android - 即使列表处于空闲状态，如何连续为 ListView 项目设置动画

Question

我想ListView用不同的动画为每个项目设置动画，即使列表处于空闲状态，即它不是滚动或翻转状态。我只知道它可以通过连续动画来完成，但它不能正常工作Handler。Runnable请为此提出一些建议。

在自定义 adpater 的 getview 方法中添加动画。像这样，

      @Override
      public View getView(final int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);



        View rowView = inflater.inflate(R.layout.simple_row, parent, false);
        ImageView image = (ImageView) rowView.findViewById(R.id.image);

       if(position==0)
{
        mAnimation = new TranslateAnimation(
                TranslateAnimation.ABSOLUTE, 0f,
                TranslateAnimation.ABSOLUTE, 0f,
                TranslateAnimation.RELATIVE_TO_PARENT, 0f,
                TranslateAnimation.RELATIVE_TO_PARENT, 1.0f);
       mAnimation.setDuration(10000);
       mAnimation.setRepeatCount(-1);//here we set repeat count to unlimited, so that the animation will run continuously 
       mAnimation.setRepeatMode(Animation.REVERSE);
       mAnimation.setInterpolator(new LinearInterpolator());
       image.setAnimation(mAnimation);

}

else if(position==1)
{
//your second animation
}


     return rowView;
  }
