Hi All,
The frame animation works fine according to this thread, thanks.
My question is: how to set the duration of the frame by code (not by
XML). The following is my code to implement the frame animation by
code:
--
button2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
img = (ImageView)
findViewById(R.id.spinning_wheel_image);
frameAnimation = new AnimationDrawable();
DrawableContainerState containerState =
(DrawableContainerState)
frameAnimation.getConstantState();
long duration = 10000L;
long now = SystemClock.uptimeMillis();
long i = 0L;
Drawable d =
getResources().getDrawable(R.drawable.wheel0);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
d =
getResources().getDrawable(R.drawable.wheel1);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
d =
getResources().getDrawable(R.drawable.wheel2);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
d =
getResources().getDrawable(R.drawable.wheel3);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
d =
getResources().getDrawable(R.drawable.wheel4);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
d =
getResources().getDrawable(R.drawable.wheel5);
containerState.addChild(d);
frameAnimation.scheduleDrawable(d,
frameAnimation, now
+i*duration);
i++;
img.setImageDrawable(frameAnimation);
frameAnimation.start();
}
--
The frame animation will work, but unable to set the duration,
AnimationDrawable.scheduleDrawable() doesn't work.
