我正在尝试在Android模拟器中播放视频我在我的资源文件夹中的视频以及原始文件夹但是在做了一些研究后仍然无法在我的模拟器中播放视频我正在使用android 2.1我的视频格式是mp4所以我不要认为这应该是一个问题任何人都可以给我一个示例代码,以便我可以了解更多？问题是我需要显示视频的VideoView只会使用URI或文件路径指向视频. 如果我将视频保存在raw或assets文件夹中,我只能获得输入流或文件描述符,似乎没有什么可用于初始化VideoView.更新我仔细研究了MediaPlayer示例,并尝试使用FileDescriptor启动MediaPlayer到资源文件,如下面的代码所示:SurfaceView videoView = (SurfaceView) findViewById(gettingStarted)
SurfaceHolder holder = videoView.getHolder();
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
final MediaPlayer player = new MediaPlayer();
player.setDisplay(holder);
player.setDataSource(getAssets().openFd(fileName).getFileDescriptor());
player.prepareAsync();
player.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
Run Code Online (Sandbox Code Playgroud)现在我得到以下异常: java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed
Run Code Online (Sandbox Code Playgroud)似乎没有其他方法可以在启动时将文件复制到SD卡,这似乎浪费时间和内存.

展开全部1，所下的视频要能在手机上播放，也就是视频格式要和手机允许的，能放的一样才行。2，比如wmv、rmvb等格式一般都只能在电脑上播放，一般的手机就不一定能放。3，这时就可用视频转换器，把它转换一下，比如适合手机播放的3gp制式等就可以播放了。4，如果不会转换，可网上直接搜找能播放的格式视频。5，如果要找转换器软件，可在网上搜“视频转换器软件”之类，会有很多的。6，建议最好看一下本手机说明书，了解本手机什么格式的视频能播放，就会省事多了。',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign),e.getAttribute("jubao"))},getILeft:function(t,e){return t.left+e.offsetWidth/2-e.tip.offsetWidth/2},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#href\}\}/g,e).replace(/\{\{#jubao\}\}/g,n)}},baobiao:{triangularSign:"data-baobiao",tpl:'{{#baobiao_text}}',getTip:function(t,e){return t.renderTip(e.getAttribute(t.triangularSign))},getILeft:function(t,e){return t.left-21},getSHtml:function(t,e,n){return t.tpl.replace(/\{\{#baobiao_text\}\}/g,e)}}};function l(t){return this.type=t.type
