Of course, you can always set the gravity of the original text view. This allows you to not have to worry about formatting and padding.

For example

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Title");
builder.setMessage("Message");
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.show();

// Must call show() prior to fetching text view
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);

Awesome trick. But it doesn't work for 'title' of AlertDialog ! – Gaurav Arora Nov 01 '12 at 12:48
I've not tested, but I'm sure you could do a similar thing for the Title by doing android.R.id.title. This works great for the message though. – Joss Stuart Nov 05 '12 at 13:59
Do you think this has a better perfomance? I know that this is impossiible to get from the user, just curious. – Enrichman May 17 '13 at 13:56
This is also a great solution as I can set a separate view to my dialog and still be able to control the attributes of the TextView. A custom TextView forces me to use it as the dialog's view. – sturrockad Nov 06 '13 at 10:30

For those who get null as a result. Read the answer carefully. _Must call show() prior to fetching text view_ – Dominic Aug 20 '14 at 12:10

Just a little FYI if anybody come across this, **To change the text style of Positive,Negative and Neutral buttons the ids are `button1`,`button2` and `button3` respectively** – IronBlossom Feb 09 '15 at 10:56

Create your own TextView object and then supply it to popup builder as View:

AlertDialog.Builder popupBuilder = new AlertDialog.Builder(this);
TextView myMsg = new TextView(this);
myMsg.setText("Central");
myMsg.setGravity(Gravity.CENTER_HORIZONTAL);
popupBuilder.setView(myMsg);

You can control all other text parameters (style, color, size ...). To control margins you may programatically create LinearLayout, set LayoutParams, and then put TextView into it.

In case I want to add buttons or any other default components in order to get the default look of the dialog I need to do it by myself. I liked more Chase answer. – Alex K Jun 09 '12 at 12:14
I have to admit that I also like more the answer from Chase. This was the first approach that came to my mind, and I wanted to answer it quickly. – Zelimir Mar 25 '13 at 09:09

Building off of Chase's answer, here's how to also center the title. I think this is the easiest way. Why android doesn't center by default or make it a simple constructor param is beyond me.

AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("My Title");
builder.setMessage("My message");
builder.setPositiveButton("OK", listener);
AlertDialog dialog = builder.show();

// Must call show() prior to fetching views
TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);

TextView titleView = (TextView)dialog.findViewById(context.getResources().getIdentifier("alertTitle", "id", "android"));
if (titleView != null) {
    titleView.setGravity(Gravity.CENTER);
}

we can use as like.

public static void showAlert(Activity activity, String message) {
  TextView title = new TextView(activity);

  title.setText("Your Title Here");
  title.setPadding(10, 10, 10, 10);
  title.setGravity(Gravity.CENTER);
  title.setTextColor(Color.WHITE);
  title.setTextSize(20);

  AlertDialog.Builder builder = new AlertDialog.Builder(activity);
  builder.setCustomTitle(title);
  builder.setMessage(message);
  builder.setCancelable(false);
  builder.setNegativeButton("OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
      dialog.cancel();
    }
  });

  AlertDialog alert = builder.show();
  TextView messageText = (TextView)alert.findViewById(android.R.id.message);
  messageText.setGravity(Gravity.CENTER);
  messageText.setTextColor(Color.RED);
}

you can try this code

public void Info(){
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Info Aplication");
    builder.setIcon(R.drawable.info_adp);
    builder.setMessage("Jakarta Hospital");
    builder.setCancelable(false);
    builder.setPositiveButton("Exit", null);
    AlertDialog dialog = builder.show();
    TextView messageView = (TextView)dialog.findViewById(android.R.id.message);
    messageView.setGravity(Gravity.CENTER);
}

Post a description above your code, so others can understand what you did – Juan Cruz Soler Jun 15 '16 at 23:26

without using textview. worked for me.

styles.xml

<style name="CustomAlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
        <item name="android:gravity">center</item>
    </style>

Alertdialog

final AlertDialog builder = new AlertDialog.Builder(activity, 
R.style.CustomAlertDialog)
