Answer 1

I know this thread is old but might help some people :D

TextView title = new TextView(this);
title.setText("Client details not saved!");
title.setPadding(10, 10, 10, 10);
title.setGravity(Gravity.CENTER);
// title.setTextColor(getResources().getColor(R.color.greenBG));
title.setTextSize(23);

TextView msg = new TextView(this);
msg.setText("You're going to lose all the information if you continue!");
msg.setPadding(10, 10, 10, 10);
msg.setGravity(Gravity.CENTER);
msg.setTextSize(18);

DialogInterface.OnClickListener onClick = new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {
        if (which == DialogInterface.BUTTON_POSITIVE) {
            finish();
        }
    }

};

Builder builder = new AlertDialog.Builder(this);
builder.setCustomTitle(title);
builder.setView(msg);
builder.setCancelable(true);
builder.setPositiveButton("Yes", onClick);
builder.setNegativeButton("No", onClick);

AlertDialog dialog = builder.create();
dialog.show();

Best way is to design Custom Dialog box.

view_dialog_box.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" 
android:background="#A9E2F3">

<TextView
    android:id="@+id/txtDiaTitle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Connection Alart"
    android:textColor="@color/Black"
    android:textStyle="bold"
    android:gravity="center"
    android:padding="5dp"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<View
    android:layout_width="match_parent"
    android:layout_height="1dip"
    android:background="#2E9AFE"
    android:layout_marginLeft="10dp"
    android:layout_marginRight="10dp"
    />

<TextView
    android:id="@+id/txtDiaMsg"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:padding="5dp"
    android:text="No Internet Connection"
    android:textColor="@color/Black" />

<Button
    android:id="@+id/btnOk"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="OK"
    android:textColor="@color/Black"
    android:textStyle="bold"
    android:padding="5dp" 
    android:layout_margin="5dp"
    android:background="@color/White"/>

Then it use in java file

final Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    dialog.setContentView(R.layout.view_dialog_box);

    // set the custom dialog components - text and button
    TextView text = (TextView) dialog.findViewById(R.id.txtDiaTitle);
    TextView image = (TextView) dialog.findViewById(R.id.txtDiaMsg);

    Button dialogButton = (Button) dialog.findViewById(R.id.btnOk);
    // if button is clicked, close the custom dialog
    dialogButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            dialog.dismiss();

        }
    }); 
    dialog.show();

Answer 3

try this

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("My Title");
builder.setMessage("your message");
builder.setPositiveButton("OK", null);
AlertDialog dialog = builder.show();
TextView messageText = (TextView)dialog.findViewById(android.R.id.message);
messageText.setGravity(Gravity.CENTER);
dialog.show();

Answer 4

Just use that method and your dialog title and message will appear at center:

public static void openDialog(Context context, String message) {

    TextView title = new TextView(context);
    // You Can Customise your Title here
    title.setText("Information Message");
    title.setBackgroundColor(Color.BLACK);
    title.setPadding(10, 15, 15, 10);
    title.setGravity(Gravity.CENTER);
    title.setTextColor(Color.WHITE);
    title.setTextSize(22);

    AlertDialog alertDialog = new AlertDialog.Builder(context).create();
    alertDialog.setCustomTitle(title);
    alertDialog.setMessage(message);

    alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    alertDialog.show();

    // You Can Customise your Message here
    TextView messageView = (TextView) alertDialog
            .findViewById(android.R.id.message);
    messageView.setGravity(Gravity.CENTER);

}

Answer 5

Have your TextView fill the parent and give it a center gravity.

<TextView ... android:layout_width="fill_parent" android:gravity="center" />

Answer 6

You can use your custom layout for alert dialog layout. To align default alert dialog layout message center you can do

        AlertDialog alertDialog;
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setMessage("hello world");
        alertDialog = builder.show();
        TextView messageText = (TextView) alertDialog.findViewById(android.R.id.message);
        messageText.setGravity(Gravity.CENTER);

Be careful, if you set messageText with findViewById before you call builder.show() you'll get a null pointer exception.
