In this tutorial we will learn about how to create menu in application with simple ways.
Type of Menu:-there are two type of menu in android
1. Option menu
2. Context menu
1) Options menu
Now we will learn to create option menu with simple step.
1.Now first Create a folder named menu inside your project res directory.Now let us add a new xml file named menu_item.xml file
2.add item in menu_item.xml.
<?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">
<!-- this is first for Search item-->
<item
android:id="@+id/action_search1"
android:title="Profile"
android:orderInCategory="100"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="ifRoom" />
<!-- this is use for Search item-->
<item
android:id="@+id/action_search"
android:icon="@android:drawable/ic_menu_search"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"
android:title="Search"/>
<!-- this is use for setting option-->
<item
android:id="@+id/action_settings"
android:title="@string/action_settings"
android:orderInCategory="100"
app:showAsAction="never" />
</menu>
3.Now we will implement the onCreateOptionsMenu() method in Activity class and inflate the menu items created in the menu_item.xml. We will also override method OnOptionsItemSelected for handle the events when user presses the menu option in android.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.home, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
if(id == R.id.action_search){
Toast.makeText(getApplicationContext(), "Search action is selected!" , Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
1.output screen for three type menu item .
menu item 1 : this is SearchView item and it's :showAsAction="always" it mean this is always show on ActionBar.
menu item2 : this is TextView item and it's showAsAction="ifRoom" it mean this is show in ActionBar if space available on ActionBar otherwise it will open with menu item list as show on image like other menu(three dot).
other menu : this is contain all other menu like howAsAction="never properties menu item as well as showAsAction="ifRoom" item if no space on ActionBar.
menu item2 : this is TextView item and it's showAsAction="ifRoom" it mean this is show in ActionBar if space available on ActionBar otherwise it will open with menu item list as show on image like other menu(three dot).
other menu : this is contain all other menu like howAsAction="never properties menu item as well as showAsAction="ifRoom" item if no space on ActionBar.
2) Context menu
Now we will talk about to create option menu with simple step.
Context Menu is also useful part of application.When we want to open menu in long press of any view class and subClass of android.Context Menu appears when user long press on a View like ListView, GridView etc.
You must to register each view whenever you want to associated with the context menu.
like this;-
registerForContextMenu(lv); // lv is a List View
Lets take a exampke.
package com.example.contextmenuapp;
import java.util.ArrayList;
import android.app.ListActivity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.MenuItem;
import android.view.View;
import android.view.ContextMenu.ContextMenuInfo;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.AdapterView.AdapterContextMenuInfo;
public class StudentActivity extends ListActivity
{
ListView lv;
ArrayList<String> list;
ArrayAdapter<String> adp;
@Override
protected void onCreate(Bundle savedInstanceState) {
lv = getListView();
list = new ArrayList<String>();
list.add("Dheeraj");
list.add("Manish");
list.add("Rohan");
list.add("Prakhar");
list.add("Pranav");
adp = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,list);
lv.setAdapter(adp);
registerForContextMenu(lv);
super.onCreate(savedInstanceState);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo)
{
menu.add(0,1,0,"Red");
menu.add(0,2,0,"Green");
menu.add(0,3,0,"Blue");
super.onCreateContextMenu(menu, v, menuInfo);
}
@Override
public boolean onContextItemSelected(MenuItem item)
{
int id = item.getItemId();
AdapterContextMenuInfo minf = (AdapterContextMenuInfo) item.getMenuInfo();
TextView tv = (TextView) minf.targetView;
switch(id)
{
case 1:
tv.setTextColor(Color.RED);
break;
case 2:
tv.setTextColor(Color.GREEN);
break;
case 3:
tv.setTextColor(Color.BLUE);
break;
}
return super.onContextItemSelected(item);
}
}
