Controlling the frame animation speed with seek bar in android - android

I have the following code that changes the opacity of the frame animation with the help of a seekbar, now i'm trying to control the duration of frame animation with the help of this seek bar, can anybody help me in telling that if it is possible?
The code:
ImageView myAnimation = (ImageView)findViewById(R.id.myanimation);
//Create a new AnimationDrawable
final AnimationDrawable myAnimationDrawable
= createAnimationDrawable();
//apply the new AnimationDrawable
myAnimation.setImageDrawable(myAnimationDrawable);
SeekBar setAnimationAlpha = (SeekBar)findViewById(R.id.setalpha);
Button startAnimation = (Button)findViewById(R.id.startanimation);
Button stopAnimation = (Button)findViewById(R.id.stopanimation);
startAnimation.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(!myAnimationDrawable.isRunning()){
myAnimationDrawable.start();
}
}});
stopAnimation.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if(myAnimationDrawable.isRunning()){
myAnimationDrawable.stop();
}
}});
setAnimationAlpha.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener(){
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
myAnimationDrawable.setAlpha(progress);
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}});
}
private AnimationDrawable createAnimationDrawable(){
AnimationDrawable newAnim = new AnimationDrawable();
newAnim.addFrame(getResources().getDrawable(R.drawable.android_1), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_2), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_3), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_4), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_5), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_6), 90);
newAnim.addFrame(getResources().getDrawable(R.drawable.android_7), 90);
newAnim.setOneShot(false);
return newAnim;
}
}

how to animate the seekbar so that it one drags the thumb to seekbar max value the thumb automatically goes back to initial point.I am a begginer so plz if possible give a elaborated answer
sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
#Override
public void onProgressChanged(SeekBar seekBar,
int progress, boolean fromUser) {
value = sb.getProgress();
if (value == 50) {
Drawable drawable = getResources().getDrawable(
R.drawable.off);
sb.setThumb(drawable);
}
ValueAnimator anim = ValueAnimator.ofInt(seekBar.getProgress(),0);
anim.setDuration(1000);
anim.addUpdateListener(new AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
int animProgress = (Integer) animation.getAnimatedValue();
sb.setProgress(animProgress);
}
});
anim.start();
}
});
I have got the answer to my question. If anyone one need it, then it is....
SeekBar sb;
ValueAnimator anim;
int value;
sb.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar,
int progress, boolean fromUser) {
}
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
value = sb.getProgress();
ValueAnimator anim = ValueAnimator.ofInt(value,
sb.getMax());
anim.setDuration(1000);
anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(
ValueAnimator animation) {
value = (Integer) animation
.getAnimatedValue();
sb.setProgress(value);
}
});
anim.start();
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
ValueAnimator anim = ValueAnimator.ofInt(0,
sb.getMax());
anim.setDuration(1000);
anim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

ValueAnimator animation) {
value = (Integer) animation
.getAnimatedValue();
value = 100 - value;

How to resize image by using seekbar?

I want to resize image by using seekbar. Seekbar is working but its not giving any good results. With the following code, the image is resized but just when you change the progress of seekbar for the first time. Please help
Seekbar listener
seekBar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
#Override
public void onStartTrackingTouch(SeekBar arg0) {
// TODO Auto-generated method stub
}
#Override
public void onProgressChanged(SeekBar seekBar, int progresValue,
boolean fromUser) {
// TODO Auto-generated method stub
progresValue = progress;
resizeImage(image, progresValue);
}
});
Function to resize image
public void resizeImage(Bitmap bitmap, int progress) {
Bitmap bitmapSource = bitmap;
float bHeight = bitmapSource.getHeight();
float bWidth = bitmapSource.getWidth();
float factorH = progress / (float) bHeight;
float factorW = progress / (float) bWidth;
float factorToUse = (factorH > factorW) ? factorW : factorH;
Bitmap bm = Bitmap.createScaledBitmap(bitmapSource,
(int)(bWidth * factorToUse), (int)(bHeight * factorToUse),
false);
qImage.setImageBitmap(bm);
}
final SeekBar sk1 = (SeekBar) findViewById(R.id.seekBar1);
sk1.setMax(500);
sk1.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
public void onStopTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onStartTrackingTouch(SeekBar seekBar) {
// TODO Auto-generated method stub
}
public void onProgressChanged(SeekBar seekBar, int progress,boolean fromUser) {
// TODO Auto-generated method stub
img.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(progress,progress);
img.setLayoutParams(params);
img.setMinimumWidth(progress);
img.setMinimumHeight(progress);
}
});

Android animation when scroll

I want do a animate scroll like Jquery´s (in this web page works when you click in top menu´s options) in android. is it possible? I have seen that exists scrollTo but is possible to do with animation and not like jumps. Thank you very much.
Using ObjectAnimator, This is a sample for scrolling to top :
public void scroolToTop() {
int x = 0;
int y = 0;
ObjectAnimator xTranslate = ObjectAnimator.ofInt(mScrollView, "scrollX", x);
ObjectAnimator yTranslate = ObjectAnimator.ofInt(mScrollView, "scrollY", y);
AnimatorSet animators = new AnimatorSet();
animators.setDuration(1000L);
animators.playTogether(xTranslate, yTranslate);
animators.addListener(new AnimatorListener() {
#Override
public void onAnimationStart(Animator arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animator arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animator arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationCancel(Animator arg0) {
// TODO Auto-generated method stub
}
});
animators.start();
}

Killing a Sprite in AndEngine

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;
}

ViewHelper in NinaOldAndroid does not work outside of onCreate() method

I try to set ViewHelper.setPivotY(test, 0); in method onClick() but it doesn't work. The animation still scale to the centerY. Here is my code. I don't know where I am wrong?
public class NewClassTest extends Activity{
LinearLayout test;
FrameLayout content;
Button btn;
boolean toggle = true;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.test_activity);
test = (LinearLayout) findViewById(R.id.test);
content = (FrameLayout) findViewById(R.id.content);
content.setVisibility(View.INVISIBLE);
btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// ViewHelper.setPivotY(test, 0); does not work
runAnimation(toggle);
toggle = !toggle;
}
});
ViewHelper.setPivotY(test, 0); // work
}
private void runAnimation(boolean in){
AnimatorSet animSet = new AnimatorSet();
ObjectAnimator anim = null, anim2 = null;
// ViewHelper.setPivotY(test, 0); also does not work
if(in){
anim = ObjectAnimator.ofFloat(test, "scaleY", 1, 1 - (((float)content.getHeight()) / ((float) test.getHeight())));
anim2 = ObjectAnimator.ofFloat(content, "translationY", content.getHeight(), 0);
animSet.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
// TODO Auto-generated method stub
content.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationRepeat(Animator animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animator animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationCancel(Animator animation) {
// TODO Auto-generated method stub
}
});
}else {
anim = ObjectAnimator.ofFloat(test, "scaleY", 1 - ((float)content.getHeight()) / ((float) test.getHeight()), 1);
anim2 = ObjectAnimator.ofFloat(content, "translationY", 0, content.getHeight());
animSet.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animator animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animator animation) {
// TODO Auto-generated method stub
content.setVisibility(View.INVISIBLE);
}
#Override
public void onAnimationCancel(Animator animation) {
// TODO Auto-generated method stub
}
});
}
animSet.setDuration(1000).play(anim2).with(anim);
animSet.start();
}
Thank for your help!.
Happen to me also. test it on HTC One S with android 4.1 and that wasn't worked, but in Samsung Galaxy I with android 2.2 it worked as expected.
Changed it to ViewHelper.setPivotY(test, 0.00000001f); solved it =\
Don't know if it's a bug of HTC, android or nineoldandroids
