Question

（抱歉我的英文不太好......希望你能理解我）

我的朋友是一个非常好的抽屉。我想帮助他成为一个好抽屉，让他成为一个用他的绘画动画的动态壁纸。

我希望他画几帧并使用这些帧来制作动态壁纸，一个接一个地显示它们。

我正在努力展示一张图片，然后等一下再显示下一张图片。我很确定我不能成功，因为我没有采用正确的方法......

这是我迄今为止所做的事情：

public class Cercle extends WallpaperService
{
public void onCreate() 
{
    super.onCreate();
}

public void onDestroy() 
{
    super.onDestroy();
}

public Engine onCreateEngine() 
{
    return new CercleEngine();
}

class CercleEngine extends Engine 
{
    public Bitmap image1, image2, image3;

    CercleEngine() 
    {       
        image1 = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
        image2 = BitmapFactory.decodeResource(getResources(), R.drawable.img2);
        image3 = BitmapFactory.decodeResource(getResources(), R.drawable.img3); 
    }

    public void onCreate(SurfaceHolder surfaceHolder) 
    {
        super.onCreate(surfaceHolder);
    }

    public void onOffsetsChanged(float xOffset, float yOffset, float xStep, float yStep, int xPixels, int yPixels) 
    {
        drawFrame();
    }

    void drawFrame() 
    {
        final SurfaceHolder holder = getSurfaceHolder();

        Canvas c = null;
        try 
        {
            c = holder.lockCanvas();
            if (c != null) 
            {              
                 c.drawBitmap(image1, 0, 0, null);
                 c.drawBitmap(image2, 0, 0, null);
                 c.drawBitmap(image3, 0, 0, null);                   
            }
        } finally 
        {
            if (c != null) holder.unlockCanvasAndPost(c);
        }
    }
}
}

这段代码只是显示图片的速度太快，因为我不知道如何在二次拼图之间等待......

有人可以给我一些提示或给我一些其他解决方案的例子吗？

非常感谢！

更新：

我通过添加Runnable解决了我的问题：

private final Runnable drawRunner = new Runnable() 
    {
        @Override
        public void run() {
            drawFrame();
        }

    };

然后添加：

    handler.removeCallbacks(drawRunner);
        if (visible) 
        {
           handler.postDelayed(drawRunner, 1000); // delay 1 sec
        }

在drawFrame（）的末尾。

希望这会对某人有所帮助。

使用此开源项目为您的朋友创建精美的动态壁纸

link它是从电话库中读取的，您可以将其编辑为从项目中的文件夹中读取，只需按原样使用。

或将此link用于其他动态壁纸项目

@Pozinux ...我是一名新程序员。我遇到了你听过的这段代码。我正在尝试在我的项目中使用代码。但我无法让它发挥作用。当我将它安装到模拟器时，它不会移动它的帧。它只显示最后一帧。你是怎么设置的？或者让这个工作？听听我在项目中如何设置它。
