Android - 播放html5<视频>在HTML代码中 [英] Android - playing html5 <video> in html code

问题描述

我知道有很多关于此的旧讨论，但我正在为新设备开发。

I know there are a lot of old discussion about this, but I am developing for new devices.

我想使用WebView在视频标签中显示html5视频。我想用这个Android设备4.0+甚至4.1+。

I want to use WebView to show html5 video in video tag. I want to use this for android devices 4.0+ or even 4.1+.

我不想更改WebView代码。是否可以在WebView中显示电影而无需在顶部打开一些新视图？因为大多数答案都开启了播放视频的新视角？我需要尽可能少的代码更正来轻松解决问题。

I do not want to change the WebView code a lot. Is it possible to show movie in WebView without opening some new views on top? Because most of the answers opened new view to play video? I need easy solution with as less as possible code corrections.

欢迎任何代码或教程。

Any code or tutorial will be welcome.

        webView.loadUrl(pageURL);

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

推荐答案

以下是我用于Android API15及更高版本的应用程序的片段，播放支持的视频类型（.mp4是最可靠的）。它可以从URL提供内容或在线创建（已注释掉）。

the following is a snippet from an application I have for Android API15 and above that plays supported video types (.mp4 is the most reliable). It can serve content from a URL or created in-line (commented out).

如果由此导致视频仍无法播放，您是否可以发布链接这里我们可以检查它是否兼容。

If, with this, the video still won't play, can you post a link to a sample here so we can check if it's compatible.

清单中需要以下内容

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

和

<application
android:hardwareAccelerated="true" 
.... />

然后代码：

package com.offbeatmammal.android.webview;

import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.widget.RelativeLayout;

public class WebViewActivity extends Activity {

private WebView webView;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview);

    webView = (WebView) findViewById(R.id.webView1);

    webView.setWebChromeClient(new WebChromeClient());
    webView.getSettings().setPluginState(WebSettings.PluginState.ON_DEMAND);
    webView.getSettings().setJavaScriptEnabled(true);

    // load the customURL with the URL of the page you want to display
    // String pageURL = "http://url/page.html";
    // webView.loadUrl(pageURL);

    String customHtml = "<html><head><title>Sample</title></head><body><video controls><source src='http://www.broken-links.com/tests/media/BigBuck.m4v'></video></body></html>";
    webView.loadData(customHtml, "text/html", "UTF-8");
}
}
