的WebView不开放的Android默认视频播放器? [英] WebView NOT opening android default video player?
问题描述
当我查看此页面在我的Android设备默认的Web浏览器,单击第一个视频,它触发我的设备的默认视频播放器。它加载和播放。
然而,当我看到相同的链接在我的应用程序,使用web视图,它不会打开默认的视频播放器。可能是什么问题?
我使用的WebView code中的这个链接。
我也发了的WebView在全屏模式下喜欢什么在文档有人说,使用该code去全屏:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
编辑:我现在用下面的code,但仍然无法正常工作,任何想法

返回true;
}
否则返回false;
}});
//这将加载,我们希望看到的网页
webview.loadUrl(http://www.broken-links.com/2010/07/30/encoding-video-for-android/);
}
}
您必须附上自己的 WebViewClient
并覆盖 shouldOverrideUrlLoading()
如果发现网址有支持的视频MIMETYPE返回true,然后启动默认的活动的URL。下面是一个未经测试的样本。
mWebView.setWebViewClient(新WebViewClient(){
公共布尔shouldOverrideUrlLoading(web视图查看,字符串URL){
如果(url.endsWith(MP4)|| url.endsWith(其他支持的类型)){
意图I =新的意图(Intent.ACTION_VIEW);
i.setData(Uri.parse(URL));
startActivity(ⅰ); //警告没有错误处理将导致强制关闭,如果在电话中没有任何的媒体播放器。
返回true;
}
否则返回false;
}});
希望这会有所帮助。
when I view this page on my android device' default web browser and click the first video, it triggers the default video player of my device. It loads and play.
However when I view the same link in my app, using a WebView, it does not open the default video player. What could be the problem?
I'm using the webview code in this link.
I also made the webview in full screen mode like what was said in the docs, is used this code to go fullscreen:
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
EDIT: I'm now using the following code, but still not work, any ideas?
package com.example.Playmp4OnWebView;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class PlayMp4OnWebView extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
WebView webview = new WebView(this);
setContentView(webview);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(false);
webSettings.setPluginsEnabled(true);
webSettings.setAllowFileAccess(true);
webview.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url){
if(url.endsWith(".mp4")){
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i); //warning no error handling will cause force close if no media player on phone.
return true;
}
else return false;
}});
//This will load the webpage that we want to see
webview.loadUrl("http://www.broken-links.com/2010/07/30/encoding-video-for-android/");
}
}
You have to attach your own WebViewClient
and override shouldOverrideUrlLoading()
if you detect a URL with a supported video mimetype return true and then launch the default activity with the URL. Here is an untested sample.
mWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(Webview view, String url){
if(url.endsWith(".mp4") || url.endsWith("some other supported type")){
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i); //warning no error handling will cause force close if no media player on phone.
return true;
}
else return false;
}});
hope this helps.
