i developed a map who can rotate the direction view depend where the user face (example, if the user turn into south,than map will rotating to south direction, like compass). I already tried this project with minimal success for a couple week. I have no error message on eclipse,but when i debug the code, the application always crash.
Thanks,i really need all the help

Solved this, just change i<=count into i<count, and everything will work! But my zoom and compass didn't show.

I want to implement interactive TabPageIndicatot in android. I am using ViewPager.TabPageIndicator to make object of indicator.I am trying to implement scrollTo in TabPageIndicator class.
This is the code in my class. indicator is object of TabPageIndicator.
public void onPageScrolled(int pageNo, float arg1, final int arg2) {
// TODO Auto-generated method stub
indicator.scrollTo(arg2, 0);
}
This is the code in TabPageIndicator class.
private void animateToTab(final int x) {
if (mTabSelector != null) {
removeCallbacks(mTabSelector);
}
mTabSelector = new Runnable() {
public void run() {
// final int scrollPos = tabView.getLeft() - (getWidth() - tabView.getWidth()) / 2;
smoothScrollTo(x, 0);
mTabSelector = null;
}
};
post(mTabSelector);
}
#Override
public void scrollTo(int x, int y) {
// TODO Auto-generated method stub
super.scrollTo(x, y);
//Log.i("Hi", Integer.toString(x));
animateToTab(x);
}
Here animateToTab() function is called infinite times. Why?
I am using touch listener for an imageview in the listview item .It is working fine when I just do that like an sample application(I mean I have that Listview item as an sample one). But when I put this in a listview it is really becoming very slow.
I just wants to drag the image only horizantally,for that purpose I used ConstrainedDragandDrop View class which I got from the Github.
In my sample application:
public class HorizontalScroll extends Activity {
ImageView full_left,heart;
RelativeLayout rlMainLayout,rlImages,Cartoon_image,half_left,play_btn,centre,centre_leftanimate;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.inflated_bloops);
half_left=(RelativeLayout)findViewById(R.id.half_left);
Cartoon_image=(RelativeLayout)findViewById(R.id.cartoon_image);
play_btn=(RelativeLayout)findViewById(R.id.play_btn);
heart=(ImageView)findViewById(R.id.ivheart);
ConstrainedDragAndDropView dndView = (ConstrainedDragAndDropView) findViewById(R.id.dndView);
dndView.setDragHandle(findViewById(R.id.cartoon_image),findViewById(R.id.half_left),heart);
dndView.setAllowVerticalDrag(false,HorizontalScroll.this);
}
}
When I used in my Listview:
public class Cars extends BaseAdapter
{
public View getView(int position, View convertView, ViewGroup parent)
{
View v = convertView;
LayoutInflater inflator = getLayoutInflater();
v= inflator.inflate(R.layout.inflated_bloops, null);
ConstrainedDragAndDropView dndView = (ConstrainedDragAndDropView) v.findViewById(R.id.dndView);
dndView.setDragHandle(v.findViewById(R.id.cartoon_image),v.findViewById(R.id.half_left),heart);
dndView.setAllowVerticalDrag(false,FeedModeActivity.this);
RelativeLayout Cartoon_image=(RelativeLayout)v.findViewById(R.id.cartoon_image);
ImageView ivDummy =(ImageView)v.findViewById(R.id.dummy);
try{
loader.DisplayImageRelative( al_new.get(position).replace(" ", "%20"),ivDummy, Cartoon_image);
}
catch(Exception e){
e.printStackTrace();
}
return v;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return al_new.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub

Currently I am working on live wallpaper and I am stuck at a point. Actually, my live wallpaper only works when I touch the screen, but it doesn't change continuously. There is a problem in my loop.

i++;
if (i == 13) {

}
}
After adding this
if (mVisible) {
Handler.postDelayed(diwaliImg,80);
}
At the end draw frame() my problem was solved.
There is no loop in your code. You need to call drawFrame() repeatedly.
To achieve this you may use separate thread for animation. I recommend you my wallpaper template available on GitHub.
Hi im having a bit of problems getting my sprite to fade back in. Im using paralell entity modifiers, scaling and fading after which the sprite gets new X and Y cordinates and fades in and scales back up. It doesnt work and i think it might have something to do with the onUpdate method.
XOsprite = new Sprite(x, y, XO, engine.getVertexBufferObjectManager()) {
#Override
public boolean onAreaTouched(final TouchEvent te, final float xVal,
final float yVal) {
XOsprite.registerEntityModifier(downOut); //kill sprite
isKilled = true;
XOsprite.registerUpdateHandler(new IUpdateHandler() {
#Override
public void reset() {
// TODO Auto-generated method stub
}
#Override
public void onUpdate(float pSecondsElapsed) {
// TODO Auto-generated method stub
totalElapsedTime += pSecondsElapsed;
if(totalElapsedTime >= 3.0f){
BaseGameActivity gameActivity = (BaseGameActivity) activity;
gameActivity.runOnUpdateThread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
if(isKilled){
reviveSprite();
isKilled = false;
}
}
});
}
//reset();
}
});
return true;
}
};
XOsprite.registerEntityModifier(inUp);
gameScene.attachChild(XOsprite);
gameScene.registerTouchArea(XOsprite);
return gameScene;
}
-edit- more code
public void reviveSprite(){
setSprites();
XOsprite.unregisterEntityModifier(downOut);
XOsprite.registerEntityModifier(inUp);
}
public void setSprites(){
if (rand.nextInt(2) == 0) {
XO = X;
} else {
XO = O;
}
x = rand.nextInt(MainActivity.CAM_WIDTH);
y = rand.nextInt(MainActivity.CAM_HEIGHT);
}
you are already on the UpdateThread, so no need to do this
gameActivity.runOnUpdateThread(new Runnable() {
#Override
public void run() {
// TODO Auto-generated method stub
if(isKilled){
reviveSprite();
isKilled = false;
}
}
});
just do this
if(isKilled){
reviveSprite();
isKilled = false;
}

Change your animationstop_01 method to:
void animationstop_01(){
if(law=="firstlaw_02"){
timer=new Thread(){
#Override
public void run(){
try{
Thread.sleep(8750);
}catch(Exception e){
}finally{
Log.w("debug","it is firstlaw_02");
Newton_LawsActivity.this.runOnUiThread(new Runnable() {
public void run(){
animation.setBackgroundResource(R.anim.firstlaw_02);
final AnimationDrawable firstlaw_02 = (AnimationDrawable) animation.getBackground();
law="firstlaw_03";
AnimationStart(firstlaw_02);
}
});
}
};
};
timer.start();
}
}
Error is inside the mehod name animationstop_01() where you are trying,
animation.setBackgroundResource(R.anim.firstlaw_02);
put that inside runOnUiThread()
try this:
animation.post(new Runnable() {
public void run() {
animation.setBackgroundResource(R.anim.firstlaw_02);
}
});
In that way you are posting it to the UI thread. View can only be changed from the original thread that created the View.
