I've started a little game, and so far I'm moving a little guy with onKeyDown() and the DPAD from Android Emulator. Now what I want to do is to add 4 buttons on the screen (like in a GAMEBOY emulator for example) and these buttons should move my little guy. With a clickListener and onClick() (or touchListener and onTouch()), it's ok for one move but how to do if I want that my little guy continues moving when I stay clicked on the button ??? Buttons are enough or should I make a 4 arrows soft keyboard or anything else?

I tracked the behaviour of the different screen sizes when I increased the position of a graphic by 10 pixel. Unfortunately happened what I already thought. When the display is bigger, I'm able move a graphic a lot of times more to get to the bottom of the screen. So the ratio between the graphic and its environment is not correct anymore (so not 10 pixel as on normal screen) although the change of the graphic on the different screens looks correct (On big screen it is bigger, on small screens it is smaller). When I move the graphic from the top of the screen to the bottom, I can move that on 480x800 about 65 times, on 480x854 70 times, and on the 320x480 screen only about 25 times. So the target must be to calculate the right ratio so that 10 pixels on the small screen are 17 pixel (or sth. similar) on big screens. What approaches do I have to do that? I already thought about getting the value of res.getConfiguration().screenLayout to know if I have a small, normal, or big size to be able to calculate anyhow the right ratio, but this both seems to be pretty cumbersome and moreover I get values from res.getConfiguration().screenLayout I can't explain. I launched 6 emulator instances and got the following values from res.getConfiguration().screenLayout:
240x320 QVGA low density: 17 320x480 HVGA medium density: 18 480x854 WVGA high density: 34 480x800 WVGA high density: 34 240x400 WQVGA low density: 34 240x432 WQVGA low density: 266435490 (yes, I really get this value!)
This approach seems to be useless because I cannot even distinguish between 480x854 and 480x800, much less of the last value which seems to be corrupt.
How can I solve it to move a graphic on the different screens with the right ratio? How do game developers solve this when they support all screens?

is there a way to move the icons without having to remove them and then pick a new place? If not - why with the nice slide functionality, can you not just slide them around on the same screen or the the next?

im having similar issues that others have reported of their screens moving on their own. if im on my home screen, the pages will flip to the right on its own. this isnt the only place it happens. one example is when im trying to enter text. the selection will move away from the text box the the send button. do i have a defective screen? i installed a zagg screen protector on the phone and its slightly overlapping on the top left side of the optical track. could it be that? should i take it to verizon?

It seems there's a trick that I'm missing because I'm only successful 10% of the time I want to move an icon from one screen to the other. Most of the time I have to delete the icon, swipe to next screen, then add it again.

When you get past the security and are on the main Sense UI screen, does it sometimes move to the screen to the left or right of whatever the main screen is on its own? If so anyone know how to cure this problem? I've only seen it occur when on the main screen but no where else.

on the droid x, i found this to be VERY simple. press and hold the icon, then once it is unmounted slide to left of right. once the green "highlight" appears on that side, the sscreen moves as well as the icon.i had the original droid and dont think it was this easy, though im not sure i ever tried.

I have purchased a HTC Legend about 3 weeks ago and am very satisfied with this cell phone. My only concern is related to the reliability of the "mechanical keys" (Home, Menu, Return and Search) . I have interacted a lot with my cell phone and verified that I need to press the Home button many and many times to leave an application in order to go back to the main menu to get access to another application.
I would like to know if there is some application to create an icon in the Notification bar (on the top of the touch screen) in order to return to Home screen. This seems to be an interesting solution because the Notification bar is always active, regardless of the application that is running. In this case, the user could access it through the touch screen and avoid using the mechanical keys all the time, so that the user would not need to worry with the life time of the mechanical keys.

Has anyone else noticed their icons moving around [by themselves] on the home screen? A couple of days ago, the "Phone" icon suddenly appears on the left-most home screen rather than on the center one. Today, I discovered that I had 2 Gmail icons on my home screen. I thought that it was my imagination, but this has happened a couple of other times.

For example, I can scroll a page but when I stop and hold my finger on the screen, it moves about very jittery even though my finger is not even moving. It can be annoying at times when I want the screen to be steady.
Has anyone else had this problem? BTW, I do have a clear screen protector on my screen, could that be part of the problem?

My app keeps force closing before it starts, eclipse returns no errors in my code and my xml is good.
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class main extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button myScanButton = (Button) findViewById(R.id.myScanButton); myScanButton.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} } );
} EditText totalbox = (EditText) findViewById(R.id.totalbox);
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) { if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
// Handle successful scan totalbox.setText(contents)
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel totalbox.setText("@string/bummer");
} } } }
Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.

I want to add home screen shortcuts to individual chat rooms, in my app.
Here's my code to do so:
CODE:.............
When I go to add the shortcut to my home screen, I get a Force Close, not on my own process, but on com.android.acore(!). I've run the debugger and verified that my code gets executed all the way to the call to finish().
If I do this instead for the EXTRA_SHORTCUT_ICON:
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, R.drawable.icon);
It works fine and places the shortcut, and the shortcut behaves correctly -- but of course the shortcut has the stock Android icon, not mine, since this isn't the proper way to specify the icon.
When I look at the source code of other apps that have done this, and at the one example of it in the official Android reference area, my code looks identical. My icon's a standard 48x48 png that I use for the app's main icon, without problems. I've verified this problem on an emulator running stock 1.6, haven't tested other versions.

I am designing a home screen widget. I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels.Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device.I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing?

Hey everyone, I'm sort of new to this but I figured I'd give it a shot to see if anyone might have an answer.
This happens fairly frequently actually, but I'll be in an app (any app - it's not really particular) and sometimes it'll just randomly shut me out of it and return to the home screen. As it does this, the home button blinks and vibrates incessantly until I hold down on it - at which point it brings up a sort of mini-list of six apps (the last six apps I've opened, I suppose). Once I clear out of that list, then the phone resumes working normally.
I initially thought it had something to do with the memory and running too many apps at once, so I downloaded Advance Task Killer and run that occasionally...only to find the same problem occurring, sometimes RIGHT after I kill all the apps.
Has anyone else had this happen? Can anyone help me out?

Facebook is a huge application, as such I've had it installed in /system for a while now, however last night I decided I would upgrade to Facebook 2.0, when moving it to system the app force closes upon start.
I've tried totally uninstalling/reinstalling it, clearing data/cache/dalvik to no avail, any pointers? or is this simply how it is now?
Hardware: HTC Desire bravo
OS: CyanogenMod-7.2.0.1-bravo

Is there a way to disable the auto screen locking function when I close my cover?
I bought a couple of cheap case covers from China and as far as I understand they might not have the right material which causes the IR to be reflected instead of being absorbed.
I don't mind it locking really, aside from maybe a bigger battery consumage, since I often hear it locking itself while in my pocket.
No, my main problem is, with some of the covers, if I flip the front cover side to the back so I can hold the phone easily, it locks.
For example, the 2 I have on me, the leather one locks if I flip it over, the plastic one doesn't.
Really I'd like to disable the function alltogether, I prefer locking it myself together with the trusty 30s idle lock.
How do I disable auto locking when closing case cover.
