i am making a flashlight app in which i am using using two images, one each for flashoff state and flashon state respectively.
i want to have animation such that these two images get toggled(image 1 apperas then image2 then again image 2..infinite times) when there is longclick..
that is iwant to show this in longclicklistner...
here is what i have done..
i am using this animation..
<?xml version="1.0" encoding="utf-8"?>
<set
xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:duration="1000" android:repeatCount="infinite" android:repeatMode="reverse" android:fromAlpha="0.3" android:toAlpha="1.0" />
and
#Override
public boolean onLongClick(View arg0) {
// TODO Auto-generated method stub
tButton.startAnimation(flickon); //tbutton is an image button
return true;
}
});
}
using this animation is happening but images are not switching..please help
ImageView image = (ImageView) findViewById(R.id.test_image);
image.setImageResource(R.drawable.xxx);
use the above code to set an image to the image view and use a thread that can change contents in the UI bascially some thing like this
public void onLongClick(View v) {
new Thread(new Runnable() {
public void run() {
ImageView image = (ImageView) findViewById(R.id.test_image);
image.setImageResource(R.drawable.xxx);
}
}).start();
}
You can loop over it for as many times as you want.

I have two images which I want to fade between causing a glowing on and off effect. This should run all the time like an animation, not just when the button is pressed.
Here are the two images:
This was working well before but after some hardware/android OS updates my animation is really jumpy. Here is the Animation XML I was using:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/bottom_bar_add_dark"/>
<item android:drawable="#drawable/bottom_bar_add" android:duration="500" />
</animation-list>
I have looked high and low and cannot find an answer to this.
Edit
Here is the code that creates the image view and sets all its resources:
public ImageView findDevicesButton(){
bottomButton = new ImageView(this);
int id = bottomButton.generateViewId();
bottomButton.setId(id);
if(currentapiVersion >= 11){
bottomButton.setImageResource(R.drawable.animationxmladddevice);
//Background image
bottomButton.setBackgroundResource(R.drawable.bottom_bar);
saveButtonAnimation = (AnimationDrawable)bottomButton.getDrawable();
saveButtonAnimation.setEnterFadeDuration(1000);
saveButtonAnimation.setExitFadeDuration(1000);
bottomButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
findDevicesAlertBuilder();
}
});
}else{
bottomButton.setImageResource(R.drawable.bottom_bar_add);
bottomButton.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
bottomButton.setBackgroundResource(R.drawable.bottom_bar);
bottomButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
findDevicesAlertBuilder();
}
});
}
return bottomButton;
}
This is the back background image:
All together it should look like this with the center button glowing:
I am working on android. I want to create a rotating image and select parts on it. For example if the image is a human head then while its rotating, the ears can be selected. Now I did the image part selection, but I don't know how to rotate it? Can somebody show me an easy way?
You have 2 ways to rotate a image, i put the simple with xml.
First inside directory res create a directory with the name anim
inside the directory anim create a file xml with this code:
<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1000"
>
</rotate>
this code is the instruction to make a image rotate.
finally your main activity must look like that:
public class MainActivity extends Activity implements OnClickListener{
ImageView imagen; //declare the image will use
Button boton; // this button will activie de rotation
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imagen = (ImageView) findViewById(R.id.iv);
boton = (Button)findViewById(R.id.bt);
boton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bt:
Animation rotacion; // declare an animation
rotacion = AnimationUtils.loadAnimation(this,R.anim.rotar);
rotacion.reset();
imagen.startAnimation(rotacion);
break;
default:
break;
}
}
You should use http://developer.android.com/reference/android/view/animation/RotateAnimation.html class to make animation and animate your view
In my android application I have four imageviews when I click any one of that all(4) images are animating. I set the zoomout animation for all the images. once the animation is finished I am starting a new activity. The problem is once i click a back button The images(all the 4) images are hide. If I start a application from home screen the Images are showing. please anyone help me how to show the images once i click the back button
synopsis.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
//synopsis.setBackgroundResource(R.drawable.aa);
synopsis.startAnimation(animZoomOut);
team.startAnimation(animZoomOut);
music.startAnimation(animZoomOut);
gallery.startAnimation(animZoomOut);
//synopsis.startAnimation(android.R.anim.slide_in_left);
animZoomOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
intent = new Intent(HomeActivity.this, Activity_Synopisis.class);
startActivity(intent);
}
});
}
});

The activity is being recreated thus the animation result is gone, you either need to have some sort of preference or pass a variable in the bundle, when the activity after the animation loads, set the variable 'animation_finished' to true and then simply check in the oncreate of the imageview activity: if true: show/hide your images appropriately
When the new activity is started, the old activity with the 4 images will remain in the state (i.e. with all images zoomed-out), so when you resume the old activity, you won't see that. One solution is to set the state of the 4 images to "normal" (i.e. show them) in the onResume() method of your old activity.
As per your short note and my understanding,
intent = new Intent(HomeActivity.this, Activity_Synopisis.class);
startActivity(intent);
synopsis.cancel();
team.cancel();
music.cancel();
gallery.cancel();
Try this one,It may help you out...
Thanks for the answer all.
I resolved this with the follo
synopsis.clearAnimation();
team.clearAnimation();
gallery.clearAnimation();
music.clearAnimation();
Added these above lines of code in Resume
i am enable to load animation in Emulater..Its working fine with any real device..
public class MainActivity extends Activity {
private ImageView imgView;
private Animation animation;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.grow);
animation.setRepeatCount(50); // Repeat animation infinitely
animation.setRepeatMode(Animation.REVERSE);
imgView = (ImageView) findViewById(R.id.imgView);
imgView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
imgView.startAnimation(animation);
new Handler().postDelayed(new Runnable() {
public void run() {
Intent it = new Intent(getApplicationContext(), MyWebView.class);
startActivity(it);
}
}, 5000);
}
});
}
and my anim xml file is following
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="50" />
I think you Might have Disabled Animations in Emulator:
Check that:
Settings>Display>Animation..
Hope that helps your Problem
For anyone running into similar issues when using ObjectAnimator, in my case I had to enable the developer settings on the emulator and then go into "Settings" > "Developer options" > "Drawing" section
In this "Drawing" section you'll find different options for each animation type, in my case the "Animator duration scale" was off, after setting it to "1x" I started seeing the animations on the emulator.
How can I spin a image wheel in an activity on android with the help of touch event? I need some guideline or link of any tutorial.
This is typically done with a couple pieces. This is how I do it in one of my apps. *Note: This is not a smooth wheel, so much as it starts and stops at the top (which was intentional). You can lookup more about Animation on the dev site.
Main XML that has an image:
<ImageView
android:id="#+id/anim_example"
android:src="#drawable/loading_circle"
android:layout_width="30sp"
android:layout_height="30sp"
android:onClick="RunAnimation" />
Here are the parts in code that run the animation
public void RunAnimation(View v)
{
//The onClick method has to be present and must take the above parameter.
StartLoading();
//This will delay the stop for 5 seconds
//Normally you would want to actually have this run based on some other input/data.
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
StopLoading();
}
}, 5000);
}
public void StartLoading() {
ImageView refreshImage = (ImageView) this.findViewById(R.id.anim_example);
refreshImage.setImageDrawable(getResources().getDrawable(R.drawable.loading_circle));
Animation rotateLoading = AnimationUtils.loadAnimation(this, R.anim.rotate);
refreshImage.clearAnimation();
refreshImage.setAnimation(rotateLoading);
}
public void StopLoading() {
ImageView refreshImage = (ImageView) this.findViewById(R.id.anim_example);
if (refreshImage.getAnimation() != null)
{
refreshImage.clearAnimation();
refreshImage.setImageDrawable(getResources().getDrawable(R.drawable.loading_circle));
}
}
anim.rotate:
<?xml version="1.0" encoding="utf-8"?>
<rotate

android:fromDegrees="0"
android:toDegrees="359"
