Unity3D游戏引擎实现在Android中打开WebView的实例

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);     }  }

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);      }    }  }
