所以我实现了一段代码，它在另一个 thread 上完美运行
代码如下:
private void animate(final ImageView imageView, final int images[], final int imageIndex, final boolean forever){
//imageView <-- The View which displays the images
//images[] <-- Holds R references to the images to display
//imageIndex <-- index of the first image to show in images[]
//forever <-- If equals true then after the last image it starts all over again with the first image resulting in an infinite loop. You have been warned.
int fadeInDuration = 500; // Configure time values here
int timeBetween = 3000;
int fadeOutDuration = 1000;
imageView.setVisibility(View.INVISIBLE); //Visible of invisible by default
imageView.setImageResource(images[imageIndex]);
Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); //Add this
fadeIn.setDuration(fadeInDuration);
Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); //and this
fadeOut.setStartOffset(fadeInDuration + timeBetween);
fadeOut.setDuration(fadeOutDuration);
AnimationSet animation = new AnimationSet(false); //change to false
animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
animation.setRepeatCount(1);
imageView.setAnimation(animation);
animation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationEnd(Animation animation) {
if(images.length -1 > imageIndex){
animate(imageView, images, imageIndex + 1, forever); // Calls itself until it gets to the end of the array.
}
else{
if(forever == true){
animate(imageView, images, 0, forever); //Calls itself to start the animation all over again in a loop if forever = true
}
}
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
});
}
基本上，此代码接受图像数组并创建具有淡入淡出效果的幻灯片。一旦到达终点，动画就会停止。如何修改代码以永远保持动画效果？
最佳答案
伙计们找到了解决方案。
只需要稍微改动一下!在 else 语句中，我必须将 Forever 设置为 false!
else{
if(forever == false){
animate(imageView, images, 0, forever);
}
}
