Hi I am new to Android development and StackOverflow.

I have an Android WebView application in which a 'starter activity' (just intro text and a button to start main intent) starts my WebView activity, which loads a single URL (this is in the onCreate method). 

In this main activity, I have three buttons, one of which opens the same URL in the current activity (effectively refreshing the page). The other two buttons I would like to open two different URLs in the same WebView activity, and I was wondering if/how this is possible.

Here is the main ReadWebpageAsyncTask.java activity code:

```
public class ReadWebpageAsyncTask extends Activity {

  private WebView browser;
  protected String urlStrOne = "url one";
  protected String urlNewCourses = "url two";
  protected String urlFutureCourses = "url three";

  @Override     
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_read_webpage_async_task);
  browser = (WebView)findViewById(R.id.WebView01);
  browser.setWebViewClient(new MyBrowser());
  browser.loadUrl(urlStrOne);
  }

  @SuppressLint("SetJavaScriptEnabled")
  public void onClick(View view){
  browser.getSettings().setLoadsImagesAutomatically(true);
  browser.getSettings().setJavaScriptEnabled(true);
  browser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
  browser.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
  browser.loadUrl(urlStrOne);
  }

  private class MyBrowser extends WebViewClient {
  @Override
  public boolean shouldOverrideUrlLoading(WebView browser, String urlStrOne) {
     browser.loadUrl(urlStrOne);
     return true;
  }
  }   

  @Override
    // Detect when the back button is pressed
    public void onBackPressed() {
        if(browser.canGoBack()) {
            browser.goBack();
        } else {
       // Let the system handle the back button
       super.onBackPressed();
        }
  }
  }

```

And the corresponding XML:

```
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="left|right"
android:orientation="vertical" >

<RelativeLayout 
android:id="@+id/relativeLayout1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/black">

<Button
    android:id="@+id/readWebpage"
    android:layout_width="100dp"
    android:layout_height="50dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:layout_toLeftOf="@+id/soon"
    android:background="@+drawable/custom_button_one"
    android:onClick="onClick"
    android:text="@string/load_page" />

<Button
    android:id="@+id/exitapp01"
    android:layout_width="100dp"
    android:layout_height="50dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_toRightOf="@+id/soon"
    android:background="@+drawable/custom_button_one"
    android:onClick="exitButton"
    android:text="@string/exit_button" />

<Button
    android:id="@+id/soon"
    android:layout_width="100dp"
    android:layout_height="50dp"
    android:layout_toLeftOf="@+id/exitapp01"
    android:layout_toRightOf="@+id/readWebpage"
    android:layout_alignParentTop="true"
    android:onClick="comingSoon"
    android:text="@string/future_courses" />

    </RelativeLayout>

<WebView
    android:id="@+id/WebView01"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="@string/WebView01" >

</WebView>
</LinearLayout>

```

P.S. Please excuse the terrible naming of everything, I wrote this a while back and haven't gotten around to changing it all.

To clarify, the main URL which is loaded first is the same as the button "readWebpage", and the other two URLs which I would like to be loaded on click are buttons "exitapp01" (what can I say, I am a noob) and "soon".
