WebView textarea doesn"t pop up the keyboard

When I display a WebView , I don't see the soft keyboard popping up. The hard keyboard also doesn't work!

What are the usual shortcomings.

The code which I use to access the WebView is:

package com.example.blahblah;



import android.app.Activity;

import android.content.Intent;

import android.content.SharedPreferences;

import android.os.Bundle;

import android.os.Handler;

import android.preference.PreferenceManager;

import android.util.Log;

import android.view.KeyEvent;

import android.view.Window;

import android.webkit.JsResult;

import android.webkit.WebChromeClient;

import android.webkit.WebSettings;

import android.webkit.WebView;

import android.webkit.WebViewClient;

import android.widget.Toast;



public class createAccount extends Activity {



private static final String LOG_TAG = "Create Account";

private WebView mWebView;

private static final String URL = blah_app.urlSelected+"createAccount.html";    

private Handler mHandler = new Handler();



@Override

public void onCreate(Bundle icicle) {

    super.onCreate(icicle);

    Toast.makeText(createAccount.this, "URL = " +URL, Toast.LENGTH_SHORT).show();

    getWindow().requestFeature(Window.FEATURE_PROGRESS);

    setContentView(R.layout.webview);

    getWindow().setFeatureInt(Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);



    mWebView = (WebView) findViewById(R.id.webview);



    WebSettings webSettings = mWebView.getSettings();

    webSettings.setSavePassword(true);

    webSettings.setSaveFormData(true);

    webSettings.setJavaScriptEnabled(true);

    webSettings.setSupportZoom(true);





    final Activity activity = this;

    mWebView.setWebChromeClient(new WebChromeClient() {

    public void onProgressChanged(WebView view, int progress) {



        activity.setProgress(progress * 1000);

      }

    });



    mWebView.addJavascriptInterface(new DemoJavaScriptInterface(), "demo");

    mWebView.clearCache(true);

    setProgressBarVisibility(true);

    mWebView.setWebViewClient(new WebViewClient() {

          public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {

            Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();

          }



           @Override  

           public void onPageFinished(WebView view, String url)  

           {  

               mWebView.loadUrl("javascript:(function () { " +

                       "setVariables("+blah_app.numberSelected+",'"+blah_app.urlSelected+"');" +

                       "})()");

           }

        });



    mWebView.loadUrl(URL);

}



final class DemoJavaScriptInterface {



    public void setData(String fname, String lname, String gacct, String phone) {



        SharedPreferences prefCreateAccount = PreferenceManager.getDefaultSharedPreferences(createAccount.this);

        SharedPreferences.Editor editor = prefCreateAccount.edit();

        editor.putString("FirstName", fname);

        editor.putString("LastName", lname);

        editor.putString("GmailAcct", gacct);

        editor.putString("Phone", phone);

        editor.commit();    



    }

    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()");

            }

        });

    }

}



/**

 * Provides a hook for calling "alert" from javascript. Useful for

 * debugging your javascript.

 */

final class MyWebChromeClient extends WebChromeClient {

    @Override

    public boolean onJsAlert(WebView view, String url, String message, JsResult result) {

        Log.d(LOG_TAG, message);

        result.confirm();

        return true;

    }

}



public boolean onKeyDown(int keyCode, KeyEvent event) {

    if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {

        startActivity(new Intent(getApplication(), blah_app.class));

        return true;

    }

    return super.onKeyDown(keyCode, event);

}

}
