[原]unity3d调用android webView

1、配置dialog xml文件：

<resources>
<style name="dialogStyleWindow" parent="@android:style/Theme.Dialog">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:background">@android:color/transparent</item>
<item name="android:windowBackground">@android:color/transparent</item>
</style>
</resources>

2、创建布局xml notice.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />

<ImageView
android:id="@+id/close"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/btn_close" />
</RelativeLayout>

3、代码实现：

import android.app.Activity;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.view.Display;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.WindowManager;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ImageView;

public class Notice {

Activity mActivity;
Dialog noticeDialog = null;
WebView webView;
ProgressDialog dialog;

//在主activity中调用 传this进来
public Notice(Activity activity) {
mActivity = activity;
}

//u3d 调用这个函数显示webview 线程问题 建议通过handler方式调用
public void show() {
if(noticeDialog == null){
noticeDialog = new Dialog(mActivity,R.style.dialogStyleWindow);
}
View contentView = mActivity.getLayoutInflater().inflate(R.layout.notice,null);

ImageView closeBtn = (ImageView) contentView
.findViewById(R.id.close); //关闭当前webview
closeBtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub

noticeDialog.dismiss();
webView = null;
noticeDialog = null;
}
});

dialog = ProgressDialog.show(mActivity,null,"正在进入网页，请稍后…");
webView =(WebView)contentView.findViewById(R.id.webView1);
webView.loadUrl("http://www.baidu.com");
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());

noticeDialog.setContentView(contentView);
noticeDialog.setCanceledOnTouchOutside(false);
noticeDialog.show();

//设置webview全屏
WindowManager windowManager = mActivity.getWindowManager();
Display display = windowManager.getDefaultDisplay();
WindowManager.LayoutParams lp = noticeDialog.getWindow().getAttributes();
lp.width = (int)(display.getWidth()); //设置宽度
lp.height = (int)(display.getHeight());
noticeDialog.getWindow().setAttributes(lp);
}
private class WebViewClient extends android.webkit.WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}

@Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub

dialog.dismiss();
}
}

}
