I want to create an intent that starts a new activity once a Menu Item is clicked, but I'm not sure how to do this. I've been reading through the android documentation, but my implementation isn't correct..and some guidance in the right direction would help. I've listed my code below and commented out my problem areas, I think I'm invoking the wrong method.
package com.jbsoft.SimpleFlashlight;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.*;
import android.view.MenuItem.OnMenuItemClickListener;
import android.widget.Button;
import android.widget.Toast;
public class SimpleFlashLightActivity extends Activity {
Button GreenButton; // Declare instances of buttons to use later
Button BlueButton;
private static final int OK_MENU_ITEM = Menu.FIRST;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
BlueButton = (Button) findViewById(R.id.bluebutton);
BlueButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//Display msg when user clicks Blue Button
showColorChangeMsg();
// Switch Activities on click
Intent blueintent = new Intent(SimpleFlashLightActivity.this,
BlueFlashLightActivity.class);
startActivity(blueintent);
}
});
//Install listener for second button
GreenButton = (Button) findViewById(R.id.greenbutton);
GreenButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Display msg when user clicks Green Button
showColorChangeMsg();
Intent greenintent = new Intent(SimpleFlashLightActivity.this,
GreenFlashLightActivty.class);
startActivity(greenintent);
}
});
;
/**************************************************************************************/
// Method Declarations // THIS IS WHERE I'M HAVING A PROBLEM
MenuItem AddColorButton = (MenuItem)findViewById(R.id.menu_insert);
boolean onOptionsItemSelected(AddColorButton) {
Intent intent = new Intent(SimpleFlashLightActivity.this,
BlueFlashLightActivity.class);
startActivity(intent);
return true;
;
};
/****************************************************************************************/
}
private void showColorChangeMsg()
{
Toast msgtoast = Toast.makeText(this.getBaseContext(), "SWITCH COLOR!",
Toast.LENGTH_LONG);
msgtoast.show();
}
private void showMsg(String msg) {
Toast toast = Toast.makeText(this, msg, Toast.LENGTH_LONG);
toast.show();
}
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater mi = getMenuInflater();
mi.inflate(R.menu.list_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case OK_MENU_ITEM:
showMsg("OK");
break;
}
return super.onOptionsItemSelected(item);
}
}
Add Following Code
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.new_item:
Intent i = new Intent(this,SecondActivity.class);
this.startActivity(i);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Menu items file looks like
res/menu/menu_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<item
android:id="#+id/settings"
android:title="Setting"
app:showAsAction="never" />
<item
android:id="#+id/my_activity"
android:title="My Activity"
app:showAsAction="always"
android:icon="#android:drawable/btn_radio"/>
</menu>
Java code looks like
src/MainActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.my_activity) {
Intent intent1 = new Intent(this,MyActivity.class);
this.startActivity(intent1);
return true;
}
if (id == R.id.settings) {
Toast.makeText(this, "Setting", Toast.LENGTH_LONG).show();
return true;
}
return super.onOptionsItemSelected(item);
}
And add following code to your AndroidManifest.xml file
<activity
android:name=".MyActivity"
android:label="#string/app_name" >
</activity>
I hope it will help you.
in addition to the options shown in your question, there is the possibility of implementing the action directly in your xml file from the menu, for example:
<item
android:id="#+id/OK_MENU_ITEM"
android:onClick="showMsgDirectMenuXml" />
And for your Java (Activity) file, you need to implement a public method with a single parameter of type MenuItem, for example:
private void showMsgDirectMenuXml(MenuItem item) {
Toast toast = Toast.makeText(this, "OK", Toast.LENGTH_LONG);
toast.show();
}
NOTE: This method will have behavior similar to the onOptionsItemSelected (MenuItem item)
This code is work for me
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
// add your action here that you want
return true;
}
else if (id==R.id.login)
{
// add your action here that you want
}
return super.onOptionsItemSelected(item);
}
This is how it looks like in Kotlin
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
<item
android:id="#+id/action_logout"
android:orderInCategory="101"
android:title="#string/sign_out"
app:showAsAction="never" />
Then in MainActivity
override fun onCreateOptionsMenu(menu: Menu): Boolean {
// Inflate the menu; this adds items to the action bar if it is present.
menuInflater.inflate(R.menu.main, menu)
return true
}
This is onOptionsItemSelected function
override fun onOptionsItemSelected(item: MenuItem): Boolean {
return when(item.itemId){
R.id.action_settings -> {
true
}
R.id.action_logout -> {
signOut()
true
}
else -> return super.onOptionsItemSelected(item)
}
}
For starting new activity
private fun signOut(){
MySharedPreferences.clearToken()
startSplashScreenActivity()
}
private fun startSplashScreenActivity(){
val intent = Intent(GrepToDo.applicationContext(), SplashScreenActivity::class.java)
startActivity(intent)
finish()
}
Replace Your onOptionsItemSelected as:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case OK_MENU_ITEM:
startActivity(new Intent(DashboardActivity.this, SettingActivity.class));
break;
// You can handle other cases Here.
default:
super.onOptionsItemSelected(item);
}
}
Here, I want to navigate from DashboardActivity to SettingActivity.

I want to set On Click Listener on menu item while i click on that menu then directly show dialog or any other activity, but how...?
Button btn1 = (Button) findViewById(R.id.button1);
btn1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
UpdateChecker.checkForDialog(Home.this);
}
});
This will Work:
In your menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/rate_us"
android:title="Rate us"/>
</menu>
In Main activity:
class MainActivity : AppCompatActivity(){
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
override fun onCreateOptionsMenu(menu: Menu?): Boolean {
menuInflater.inflate(R.menu.settings, menu);
return super.onCreateOptionsMenu(menu)
}
override fun onOptionsItemSelected(item: MenuItem): Boolean {
val id = item.itemId
when (id) {
R.id.rate_us -> {
///YOUR CODE
//
return true
}
else -> return
super.onOptionsItemSelected(item)
}
}
}
You create your menu options:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.your_menu, menu);
return true;
}
Then you use the following for click events on menu items:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.button1:
UpdateChecker.checkForDialog(Home.this);
return true;
case R.id.option_two:
//do something else
return true;
...
default:
return super.onOptionsItemSelected(item);
}
}
Then choose the dialog that suits your style from the developers website
e.g a standard alert dialog is:
new AlertDialog.Builder(context)
.setTitle("Your Title here")
.setMessage("Your message here")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do something
}
})
.setNegativeButton(android.R.string.no, null)
.setIcon(android.R.drawable.your_custom_drawbale)
.show();
in your menu xml add this
<item
android:onClick="clickME">
</item>
in your activity create a void
private void clickME(MenuItem menuItem){
}
At first you need to implement NavigationView.OnNavigationItemSelectedListener in your activity.
then, inside onCreate() method you need to initialize the navigation menu:
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
also you need to #overwrite onNavigationItemSelected(MenuItem item) like this:
#overwrite
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_item_1) {
//do whatever you want
} else if (id == R.id.nav_item_2) {
//do whatever you want
} else if (id == R.id.nav_item_3) {
//do whatever you want
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
bottomNavig.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
if (menuItem.getItemId() == R.id.wallet) {
menuItem.setChecked(true);
} else if (menuItem.getItemId() == R.id.home) {
menuItem.setChecked(true);
}
return false;
}
});
I want to navigate to another Activity when click on the option menu item 'settings' from the menu bar. Nothing actual happens.I have checked similar issues posted here, but i can understand why this is not working for option menu.
see the code below:
Can't go to a new activity from selected option from option menu
<item
android:id="#+id/mySettings"
android:title="#string/action_settings" />
<item
android:id="#+id/logout"
android:title="log out" />
code:
public class Dashboard extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.app_bar_menu,menu);
return super.onCreateOptionsMenu(menu);
}
public void openConfigure(){
Intent intent = new Intent(this,Configure.class);
this.startActivity(intent);
}
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
Use onOptionsItemSelected instead of onContextItemSelected cause you are using OptionMenu not ContextMenu.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
}
return super.onOptionsItemSelected(item);
}
to select an options menu item, you have to override onOptionItemSelected() :
try below code
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
}
return true;
}
I want to open a menu from a OnClickListener
without using the method onCreateOptionsMenu
My code:
toolbar.setNavigationIcon(R.drawable.week); //your icon
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v ) {
}
});
Thanks in advance!
I think you want to show/hide a menu item based on actions from users. To do that you must use onCreateOptionsMenu and whenever you want to show/hide the menu item, then call invalidateOptionsMenu (this method will call onCreateOptionsMenu again).
boolean mShowMenu = false;
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.your_menu, menu);
MenuItem item = menu.findItem(R.id.your_menu_item);
item.setVisible(showMenu);
return true;
}
And in your code, when you want to show menu item.
toolbar.setNavigationIcon(R.drawable.week); //your icon
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v ) {
mShowMenu = true;
invalidateOptionsMenu();
}
});
And give it a try.
You should need to create menu Interface in xml File Like this
<item
android:id="#+id/settings"
android:title="Setting"
app:showAsAction="never" />
<item
android:id="#+id/my_activity"
android:title="My Activity"
app:showAsAction="always"
android:icon="#android:drawable/btn_radio"/>
After that in the Java code of a particular class You need to create the code like this;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.my_activity) {
Intent intent1 = new Intent(this,MyActivity.class);
this.startActivity(intent1);
return true;
}
if (id == R.id.settings) {
Toast.makeText(this, "Setting", Toast.LENGTH_LONG).show();
return true;
}
return super.onOptionsItemSelected(item);
}
Hopefully this may resolve your problem
So I have a menu with 2 items set on it in res/menu/menu_item.xml. I want to add on onClick method to the Menu Item but where do I put the method? I have the menu_item set on 3 different activities but I want one universal method which is called by the onClick method in the menu_item.xml file.
res/menu/menu_item.xml code:
<?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/action_settings"
android:orderInCategory="100"
android:title="Household"
app:showAsAction="never"
android:onClick="myHousehold"/>
<item
android:id="#+id/profile"
android:orderInCategory="100"
android:title="About"
app:showAsAction="never"
android:onClick="aboutApp"/>
</menu>
This is the method which uses this XML to set the menu on each activity.
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return super.onCreateOptionsMenu(menu);
}
You actually don't need the onClick and should add a method like this to enter menu item activities:
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.action_settings:
{
// Here you can set your intent and start the activity
Intent intent1 = new Intent(this, myActivity.class);
this.startActivityForResult(intent1, MY_ACTIVITY_REQUEST);
return super.onOptionsItemSelected(item);
}
case R.id.profile:
{
// Here you can set your intent and start the activity
return super.onOptionsItemSelected(item);
}
default:
return super.onOptionsItemSelected(item);
}
}
You have to overrideonOptionsItemSelected method from your Activity class and check selected item and do your operation as per your needs.
Try this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_action_settings: {
// Do something
return true;
}
case R.id.profile: {
// Do something
return true;
}
}
return super.onOptionsItemSelected(item);
}
Create a common class like below:
//Utils.java
public class Utils{
Context mContext;
// constructor
public Utils(Context context){
this.mContext = context;
}
public String getUserName(){
return "test";
}
public void doSomething(){
// Do something
}
}
Use it from all activities:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_action_settings: {
Utils utils = new Utils(getApplicationContext());
String username = utils.getUserName();
return true;
}
case R.id.profile: {
// Do something
Utils utils = new Utils(getApplicationContext());
utils.doSomething();
return true;
}
}
return super.onOptionsItemSelected(item);
}
Hope this will help~
Here I tried to make option menu, but menu is not displaying on screen, so please guide me where am I doing mistake...
MenuTest.java
public class MenuTest extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.feeds:
break;
case R.id.friends:
break;
case R.id.about:
break;
}
return true;
}
}
And my XML file is more_tab_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/feeds"
android:title="Feeds"/>
<item
android:id="#+id/friends"
android:title="Friends"/>
<item
android:id="#+id/about"
android:title="About"/>
</menu>
Please guide me,
public class MenuTest extends Activity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
// return true so that the menu pop up is opened
return true;
}
}
and don't forget to press the menu button or icon on Emulator or device
please see :==
private int group1Id = 1;
int homeId = Menu.FIRST;
int profileId = Menu.FIRST +1;
int searchId = Menu.FIRST +2;
int dealsId = Menu.FIRST +3;
int helpId = Menu.FIRST +4;
int contactusId = Menu.FIRST +5;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(group1Id, homeId, homeId, "").setIcon(R.drawable.home_menu);
menu.add(group1Id, profileId, profileId, "").setIcon(R.drawable.profile_menu);
menu.add(group1Id, searchId, searchId, "").setIcon(R.drawable.search_menu);
menu.add(group1Id, dealsId, dealsId, "").setIcon(R.drawable.deals_menu);
menu.add(group1Id, helpId, helpId, "").setIcon(R.drawable.help_menu);
menu.add(group1Id, contactusId, contactusId, "").setIcon(R.drawable.contactus_menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1:
// write your code here
Toast msg = Toast.makeText(MainHomeScreen.this, "Menu 1", Toast.LENGTH_LONG);
msg.show();
return true;
case 2:
// write your code here
return true;
case 3:
// write your code here
return true;
case 4:
// write your code here
return true;
case 5:
// write your code here
return true;
case 6:
// write your code here
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Change your onCreateOptionsMenu method to return true. To quote the docs:
You must return true for the menu to be displayed; if you return false it will not be shown.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
new MenuInflater(this).inflate(R.menu.folderview_options, menu);
return (super.onCreateOptionsMenu(menu));
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.locationListRefreshLocations) {
Cursor temp = helper.getEmployee(active_employeeId);
String[] matches = new String[1];
if (temp.moveToFirst()) {
matches[0] = helper.getEmployerID(temp);
}
temp.close();
startRosterReceiveBackgroundTask(matches);
} else if (item.getItemId()==R.id.locationListPrefs) {
startActivity(new Intent(this, PreferencesUnlockScreen.class));
return true;
}
return super.onOptionsItemSelected(item);
}
you can create options menu like below:
Menu XML code:
<?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/Menu_AboutUs"
android:icon="#drawable/ic_about_us_over_black"
android:title="About US"/>
<item
android:id="#+id/Menu_LogOutMenu"
android:icon="#drawable/ic_arrow_forward_black"
android:title="Logout"/>
</menu>
How you can get the menu from MENU XML(Convert menu XML to java):
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_options_menu,menu);
return super.onCreateOptionsMenu(menu);
}
How to get Selected Item from Menu:
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()){
case R.id.Menu_AboutUs:
//About US
break;
case R.id.Menu_LogOutMenu:
//Do Logout
break;
}
return super.onOptionsItemSelected(item);
}
import android.app.Activity;
import android.os.Bundle;
import android.view.*;
import android.widget.*;
public class AndroidWalkthroughApp2 extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// show menu when menu button is pressed
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// display a message when a button was pressed
String message = "";
if (item.getItemId() == R.id.option1) {
message = "You selected option 1!";
}
else if (item.getItemId() == R.id.option2) {
message = "You selected option 2!";
}
else {
message = "Why would you select that!?";
}
// show message via toast
Toast toast = Toast.makeText(this, message, Toast.LENGTH_LONG);
toast.show();
return true;
}
}
Replace return super.onCreateOptionsMenu(menu); with return true; in your onCreateOptionsMenu method
This will help
And you should also have the onCreate method in your activity
The previous answers have covered the traditional menu used in android. Their is another option you can use if you are looking for an alternative
https://github.com/AnshulBansal/Android-Pulley-Menu
Pulley menu is an alternate to the traditional Menu which allows user to select any option for an activity intuitively. The menu is revealed by dragging the screen downwards and in that gesture user can also select any of the options.
Android UI programming is a little bit tricky. To enable the Options menu, in addition to the code you wrote, we also need to call setHasOptionsMenu(true) in your overriden method OnCreate().
Hope this will help you out.
IF your Device is running Android v.4.1.2 or before,
the menu is not displayed in the action-bar.
But it can be accessed through the Menu-(hardware)-Button.
Good Day
I was checked
And if You choose Empty Activity
You Don't have build in Menu functions
For Build in You must choose Basic Activity
In this way You Activity will run onCreateOptionsMenu
Or if You work in Empty Activity from start
