I am trying to change the text colour and font of title "Enter Details" which you can see in below snapshot but was not able to make it. Please help me to solve this problem.

**Code:-**

```
public class MainActivity extends Activity {
Button cust;
Dialog custom;
EditText Fname;
EditText Lname;
TextView txt;
Button savebtn;
Button canbtn;
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        cust = (Button)findViewById(R.id.cusdia);
        txt = (TextView)findViewById(R.id.txt);
        cust.setOnClickListener(new View.OnClickListener()
        {
            String fname,lname;
            @Override
            public void onClick(View view) {
                // TODO Auto-generated method stub
                custom = new Dialog(MainActivity.this);
                custom.setContentView(R.layout.dialog);

                Fname = (EditText)custom.findViewById(R.id.fname);
                Lname = (EditText)custom.findViewById(R.id.lname);
                savebtn = (Button)custom.findViewById(R.id.savebtn);
                canbtn = (Button)custom.findViewById(R.id.canbtn);
                custom.setTitle("Enter Details");

                savebtn.setOnClickListener(new View.OnClickListener() 
                {

                    @Override
                    public void onClick(View view) {
                        // TODO Auto-generated method stub
                        fname = Fname.getText().toString();
                        lname = Lname.getText().toString();

                        txt.setText("Your Name is "+fname +lname);
                        custom.dismiss();
                    }

                });

```
