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);
}
}

For making it easy, and as the other solutions have issues working on all devices or in all condition, I'm always using a small hack to overcome this issue without touching the code, just add any hidden editText to the layout contains the webView that will grant the focus to the whole view automatically and you will not have to worry about the webView text fields anymore:

<EditText
    android:id="@+id/kb_holder"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:inputType="text"
    android:maxLines="1"
    android:visibility="gone" />

So, the whole layout would be like:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText
        android:id="@+id/kb_holder"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:inputType="text"
        android:maxLines="1"
        android:visibility="gone" />

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

</FrameLayout>

override onPageFinished in WebViewClient

override fun onPageFinished(view: WebView?, url: String?) {
 
    // Show soft input automatically for specific search web page.
    if ("the_url_page".equals(url)) {
        view?.requestFocus()
        val imm: InputMethodManager? = view?.context?.getSystemService(INPUT_METHOD_SERVICE) as? InputMethodManager
            imm?.showSoftInput(view, 0)
    }
    super.onPageFinished(view, url)
}
