问题描述

嗨，我想为应用程序创建一个飞溅屏幕，并在计时器上旋转几张图像.谁能告诉我如何使用计时器在画廊中对图像进行动画?

推荐答案

一个简单的解决方案将是

private int PicPosition;
private Handler handler = new Handler();

... ... ...

private Runnable runnable = new Runnable() {
    public void run() {
        myslideshow();
        handler.postDelayed(this, 1000);\\execute every second.
    }
};

    private void myslideshow()
    {
                    PicPosition = gallery.getSelectedItemPosition() +1;             
                    if (PicPosition >=  Pictures.size())            
                    PicPosition =  gallery.getSelectedItemPosition(); //stop 
                                    else
                    gallery.setSelection(PicPosition);//move to the next gallery element.
    }
