I had a menu in my app and it works correctly, now I add a TabLayout and the menu options does not respond to user click now no more.
Here is my activity_main.xml code:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include layout="#layout/toolbar"/>
<android.support.design.widget.TabLayout
android:id="#+id/tab"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill">
</android.support.design.widget.TabLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewPaper"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
My Activity onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
preferences = PreferenceManager.getDefaultSharedPreferences(this);
itemAdapter = new ClientAdapter(this, null);
tab = (TabLayout)findViewById(R.id.tab);
paper = (ViewPager)findViewById(R.id.viewPaper);
paperAdapter = new ViewPaperAdapter(getSupportFragmentManager());
HomeFragment homeFragment = new HomeFragment();
DoneFragment doneFragment = new DoneFragment();
paperAdapter.addFrament(homeFragment, "Home");
paperAdapter.addFrament(doneFragment, "Done");
paper.setAdapter(paperAdapter);
tab.setupWithViewPager(paper);
}
onCreateOptionMenu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem menuItem = menu.findItem(R.id.action_search);
searchView = (SearchView)MenuItemCompat.getActionView(menuItem);
searchView.setOnQueryTextListener(this);
return super.onCreateOptionsMenu(menu);
}
And onOptionItemSelected method:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.refresh:
//Check the internet connection
if(Util.isConnected(this)){
// showProgress();
//Check if there is not pending item
sincronize(this);
dbManager.borrar();
new HomeFragment().getTarjetas();
}else{
Toast.makeText(this, "No hay conexion a internet.", Toast.LENGTH_LONG).show();
}
break;
}
return super.onOptionsItemSelected(item);
}
The menu.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="developer.technologies.agilisa.acardmobile.MainActivity">
<item
android:id="#+id/action_search"

android:orderInCategory="100"
android:title="#string/Search"
app:showAsAction="always|collapseActionView"
android:elevation="8dp"
app:actionViewClass="android.support.v7.widget.SearchView"/>
<item
android:id="#+id/refresh"
android:title="#string/refresh"
android:icon="#drawable/refresh"

app:showAsAction="always|collapseActionView"/>
<item
android:id="#+id/cerrar"
android:orderInCategory="10"
app:showAsAction="never"
android:title="#string/cerrar_session"/>
Can some one help me to solve that?
Try this changes:
Change Your Root layout To LinearLayout or Coordinator Layout-- As framelayout sometimes consume the click event of items under it.
1.in onCreateOptionsMenu()
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//Your code
return true;
}
2.And in onOptionsItemSelected() add return true
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.refresh:
// your code
return true; //add this
default:
return super.onOptionsItemSelected(item);
}
}

mOnNavigationItemSelectedListener is null thats why you are getting error.You are initializing outside on oncreate method.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//move `mOnNavigationItemSelectedListener` code here .
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener

I have a switch in my app toolbar to provide an option to the user to change the language.
When I am using the switch, the onCheckedChanged method is not working.
Further, it looks to me that onOptionsItemSelected is also not being hit as I don't see any log message on the screen.
Please note that the app is not crashing when I use the switch.
The clicks on options present inside the overflow menu are working properly. I am getting the log in those cases.
Switch aSwitch;
RelativeLayout langSwitch;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
context = this;
// Removed non relevant code here.
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
Log.d("tag_id",String.valueOf(id));
langSwitch = findViewById(R.id.app_bar_switch);
aSwitch = langSwitch.findViewById(R.id.langSwitch);
aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (!b){
//Language1 code
Toast.makeText(context,"Language1 Selected",Toast.LENGTH_SHORT).show();
}else{
//Language2 code
Toast.makeText(context,"Language2 Selected",Toast.LENGTH_SHORT).show();
}
}
});
if (id == R.id.action_settings) {
return true;
}
if (id == R.id.savedPost){
Intent intent = new Intent(this,SavedPost.class);
startActivity(intent);
}
return super.onOptionsItemSelected(item);
}
Below is my 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="com.app_name.android.app_name.MainActivity">

app:showAsAction="never" />
<item
android:id="#+id/savedPost"
android:checkable="false"
android:orderInCategory="4"
android:title="#string/saved_post" />
</menu>
This is my layout file for switch item.
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Switch
android:id="#+id/langSwitch"

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:textOff="#string/switch_text_off"
android:textOn="#string/switch_text_on"
android:focusable="true"
android:clickable="true"/>
</RelativeLayout>
Additional information.
If I create another menu item (code below) with showAsAction 'always' and click on this once, now when I use the switch the Toast message comes. I am clueless here as to why is it not happening for the first time. Also, how do I make it work without this menu item.
<item
android:id="#+id/english"
android:orderInCategory="3"
android:title="#string/switch_text_on"
app:showAsAction="always" />
To inflate an external layout over ActionBar that seems to first creating a view that holds your ChildView for your layout
like Example
RelativeLayout item = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, null);
item.addView(child);
Try this in your code
Switch aSwitch;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
View sw = menu.findItem(R.id.app_bar_switch).getActionView();
aSwitch = (Switch) sw.findViewById(R.id.langSwitch);
aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (!b){
//Language1 code
Toast.makeText(context,"Language1 Selected",Toast.LENGTH_SHORT).show();
}else{
//Language2 code
Toast.makeText(context,"Language2 Selected",Toast.LENGTH_SHORT).show();
}
}
});
return true;
}
Try
(compoundButton.isChecked())
In boolean
Or
just try another version of setonCheckedChangedListner
Example:
aSwitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){#Override public void onCheckedChanged(CompoundButton compoundButton, boolean b) { if (!compoundButton.isSelected()) { Log.i("Yeah" , "Is Not Selected"); invertLock(-1); } else { if (Utilities.isLockEnabled(context)) { Log.i("Yeah" , "Is Locked"); Utilities.showLockEnabled(context); } else { Log.i("Yeah" , "Is Not Locked"); invertLock(1); } } }
I have this menu layout "navigation_menu.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="#string/item1"/>
<item

<item

My main activity layout "activity_main.xml" is this:
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
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"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity">
<android.support.design.widget.NavigationView
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="#menu/navigation_menu"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
And this is the Java code of the main activity where I initialize the drawer:
private DrawerLayout drawer_layout;
private ActionBarDrawerToggle toggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
// ...
drawer_layout = (DrawerLayout)findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(this, drawer_layout, R
.string.open_drawer, R.string.close_drawer);
drawer_layout.addDrawerListener(toggle);
toggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// ...
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (toggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
The drawer opens and closes correctly, but I don't know how to do something when an item is clicked, for example showing a log.
Does anyone know?
Thanks
Use onNavigationItemSelected() method to handle Navigation Drawer Item Click. See Below Code.
private NavigationView mNavigationView;
#Override
protected void onCreate(Bundle savedInstanceState)
{
// ...
mNavigationView = (NavigationView) findViewById(R.id.nav_view);
mNavigationView.setNavigationItemSelectedListener(this);// you need to set Listener.
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
// mDrawer.closeDrawer(GravityCompat.START);
switch (item.getItemId()) {
case R.id.item1: {
}
break;
case R.id.item2: {
}
break;
case R.id.item3: {
}
break;
}
return true;
}

Could someone help?
I fixed error by changing namespace in menu_main.xml from app to my own myapp and it fixed automaticly by pressing "Alt+Enter".

I faced the same problem. Solution is Simple.
Always check imports when doing alt+enter.
I did alt+enter and android.widget.SearchView got imported, whereas my implementation expected android.support.v7.widget.SearchView
Now my mainActivity.xml file like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/tool_bar" />
<FrameLayout android:id="#+id/tab_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<include layout="#layout/bottom_bar" />
</LinearLayout>
This page has four tabs on the bottom,each tab is associated with a different fragment which will be added to android:id="#+id/tab_content".
The menu_main.xml like this
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/action_calendar"
android:icon="#drawable/ic_title_date"
android:orderInCategory="100"
android:title="#string/calendar"
app:showAsAction="always" />
<item
android:id="#+id/action_notification"
android:icon="#drawable/ic_title_notification"
android:orderInCategory="200"
android:title="#string/notification"
app:showAsAction="always" />
</menu>
I have these code in my MainActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
return super.onOptionsItemSelected(item);
}
Fragment2 and Fragment3 have these code:
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
if (id == R.id.action_calendar)
{
showDatePicker();
return true;
}
return super.onOptionsItemSelected(item);
}
android:id="#+id/action_calendar" menuItem is a datePicker,and i want to use this menuItem to be filter to load data for fragment2 and fragment3.
Here is my question,when I navigate to the fragment3 and click the calendar menu and then change to fragment2,click the calendar,the system call onOptionsItemSelected method in fragment 3 ,not in fragment2 ?
I want calendar menu response to different fragment separately .
