30Have you considered using Frame Animations?

You can specify an xml in your anim folder that contains a frame-by-frame animation, specifing each image duration, and other settings, check

it out

UPDATE

You can also build a frame animation programmatically of course:

AnimationDrawable animation = new AnimationDrawable();animation.addFrame(getResources().getDrawable(R.drawable.image1), 100);animation.addFrame(getResources().getDrawable(R.drawable.image2), 500);animation.addFrame(getResources().getDrawable(R.drawable.image3), 300);animation.setOneShot(false);

ImageView imageAnim = (ImageView) findViewById(R.id.img);imageAnim.setBackgroundDrawable(animation);

// start the animation!animation.start()

thanks, that worked really well, im an android novice and im programming something for a tablet using 3.1 when i run the app on my virtual android device it brings up a much smaller screenin like portrait is there anyway to fix this and is there any easy way to make an image view fill the screen? Thankyou so much Marty Cochrane May 25 '11 at 16:53

try putting this on the ImageView xml properties: android:layout_width="fill_parent" android:layout_height="fill_parent". And then set also the android:scaleType property with the value youneed. Look at this link: android-developers.blogspot.com/2009/03/ BFilMay 25 '11 at 17:01

Works good @BFil. Thanks!!! groff07Oct 24 '13 at 12:50

6you can use the CountDownTimer: follow these steps :

1) declare an arraywhich will contain the identifients of your pictures

2 ) declare the CountDownTimerlike this :

int i=0;new CountDownTimer(10000,1000) {

@Overridepublic void onTick(long millisUntilFinished) {}

@Overridepublic void onFinish() {

imgView.setImageDrawable(sdk.getContext().getResources().getDrawable(array[i]));i++;if(i== array.length-1) i=0;start();

}}.start();

This worked. Thank you so much. Dog LoverMay 20 '15 at 7:40

2Create a Runnablethat executes the change you want (I suppose it will be changing an ImageView's bitmap/drawable), and post them with delayto the main thread loop, using a Handlerand its postDelayed()method.

To make it a loop, you could have the runnable post itself.

1create blink.xml

put blink.xml in drawable folder and in activity Code write this.

ImageView mImageView ;mImageView = ( ImageView)findViewById(R.id.imageView); //this is your imageViewmImageView .setImageDrawable(getResources().getDrawable( R.drawable.blink));

then you will get what you want.!

This one is cleaner Jason ChuehAug 10 '15 at 1:00
