: 18,550,137 allocs, 18,550,137 frees, 1,043,554,226 bytes allocated
</code></pre>
<p>and </p>
<pre><code> all heap blocks were freed -- no leaks are possible".
</code></pre>
<p>In my program I never used malloc/free nor new/delete. All dynamic created objects were created by its constructor. I wonder does program written in c++ always use malloc/free as its lower level memory allocation and deallocation methods? I assume all dynamic memory are allocated from heap. Because linux OS is not aware of which language the program was invented. </p>
<p>It load every executable with the same virtual memory layout -- "TEXT" + "DATA" + "HEAP" + "STACK". Therefore if we let c++/c library function to dynamic allocate memory, it must be from "HEAP" right?</p>
