[android-developers] How does the 3D objects get touch events?

[quill]

HI all,
I am writing a game using OPENGL, there are several 3D objects in my
surfaceview.
My question is:
Should each 3D object implement view in order to get touch events?
Or there is other way to do this?

Thank you!

[android-developers] ToggleButton - how to implement iPhone-style ToggleButton?

[zhangxiyuan]

Hi,

I think Android does not provide iPhone style toggle button?
Look at the picture below, when I just want to set ON|OFF for some
settings, I think the iPhone style and Android style ToggleButton are
both OK for me, but I have an application, I want to migrate it from
iPhone SDK -> Android Platform?

Can someone give me a hint about how to do that?

P.S:
Because the iPhone style ToggleButton has a slider in it, so it
supports drag&drop, Do I have to implement the TouchEvent listener?

Thanks.

iPhone style ToggleButton:
###OFF
ON

[android-developers] Re: OpenGL

[Nightwolf]

I have no answer to your question. Just want to add that there are
other differences between emulator and real device - emulator works OK
with non power of two texture dimensions and supports drawing lines
with width more than 1.

[android-developers] Re: Conversion to Davik failed with error 1

[Francois]

Hello all,

I am answering to myself here.

If I create a new 1.5 project it works. No more errors.
If I create a new 1.1 project it does not work, I get the error.

So I think there is definitively a bug in the 1.1 platform kit.

Hope this can help anyone facing the same problem!

i found a solution of this problem:
in the onSensorChanged function
public void onSensorChanged(int sensor, float[] values) {
/*
that is the normal code with have the problem
float x=values[0];
float y=values[1];
float z=values[2];
which 0,1,2 is the Accelerometer values based on the orientation and this
give an error some time in the landscape orientation
*/
/*
this is the correct code
*/
float tmpX=values[3];
float tmpY=values[4];
float z=values[5];
 /*
where 3,4,5 is the PORTRAIT screen orientation
so if u want to use it in the land scape orientation swap x and y
*/
float x = -1*tmpY;
float y = x;

If thread A exits, thread B will continue running.

If an exception occurs in thread A, whether thread B continues running
depends on what catches that exception, and whether the process is
terminated as a result. Ideally, you catch your own exceptions, and as
such thread A and thread B will still be running.

There are many ways to achieve your desired pattern, mostly involving
classes in java.util.concurrent.

For example:

-- You can use an AtomicBoolean to set a flag from thread A that thread
B monitors to know when to shut down

-- You can have thread B pull work off a LinkedBlockingQueue, with a
special "kill" piece of working telling thread B to close up

However, better than all of that is to switch to using Android 1.5's
AsyncTask, if possible, because you get all the benefits of background
threads without having to manage them yourself.

[android-developers] Dialog (built using AlertDialog.Builder) not complete when showing dialog in runOnUiThread

[TjerkW]

I have a game activity in which i have a dialog which is created in
the onCreateDialog method of the activity:

case VICTORY_DIALOG:

String[] items={"Next Level", "Play Again", 
"Exit"};

AlertDialog.Builder builder = new 
AlertDialog.Builder(this);
builder.setMessage("You won!")
.setCancelable(false)
.setItems(items, new 
DialogInterface.OnClickListener() {
public void onClick(DialogInterface 
dialog, int id) {
if(id==0) {

SpaceWarsActivity.this.nextLevel();
} else if(id==1) {

SpaceWarsActivity.this.loadGame();
} else if(id==2) {

SpaceWarsActivity.this.onFinishGame();
}
}
});
dialog=builder.create();
break;


When the game ends i open this dialog from the game thread (not the ui
thread) with the following code:

activity.runOnUiThread(new 
Runnable() {
public void run() {

activity.showDialog(VICTORY_DIALOG);
}
});

However... the dialog is just a small empty rectangle. No title, no
items, nothing!
The buttons (setPositiveButton,setNegativeButton,setNeutralButton) are
working though.

Wat am i doing wrong?

Thanks in advance

[android-developers] Re: sub-thread issue.

[TjerkW]

I created a game which also requires a gameloop thread.
I communicate with the thread simply by using getters and setters.
But that requires that the other threads has a the new thread as a
member instance.

I use the AsyncTask for loading levels, not for the game loop.

[android-developers] Question about SMS processing

[iloveblue]

Hello Everyone:

I am doing a basic handling of the SMS, and I have complete the
functions of send and receive the SMS, but I want to do them better.

About receiving the SMS, I have some question, I have one Application
on the Android which I called MyApp, it has a broadcastReceiver
extended class which will handle while the SMS comes, and pickup some
"special" SMS which is used in MyApp, such as "SMSMYAPP:xx", then
I think it is useless to the system SMS receiver. And so I donot want
the system SMS receiver to get this SMS, and show the notification
about this comes. But I cannot find any useful information about donot
give the SMS to the system SMS receiver, I've tried abortBroadcast()
but it shows errors in Logcat.

Can anyone give some suggestion about this? Or just tell me it is
impossible to do this for some security questions? Thanks very much. I
have look for this for days. Any words could be help.

[android-developers] Re: How does the 3D objects get touch events?

[Anton]

Usually this is solved by having ray-object intersection code for
all of your geometry.  If your 3D objects are all polygon meshes then
you need ray-polygon intersection code.  You then generate a ray from
the eye point through the screen point that the user is touching.
This ray is then tested against all of your geometry to find the
closest hit.  That tells you what object was hit as well as where on
the object.  Of coarse, if your scene has many objects with lots of
polygons to test you will want to use some sort of spacial data
structure to speed up the hit testing.  However, since you only need
it to run at "human speeds" you can get away with doing a lot of hit
tests before you have to resort to acceleration structures.  One
simple thing to do is to hit test the objects bounding volumes
(spheres are particularly easy).  That lets you not test the
individual polygons in objects that fail the bounding volume test.  If
you have scripts for your objects that need to receive touch events
you can pass the event along to the object once you've determined
which object is hit.

[android-developers] Re: PNG transparency and OpenGL ES

[djp]

There some nice tricks that you can do with a separated alpha. For
example, you can draw an object with certain parts opaque and other
parts accumulated without changing blending factors.

There is a similar problem on iPhone, but you can solve it by using a
custom PNG decoder. But so far I was unable to find any solution for
Android. It's not mentioned in the documentation either.

Still, there is a hope that I'm just missing something :) Any clue
from Android devs?

If you are using LinearLayout, set android:layout_height="0px" and
android:layout_weight="1" on the ListView, and set
android:layout_height="wrap_content" on the Button. That will give the
Button enough space to show itself and give the ListView the rest of the
space.

If you are on Android 1.5, check and make sure your project has the
proper target. If you are using Ant to build, you'll find a
default.properties file that should contain the line:

target=Google Inc.:Google APIs:3

I'm not sure what the equivalent is in Eclipse.

If you are targeting something else (e.g., 2), you won't have the Google
Maps add-on.

[android-developers] Re: Dialog (built using AlertDialog.Builder) not complete when showing dialog in runOnUiThread

[TjerkW]

Ok i solved it myself.

I use setMessage together with setItems.. this does not work
One should use setTitle in stead of setMessage.

I think the builder show throw an exception if somebody uses
a illegal combination of parts (in my case: message + items)

Anyway its a small issue, but a nasty bug if you dont see it :-)

1.0r2?

That's three SDK releases ago (1.1r1, 1.5r1, 1.5r2), and my memory is
fuzzy on the details of getting maps to work back then, so I'm not going
to be a ton of help.

Sorry!

If I understand the issue correctly, Android has always behaved this way.

Links in WebView, by default, open up the Browser application (more
accurately, they call startActivity() on an Intent with an http://
scheme, which usually results in the Browser opening on the URL). If you
want to prevent that, you need to use WebViewClient and
shouldOverrideUrlLoading(). That behavior has existed since at least
Android M5 (last summer).

If I am misunderstanding the issue, I apologize.

It seemed there is no such a thing

"android.net.conn.BACKGROUND_DATA_SETTING_CHANGED" aviliable in SDK

[android-developers] Re: how make the ListView be above the button

[Al]

I used a RelativeLayout for something similar. Specify the listview in
xml using @android:id/list as the id, and then define the button with
the correct layout settings to position it below the listview (and
align it to the bottom of the screen). Giving the button the following
property: android:layout_below="@android:id/list", should help get it
into place.

Then in code, use a class which extends ListActivity, call
setContentView(R.layout.my_layout), use findViewById to find the
listView and set an adapter or something to populate it.

Hi,

There is none yet. That is why we posted the job, to try and get a

[android-developers] Re: Unable to set sd card parameter

[Roman]

Which platform version are you using right now? In case of version 1.5
you should be able to select in the target tab the AVD which has a
sdcard. If you don't have such an AVD you might want to create it
manually.

When you select "run configuration", switch to tab "target" and select
AVD Manager you can create an AVD with SD-Card. Use this AVD later
when you use "run configuration".

[android-developers] AutoCompleteTextView and AdapterView.onItemClickListener with onscreen keyboard not working

[Ty]

I have an app that has been working great until I changed the app to
use sensor and tested in 1.5.  When turning the phone sideways with
keyboard closed, I click on the autoCompleteTextView EditText I have
setup.  This brings up the on screen keyboard.  Great.  I start typing
a name and get a dropdown list of say 5 names to select from.  Great.
This dropdown is sideways not vertical.  This is new and I am assuming
this has to do with the onscreen keyboard.  I select one of those
names and it does a callback to my onItemClickListener.  Great.  So
far so good.

Problem is that the View returned is always null.  Always.

If I change the phone back to portrait and do the same all is good and
I can safely rely on the view returned to the listener.

If I leave the phone in landscape but open the physical keyboard then
it works just fine.

Why would the view be null with this new horizontal drop-down?  Is
there a different type of listener I should use.  Should I be setting
something differently in my CursorAdapter?  Any help is much
appreciated.

[android-developers] SubMenu, Dialogs and ActivityGroup

[skyman]

Hello,

I have 6 options to put in options Menu, but 3 of them are not so
important and i want to hide them in submenu.
All of my Activities are started from one ActivityGroup which creates
Menu on MENU button press.
Problem is that when I open SubMenu or Dialog (which is created and
displayed by ActivityGroup) my current foreground activity makes
onPause, onStop and onDestroy, and when I close this submenu (using
"back" key) or dialog (by "ok" button for ex.) I don't have any
response (onCreate, onResume) from any of my activities registered in
LocalActivityManager.

Is it a bug?

[android-developers] Re: orientation change handling on widgets

[Jeff Sharkey]

For AppWidgets, you can use a separate layout for portrait versus
landscape.  If you're doing custom rendering, you could send both
bitmaps across the RemoteViews if they aren't too heavy.  (With
separate id's for each orientation, that would be GONE as needed.)

Hello Oceanedge,
I'd like to get back to one of your former questions:

That is why. :)
(Sorry, I don't feel like repeating the things Miško Hevery explains

spend some minutes reading it. It's definitely worth it.)

Hi,
If you want to add a new item in the listview,you could dynamic create
a new adapter and load it in the listview.

Just add the new items to the adapter, or the data source that backs up
the adapter (if it's a CursorAdapter).

U...

1. Experiment with MP3 or Ogg Vorbis, to see if you can get your audio
clips to be much smaller, while still retaining acceptable quality. I
suspect either of those formats will work much better than .WAV.

2. Give the users options of downloading the whole set of audio clips at
once (to their SD card) or downloading them on the fly as needed
(requires Internet connection).

[android-developers] Can't figure out how to use SurfaceView properly, nothing is drawn

[klirr]

I had it working with a normal View but that is to slow. I was told to
use SurfaceView but can't figure out how to use OnKey with it and if I
should use onDraw or draw?
And how do I pass stuff to draw? does it happen automatically?


package com.android.WWS;

import android.app.Activity;
import android.content.Context;
import android.graphics.*;
import android.os.Bundle;
import android.view.SurfaceView;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnKeyListener;

public class WWS extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new GameView(this));
}

private static class GameView extends SurfaceView implements
OnKeyListener {
private Paint mPaint = new Paint();
private int x;
private int y;

public GameView(Context context) {
super(context);
x = 135;
y = 303;
setFocusable(true);
requestFocus();
}

@Override
public void onDraw(Canvas canvas) {
Paint paint = mPaint;
canvas.translate(10, 10);
canvas.drawColor(Color.rgb(184,134,11));
paint.setColor(Color.rgb(107,142,35));
paint.setStrokeWidth(1);
canvas.drawRect(x, y, x+30, y+7, paint);
canvas.drawRect(x+10, y+7, x+20, y+27, paint);
canvas.drawRect(x+5, y+27, x+25, y+32, paint);
}

public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DPAD_UP) {
y -= 3;
} else if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) {
x -= 3;
} else if (keyCode == KeyEvent.KEYCODE_DPAD_DOWN) {
y += 3;
} else if (keyCode == KeyEvent.KEYCODE_DPAD_RIGHT) {
x += 3;
}
return true;
}

}

}

[android-developers] How to set data roaming and GSM/AUTO Mode

[Augustin.CL]

Dear All,

   I want to adjust some settings to disable/enable data
roaming and switch GSM/AUTO mode as the functions provided by
Settings.apk(Settings -> Wireless controls -> Mobile networks -> "Data
roaming"/"Use only 2G networks").
   I know there is a way to get the current setting of data
roaming through the api android.provider.Settings.Secure.DATA_ROAMING.
But I don't know if I could change here to control the usage of Data
roaming. If it is nothing but the status of data roaming. Changing
here will cause the state of the system inconsistent.
   Although I could find the api related to Data roaming, I
can't find any thing about switching GSM/AUTO mode except for some
internal api.
   Is there anyone having some related ideas or experiences?
Please give me some suggestions.

BTW, before this discussion I has posted an old related discussion,
but I can't find it from the groups. Does this mean the system miss
the discussion I posted?

[android-developers] Re: How does the 3D objects get touch events?

[Anton]

A google search for "Ray Intersection Tests" gives a number of
good links on how to do this.  Also, Peter Shirley's book "Realistic
Ray Tracing" is a fantastic introduction to the subject.  But I have
no example code on hand that could be used on Android.

[android-developers] HTC Ion Problem

[Bobbie]

I got back from Google I/O 2009 with the "HTC Ion" phone that they
gave out to everyone.  The phone was given to us fully unlocked, so I
am using it on Centennial Wireless' network.  In the system settings
though it says my phone number is "unknown" but I can make and receive
calls without any problems.  The issue I'm running into is that I
can't get the user's phone number without this data.  Anyone have any
suggestions on how to remedy this problem?

[android-developers] images render very differently

[Nate]

I am using OpenGL ES and drawing a triangle strip with 4 vertices. The
texture I'm drawing was loaded from a PNG using
BitmapFactory.decodeStream. I'm confused as to why my images look so
bad. I took a screenshot and made the following image, which shows the
on-device rendering on top and the actual image on bottom:

http://n4te.com/temp/imgDiff.png

Any idea why there is a difference? I have tried a bunch of different
settings but I can't keep it from looking bad.

Thanks!
