10 The class ProgressDialog
The class ProgressDialog.Builder implements a builder, which allows to create dialogs, which can be used to indicate a running progress. Besides a circular progress bar such dialogs can contain a title, a message and up to three buttons.
For configuring the dialog's title, message and buttons the methods and theme attributes, which have already been discussed and are similar to those of the class MaterialDialog.Builder can be used. Furthermore, the following methods are provided by the class MaterialDialog.Builder:
| Setter methods | Description | Default value | Restrictions |
|---|---|---|---|
setProgressBarColor(int):Builder |
Sets the color of the dialog's progress bar. | R.attr.colorAccent |
Must be a valid color, not a resource ID. |
setProgressBarSize(int):Builder |
Sets the size of the dialog's progress bar in pixels. | R.dimen.circular_progress_bar_size_normal |
The size must be at least 1. |
setProgressBarThickness(int):Builder |
Sets the thickness of the dialog's progress bar in pixels. | R.dimen.circular_progress_bar_thickness_normal |
The thickness must be at least 1. |
setProgressBarPosition(ProgressBarPosition):Builder |
Sets the position of the dialog's progress bar in relative to the message. | ProgressBarPosition.LEFT |
The position may not be null. |
As an alternative to using the setter methods shown above, theme attributes, which are shown in the table below, can be used to change the appearance of the dialog.
