利用webview实现在andorid中嵌入swf
这篇继续说说通过html模板的方式来嵌入SWF,这样做的好处最直观的就是可以把html,swf和android代码串起来,交互操作很方便(虽然这样最后没实现我最终的需求)
代码比较简单,上代码自己看吧
MainActivity
package com.example.flashdemo;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.webkit.JsResult;

import android.widget.FrameLayout;
public class MainActivity extends Activity {
private FrameLayout mFullscreenContainer;
private FrameLayout mContentView;
private View mCustomView = null;
private WebView mWebView;
private Handler mHandler = new Handler();
private ProgressDialog mProgressDialog;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initViews();
initWebView();
if (getPhoneAndroidSDK() >= 14) {// 4.0需打开硬件加速
getWindow().setFlags(0x1000000, 0x1000000);
}
mWebView.addJavascriptInterface(new DemoJavaScriptInterface(), "demo");
mWebView.loadUrl("file:///android_asset/videoTem.html");
// mWebView.loadUrl("file:///android_asset/NewSampleClient.html");
}
private void initViews() {
mFullscreenContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
mContentView = (FrameLayout) findViewById(R.id.main_content);
mWebView = (WebView) findViewById(R.id.webview_player);
//如果webView中需要用户手动输入用户名、密码或其他，则webview必须设置支持获取手势焦点。
mWebView.requestFocusFromTouch();
}
private void initWebView() {
WebSettings settings = mWebView.getSettings();
//设置此属性，可任意比例缩放
settings.setUseWideViewPort(true);//将图片调整到适合webview的大小
settings.setLoadWithOverviewMode(true);
//打开页面时， 自适应屏幕：
settings.setBuiltInZoomControls(true);
settings.setSupportZoom(true);//支持缩放
settings.setJavaScriptEnabled(true);//支持js
settings.setJavaScriptCanOpenWindowsAutomatically(true);
settings.setPluginState(PluginState.ON);
settings.setPluginsEnabled(true);//支持插件
settings.setAllowFileAccess(true);
mProgressDialog=ProgressDialog.show(this, "请稍等...", "加载flash中...", true);
mWebView.setWebChromeClient(new MyWebChromeClient());
mWebView.setWebViewClient(new MyWebViewClient());
}
class MyWebChromeClient extends WebChromeClient {

.setMessage(message)
.setPositiveButton("确定", null)
.setCancelable(false)
.create()
.show();
result.confirm();
return true;
}
@Override
public void onProgressChanged(WebView view, int newProgress) {
// TODO Auto-generated method stub
super.onProgressChanged(view, newProgress);
System.out.println("newProgress:"+String.valueOf(newProgress));
if(newProgress==100){
new Handler().postDelayed(new Runnable() {
@Override

mProgressDialog.dismiss();
}

}
}

setRequestedOrientation(mOriginalOrientation);
}
}
class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return super.shouldOverrideUrlLoading(view, url);
}
}
public static int getPhoneAndroidSDK() {
int version = 0;
try {
version = Integer.valueOf(android.os.Build.VERSION.SDK);
} catch (NumberFormatException e) {
e.printStackTrace();
}
return version;
}
final class DemoJavaScriptInterface {
DemoJavaScriptInterface() {
}
/**
* This is not called on the UI thread. Post a runnable to invoke
* loadUrl on the UI thread.
*/
public void clickOnAndroid() {
mHandler.post(new Runnable() {
public void run() {
mWebView.loadUrl("javascript:wave('111','192.168.0.28')");
}
});
}
}
}
模板也提供一下
<script>
function getPolicyNo()
{
alert(111);
//var policyNo = policyNodocument.getElementById("policyNo").value;
//return policyNo;
}
function getPrimaryServerIp()
{
//var primaryServerIp = document.getElementById("primaryServerIp").value
//alert(primaryServerIp);
//return primaryServerIp;
}
function wave(policyNo,primaryServerIp) {
document.getElementById("policyNo").value = policyNo;
document.getElementById("primaryServerIp").value = primaryServerIp;
}
</script>
<html>
<head>
<meta charset="utf-8" />
<title>swf</title>
</head>
<body onload="window.demo.clickOnAndroid()">
<embed src="NewSampleClient.swf"
bgcolor="#000000" width="80%" height="80%" align="middle"
allowScriptAccess="always" allowFullScreen="true" wmode="transparent"
type="application/x-shockwave-flash"> </embed>
<input type="hidden" id="policyNo" value="" />
<input type="hidden" id="primaryServerIp" value="" />
</body>
</html>
布局文件也弄一下
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="@+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
<FrameLayout
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="@+id/webview_player"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="horizontal" />
</FrameLayout >
</FrameLayout>
最新实现实时RTMP播放还是参照网上的一个开源库实现的,这个在下一篇介绍
