PleaseWait

PleaseWait is a lightweight library that can be used as a drop-in replacement for now-deprecated android.app.ProgressDialog. According to Google, the reason to deprecate the good old ProgressDialog is:

ProgressDialog is a modal dialog, which prevents the user from interacting with the app. Instead of using this class, you should use a progress indicator like ProgressBar, which can be embedded in your app's UI.

I understand the reasoning but it means we have to do some more work to prevent the user from doing something unexpected before the operation is finished. Come on, using a progress dialog is so much easier. So I made this library to use in my apps to avoid those deprecation warnings everywhere and to improve the look of the progress dialog. Also I wanted to learn the process of publishing a library.

How to use

1. Add the dependency to the app-level build.gradle.

implementation 'io.github.tashilapathum:please-wait:0.4.0'

2. Intitialize with Activity or Fragment context and show.

val progressDialog = PleaseWaitDialog(context = this)
progressDialog.show()

3. Optionally set title and message

progressDialog.setTitle("Please wait")
progressDialog.setMessage("Loading...")

4. Dismiss when the operation is complete

progressDialog.dismiss()

Additional options

• Choose progress style: CIRCULAR, LINEAR, BOTH or NONE. Default is CIRCULAR

progressDialog.setProgressStyle(PleaseWaitDialog.ProgressStyle.LINEAR)

• Set determinate or indeterminate mode. Default is true.

progressDialog.setIndeterminate(false) //apply to both progress bars
progressDialog.setIndeterminate(ProgressStyle.LINEAR, false) //apply to a specific progress bar

• Set progress. You can just set the progress and the progress bars will smoothly animate from indeterminate to determinate mode.

progressDialog.setProgress(20)

• Set a delay before showing to avoid flashing the progress dialog for short operations. The dialog won't be shown if you called dismiss() before the time has elapsed.

progressDialog.setShowDelay(2000)

• Set a delay before dismissing the dialog to show the dialog for a minimum amount of time.

progressDialog.setDismissDelay(3000)

• Set title and message by overriding resources on strings.xml. There's no title or message by default.

<string name="please_wait_dialog_default_title">Please wait</string>
<string name="please_wait_dialog_default_message">Loading…</string>

Java implementation

PleaseWaitDialog progressDialog = new PleaseWaitDialog(this);
progressDialog.seTitle("Please wait");
progressDialog.setMessage("Loading...");
progressDialog.setCancelable(false);
progressDialog.show();
