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

Answer

To be precise, you can try following change:

public void openBrowser(){
    //Ensure that URL entered is a valid one
    mWebView.loadUrl(text.getText().toString());
}
