Apps ProgressBar problem?

[Grendizer]

Hi all

I'm having problem displaying my progressbar. It's suppose to show up when I download a file inside a WebView.
I'd appreciate any help here.

XML

<?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">


    <WebView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview" android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <ProgressBar android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:id="@+id/progressbar_default" />
        
    <ProgressBar android:layout_width="fill_parent"
        android:layout_height="wrap_content" style="?android:attr/progressBarStyleHorizontal"
        android:id="@+id/progressbar_Horizontal" android:max="100" />

</LinearLayout>

The first issue I see at a glance is that your webview is filling the parent linear layout, so you will never see the progressbar because the webview will have filled the screen.

I'd say start with working on your layout and see how things go from there.
