本文讲述了如何在Unity中调用Android中的WebView组件,实现内部浏览器样式的页面切换。首先打开Eclipse创建一个Android的工程:
UnityTestActivity.java 入口Activity ,Unity中会调用这个Activity中的方法从而打开网页。

package com.xys;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import com.unity3d.player.UnityPlayerActivity;
public class UnityTestActivity extends UnityPlayerActivity {
Context mContext = null ;
@Override
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
mContext = this ;
}
//Unity中会调用这个方法,从而开打WebView
public void StartWebView(String str)
{
Intent intent = new Intent(mContext,WebViewActivity. class );
this .startActivity(intent);
}
}
|
WebViewActivity.java Unity中发出通知打开这个Activity 继而打开WebView,没有什么难点大家看看就应当能掌握。

package com.xys;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.widget.Button;
public class WebViewActivity extends Activity
{
private WebView webView;
private Button close;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super .onCreate(savedInstanceState);
setContentView(R.layout.main);
webView = (WebView) findViewById(R.id.webView);
webView.loadUrl( "http://www.baidu.com/" );
webView.getSettings().setJavaScriptEnabled( true );
webView.setWebViewClient( new WebViewClient());
close = (Button) findViewById(R.id.button);
close.setOnClickListener( new OnClickListener() {
@Override
public void onClick(View v) {
WebViewActivity. this .finish();
}
});
}
private class WebViewClient extends android.webkit.WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
//这里实现的目标是在网页中继续点开一个新链接,还是停留在当前程序中
view.loadUrl(url);
return super .shouldOverrideUrlLoading(view, url);
}
}
}

然后是main.xml

<? xml version = "1.0" encoding = "utf-8" ?>
< LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent"
android:orientation = "vertical" >
< WebView
android:id = "@+id/webView"
android:layout_width = "fill_parent"
android:layout_height = "wrap_content"
android:layout_weight = "1.0"
/>
< Button
android:id = "@+id/button"
android:text = "关闭网页"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
/>
</ LinearLayout >
|
最后是AndroidManifest.xml

OK 到这里JAVA代码已经完全写完,然后把所有.JAVA文件打包变成.class文件,具体转换的方法大家可以参照相关的文章,这里就不再重复介绍了。
