Android :: Hard-coding Button's Width In Dimension Units

Aug 1, 2010

I've got the hard-coded layout, consisting of buttons, and need to enlarge some of them. I found Button's method setWidth(int value), accepting width in pixels, but I need to set value in dp. So, how can I set dp value in program code?

Android :: Specifying Relative Dimension Of Views On Device Screen Width - Height

Oct 8, 2009

I am writing an android application that has 3 views one below the other. Each view has to be of equal height, depending on the screen size. Each view occupies the full width of the screen. How do you specify in the layout xml that the view has to take up 1/3rd height of the device display height? What would be the appropriate layout to use in this case?

I am working on layout in android XML in which I would like to set a buttons height to match it's width when setup to fill parent.

Android :: Increase Width Of Button Without Stretching Image?

Oct 5, 2010

Kind of a newbie question, I suppose:

I've got a horizontal layout with Button, SeekBar, Button. I'd like the actual space (and active area) of the button to be somewhat wider than the image (a round dot) used for the button.

So I tried setting paddingLeft and paddingRight on the button.

But what I got was the round dot stretched into an oval.

How would I increase the width of the button without stretching the image?

Samsung Captivate :: Search Hard Button Going On By Itself

Sep 29, 2010

I've had my Captivate for a few weeks now. I've noticed since day one that the search button 'hard button' on the lower right of the phone, mysteriously 'pressed itself'. The first few times I figured I pushed it on accident with my pinky or something. That Is Not The Case. I know I'm not going crazy but every once in awhile, the hard button lights will go on and the vibrate (I have vibrate set to on) will go on and the search will pop up. All on it's own. This happens at least 5 times a day. If not more. It doesn't do it on any one specific page, it does it no matter what I'm doing on my phone. Sometimes I'll literally watch it just laying in my hand when my phone is on and the search will pop up.

Motorola Droid :: Hard Keyboard Space Button

Nov 29, 2009

Anyone else notice that the space key on the hard-keyboard is indented, or is this something wrong with mine? I like the keyboard in general, but the space is really annoying. The other keys are all essentially flat, or very slightly curved upwards. The space though is really pretty depressed inwards. I don't think it's worn out, as I really haven't used it much yet.

Motorola Droid X :: Hard Button Functions Via Screen Option

If there's an existing app that offers the same functionality as the default stock options that the hard buttons do.

I'd prefer on-screen icons to 'click' for the

MENU | HOME | BACK | SEARCH

selections that the hard-buttons offer. Do any of the home replacement apps do this? Again, I am not interested in reassigning what the buttons currently do, but looking for any on-screen options instead.

Android :: Combining Two Images Overlaid With Same Dimension?

Sep 9, 2010

I've got a things to do with android, so, I have 2 images,
1. image from camera
2. another image from somewhere

So what I want to achieve is how to combine those image into 1 image, but it's overlapping (just like watermarking the image). The 2nd image should be scaled first into the size of the 1st image(camera) - so they have same dimension, then if the 2nd image pixel is black, don't combine it (so the black means transparent color - on 2nd image). Do you know what is the best way achieve this, can I do this with xor or bitwise?

Android :: Force LinearLayout To Draw Objects In More Than One Dimension?

Sep 28, 2010

I need to populate a View with a data from adapter which contains some number of strings. The problem is that I don't know how many of the strings will be there. So my idea was to use LinearLayout to store data. But even if I reserve enough space for this data (eventually I will draw it in ScrollView), LinearLayout use only horizontal perspective (drawing Strings to the end of line), and not uses additional space beyond.
My intention is to draw to the end of line, and draw next line... till end of data.

Android :: Gallery Item Width Vs Gallery Width

Jan 10, 2010

I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

Android :: Isolating Units / Writing Tests

Jul 23, 2010

My project has the run-of-the-mill HTTP calls to fetch XML files, parsing the XML files, and creating domain objects. Those objects are later used in the actions and services of the Android app, I'd like to isolate that code. I also want to write tests for it. What are some good ways of doing this? Creating an Android Library doesn't seem appropriate. The tests would have to be in a separate project. And there are no services or activities in the extracted HTTP and XML related code. So the test suite doesn't have to be an Android test suite, it could be regular JUnit tests.

Android :: Maximum Texture Units - Emulator Setup

Apr 30, 2010

this is just an issue with how the emulator is setup, but I'm not sure.

I'm (natively) calling this:

int maxt = 0;
glGetIntegerv(GL_MAX_TEXTURE_UNITS, &maxt);
__android_log_print(ANDROID_LOG_VERBOSE, "Native", "Max textures %d", maxt);

This only outputs 2... could it be possible that I'm going to be allowed only 2 textures? That seems impossible... GL_MAX_TEXTURE_SIZE reports 4096 which is more than enough. I suppose you could lay everything out on a couple of 4096x 4096 images (seems a bit crazy) but anyway... Am I just running into one of things that will be different per phone processor?

Android :: Audio Stream Trans Coding?

Jan 11, 2010

Let me first state that I do not know Java. I'm a .NET developer with solid C# skills, but I'm actually attempting to learn Java and the Android SDK at the same time (I know it's probably not ideal, but oh well, I'm adventurous :)) That said, my end goal is to write a streaming media player for Android that can accept Windows Media streams. I'm okay with restricting myself to Android 2.0 and greater if I need to. My current device is a Motorola Droid running Android 2.0.1. There is one online radio service I listen to religiously on my PC that only offers Windows Media streaming, and I'd like to transcode the stream so my Android device can play it.

Is such a thing possible? If so, would it be feasible (i.e., would it be too CPU intensive and kill the battery)? Should I be looking into doing this with the NDK in native code instead of Java? I'm not opposed to writing some sort of service in between that runs on a desktop computer (even in C#), but ideally I'd like to explore purely device-based options first. Where should I start?

Android :: Chaning Coding Style Due To GC Performance?

Apr 7, 2010

I keep hearing that Android applications should try to limit the number of objects created in order to reduce the workload on the garbage collector. It makes sense that you may not want to created massive numbers of objects to track on a limited memory footprint, for example on a traditional server application created 100,000 objects within a few seconds would not be unheard of.

The problem is how far should I take this? I've seen tons of examples of Android applications relying on static state in order supposedly "speed things up". Does increasing the number of instances that need to be garbage collected from dozens to hundreds really make that big of a difference? I can imagine changing my coding style to now created hundreds of thousands of objects like you might have on a full-blown Java-EE server but relying on a bunch of static state to (supposedly) reduce the number of objects to be garbage collected seems odd.

How much is it really necessary to change your coding style in order to create performance Android apps?

Android :: OpenGL Coding - Emulator Doesn't Work

May 26, 2009

After spending the better half of this day getting my HTC Magic to work in developer mode, I've now found that some of my frist openGL coding attempts that appeared to work fine in the emulator doesn't work as expected on the device. I've narrowed this down to glColorf(r, g, b, a) not working as expected on the device itself. The provided OpenGL samples do work though. So for example, after modifying Cube.java from the samples to the below code I find that I get the expected grey square on the emulator but a blank white screen (background fill colour) on the device.

class Cube { public Cube() { int one = 0x10000; int vertices[] = { -one, -one, -one, one, one, -one, one, one, };
// Buffers to be passed to gl*Pointer() functions // must be direct, i.e., they must be placed on the // native heap where the garbage collector cannot // move them. // // Buffers with multi-byte datatypes (e.g., short, int, float) // must have their byte order set to native order
ByteBuffer vbb = ByteBuffer.allocateDirect(vertices.length*4); vbb.order(ByteOrder.nativeOrder()); mVertexBuffer = vbb.asIntBuffer(); mVertexBuffer.put(vertices); mVertexBuffer.position(0); }
public void draw(GL10 gl) { gl.glFrontFace(GL10.GL_CW); gl.glVertexPointer(2, gl.GL_FIXED, 0, mVertexBuffer); gl.glColor4f(0.5f, 0.5f, 0.5f, 0.5f); gl.glDrawArrays(GL10.GL_TRIANGLE_STRIP, 0, 4); }
