I have come across to see that ProgressDialog is now deprecated. What would be alternate one to use in place of that apart from ProgressBar.
I am
Yes, in API level 26 it's deprecated. Instead, you can use progressBar.
To create it programmatically:
First get a reference to the root layout
RelativeLayout layout = findViewById(R.id.display); //specify here Root layout Id
or
RelativeLayout layout = findViewById(this);
Then add the progress bar
progressBar = new ProgressBar(youractivity.this, null, android.R.attr.progressBarStyleLarge);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(100, 100);
params.addRule(RelativeLayout.CENTER_IN_PARENT);
layout.addView(progressBar, params);
To show the progress bar
progressBar.setVisibility(View.VISIBLE);
To hide the progress bar
progressBar.setVisibility(View.GONE);
To disable the user interaction you just need to add the following code
getWindow().setFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE,
WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
To get user interaction back you just need to add the following code
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE);
Just for future reference, change the android.R.attr.progressBarStyleSmall to android.R.attr.progressBarStyleHorizontal.
The code below only works above API level 21
progressBar.setProgressTintList(ColorStateList.valueOf(Color.RED));
To create it via xml:
In your activity
progressBar = (ProgressBar) findViewById(R.id.progressbar);
Showing/hiding the progress bar is the same
progressBar.setVisibility(View.VISIBLE); // To show the ProgressBar
progressBar.setVisibility(View.INVISIBLE); // To hide the ProgressBar
Here is a sample image of what it would look like:
