The document discusses different types of dialog boxes in Android - ProgressDialog, AlertDialog, and custom dialog boxes. It provides code samples and explanations for creating and customizing ProgressDialogs with features like setting titles, messages, progress styles (horizontal or spinner), and dismissing. It also covers creating AlertDialogs with options to set titles, icons, messages, buttons and listeners. Finally, it demonstrates how to create a custom dialog box by designing a layout XML file and inflating it into a Dialog to add custom views, buttons and functionality.

2. ProgressDialog progressDialog;
• ProgressDialog progressDialog;
• //In OnCreate Method
• progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Loading..."); // Setting
• Message progressDialog.setTitle("ProgressDialog"); // Setting
Title
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNE
R); // Progress Dialog Style Spinner progressDialog.show(); //
• Display Progress Dialog progressDialog.setCancelable(false);
new Thread(new Runnable() {
• public void run() {
• try {

3. • Thread.sleep(10000);
• }
• catch (Exception e) {
• e.printStackTrace();
• }
• progressDialog.dismiss();
• }
• }).start();

4. Horizontal Progress Dialog
• progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMax(100);
• // Progress Dialog Max Value
progressDialog.setMessage("Loading..."); // Setting Message
progressDialog.setTitle("ProgressDialog"); // Setting Title
• progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZON
TAL); // Progress Dialog Style Horizontal
• progressDialog.show(); // Display Progress Dialog
progressDialog.setCancelable(false);
• new Thread(new Runnable() {
• @Override public void run() {
• try {
• while (progressDialog.getProgress() <= progressDialog.getMax())
{

5. • Thread.sleep(200);
• handle.sendMessage(handle.obtainMessage());
• if (progressDialog.getProgress() == progressDialog.getMax()) {
• progressDialog.dismiss();
• }
• }
• } catch (Exception e) {
• e.printStackTrace();
• } } }).start();

6. Methods
1. setTitle(CharSequence title) – This component is used to set the
title of the progress dialog.
// Setting Title progressDialog.setTitle("ProgressDialog");
2. setMessage(CharSequence message) – This component displays
the required message in the progress dialog.
// Setting Message progressDialog.setMessage("Loading...");
3. setProgressStyle(ProgressDialog.STYLE_HORIZONTAL) – This is
used for setting the horizontal style of the progress dialog.
// Progress Dialog Style Horizontal
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
4. setProgressStyle(ProgressDialog.STYLE_SPINNER) – This is used
for setting the spinner style of the progress dialog.
// Progress Dialog Style Spinner
progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);

7. •
5. setMax(int max) – This method sets the maximum value of the progress dialog.
• // Progress Dialog Max Value progressDialog.setMax(100);
• 6. getMax() – This method return the maximum value of the progress dialog,
basically this method is used while applying condition over the progress dialog.
• // Fetching max value progressDialog.getMax();
• 7. getProgess() – This returns current progress of the progress dialog in numeric.
• // Fetching current progress progressDialog.getProgress();
• 8. incrementProgressBy(int diff) – This method increments the progress dialog
value with the defined value.
• // Incremented By Value 2 progressDialog.incrementProgressBy(2);
• 9. setCancelable(boolean cancelable) – This method has boolean value i.e
true/false. If set to false it allows to cancel the dialog box by clicking on area outside
the dialog default it is true if method is not used.
• // Cannot Cancel Progress Dialog progressDialog.setCancelable(false);
• 10. dismiss() – This method dismiss the progressdialog.
• //Dismiss the dialog progressDialog.dismiss();

8. AlertDialog

• // Setting Alert Dialog Message
• alertDialogBuilder.setMessage(“Do you want to continue");
alertDialogBuilder.setCancelable(false);
• alertDialogBuilder.setPositiveButton("Yes", new
DialogInterface.OnClickListener() {
• @Override public void onClick(DialogInterface arg0, int arg1) {
• finish(); } });
• alertDialogBuilder.setNegativeButton("No", new
DialogInterface.OnClickListener() { @Override public void
onClick(DialogInterface dialog, int which)
{ Toast.makeText(MainActivity.this,"You
Continued",Toast.LENGTH_SHORT).show(); } });

9. • alertDialogBuilder.setNeutralButton("Cancel",
new DialogInterface.OnClickListener() {
• @Override public void onClick(DialogInterface
dialog, int which)
{ Toast.makeText(getApplicationContext(),“You
have canceled the
choice",Toast.LENGTH_SHORT).show(); } });
• AlertDialog alertDialog =
alertDialogBuilder.create(); alertDialog.show();

set the title of the alert dialog. It is optional component.

listener) – This component add negative button and further with this user confirm
he doesn’t want the alert dialog question to happen.
• alertDialogBuilder.setNegativeButton("No", new DialogInterface.OnClickListener()
{ @Override public void onClick(DialogInterface dialog, int which)
{ Toast.makeText(MainActivity.this,"You clicked over
No",Toast.LENGTH_SHORT).show(); } });
• 7. setNeutralButton(CharSequence text, DialogInterface.OnClickListener
listener) – This component simply add a new button and on this button developer
can set any other onclick functionality like cancel button on alert dialog.
• alertDialogBuilder.setNeutralButton("Cancel", new DialogInterface.OnClickListener()
{ @Override public void onClick(DialogInterface dialog, int which)
{ Toast.makeText(getApplicationContext(),"You clicked on
Cancel",Toast.LENGTH_SHORT).show(); } });

12. Custom Alert
• To Make Custom Alert,You have design a
layout that will be inflatedto
AlertDialogBuilder

13. Customalert.xml
• <?xml version="1.0" encoding="utf-8"?>
• <RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"> <
• TextView android:text="@string/alert"
android:layout_width="wrap_content"
android:layout_height="wrap_content" android:id="@+id/text"
android:textStyle="normal|bold" android:textSize="18sp"
android:layout_alignParentTop="true"
android:layout_toRightOf="@+id/image"
android:layout_toEndOf="@+id/image" android:layout_marginLeft="21dp"
android:layout_marginStart="21dp" android:layout_marginTop="12dp" />
<

14. • ImageButton android:layout_width="35dp"
android:layout_height="35dp" app:srcCompat="@drawable/stop"
android:id="@+id/image" android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
tools:ignore="ContentDescription,RtlHardcoded" /> <
• Button android:id="@+id/dialogButtonOK"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:text="@string/dismiss"
android:layout_marginTop="23dp" android:paddingRight="5dp"
android:layout_below="@+id/image"
android:layout_alignLeft="@+id/image"
android:layout_alignStart="@+id/image" android:textSize="18sp"
style="@style/Widget.AppCompat.Button.Colored“ />
</RelativeLayout>

15. Setting View
• final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom); Button
dialogButton = (Button)
dialog.findViewById(R.id.dialogButtonOK); // if
button is clicked, close the custom dialog
dialogButton.setOnClickListener(new
View.OnClickListener() { @Override public void
onClick(View v) { dialog.dismiss();
Toast.makeText(getApplicationContext(),"Dismiss
ed..!!",Toast.LENGTH_SHORT).show(); } });
dialog.show();
