Set Title to Android AlertDialog

To set a title to an Android AlertDialog we will have to make use of setTitle(String text) method. Lets see an example,

MainActivity.java

public class MainActivity extends ActionBarActivity {

  private  Toolbar toolbar;
    private Button myButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);


        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

        //Setting title to AlertDialog
        builder.setTitle("This is the Title!");
      

        builder.setMessage("Some message goes in here!");



        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {

            }
        });

        AlertDialog alertDialog = builder.create();
        alertDialog.show();
    }
}
