Android WebView progress bar

Question

I have looked at a question similar to this here but as I am a newbie could someone explain how to get this to work in a WebView or at least how to set a 10 second time delay so people know that it's loading?

For a horizontal progress bar, you first need to define your progress bar and link it with your XML file like this, in the onCreate:

final TextView txtview = (TextView)findViewById(R.id.tV1); final ProgressBar pbar = (ProgressBar) findViewById(R.id.pB1); 

Then, you may use onProgressChanged Method in your WebChromeClient:

MyView.setWebChromeClient(new WebChromeClient() {             public void onProgressChanged(WebView view, int progress) {                if(progress < 100 && pbar.getVisibility() == ProgressBar.GONE){                    pbar.setVisibility(ProgressBar.VISIBLE);                    txtview.setVisibility(View.VISIBLE);                }                 pbar.setProgress(progress);                if(progress == 100) {                    pbar.setVisibility(ProgressBar.GONE);                    txtview.setVisibility(View.GONE);                }             }         }); 

After that, in your layout you have something like this

<TextView android:text="Loading, . . ."      android:textAppearance="?android:attr/textAppearanceSmall"     android:id="@+id/tV1" android:layout_height="wrap_content"     android:layout_width="wrap_content"     android:textColor="#000000"></TextView>  <ProgressBar android:id="@+id/pB1"     style="?android:attr/progressBarStyleHorizontal" android:layout_width="fill_parent"     android:layout_height="wrap_content" android:layout_centerVertical="true"     android:padding="2dip"> </ProgressBar> 

This is how I did it in my app.

I have just found a really good example of how to do this here: http://developer.android.com/reference/android/webkit/WebView.html . You just need to change the setprogress from:

activity.setProgress(progress * 1000); 

to

activity.setProgress(progress * 100);
