js切换video的src（videojs切换视频）

<video id="dsp_video" type="video/mp4"poster="" controls="controls" preload="none">
	<source id="mysource" src=""></source>
	你的浏览器不支持video播放
</video>
<script type="text/javascript">
	$(".try").each(function(index){
		$(this).click(function(e){				
			//$("#dsp_video>source").attr("src",videoList[index]);  //注意切换source的src无效
			$("#dsp_video").attr("src",videoList[index]);  //必须切换video标签的src
			$("#video_wrap").show();
		});
	});

Android VideoView,需要快速切换视频

我正在开发一个新的应用程序,并使用VideoView显示mpeg剪辑.

我需要非常快速地在视频之间切换,但是,将新剪辑加载到VideoView似乎需要大约半秒的黑屏.

过渡必须是无缝的,你将如何解决这类问题？

解决方法

我有一个类似的问题,并解决了静态图像( ImageView)转换：

>使用VideoView通过VideoView构建FrameLayout
> ImageView显示视频的第一帧
>最初ImageView是可见的
>启动视频,等待任意时间(例如2-300ms)
>隐藏ImageView

切换两个视频：
– 显示图像
– 切换视频
– 隐藏图像

有点hackish但为我工作

android – VideoView内联/全屏模式切换

我正在研究android中的一个自定义视频播放器.我正在使用VideoView播放视频.最初我的VideoView将具有一定的尺寸(比方说尺寸=(宽度,高度)=(400,300)).我的自定义视频视图的控制按钮之一是“展开/折叠”.单击“展开/折叠”按钮后,我想将VideoView大小设置为全屏(表示设备的全屏大小),如果当前VideoView大小为内联,反之亦然(从全屏到内联也是如此).

有人知道完成上述任务的正确方法吗？

解决方法:

首先,你有胆量问一个Android问题,并有一个iOS徽标;)(开玩笑)

但是,我认为你可以使用这个：

    displayMetrics metrics = new displayMetrics(); getwindowManager().getDefaultdisplay().getMetrics(metrics);
    android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
    params.width =  metrics.widthPixels;
    params.height = metrics.heightPixels;
    params.leftMargin = 0;
    videoView.setLayoutParams(params);

并将其设置回：

    displayMetrics metrics = new displayMetrics(); getwindowManager().getDefaultdisplay().getMetrics(metrics);
    android.widget.LinearLayout.LayoutParams params = (android.widget.LinearLayout.LayoutParams) videoView.getLayoutParams();
    params.width =  (int) (400*metrics.density);
    params.height = (int) (300*metrics.density);
    params.leftMargin = 30;
    videoView.setLayoutParams(params);

我假设您知道如何制作OnClickListener.

我在这里得到的信息：VideoView Full screen in android application

EDIT1
我可以很快想到两件事.
1.添加：getwindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
2.或试试这个：

YourButton.setVisibility(View.GONE);

要么

YourButton.setVisibility(View.INVISIBLE);

android-layout – 切换vs切换

我正在尝试决定是使用开关还是切换来设置闹钟我是我的 Android应用程序.对于相当新的Android并且不了解或完全理解框架工作的所有细节.选择通过切换开关触发警报的缺点是什么,反之亦然？ android框架中是否有滑动切换功能？

解决方法

您需要记住的第一件事是,您想要编译您的应用程序的API？

由于API 1和Switches仅在API 14之后可用,因此可以使用Toggle Buttons.

除此之外,这只是一个简单的决定,哪一个是用户界面/设计的最佳选择
在我看来,交换机清楚地表明了当前选择的内容.

Is there a slide toggle available in android framework?

是的,开关可以用作幻灯片切换.

代码非常简单,基本上可以对这两个按钮使用相同的思路.

这是一个切换按钮的示例

btnSwitch = (Switch) findViewById(R.id.switch_1);

btnSwitch.setonCheckedchangelistener(new OnCheckedchangelistener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
        if (isChecked) {
            Log.i("Switch","ON");
        } else {
            Log.i("Switch","OFF");
        }
    }
});

这是一个切换按钮的示例

btnToggle = (ToggleButton) findViewById(R.id.toggle_1);

btnToggle.setonCheckedchangelistener(new OnCheckedchangelistener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
        if (isChecked) {
            Log.i("Toggle","ON");
        } else {
            Log.i("Toggle","OFF");
        }
    }
});
