Content menu in Android

  Creating a Content Menu

Android has a unique mechanism called long press.

 When we click any button or image for long time a kind of menu appears that is called content menu.

Today i am doing a project related to this.

First of all i create a project called "Content_menu".

Then go to XML file.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

activity_main.xml

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

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" >

    <Button

        android:id="@+id/button1"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentLeft="true"

        android:layout_alignParentTop="true"

        android:layout_marginLeft="106dp"

        android:layout_marginTop="159dp"

        android:text="@string/button" />

</RelativeLayout>

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Adding a button in xml

Then i create a new xml file called contentmenu.xml

Note: Choose menu in Resource Type

Creating a new XML file

I write following codes in this xml:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

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

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

    <item android:id="@+id/item1" android:title="Item 1"/>

    <item android:id="@+id/item1" android:title="Item 1"/>

    </menu>

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

contentmenu.xml

Now i go to main java file.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

MainActivity.java

public class MainActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

Button b = (Button) findViewById(R.id.button1);

registerForContextMenu(b);

}

@Override

public void onCreateContextMenu(ContextMenu menu, View v,

ContextMenuInfo menuInfo) {

// TODO Auto-generated method stub

super.onCreateContextMenu(menu, v, menuInfo);

MenuInflater inflater = getMenuInflater();

inflater.inflate(R.menu.contextmenu, menu);

};

}

MainActivity.java

Now i run my project and it appears like this(video)
