Android EditText not editable

I have a 2 activities with edittexts on them the first activity work fine but the second activity's EditText is focused but I can't edit it nor can I click the button on it.
Also everything works in the emulator but not when I install it on the device. (The keyboard popup also does not come up in the second activity where as it does in the first activity)
Below is the code for the1st and second activity

I just figured to re-create the app. I dont think it is a wise decision to copy the raw files to another directory and use that.

You do not invoke your custom private class
Change
webView.setWebViewClient(new WebViewClient());
to

So, I want to save the user input - the school name, so you don't have to type it every single time. But I can't really figure it out - can you please help me??? Thanks if you post me the full java file.

You can use the following:
SharedPreferences sp = getSharedPreferences("your_prefs", Activity.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.putString("clever_title", urlEditText.getText().toString());
editor.commit();
Then when you open your app the next time you can get:
SharedPreferences sp = getSharedPreferences("your_prefs", Activity.MODE_PRIVATE);
urlEditText.text(sp.getString("clever_title", null);

Displaying Menu items through webview in android application

I am new to Android application development and still learning. I have created a simple web app using webview and that is working well now I have created a menu in my app and trying to add an about and help and exit item on that. Now I would like them to open inside another webview or the existing webview that I have created. I am confused that should I create another method or a class or another way you prefer
I mean when I will choose about from menu then I will be redirected to a page in my asset folder called about.html and for help it will be help.html .
this is my MainActivity.java
package com.example.mywebapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.Window;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends Activity {
private WebView mWebView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
mWebView = new WebView(this);
mWebView.loadUrl("file:///android_asset/index.html");
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
this.setContentView(mWebView);
}
// For Options Menu
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.about:
// Then it should redirect to "file:///android_asset/about.html"
return true;
case R.id.help:
// Then it will be redirect to "file:///android_asset/help.html"
return true;
case R.id.exit:
finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public boolean onKeyDown(final int keyCode, final KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}

android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>

Found a solution
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.about:
startActivity(new Intent(this, About.class));
return true;
case R.id.exit:
finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
and then creating a About.class with these code
package com.example.mywebapp;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class About extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
webView = (WebView) findViewById(R.id.webView);
//webView.getSettings().setJavaScriptEnabled(true);
//webView.loadUrl("http://www.google.com");
webView.loadUrl("file:///android_asset/about.html");
}
}
and finally in AndroidManifest
<activity
android:name=".About"
android:theme="#android:style/Theme.NoTitleBar" />
i hope this ans would help newbie like me ...
