问题 I have a popular drawing tablet that I connect to my PC with USB. Once connected, the tablet detects hand movements and manipulates the pointer accordingly. Somewhere, the tablet is transmitting this data to my computer. My goal is to intercept these transmissions and manipulate the mouse after I process the data. The buzzwords I have found are: device drivers and HID , but I haven't been able to piece together much more than that. Assuming this is possible, I have a few questions: How is

Starting out in Android tablet development

自古美人都是妖i 提交于 2019-12-03 00:38:39
I recently bought a Motorola XOOM tablet to develop Android apps on. I'm running into major problems with finding resources to learn from. I know Java. The Android Dev Guide sample codes are almost all dependent on a keyboard or won't run on my XOOM . Are there any suggested places to start learning Android development, other than the Android Dev guide? Krishna You will be creating a new avd config to specify the tablet screen size, memory constraints, SDcard size, etc. I believe that most of that can be achieved by just creating a new avd and changing the parameters in avd manager. Although

CSS Media query landscape android soft keyboard

谁说我不能喝 提交于 2019-12-02 21:06:11
I'm working on a web application for tablets(for android and ios) and I'm facing a problem which is giving me trouble for 2 days already. The problem is that on android when you are in portrait mode and for example you focus an input field so the soft keyboard pops up the css media query orientation changes to landscape. I already have read this question : CSS Media Query - Soft-keyboard breaks css orientation rules - alternative solution? and came up with this : var is_keyboard = false; var is_landscape = false; var initial_screen_size = window.innerHeight; window.addEventListener("resize",

Converting GWT Click Events to Touch Events

时光怂恿深爱的人放手 提交于 2019-12-02 20:58:08
I am working on a Big Project and i have a lot of GWT code written. Now i am working on making the project fully compatible with Tablets like iPad and Android Tablets. As a part of this, i have noticed that touch devices takes 300ms delay to handle click events. In this project, writing touch events again is a very tedious task. I have done a lot of researches in this and found the Google Fast Buttons API used in Google Voice Application. I tried that and its working good but requires a lot of coding and JSNI. My question is, Is there anything else available in your knowledge to easily

问题 I have developed an Android application for both handsets and tablets. It has been running in both emulators. While I am running in the tablet emulator the size of widgets are filling the screen. What should I do solve this conflict? 回答1: You can make two different layouts for handlet and tablets in res/layout (for handlet) and res/layout-large (for tablet). Layout file name must be same. More explanation and other methods you can found here: http://developer.android.com/guide/practices

NullPointException with getActionBar

孤人 提交于 2019-12-02 18:22:28
问题 I have a really strange behaviour with my tablet interface (Android > 3). When I launch it, it's like a Android 2* interface with the title at the bottom. And of course when I call the getActionBar() it returns a null. My min-sdk & target-sdk are well set and I use the SDK Android 3.0 (11). Where am I wrong ? public class MainScreenActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.mainlayout);

Is it possible to run R from a tablet using Honeycomb (Android 3.0)?

拟墨画扇 提交于 2019-12-02 17:38:58
I have a Xoom tablet and it would be great if I could run statistical analysis using R on it. As far as I know it is not possible to use R on iPad due to license problems (GPl x iTunes etc.) and a lack of compiler for Fortran in the Apple tablet. But what about tablets using android? Arguably, the GPL issue is not a problem, so any help here on how to use R on my tablet? At some point, smartphones and tablets will have browsers capable enough to run RStudio in its server mode via the browser. Currently, the latter demands too much in terms of newer GWT, Javascricpt, ... magic that it remains

こ雲淡風輕ζ 提交于 2019-12-02 15:38:54
I was looking into the tablet design of Gmail application. In that Navigation Drawer implementation is different from others. I have attached image for your reference. And also when I expand the the drawer it should happen like normal navigation drawer behavior. I would like to implement in the same way.

ProgressBar in an ActionBar, like GMail app with Refresh

丶灬走出姿态 提交于 2019-12-02 15:37:31
I would like to do the same thing than the GMail application on Honeycomb tablets. When you click on the Refresh button, the icon is replaced by a ProgressBar. How can I do this? Thanks Ok, I tried what Cailean suggested but it didn't work for me. Every time I want to revert indeterminate progress to the original button it becomes unclickable, I used this layout for the progress (actionbar_refresh_progress.xml) <?xml version="1.0" encoding="utf-8"?> <ProgressBar xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="32dp" android:layout_height="32dp" android:layout
