离开 WebView 后如何停止 Flash? [英] How do I stop Flash after leaving a WebView?

问题描述

我有一个应用程序，当用户单击按钮时，我将其放在一起以在 web 视图中流式传输 Flash 视频.

I have an app that I've put together to stream flash video in a webview when a user clicks a button.

它做得很好，但在退出或失去焦点后，它看起来会继续使用数据一段时间，直到我假设系统关闭活动.如果我手动退出活动屏幕，数据使用几乎立即停止.只需退出，它就可以继续运行一段时间.

It does this fine, but after backing out or losing focus, it looks like it continues to use data for a while until I assume when the system shuts the activity down. If I manually kill out of the activity screen, data use stops almost immediately. Just backing out and it can keep going for a while.

谁能帮我解决我的代码，我真的很感激！

Can someone help me out with my code, I would really appreciate it!

import java.lang.reflect.Method;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;

public class Video extends Activity {


    private WebView webview;


    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.video);


    webview = (WebView) findViewById(R.id.webview);

// resumeTimers() to account for the webview refcount bug (hopefully)
    webview.resumeTimers();
    WebSettings webSettings = webview.getSettings();
    webview.getSettings().setJavaScriptEnabled(true);
    webSettings.setPluginsEnabled(true);
    webview.setVerticalScrollBarEnabled (false);
    webview.setHorizontalScrollBarEnabled (false);

    webview.loadUrl("http://www.nasa.gov/multimedia/nasatv/nasatv_android_flash.html");
}


@Override
protected void onPause() {
pauseBrowser();
super.onPause();
}

@Override
protected void onResume() {
resumeBrowser();
super.onResume();
}



private void pauseBrowser() {

// pause flash and javascript etc
callHiddenWebViewMethod(webview, "onPause");
webview.pauseTimers();
}

private void resumeBrowser() {

// resume flash and javascript etc
callHiddenWebViewMethod(webview, "onResume");
webview.resumeTimers();
}

private void callHiddenWebViewMethod(final WebView wv, final String name){
    if( webview != null ){
        try {
            Method method = WebView.class.getMethod(name);
            method.invoke(webview);
        } catch (final Exception e) {
        }
    }
}

}

推荐答案

我对这个问题有点困惑，但我认为您是说 Flash 视频即使在 Activity 关闭后仍继续播放.我遇到了类似的问题.以下对我有用:

I'm a bit confused by the question, but I think you're saying that flash video keeps on playing even after the activity is closed. I ran into a similar issue. The following worked for me:

@Override
protected void onDestroy() {
    super.onDestroy();
    final WebView webview = (WebView)findViewById(R.id.webPlayer);
    // Calling .clearView does not stop the flash player must load new data
    webview.loadData("", "text/html", "utf-8");
}

我在这里发布了同样的解决方案:android WebView stop Flash plugin onPause
