Android Context Menu Example

Context Menu will open when we long press on any widget. Here, i will register to Linear Layout with context menu and when we long press on layout than context menu will pop-up.
Just open your main XML file and paste below code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/ll"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

</LinearLayout>


Now open your Java file and paste below code:

package sel.listG; //package name

import android.os.Bundle;

import android.view.ContextMenu;

import android.view.ContextMenu.ContextMenuInfo;

import android.view.MenuItem;

import android.view.View;

import android.widget.LinearLayout;

import android.app.Activity;

import android.graphics.Color;

public class MainActivity extends Activity  {

      LinearLayout ll;

      @Override

      protected void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);

            setContentView(R.layout.activity_main);

            ll=(LinearLayout)findViewById(R.id.ll);

            registerForContextMenu(ll);

                 

           

      }

//create context menu

      public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo info)

      {

            super.onCreateContextMenu(menu, v, info);

            menu.setHeaderTitle("Change Color");

            menu.setHeaderIcon(R.drawable.icon);

            menu.add(0, v.getId(),0, "RED");

            menu.add(0, v.getId(),1, "GREEN");

         

      }

      

//perform action on selected item

      public boolean onContextItemSelected(MenuItem item)

      {

            if(item.getTitle()=="RED")

            {

                  ll.setBackgroundColor(Color.RED);

            }

            else if(item.getTitle()=="GREEN")

            {

                  ll.setBackgroundColor(Color.GREEN);

            }

            else

            {

                  return false;

            }

            return true;

      }
