ProgressDialog is deprecated.What is the alternate one to use?

Question

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:

<ProgressBar
        android:id="@+id/progressbar"
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:indeterminate="true"
        android:max="100"
        android:backgroundTint="@color/white"
        android:layout_below="@+id/framelauout"
        android:indeterminateTint="#1a09d6"
        android:layout_marginTop="-7dp"/>

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:

For more details:
1. Reference one
2. Reference Two

you can use AlertDialog as ProgressDialog refer below code for the ProgressDialog. This function you need to call whenever you show a progress dialog.

Code:

    public void setProgressDialog() {

    int llPadding = 30;
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.HORIZONTAL);
    ll.setPadding(llPadding, llPadding, llPadding, llPadding);
    ll.setGravity(Gravity.CENTER);
    LinearLayout.LayoutParams llParam = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.WRAP_CONTENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    ll.setLayoutParams(llParam);

    ProgressBar progressBar = new ProgressBar(this);
    progressBar.setIndeterminate(true);
    progressBar.setPadding(0, 0, llPadding, 0);
    progressBar.setLayoutParams(llParam);

    llParam = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT);
    llParam.gravity = Gravity.CENTER;
    TextView tvText = new TextView(this);
    tvText.setText("Loading ...");
    tvText.setTextColor(Color.parseColor("#000000"));
    tvText.setTextSize(20);
    tvText.setLayoutParams(llParam);

    ll.addView(progressBar);
    ll.addView(tvText);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setCancelable(true);
    builder.setView(ll);

    AlertDialog dialog = builder.create();
    dialog.show();
    Window window = dialog.getWindow();
    if (window != null) {
        WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
        layoutParams.copyFrom(dialog.getWindow().getAttributes());
        layoutParams.width = LinearLayout.LayoutParams.WRAP_CONTENT;
        layoutParams.height = LinearLayout.LayoutParams.WRAP_CONTENT;
        dialog.getWindow().setAttributes(layoutParams);
    }
}

Output:

You can simply design an xml interface for your progressbar and pass it as a view to a AlertDialog, then show or dismiss the dialog anytime you want.

progress.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:padding="13dp"
    android:layout_centerHorizontal="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ProgressBar
        android:id="@+id/loader"
        android:layout_marginEnd="5dp"
        android:layout_width="45dp"
        android:layout_height="45dp" />
    <TextView
        android:layout_width="wrap_content"
        android:text="Loading..."
        android:textAppearance="?android:textAppearanceSmall"
        android:layout_gravity="center_vertical"
        android:id="@+id/loading_msg"
        android:layout_toEndOf="@+id/loader"
        android:layout_height="wrap_content" />

</LinearLayout>

The code code that displays the progress dialog. Just copy this code and paste it your fragment.

Dialog dialog;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setView(R.layout.progress);
        // This should be called once in your Fragment's onViewCreated() or in Activity onCreate() method to avoid dialog duplicates.
        dialog = builder.create();
    }
    
//   This method is used to control the progress dialog.
      private void setDialog(boolean show){
               if (show)dialog.show();
                    else dialog.dismiss();
           }

Then just call the method whenever you want to show the progressdialog and pass true as an argument to show it or false to dismiss the dialog.

This class was deprecated in API level 26. 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. Alternatively, you can use a notification to inform the user of the task's progress. link

It's deprecated at Android O because of Google new UI standard

ProgressBar is very simple and easy to use, i am intending to make this same as simple progress dialog. first step is that you can make xml layout of the dialog that you want to show, let say we name this layout

layout_loading_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:padding="20dp">
    <ProgressBar
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="4"
        android:gravity="center"
        android:text="Please wait! This may take a moment." />
</LinearLayout>

next step is create AlertDialog which will show this layout with ProgressBar

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setCancelable(false); // if you want user to wait for some process to finish,
builder.setView(R.layout.layout_loading_dialog);
AlertDialog dialog = builder.create();

now all that is left is to show and hide this dialog in our click events like this

dialog.show(); // to show this dialog
dialog.dismiss(); // to hide this dialog

and thats it, it should work, as you can see it is farely simple and easy to implement ProgressBar instead of ProgressDialog. now you can show/dismiss this dialog box in either Handler or ASyncTask, its up to your need

Yes, ProgressDialog is deprecated but Dialog isn't.

You can inflate your own XML file ( containing a progress bar and a loading text) into your dialog object and then display or hide it using the show() and dismiss() functions. Here is an example (Kotlin):

ProgressDialog class:

class ProgressDialog {
companion object {
    fun progressDialog(context: Context): Dialog{
        val dialog = Dialog(context)
        val inflate = LayoutInflater.from(context).inflate(R.layout.progress_dialog, null)
        dialog.setContentView(inflate)
        dialog.setCancelable(false)
        dialog.window!!.setBackgroundDrawable(
                ColorDrawable(Color.TRANSPARENT))
        return dialog
    }
  }
}

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
android:background="#fff"
android:padding="13dp"
android:layout_height="wrap_content">
<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyle"
    android:layout_width="100dp"
    android:layout_margin="7dp"
    android:layout_height="100dp"/>
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_margin="7dp"
    android:layout_toEndOf="@+id/progressBar"
    android:text="Loading..." />
</RelativeLayout>

In your code: Just do var dialog = ProgressDialog.progressDialog(context)

To show: dialog.show()

To hide: dialog.dismiss()

Well if you really wants to go against their will, still you can use Sweet Alert Dialog or create one on your own.

progress_dialog_layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TableRow
        android:layout_centerInParent="true"
        android:layout_width="match_parent"
        android:layout_height="64dp" >

        <ProgressBar
            android:id="@+id/progressBar2"
            style="?android:attr/progressBarStyle"
            android:layout_width="wrap_content"
            android:layout_height="match_parent" />

        <TextView
            android:gravity="center|left"
            android:id="@+id/textView9"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:textColor="@color/black"
            android:textSize="18sp"
            android:text="Downloading data. Please wait.." />
    </TableRow>
</RelativeLayout>

Java code:

AlertDialog b;
AlertDialog.Builder dialogBuilder;

public void ShowProgressDialog() {
dialogBuilder = new AlertDialog.Builder(DataDownloadActivity.this);
LayoutInflater inflater = (LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE );
            View dialogView = inflater.inflate(R.layout.progress_dialog_layout, null);
            dialogBuilder.setView(dialogView);
            dialogBuilder.setCancelable(false);
            b = dialogBuilder.create();
            b.show();
        }

        public void HideProgressDialog(){

            b.dismiss();
        }
