  • Starting an HTML canvas game with no graphics skills

    - by Jacob
    I want to do some hobby game development, but I have some unfortunate handicaps that have me stuck in indecision; I have no artistic talent, and I also have no experience with 3D graphics. But this is just a hobby project that might not go anywhere, so I want to develop the stuff I care about; if the game shows good potential, my graphic "stubs" can be replaced with something more sophisticated. I do, however, want my graphics engine to render something approximate to the end goal. The game is tile-based, with each tile being a square. Each tile also has an elevation. My target platform (subject to modification) is JavaScript rendering to the HTML 5 canvas, either with a 2D or WebGL context. My question to those of you with game development experience is whether it's easier to develop an isometric game using a 2D graphics engine and sprites or a 3D game using rudimentary 3D primitives and basic textures? I realize that there are limitations to isometric projection, but if it makes developing my throwaway graphics engine easier, I'm OK with the visual warts that would be introduced. Or is representing a 3D world with an actual 3D engine easier?

  • Need Guidance Making HTML5 Canvas Game Engine

    - by Scriptonaut
    So I have some free time this winter break and want to build a simple 2d HTML5 canvas game engine. Mostly a physics engine that will dictate the way objects move and interact(collisions, etc). I made a basic game here: http://caidenhome.com/HTML%205/pong.html and would like to make more, and thought that this would be a good reason to make a simple framework for this stuff. Here are some questions: Does the scripting language have to be Javascript? What about Ruby? I will probably write it with jQuery because of the selecting powers, but I'm curious either way. Are there any great guides you guys know of? I want a fast guide that will help me bust out this engine sometime in the next 2 weeks, hopefully sooner. What are some good conventions I should be aware of? What's the best way to get sound? At the moment I'm using something like this: var audioElement = document.createElement('audio'); audioElement.setAttribute('src', 'paddle_col.wav'); audioElement.load(); I'm interested in making this engine lightweight and extremely efficient, I will do whatever it takes to get great speeds and processing power. I know this question is fairly vague, but I just need a push in the right direction. Thanks :)

  • canvas tile grid, hover effects, single tilesheet, etc

    - by user121730
    I'm currently in the process of building both the client and server side of an html5, canvas, and WebSocket game. This is what I have thus far for the client: http://jsfiddle.net/dDmTf/7/ Current obstacles The hover effect has no idea what to put back after the mouse leaves. Currently it's just drawing a "void" tile, but I can't figure out how to redraw a single tile without redrawing the whole map. How would I go about storing multiple layers within the map variable? I was considering just using a multi-dimensional array for each layer (similar to what you see as the current array), and just iterating through it, but is that really an efficient way of doing it? Side note The tile sheet being used for the jsfiddle display is only for development. I'll be replacing it as things progress in the engine. I hope you can help! Hopefully you guys can help me, I've been struggling to get through things, since I'm learning how things kind of stuff works as I go. If you guys have any pointers for my JavaScript, feel free. As I'm more or less learning advanced usage as I go, I'm sure I'm doing plenty of things wrong. Note: I will continue to update this post as the engine improves, but updating the jsfiddle link and updating the obstacles list by striking things that have been solved, or adding additions. Thanks!

  • HTML5 Canvas Converting between cartesian and isometric coordinates

    - by Amir
    I'm having issues wrapping my head around the Cartesian to Isometric coordinate conversion in HTML5 canvas. As I understand it, the process is two fold: (1) Scale down the y-axis by 0.5, i.e. ctx.scale(1,0.5); or ctx.setTransform(1,0,0,0.5,0,0); This supposedly produces the following matrix: [x; y] x [1, 0; 0, 0.5] (2) Rotate the context by 45 degrees, i.e. ctx.rotate(Math.PI/4); This should produce the following matrix: [x; y] x [cos(45), -sin(45); sin(45), cos(45)] This (somehow) results in the final matrix of ctx.setTransform(2,-1,1,0.5,0,0); which I cannot seem to understand... How is this matrix derived? I cannot seem to produce this matrix by multiplying the scaling and rotation matrices produced earlier... Also, if I write out the equation for the final transformation matrix, I get: newX = 2x + y newY = -x + y/2 But this doesn't seem to be correct. For example, the following code draws an isometric tile at cartesian coordinates (500, 100). ctx.setTransform(2,-1,1,0.5,0,0); ctx.fillRect(500, 100, width*2, height); When I check the result on the screen, the actual coordinates are (285, 215) which do not satisfy the equations I produced earlier... So what is going on here? I would be very grateful if you could: (1) Help me understand how the final isometric transformation matrix is derived; (2) Help me produce the correct equation for finding the on-screen coordinates of an isometric projection. Many thanks and kind regards

  • Recreating Doodle Jump in Canvas - Platforms spawning out of reach

    - by kushsolitary
    I have started to recreate Doodle Jump in HTML using Canvas. Here's my current progress. As you can see, if you play it for a few seconds, some platforms will be out of the player's reach. I don't know why is this happening. Here's the code which is responsible for the re-spawning of platforms. //Movement of player affected by gravity if(player.y > (height / 2) - (player.height / 2)) { player.y += player.vy; player.vy += gravity; } else { for(var i = 0; i < platforms.length; i++) { var p = platforms[i]; if(player.vy < 0) { p.y -= player.vy; player.vy += 0.08; } if(p.y > height) { position = 0; var h = p.y; platforms[i] = new Platform(); } if(player.vy >= 0) { player.y += player.vy; player.vy += gravity; } } } Also, here's the platform class. //Platform class function Platform(y) { this.image = new Image(); this.image.src = platformImg; this.width = 105; this.height = 25; this.x = Math.random() * (width - this.width); this.y = y || position; position += height / platformCount; //Function to draw it this.draw = function() { try { ctx.drawImage(this.image, this.x, this.y, this.width, this.height); } catch(e) {} }; } You can also see the whole code on the link I provided. Also, when a platform goes out of the view port, the jump animation becomes quirky. I am still trying to find out what's causing this but can't find any solution.

  • Animating sprites in HTML5 canvas

    - by fnx
    I'm creating a 2D platformer game with HTML5 canvas and javascript. I'm having a bit of a struggle with animations. Currently I animate by getting preloaded images from an array, and the code is really simple, in player.update() I call a function that does this: var animLength = this.animations[id].length; this.counter++; this.counter %= 3; if (this.counter == 2) this.spriteCounter++; this.spriteCounter %= animLength; return this.animations[id][this.spriteCounter]; There are a couple of problems with this one: When the player does 2 actions that require animating at the same time, animation speed doubles. Apparently this.counter++ is working twice at the same time. I imagine that if I start animating multiple sprites with this, the animation speed will multiply by the amount of sprites. Other issue is that I couldn't make the animation run only once instead of looping while key is held down. Someone told me that I should create a function Animation(animation id, isLooped boolean) and the use something like player.sprite = new Animation("explode", false) but I don't know how to make it work. Yes I'm a noob... :)

  • Android project problem

    - by qwerty
    Hello, here I uploaded my Android project made in Eclipse. The idea is that i have a service, which computes the sum of two random numbers. But when i press the OK Button, i don't see the result in that edit box... why? What i'm doing wrong? Please help Thanks! EDIT: The code: //service class package service; import java.util.Random; import com.android.AplicatieSuma; import android.widget.EditText; import android.widget.TextView; public class ServiciuSuma { public ServiciuSuma() { } public int CalculateSum() { Random generator=new Random(); int n=generator.nextInt(); int m=generator.nextInt(); return n+m; } } The Application class: package com.android; import android.app.*; import service.*; public class ApplicationSum extends Application { public ServiciuSuma service = new ServiciuSuma(); } and the main Activity class: package com.android; import com.android.R; import android.app.Activity; import android.content.Intent; import android.graphics.Color; import android.graphics.PorterDuffColorFilter; import android.graphics.drawable.Drawable; import android.graphics.PorterDuff; import android.os.Bundle; import android.provider.Settings; import android.view.View; import android.view.View.OnClickListener; import android.widget.EditText; import android.view.Menu; import android.view.MenuInflater; import android.view.MenuItem; public class Activitate extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); View btn_ok = findViewById(R.id.btn_ok); btn_ok.setOnClickListener(new OnClickListener() { public void onClick(View v) { CalculeazaSuma(); } }); } private void CalculeazaSuma() { AplicatieSuma appState = ((AplicatieSuma)this.getApplication()); EditText txt_amount = (EditText)findViewById(R.id.txt_amount); txt_amount.setText(appState.service.CalculateSum()); //BindData(); } } So that edit text does not show the sum of the random generated numbers, by the service. What's wrong? Thanks EDIT: the manifest xml file: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.android" android:versionCode="1" android:versionName="1.0.1"> <supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:anyDensity="true" /> <application android:name="ApplicationSum" android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true"> <activity android:label="@string/app_name" android:name=".Activitate"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="7" android:targetSdkVersion="7" /> </manifest>

    I am trying to learn fragments to modernize an app I originally wrote for android 1.5 that uses Date Picker Dialog. I am using the android-support-v4 library. When I run the code in Eclipse Juno 20120614-1722 it only shows android 4.0 emulators and there is a red X beside my Samsung phone running 2.3.5. When I push the package to phone, the code runs.

  • Android Augmented Reality

    - by Azooz Totti
    I'm working on my first Android Augmented Reality application. The application works pretty good if the ARActivity runs as the first class (android.intent.category.LAUNCHER) in the manifest file. But when I added a splash screen which means the ARActivity will be the second to run(android.intent.category.DEFAULT), the camera seems not detecting the marker. I believe the problem is all in the manifest file. Any suggestions ?

  • 2D Collision in Canvas - Balls Overlapping When Velocity is High

    - by kushsolitary
    I am doing a simple experiment in canvas using Javascript in which some balls will be thrown on the screen with some initial velocity and then they will bounce on colliding with each other or with the walls. I managed to do the collision with walls perfectly but now the problem is with the collision with other balls. I am using the following code for it: //Check collision between two bodies function collides(b1, b2) { //Find the distance between their mid-points var dx = b1.x - b2.x, dy = b1.y - b2.y, dist = Math.round(Math.sqrt(dx*dx + dy*dy)); //Check if it is a collision if(dist <= (b1.r + b2.r)) { //Calculate the angles var angle = Math.atan2(dy, dx), sin = Math.sin(angle), cos = Math.cos(angle); //Calculate the old velocity components var v1x = b1.vx * cos, v2x = b2.vx * cos, v1y = b1.vy * sin, v2y = b2.vy * sin; //Calculate the new velocity components var vel1x = ((b1.m - b2.m) / (b1.m + b2.m)) * v1x + (2 * b2.m / (b1.m + b2.m)) * v2x, vel2x = (2 * b1.m / (b1.m + b2.m)) * v1x + ((b2.m - b1.m) / (b2.m + b1.m)) * v2x, vel1y = v1y, vel2y = v2y; //Set the new velocities b1.vx = vel1x; b2.vx = vel2x; b1.vy = vel1y; b2.vy = vel2y; } } You can see the experiment here. The problem is, some balls overlap each other and stick together while some of them rebound perfectly. I don't know what is causing this issue. Here's my balls object if that matters: function Ball() { //Random Positions this.x = 50 + Math.random() * W; this.y = 50 + Math.random() * H; //Random radii this.r = 15 + Math.random() * 30; this.m = this.r; //Random velocity components this.vx = 1 + Math.random() * 4; this.vy = 1 + Math.random() * 4; //Random shade of grey color this.c = Math.round(Math.random() * 200); this.draw = function() { ctx.beginPath(); ctx.fillStyle = "rgb(" + this.c + ", " + this.c + ", " + this.c + ")"; ctx.arc(this.x, this.y, this.r, 0, Math.PI*2, false); ctx.fill(); ctx.closePath(); } }

  • How to add a Fragment inside a ViewPager using Nested Fragment (Android 4.2)

    - by sabadow
    I have a ViewPager with three Fragments, each one shows a List (or Grid). In the new Android API level 17 (Jelly Bean 4.2), one of the features is Nested Fragments. The new functionality description says: if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page. So, if I understand right, now I can create a ViewPager with Fragments (with a button inside for example) inside, and when user press the button show another Fragment without loose the ViewPager using this new feature. I expend my morning trying to implement this on several ways but I can´t made it... Can somebody show a simple example of how to do this? PS: I'm only interested in doing at this way, with getChildFragmentManager to learn how works.

  • Android Emulator - Cannot get keyboard to display

    - by Ash
    Basically I cannot get the onscreen keyboard to display at all. I've tried every solution I've read to make it appear within my application, and now I've come to the conclusion that it must be the emulator as it isn't appearing when using Messages, writing e-mails etc. I've looked in Language & input within settings and checked Sample Soft Keyboard, rebooted the emulator with no change. Using Android SKD 2.3.3 3.7in WVGA (Nexus One) I'm hoping someone can maybe guess what's going on. Many thanks

  • Bottom button bar overlaps the last element of Listview!!

    - by elto
    I have a listview which is part of an Activity. I want user to have a choice for batch deleting the items in the listview, so when he chooses the corresponding option from the menu, every list item gets a checkbox next to it. When user clicks any checkbox, a button bar is to slide up from bottom (as in gmail app) and clicking delete button deletes the selected items, however clicking cancel button on the bar would uncheck all the checked items. This is my page layout.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@android:color/transparent" > <FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent" > <LinearLayout android:id="@+id/list_area" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > <ListView android:id="@+id/mylist" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@android:color/transparent" android:drawSelectorOnTop="false" android:layout_weight="1" /> <TextView android:id="@+id/empty_list_message" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#FFFFFF" android:layout_gravity="center_vertical|center_horizontal" android:text="@string/msg_for_emptyschd" android:layout_margin="14dip" android:layout_weight="1" /> </LinearLayout> <RelativeLayout android:id="@+id/bottom_action_bar" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/schedule_bottom_actionbar_border" android:layout_marginBottom="2dip" android:layout_gravity="bottom" android:visibility="gone" > <Button android:id="@+id/delete_selecteditems_button" android:text="Deleted Selected" android:layout_width="140dip" android:layout_height="40dip" android:layout_alignParentLeft="true" android:layout_marginLeft="3dip" android:layout_marginTop="3dip" /> <Button android:id="@+id/cancel_button" android:text="Cancel" android:layout_width="140dip" android:layout_height="40dip" android:layout_alignParentRight="true" android:layout_marginRight="3dip" android:layout_marginTop="3dip" /> </RelativeLayout> </FrameLayout> </LinearLayout> so far, I have got everything working except that when the bottom bar becomes visible upon checkbox selection, it overlaps the last element of the list. All other list items can be scrolled up, but you cant scroll up the very last item of the list, therefore user can not select that item if he intends to. Here is the screenshot of the overlap. I have tried using the listview footer option, but that appends the bar to the end of the list instead of keeping it fixed at the bottom of the screen. Is there a way I could "raise" the listview enough so that the overlap wont happen?? BTW, I have already tried adding the bottom-margin to the listview itself, or the LinearLayout wrapping the listview right before making the button-bar visible, but it introduces other bugs like clicking one checkbox checks some another checkbox in listview.

  • How to build Open JavaFX for Android.

    - by PictureCo
    Here's a short recipe for baking JavaFX for Android dalvik. We will need just a few ingredients but each one requires special care. So let's get down to the business.  SourcesThe first ingredient is an open JavaFX repository. This should be piece of cake. As always there's a catch. You probably know that dalvik is jdk6 compatible  and also that certain APIs are missing comparing to good old java vm from Oracle.  Fortunately there is a repository which is a backport of regular OpenJFX to jdk7 and going from jdk7 to jdk6 is possible. The first thing to do is to clone or download the repository from https://bitbucket.org/narya/jfx78. Main page of the project says "It works in some cases" so we will presume that it will work in most cases As I've said dalvik vm misses some APIs which would lead to a build failures. To get them use another compatibility repository which is available on GitHub https://github.com/robovm/robovm-jfx78-compat. Download the zip and unzip sources into jfx78/modules/base.We need also a javafx binary stubs. Use jfxrt.jar from jdk8.The last thing to download are freetype sources from http://freetype.org. These will be necessary for native font rendering. Toolchain setup I have to point out that these instructions were tested only on linux. I suppose they will work with minimal changes also on Mac OS. I also presume that you were able to build open JavaFX. That means all tools like ant, gradle, gcc and jdk8 have been installed and are working all right. In addition to this you will need to download and install jdk7, Android SDK and Android NDK for native code compilation.  Installing all of them will take some time. Don't forget to put them in your path. export ANDROID_SDK=/opt/android-sdk-linux export ANDROID_NDK=/opt/android-ndk-r9b export JAVA_HOME=/opt/jdk1.7.0 export PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK FreetypeUnzip freetype release sources first. We will have to cross compile them for arm. Firstly we will create a standalone toolchain for cross compiling installed in ~/work/ndk-standalone-19. $ANDROID_NDK/build/tools/make-standalone-toolchain.sh  --platform=android-19 --install-dir=~/work/ndk-standalone-19 After the standalone toolchain has been created cross compile freetype with following script: export TOOLCHAIN=~/work/freetype/ndk-standalone-19 export PATH=$TOOLCHAIN/bin:$PATH export FREETYPE=`pwd` ./configure --host=arm-linux-androideabi --prefix=$FREETYPE/install --without-png --without-zlib --enable-shared sed -i 's/\-version\-info \$(version_info)/-avoid-version/' builds/unix/unix-cc.mk make make install It will compile and install freetype library into $FREETYPE/install. We will link to this install dir later on. It would be possible also to link openjfx font support dynamically against skia library available on Android which already contains freetype. It creates smaller result but can have compatibility problems. Patching Download patches javafx-android-compat.patch + android-tools.patch and patch jfx78 repository. I recommend to have look at patches. First one android-compat.patch updates openjfx build script, removes dependency on SharedSecret classes and updates LensLogger to remove dependency on jdk specific PlatformLogger. Second one android-tools.patch creates helper script in android-tools. The script helps to setup javaFX Android projects. Building Now is time to try the build. Run following script: JAVA_HOME=/opt/jdk1.7.0 JDK_HOME=/opt/jdk1.7.0 ANDROID_SDK=/opt/android-sdk-linux ANDROID_NDK=/opt/android-ndk-r9b PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK:$PATH gradle -PDEBUG -PDALVIK_VM=true -PBINARY_STUB=~/work/binary_stub/linux/rt/lib/ext/jfxrt.jar \ -PFREETYPE_DIR=~/work/freetype/install -PCOMPILE_TARGETS=android If everything went all right the output is in build/android-sdk Create first JavaFX Android project Use gradle script int android-tools. The script sets the project structure for you.   Following command creates Android HelloWorld project which links to a freshly built javafx runtime and to a HelloWorld application. NAME is a name of Android project. DIR where to create our first project. PACKAGE is package name required by Android. It has nothing to do with a packaging of javafx application. JFX_SDK points to our recently built runtime. JFX_APP points to dist directory of javafx application. (where all application jars sit) JFX_MAIN is fully qualified name of a main class. gradle -PDEBUG -PDIR=/home/user/work -PNAME=HelloWorld -PPACKAGE=com.helloworld \ -PJFX_SDK=/home/user/work/jfx78/build/android-sdk -PJFX_APP=/home/user/NetBeansProjects/HelloWorld/dist \ -PJFX_MAIN=com.helloworld.HelloWorld createProject Now cd to the created project and use it like any other android project. ant clean, debug, uninstall, installd will work. I haven't tried it from any IDE Eclipse nor Netbeans. Special thanks to Stefan Fuchs and Daniel Zwolenski for the repositories used in this blog post.

  • Installing Lubuntu on to Android tablet and switching os in between

    - by user1702061
    I would like to install Lubuntu onto my tablet, as it seems more lightweight than ubuntu. However, it seems there are only images for Windows/ Mac? For Android devices, what image shall I download? I've also found an article about installing Ubuntu on Android phone. And by installing VNC, it seems that one could "switch" from OS to OS on the phone, i.e. I could be viewing the Ubuntu OS on the phone via a VNC viewer, and closing the viewer gives me back the Android OS. My questions are: 1) What ubuntu/lubuntu image (windows?mac?) shall I download in order to get this done? 2) My ultimate goal is to run some windows programs on a Android tablet. I am planning install a lubuntu os and then wine... what will be the minimum hardware requirement in order to do this? Thank you very much!

  • Android - passing data between Activities

    - by Bill Osuch
    (To follow along with this, you should understand the basics of starting new activities: Link ) The easiest way to pass data from one activity to another is to create your own custom bundle and pass it to your new class. First, create two new activities called Search and SearchResults (make sure you add the second one you create to the AndroidManifest.xml file!), and create xml layout files for each. Search's file should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="Name:"/>     <EditText                android:id="@+id/edittext"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="ID Number:"/>     <EditText                android:id="@+id/edittext2"                android:layout_width="fill_parent"                android:layout_height="wrap_content"/>     <Button           android:id="@+id/btnSearch"          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="Search" /> </LinearLayout> and SearchResult's should look like this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <TextView          android:id="@+id/txtName"         android:layout_width="fill_parent"         android:layout_height="wrap_content"/>     <TextView          android:id="@+id/txtState"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:text="No data"/> </LinearLayout> Next, we'll override the OnCreate method of Search: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search);     Button search = (Button) findViewById(R.id.btnSearch);     search.setOnClickListener(new View.OnClickListener() {         public void onClick(View view) {                           Intent intent = new Intent(Search.this, SearchResults.class);              Bundle b = new Bundle();                           EditText txt1 = (EditText) findViewById(R.id.edittext);             EditText txt2 = (EditText) findViewById(R.id.edittext2);                                      b.putString("name", txt1.getText().toString());             b.putInt("state", Integer.parseInt(txt2.getText().toString()));                              //Add the set of extended data to the intent and start it             intent.putExtras(b);             startActivity(intent);          }     }); } This is very similar to the previous example, except here we're creating our own bundle, adding some key/value pairs to it, and adding it to the intent. Now, to retrieve the data, we just need to grab the Bundle that was passed to the new Activity and extract our values from it: @Override public void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.search_results);     Bundle b = getIntent().getExtras();     int value = b.getInt("state", 0);     String name = b.getString("name");             TextView vw1 = (TextView) findViewById(R.id.txtName);     TextView vw2 = (TextView) findViewById(R.id.txtState);             vw1.setText("Name: " + name);     vw2.setText("State: " + String.valueOf(value)); }
