在Android的Play.gif图像，而无需使用web视图 [英] Play.gif image in android without using webview

问题描述

我想是这样的，我发现在网络上播放GIF图像：

I tried like this, which i found on the net to play gif images:

private class MYGIFView extends View {

    Movie movie;
    InputStream is = null;
    long moviestart;

    public MYGIFView(Context context) {
        super(context);

        // Provide your own gif animation file

        is = context.getResources().openRawResource(R.drawable.mygif);
        movie = Movie.decodeStream(is);

    }

    @Override
    protected void onDraw(Canvas canvas) {

        canvas.drawColor(Color.WHITE);
        super.onDraw(canvas);
        long now = android.os.SystemClock.uptimeMillis();
        System.out.println("now=" + now);
        if (moviestart == 0) { // first time
            moviestart = now;

        }
        System.out.println("\tmoviestart=" + moviestart);
        int relTime = (int) ((now - moviestart) % movie.duration());
        System.out.println("time=" + relTime + "\treltime="
                + movie.duration());
        movie.setTime(relTime);
        movie.draw(canvas, this.getWidth() / 2 - 20,
                this.getHeight() / 2 - 40);
        this.invalidate();
    }

虽然很多人说，他们得到了他们想要的结果。

Though many have said that they got their desired result.

我已经把GIF图像的绘制。 我越来越movie.duration（）返回null。

I have put the gif image in drawable. I am getting movie.duration() null.

请建议我在哪里错了，或者是有什么办法。

Please suggest where am i wrong or if is there any way.

推荐答案

没有的WebView Android无法播放GIF文件。你必须仔细分解成框架，并自己制作动画。

Android cannot play GIF files without WebView. You must break it apart into frames and animate it yourself.

我发现了另一个计算器后该位从XoyoSoft ，叫GifSplitter软件，能够分裂GIF格式为帧。这样，你会希望使用 AnimationDrawable 结合这些。

I found on another StackOverflow post this bit of software from XoyoSoft, called GifSplitter, that can split a GIF into frames. You would then want to use AnimationDrawable to combine those.

这将是这个样子：

// Your files:
res\drawable-xxxx\frame1.jpg
res\drawable-xxxx\frame2.jpg
res\drawable-xxxx\frame3.jpg
// ...
res\drawable-xxxx\frame99.jpg

那么，有 AnimationDrawable 文档上面的例子将展示如何显示这些图像。

Then, there is an example in the AnimationDrawable documentation above that will show how to display those images.

最后，你必须加载和播放动画;这也被详细介绍了 AnimationDrawable 文档。

Lastly, you must load and play the animation; that, too, is detailed in the AnimationDrawable documentation.
