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. But 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 'com.github.tashilapathum:PleaseWait:0.6.5'

1. Intitialize with Activity or Fragment context and show.

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

2. Optionally set title and message

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

3. 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.setTitle("Please wait");
progressDialog.setMessage("Loading...");
progressDialog.setCancelable(false);
progressDialog.show();
