I am trying to disable programmatically a menu item if WebView class is not activated.
I tried this code:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
super.onPrepareOptionsMenu(menu);
MenuItem item = menu.findItem(R.id.itemRefresh);
if (WebViewFragment.viewContentWebView.isActivated()){
item.setVisible(true);
item.setEnabled(true);
} else
{
item.setVisible(true);
item.setEnabled(false);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.itemRefresh:
WebViewFragment.viewContentWebView.reload();
return true;
case R.id.itemAdd:
//oke im gonna write here
return true;
case R.id.itemHelp:
// ok ok i will
return true;
default:
return true;
}
}
In Eclipse I don't get any error msg but on real device App blocks itself.
I think I'm doing something wrong in IF-ELSE statement part.
Thank you.

When you are using Intent that time why need two different class with same body. What I suggest is In case body write a Intent for class B menu.. see whether work or not .
Go through the documentation of the Intent in Android and Also menu Android documentation you will find more information .
I have the following code in my app. There is a login button which works fine on my view. I've overridden the optionsmenu on my view and placed the login code inside a listener attached to the optionsmenu. When i press the optionsmenu login button nothing happens on the first click, but everything works fine on subsequent clicks. Why is this?
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.layout.menuentryoptionsmenu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.login:
item.setOnMenuItemClickListener(new OnMenuItemClickListener(){
#Override
public boolean onMenuItemClick(MenuItem item) {
// TODO Auto-generated method stub
Log.e(TAG, "login clicked from opts menu");
compId = "100";
String theUsername = userName.getText().toString();
thePassword = passwordPin.getText().toString();
String loginType = "1";
String[] params = new String[]{compId, theUsername, thePassword, loginType};
//validate user Asynchonously on background thread
AsyncValidateCarer avc = new AsyncValidateCarer();
avc.execute(params);
return true;
}});
return true;
case R.id.changeuser:
if(isAllowChangeUser.equalsIgnoreCase("false")){
item.setVisible(false);
}
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Remove the click listener.
Just put the whole login code after the case R.id.login:.
That's because onOptionsItemSelected is already the click, you don't have to create and set it again.
It would seem that the first time you click on the option menu item, you are only adding the OnMenuItemClickListener listener. The second time you click, you are triggering that listener.
Try removing the onMenuItemClickListener code and put the code in your onMenuItemClick function into the switch statement directly.
I'm trying to make my top action bar icon to allow users to go back to previous screen. I tried to implement these codes. But none are working. Can anyone please guide me on this. I know this looks simple, I'm new to android . Below are my codes.
Problem : When i tap on the icon button it just cleared my screen without going to the previous screen.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view_item);
checkInternetConnection();
getSupportActionBar().setDisplayHomeAsUpEnabled(true); //<--THIS
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case android.R.id.home:
Intent intent = new Intent(this, SingleViewActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_TASK_ON_HOME);
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
This is the way I do it:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; go home
Intent intent = new Intent(this, main.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
break;
}
return true;
}
In your ressources(res)
go to menu
and add
this make sur u have some button back for in your drawable
<?xml version="1.0" encoding="utf-8"?>
<item
android:id="#+id/back"
android:icon="#drawable/back1"
android:showAsAction="always|withText"
android:title="back"/>
now in your activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
break;
case R.id.back:
Intent in = new Intent(this, <classname which you want to go back>.class);
startActivity(in);
break;
}
return false;
}
you may try this code
<item
android:id="#+id/back"
android:icon="#drawable/btn_back"
android:showAsAction="always|withText"
android:title="#string/txt_back"/>
>
#Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
// TODO Auto-generated method stub
getSupportMenuInflater().inflate(R.menu.home, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
// TODO Auto-generated method stub
//return super.onOptionsItemSelected(item);
switch (item.getItemId())
{
case R.id.back:
back_action();
return true;
default:
break;
}
return true;

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

}
And my XML file is more_tab_menu.xml
<?xml version="1.0" encoding="utf-8"?>

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
Chenge in styles.xml the
