I have found the solution. Perhaps this may help others in creating
an OPTIONS MENU in their application.
Here's the code:
package com.calculator;
import android.app.Activity;
import android.content.Intent;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class Calculator extends Activity {
private static final int MY_SETUP = 0; //
NOTE: ADD THESE TWO LINES FOR YOUR OPTIONS MENU
private static final int MY_ABOUT = 1;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
---- code of the project -----
// options menu
// Called only the first time the options menu is displayed.
// Create the menu entries.
// Menu adds items in the order shown.
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add("Setup") //
ADD LABEL
.setIcon(android.R.drawable.ic_menu_preferences); // ADD
ICON
menu.add("About") //
ADD LABEL
.setIcon(android.R.drawable.ic_menu_info_details); // ADD
ICON
return true;
}
// handle menu selected
public boolean onOptionsItemSelected(MenuItem item){
if (item.getTitle().equals("Setup")){
Intent intent = new Intent(this,
com.calculator.setup.class);
startActivityForResult(intent, MY_SETUP);
return true;
}
if (item.getTitle().equals("About")){
Intent intent = new Intent(this, com.calculator.about.class);
startActivityForResult(intent, MY_ABOUT);
return true;
}
return false;
}
}
----------------------------------------------------------
Create your layout files. I used dialogsetup.xml and
dialogabout.xml. I then created two class files called setup.java and
about.java
Here's part of the the setup.java file:
package com.calculator;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.EditText;
public class setup extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dialogsetup);
// put additional code in reference to the dialogsetup screen.
}
--------------------------------
You do the same with the about.java file. The dialogsetup.xml file
and the dialogabout.xml file contains the layout for that particular
option.
One thing that is most important once you have created these files,
and that is to add an activity to your manifest.xml file for each
activity that you created. This had two activities so the manifest
file has these entries added to it:
<activity android:name="setup"></activity>
<activity android:name="about"></activity>
If you don't add this, then you will get an error and be forced to
close your application.
Thanks again for all who has guided me in solving this problem.
