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);

How to load WebView in the same page

I have created an edittext and a go button and a webview in single layout. When a person enters a url and clicks on go button, the webview should load the website content, Instead it is going to default browser to load website how should i slove this issue ?
This is my code
xml file
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="50dip" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<EditText
android:id="#+id/etenterurl"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0"
android:inputType="textUri" />
<Button
android:id="#+id/buttongo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="3.0"
android:text="Go" />
</LinearLayout>
</FrameLayout>
java code :
import java.util.ArrayList;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.widget.Button;
import android.widget.EditText;
import android.annotation.SuppressLint;
import android.app.Activity;
public class MainActivity extends Activity {
EditText etenter;
Button bgo;
WebView webview;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etenter= (EditText)findViewById(R.id.etenterurl);
bgo =(Button)findViewById(R.id.buttongo);
webview = (WebView)findViewById(R.id.webview);
bgo.setOnClickListener(new View.OnClickListener() {
#SuppressLint("SetJavaScriptEnabled")
#Override
public void onClick(View v) {
String url=etenter.getText().toString();
if(url.trim().length()>0){
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://"+url);
}
}
});
}
}

You have to use WebViewClient
wbView.setWebViewClient(new MyWebViewClient());
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
Log.v("uuuurl",url);
view.loadUrl(url);
return true;
}
}
See here for example

you should use WebViewClient
webview.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d("TAG", " ==> "+url);
view.loadUrl(url);
return true;
}
});

WebView inside application?

So I have a WebView inside of a LinearLayout with an EditText Box and a Button to make the application search for the web. When I click go on my button it takes me to the stock android browser. how do I make It so that it stays within my WebView when I click go?
here is my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:id="#+id/web_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="http://"/>
<Button
android:id="#+id/go"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/go"
android:gravity="right"/>
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
here is my source:
package straightapp.com.Browser;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnKeyListener;
import android.webkit.WebView;
import android.widget.Button;
import android.widget.EditText;
public class Browser extends Activity {
WebView mWebView;
Button button;
EditText text;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.straightapp.com");
text=(EditText)findViewById(R.id.web_address);
button=(Button) findViewById(R.id.go);
button.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
// TODO Auto-generated method stub
openBrowser();
}
});
text.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
if (keyCode==KeyEvent.KEYCODE_ENTER){
openBrowser();
return true;
}
return false;
}
});
}
public void openBrowser(){
Uri uri=Uri.parse(text.getText().toString());
Intent intent=new Intent(Intent.ACTION_VIEW,uri);
startActivity(intent);
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
Thanks

When I click go on my button it takes me to the stock android browser.
That's because that is what you told Android to do. startActivity() starts an activity.
how do I make It so that it stays within my WebView when I click go?
Call loadUrl() on your WebView instead of calling startActivity().

To be precise, you can try following change:
public void openBrowser(){
//Ensure that URL entered is a valid one
mWebView.loadUrl(text.getText().toString());
}

Change your xml file as below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".Browser"> <!--Just add this line -->
<EditText
android:id="#+id/web_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="http://"/>
<Button
android:id="#+id/go"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/go"
android:gravity="right"/>
<WebView
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>

First declare the webview and progressbar
progressBar = (ProgressBar)findViewById(R.id.progressBar);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
Copy and paste this code below onCreate method
public class myWebClient extends WebViewClient {
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progressBar.setVisibility(View.VISIBLE);
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
