Dynamic UI API

Change native UI elements like the status bar or bottom bar colors dynamically from your web app.

WebViewGold allows you to dynamically customise the UI elements in your web app. These elements may consist of the status bar, bottom bar (iOS), navigation bar (Android) and pull to refresh (iOS). WebViewGold includes the following commands to dynamically customise these elements:

  • statusbarcolor://
    • The MASTER COMMAND to change the color of the status bar and any other relevant UI features automatically, such as the status bar text color, the bottom bar color (iOS), navigation bar color (Android), etc.
  • statusbartextcolor://
    • Allows you to manually change the text color of the status bar (iOS and Android).
  • bottombarcolor://
    • If a bottom bar (iOS) or navigation bar (Android) UI element exists, allows you to manually change its color.
  • hidebars://
    • Allows you to hide the background of the status bar, whos text remains on a transparent background.

Changing the color of the Status Bar (and other UI elements automatically):

This feature supports a color input in the following format:
  • RGB = {red, green, blue}
Where the values are integers between 0 (min) and 255 (max).

Use JavaScript to this kind of URL to change the color of the status bar:
<script>
// Example: red
window.location.href = "statusbarcolor://255,0,0";
</script>

When you change the status bar color, the status bar text will automatically change to a suitable color (white or black) depending on how dark the color is.
Optional UI features like Pull To Refresh (iOS), the Bottom Bar (iOS) and the Navigation Bar (Android) will also have their colors automatically adjusted.

Changing the color of the Status Bar text:

If you would like to manually choose the color of the status bar text, you can do so using this option.
This feature supports a text input for the following options:
  • "white"
  • "black"
Use JavaScript to this kind of URL to change the color of the status bar text:
<script>
// Example: white text
window.location.href = "statusbartextcolor://white";
// Example: black text
window.location.href = "statusbartextcolor://black";
</script>


Changing the color of the Bottom Bar:

This feature supports a color input in the following format:
  • RGB = {red, green, blue}
Where the values are integers between 0 (min) and 255 (max).

Use JavaScript to this kind of URL to change the color of the status bar:
<script>
// Example: red
window.location.href = "bottombarcolor://255,0,0";
</script>


Hiding the status bar

The hidebars functionality can either be on or off.
Note, the status bar text, such as the time and battery percentage remain visible to the user, but the background surrounding the text becomes transparent and the WebView expands to fill the room left.
Use JavaScript to change the visibility status of the bar:
<script>
// Example: hide the bars from view
window.location.href = "hidebars://on";
// Example: redisplay the bars after being hidden
window.location.href = "hidebars://off";
</script>
