import android.content.res.Resources;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
import java.util.List;

public class Page1 extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ListView lv = (ListView) findViewById(R.id.list1);
        String[] ListItems = getResources().getStringArray(R.array.ListMenu);
        ArrayAdapter adapter = new ArrayAdapter<String>(this,
                R.layout.activity_page1, ListItems);
        lv.setAdapter(adapter);
        registerForContextMenu(lv);
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_page1, menu);
        return true;
    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v,
                                    ContextMenu.ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
        //getMenuInflater().inflate(R.menu.menu_page1, menu);
        if (v.getId() == R.id.list1) {
            AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
            menu.setHeaderTitle("Context Menu");
            String[] menuItems = {"Upload", "Watch"};
            for (int i = 0; i < menuItems.length; i++) {
                menu.add(Menu.NONE, i, i, menuItems[i]);
            }
        }

    }

**@Override public boolean onContextItemSelected(MenuItem item) { AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();

        int menuItemIndex = item.getItemId();
        String[] menuItems = getResources().getStringArray(R.array.ListMenu);
        String[] ListItems = getResources().getStringArray(R.array.ListMenu);
        String menuItemName = menuItems[menuItemIndex];
        String listItemName = ListItems[info.position];


            Toast.makeText(getApplicationContext(),"U have selected to " + menuItemName + " "  +  listItemName,Toast.LENGTH_SHORT).show();
        return true;

        }**
