How should Android dialog source be organized in an application?

My application contains many Dialog windows. It has gotten to the point that the source seems overwhelming. I am looking for opinions about the best way to segregate Dialog source. I am relatively new to Java, so I am assuming that I can put them in a separate class. However, the exact way to do this in Android alludes me. May someone point me in the right direction?

u can create dialogue by extending dialogue as follows 1. Create a Layout.xml for customDialog Create a new layout which contains the view. in this example i have used edittext and button. 

<?xml version="1.0" encoding="utf-8"?>


<EditText android:id="@+id/EditText01" android:layout_height="wrap_content" android:text="Enter your name" android:layout_width="250dip"></EditText>

<Button android:id="@+id/Button01" android:layout_width="wrap_content"
    android:layout_height="wrap_content" android:text="click"></Button>

  1. Create a Custom Dialog Class. a. Create a class extends the dialog class b. Create a Event Handler Interface as a member c. Use the custom layout in onCreate Method.

    public class MyCustomDialog extends Dialog {

public interface ReadyListener {
    public void ready(String name);
}

private String name;
private ReadyListener readyListener;
EditText etName;

public MyCustomDialog(Context context, String name, 
        ReadyListener readyListener) {
    super(context);
    this.name = name;
    this.readyListener = readyListener;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mycustomdialog);
    setTitle("Enter your Name ");
    Button buttonOK = (Button) findViewById(R.id.Button01);
    buttonOK.setOnClickListener(new OKListener());
    etName = (EditText) findViewById(R.id.EditText01);
}

private class OKListener implements android.view.View.OnClickListener {
    @Override
    public void onClick(View v) {
        readyListener.ready(String.valueOf(etName.getText()));
        MyCustomDialog.this.dismiss();
    }
}

    }

  2. Create a MainActivity and Implement the CustomDialog

    public class MainActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); MyCustomDialog myDialog = new MyCustomDialog(this, "", new OnReadyListener()); myDialog.show(); } private class OnReadyListener implements MyCustomDialog.ReadyListener { @Override public void ready(String name) { Toast.makeText(MainActivity.this, name, Toast.LENGTH_LONG).show(); } } }
