Actionbar menu buttons not able to navigate to other Activities (Android)

Question

I'm using a menu for the actionbar, and here is my xml mainactivity.xml under menus:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id = "@+id/Viewmain"
        android:orderInCategory="200"
        app:showAsAction="always"
        android:title="VIEW"/>

    <item
        android:id = "@+id/Addmain"
        android:orderInCategory="205"
        app:showAsAction="always"
        android:title="ADD"/>


</menu>

Here is the code I used to navigate the buttons on the actionbar to other Activities in mainactivity.java:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);




   }


    public boolean onContextItemSelected (MenuItem item)
    {

        if (item.getItemId()==200)
        {
            Intent myintent = new Intent(this, ViewStats.class );
            startActivity(myintent);
            return  true;
        }
        else if (item.getItemId()==205)
        {
            Intent myaddintent = new Intent(this,Sales.class );
            startActivity(myaddintent);

        }

        return  super.onOptionsItemSelected(item);
    }


   public  boolean onCreateOptionsMenu(Menu menu)
   {
       super.onCreateOptionsMenu(menu);
       this.myMenu = menu;


       getMenuInflater().inflate(R.menu.main, menu);
       return  true;



   }

However when I click on the actionbar buttons "VIEW" & "ADD", no changes occur. What is wrong with my codes? Please help. (Note: No errors were shown on the stacktrace)

Answer 1

you have to implement following methods to options menu

for creating menu

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);///here add your menu layout
    return true;
}

for select menu item this method need to implemented

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.new_game:
            newGame();
            return true;
        case R.id.help:
            showHelp();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

don't add hard coded id comparison u can just add ur item id by R.id.yourid
