نمایش فایل html در fragment ( حل شد + سرس کد )

حل شد .

سورسشو میذارم شاید به کسی کمک کرد :)

 package test.iran;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.LinearLayout;

public class BookActivity extends Fragment {

    private WebView webView;
    private Bundle webViewBundle;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    LinearLayout ll = (LinearLayout) inflater.inflate(R.layout.show,
        container, false);

    webView = (WebView) ll.findViewById(R.id.webView1);
    webView.setWebViewClient(new WebViewClient());

    if (webViewBundle == null) {
        webView.loadUrl("file:///android_asset/content/session2.html");
    } else {
        webView.restoreState(webViewBundle);
    }

    return ll;

    }

    @Override
    public void onPause() {
    super.onPause();

    webViewBundle = new Bundle();
    webView.saveState(webViewBundle);
    }
}

کد xml: 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/tab2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:gravity="center">

    <WebView
        android:id="@+id/webView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>
