Google Glass Progress Bar

As of now, Google Glass GDK API has no Progress Bar view. So I extracted this from GlassHome.apk (from https://github.com/zhuowei/Xenologer).

Progress & indeterminate slider:

Message dialog with success sound:

Features

1. Progress bar, which is used by all native apps.
2. Supports default progress.
3. Supports indeterminate progress.
4. Supports MessageDialog with success sound found in Glass apps.

Setup

1. Add this library project to your project.
2. (optional) override progress bar height in your own res/values/dimens.xml --> <dimen name="slider_bar_height">12.0px</dimen>
3. (optional) override message dialog background dimming in res/values/dimens.xml --> <item type="dimen" name="background_dim_amount">0.75</item>

Use it!

For progress bar

1. Add progress bar view to your layout:

   <com.google.glass.widget.SliderView
       android:id="@+id/indeterm_slider"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:layout_alignParentBottom="true" />

2. Start it from activity:

    mIndeterm.startIndeterminate();
    mProgress.startProgress(10 * 1000); // progress which lasts 10 seconds

For Message Dialog

1. Use it in code:

  	MessageDialog localDialog = new MessageDialog.Builder(ctx)
				.setTemporaryIcon(R.drawable.ic_sync_50)
				.setTemporaryMessage(R.string.dlg_temp_message)
				.setTemporarySecondaryMessage(R.string.dlg_temp_secondary_message)
				.setIcon(R.drawable.ic_done_50)
				.setMessage(R.string.dlg_message)
				.setSecondaryMessage(R.string.dlg_secondary_message)
				.setDismissable(true)
				.setAutoHide(true)
				.setListener(new MessageDialog.SimpleListener() {
					public boolean onConfirmed() {
						Log.d(TAG, "onConfirm");
						Toast.makeText(ctx, "onConfirmed", Toast.LENGTH_LONG).show();
						return true;
					}
					public void onDismissed() {
						Log.d(TAG, "onDismissed");
						Toast.makeText(ctx, "onDismissed", Toast.LENGTH_LONG).show();
					}
					public void onDone() {
						Log.d(TAG, "onDone");
						Toast.makeText(ctx, "onDone", Toast.LENGTH_LONG).show();
					}
				}).build();
		localDialog.show();

Example

Look in testwithlibrary folder.

Disclaimer

Google Glass is in Explorer Stage. That's why I tried to find the answer to this SO question http://stackoverflow.com/questions/20237873/google-glass-gdk-progress-indicator and a workaround for this issue https://code.google.com/p/google-glass-api/issues/detail?id=271

This is just for educational purposes and should not be used in any production apps until Google releases something similar officially.

I hope, Google will publish a set of Google Glass Views in the future releases of GDK. We really need them! Especially that awesome progress bar!
