Option menu option not directing to another activity

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;
}

Android Actionbar Menu Item not Selecting

I have an android Activity with a bottom menu navigation bar, That navigates between three fragments and a single top menu item that should open a new activity, But the top menu ActionBar item is not responding to click events. Maybe there is something am missing? Or should I be handling the menu from within my fragments?
Here is my code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Set Network Connection Listener
setConnectionListener(this);
//check the network connectivity when activity is created
checkConnection();
BottomNavigationView bottomNavigation = (BottomNavigationView) findViewById(R.id.bottom_navigation);
bottomNavigation.setOnNavigationItemSelectedListener(this);
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.frame_layout, HomeFragment.newInstance());
transaction.commit();
// Used to select item programmatically
// bottomNavigation.getMenu().getItem(0).setChecked(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.top, menu);
// return super.onCreateOptionsMenu(menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Log.i(TAG, "Menu Clicked " + item.getItemId());
switch (item.getItemId()){
case R.id.tab_cart:
Intent intent = new Intent(this, CartActivity.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
My Menu top.xml res menu file
<?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"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.shopcentra.activities.MainActivity">
<item
android:id="#+id/tab_cart"
android:icon="#mipmap/cart"
android:title="#string/cart"
app:actionLayout="#layout/notification_layout"
app:showAsAction="always">
</item>
</menu>

I can't see where you've added a View.OnClickListener on the "tab_cart". If you have set one, please share that code as well otherwise, add an OnCLickListener on that view and see if the problem persists then as well.
EDIT: code to add OnClickListener on menu item:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuItem tabCartMenuItem = menu.findItem(R.id.tab_cart);
View notificationActionView = menuItem.getActionView();
notificationActionView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(tabCartMenuItem));
}
});
}
Try adding this code to your onCreateOptionsMenu() method.

Android not showing menu

I'm a new one in Android. I have some problems with showing menu. I don't see three dots in right corner in my screen. Please, help me to understand my mistake. THANK YOU A LOT!
Activity:
public class MainActivity extends AppCompatActivity {
private EditText numb1;
private EditText numb2;
private Button btn_sum;
private Button btn_extr;
private Button btn_mult;
private Button btn_div;
private TextView result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*some code*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.reset:
numb1.setText("");
numb2.setText("");
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(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">
<item android:id="#+id/reset"
android:title="#string/reset"
app:showAsAction="never"/>
<item android:id="#+id/exit"
android:title="#string/exit"
app:showAsAction="never"/>
</menu>

Menu Items are not showing on Action Bar
Check this answer
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option1"/>
<item
android:id="#+id/action_settings34"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option2"/>
<item
android:id="#+id/action_settings3"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option3"/>
</menu>

Use this code in your activity, but you should have action bar in it.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.your_menu, menu);
return true;
}

if you run your application on oldest version of samsung or other the three DOTS is not appear on ActionBar
so try to click on Option Key on mobile
The solution to appear Three DOTS
call this method in your application class' onCreate method
private void makeActionOverflowMenuShown() {
//devices with hardware menu button (e.g. Samsung Note) don't show action overflow menu
try {
ViewConfiguration config = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
} catch (Exception e) {
Log.d(TAG, e.getLocalizedMessage());
}
}

i am also new to android i guess u wrote onCreateOptionsMenu(Menu menu) inside on create
try this
public class MainActivity extends AppCompatActivity {
private EditText numb1;
private EditText numb2;
private Button btn_sum;
private Button btn_extr;
private Button btn_mult;
private Button btn_div;
private TextView result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*some code*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.reset:
numb1.setText("");
numb2.setText("");
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(item);
}
}

You have done the minor mistake while creating the option menu .you should call the onCreateOptionsMenu() and onOptionsItemSelected() method outside the onCreate(Bundle savedInstanceState) method. you may check the following example :
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.reset:
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(item);
} }

Help me to understand my mistake - Sure
The Main culprit is in your menu XML file app:showAsAction="never" this line replace this line with app:showAsAction="ifRoom"
here showAsAction is set to never means you tell that don't show my menu in action bar if you replace with "ifRoom" means you said show my all menu in action bar and if there is space for all my menus

Action bar share button not working after upload on playstore

App share button on action bar is not working after i upload the app update on the play store as it works on the testing devices and also works on emulator.. ?
thank you in advance .
Circled part is not working after uploading on play store
Activity:
public class RecommendetableActivity extends AppCompatActivity {
Button button;
Intent ShareIntent;
ShareActionProvider mShareActionProvider;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setContentView(R.layout.recommended_table);
ShareIntent = new Intent();
ShareIntent.setAction(Intent.ACTION_SEND);
ShareIntent.setType("text/plain");
ShareIntent.putExtra(Intent.EXTRA_TEXT, "https://play.google.com/store/apps/............app name ");
button = (Button)findViewById(R.id.close_button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
overridePendingTransition(R.anim.backfadein, R.anim.backfadeout);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.popup_menu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
// Get its ShareActionProvider
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
// Connect the dots: give the ShareActionProvider its Share Intent
if (mShareActionProvider != null) {
mShareActionProvider.setShareIntent(ShareIntent);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
overridePendingTransition(R.anim.backfadein, R.anim.backfadeout);
return true;
}
return false;
}
#Override
public void onBackPressed() {
finish();
overridePendingTransition(R.anim.backfadein, R.anim.backfadeout);
super.onBackPressed();
}
}
popup_menu.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">
<item
android:id="#+id/menu_item_share"
android:title=""
app:showAsAction="always"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
/>
</menu>

I had this issue as well once and after some digging inside the Logcat of Play store ready APK, I found the problem; it might apply to you as well.
The Issue was NoClassDefFoundError exception on ShareActionProvider !
Solution is to add this rule to your ProGuard file such as proguard-rules.pro and that's it!
-keep class android.support.v7.widget.ShareActionProvider { *; }

Why is onBackPressed() not being called?

I am attempting to override onBackPressed(). However it appears to not detect when I click the back button in the action bar.
I currently have this code:
#Override
public void onBackPressed() {
Log.i("DATA", "Hit onBackPressed()");
super.onBackPressed();
}
The log message never appears in the LogCat. I know that this log statement works because it is copied from another method with a different message that DOES display in the LogCat.
I have searched for answers, and I have tried using onKeyDown and detecting if it is the BACK button being clicked but I still have the same issue.
Information about the project:
Android Studio 0.9.3
Method is located in blank activity
target sdk 21
minimum sdk 15
testing device is a Samsung Galaxy 5 (not emulator)
Any help would be greatly appreciated!!
EDIT:
This is a copy of my working code (this is test code so the activity name is not descriptive):
public class MainActivity2 extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_activity2);
getActionBar().setDisplayHomeAsUpEnabled(true);//Displays the back button
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main_activity2, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
Log.i("DATA", "Hit Actionbar Back Button");
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
The message "Hit Actionbar Back Button" now appears in the LogCat.

onBackPressed() is invoked when user clicks on a hardware back button (or on the 'up' button in the navigation bar), not the button in the action bar. For this one you need to override onOptionsItemSelected() method. Example:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// click on 'up' button in the action bar, handle it here
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Please try this code,
public class MainActivity2 extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public void onBackPressed() {
// TODO Auto-generated method stub
super.onBackPressed();
Toast.makeText(getApplicationContext(), "back press is call", Toast.LENGTH_LONG).show();
}
}
