How to go previous activity searchview back button?

I have a very simple question. I have implemented searchview in my menu. So the activity starts with expanded searchview. And now when I press back button, the searchview first collapse and goes back to previous activity.
Here's my code
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
searchItem.expandActionView();
SearchView mSearchView = (SearchView) MenuItemCompat.getActionView(searchItem);
mSearchView.setQueryHint(getString(R.string.search_hint));
mSearchView.setIconifiedByDefault(false);
mSearchView.setFocusable(true);
mSearchView.setIconified(false);
mSearchView.requestFocus();
mSearchView.setGravity(Gravity.END);
mSearchView.setTextDirection(View.TEXT_DIRECTION_RTL);
//mSearchView.setLayoutParams(new Toolbar.LayoutParams(Gravity.END));
//String searchQuery = getIntent().getStringExtra("SEARCH");
//SearchActivity.this.myAdapter.filter(searchQuery);
TextView searchText = mSearchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
//searchText.setText(searchQuery);
Typeface customFont = Typeface.createFromAsset(this.getAssets(), "fonts/font.ttf");
searchText.setTypeface(customFont);
try {
ThaanaUtils.thaanafyTextViewSubclass(searchText, "fonts/faruma.ttf");
}catch (IOException e){
e.printStackTrace();
}
searchText.addTextChangedListener(new ThaanaTextWatcher());
View xIcon = ((View) mSearchView.findViewById(R.id.search_plate));
xIcon.setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
SearchActivity.this.myAdapter.filter(newText);
return true;
}
});
MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
onBackPressed();
return true;
}
});
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_favorites) {
//Intent newActivity = new Intent(SearchActivity.this,FavoritesActivity.class);
//startActivity(newActivity);
}
return super.onOptionsItemSelected(item);
}
#Override
public void onBackPressed()
{
finish();
}
#Override
public boolean onSupportNavigateUp() {
onBackPressed();
return true;
}
But I don't want to show searchview collapsing when pressed back button. I want to go back to previous activity without collapsing searchview.
How can I achieve that?
Any help is appreciated.

Override the onBackPressed() method in your activity and then put your activity redirection code inside the method. This will solve your problem. Happy coding!
#Override
public void onBackPressed() {
// enter your activity redirection code here.
}
If you didn't call finish() on your previous activity, then just call finish() inside the onBackPressed method. This will destroy the current activity(search activity) and will load previous one. Else you need to go through the usual way by declaring an intent.

Set Share Intent is never used

I'm trying to add a share button to my actionbar. The icon displays correctly, however when pressed, nothing happens. It says that my setShareIntent is never used. How do I go about using this?
} #Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
// Locate MenuItem with ShareActionProvider
MenuItem item = menu.findItem(R.id.menu_item_share);
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
// Return true to display menu
return true;
}
// Call to update the share intent
private void setShareIntent(Intent shareIntent) {
if (mShareActionProvider != null) {
mShareActionProvider.setShareIntent(shareIntent);
}
}

First Override method onOptionsItemSelected in your activity.
Here is the code you can try.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
MenuItem item = menu.findItem(R.id.menu_item_share);
mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(item);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.menu_item_share) {
doShare();
}
return super.onOptionsItemSelected(item);
}
private void doShare() {
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "I'm Sharing Data");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Here is my data");
startActivity(Intent.createChooser(shareIntent, "Share myData to.."));
}
Refer the Docs :- Here
Well, I don't see any use of method setShareIntent(). And, In your, it's giving you warning "setShareIntent is never used" because you are not calling that method anywhere in your code.

You should set listener:
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.mainmenu, menu);
// Locate MenuItem with ShareActionProvider
MenuItem item = menu.findItem(R.id.menu_item_share);
item.setOnMenuItemClickListener(new OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
// do something
return true;
}
});
// Fetch and store ShareActionProvider
mShareActionProvider = (ShareActionProvider)MenuItemCompat.getActionProvider(item);
// Return true to display menu
return true;
}

Android onOptionsItemSelected method of Fragment doesn't get called

there are many questions about the topic but i can't figure out my problem. I have a menu declared in my MainActivity(ActionBarActivity). Now i want to work with MenuItem in onOptionsItemSelected of a Fragment class. Here is my MainActivity methods
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// toggle nav drawer on selecting action bar app icon/title
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action bar actions click
switch (item.getItemId()) {
case R.id.add_note:
createNewNote();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void createNewNote() {
Intent addIntent = new Intent(MainActivity.this, AddNote.class);
startActivity(addIntent);
}
And Fragment methods
#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) {
switch (item.getItemId()) {
case R.id.add_note:
Toast.makeText(getActivity(), "Entered into fragment", Toast.LENGTH_LONG).show();
createNewNote();
return true;
default:
break;
}
return super.onOptionsItemSelected(item);
}
private void createNewNote() {
Intent addIntent = new Intent(getActivity(), AddNote.class);
startActivity(addIntent);
}
Here in MainActivity onOptionsItemSelected get called even in Fragment but doesn't in Fragment as i don't see Toast in Fragment. I think something is missed in my code. Thanks in advance.

inside onOptionsItemSelected() in activity inside your switch after calling createNewNote() instead of returning true return super.onOptionsItemSelected(item)

you must call setHasOptionsMenu() inside onCreate of fragment for menu related method to work.

Your onCreateOptionsMenu() method does not inflate the menu file:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
}

Where to declare onOptionsItemSelected for global use?

I'm very new to Android development.
In my MainActivity.java file, I've declared an onOptionsItemSelected(MenuItem menu) method that allows the user to jump between the current MainActivity.java page and another page I created called Settings.java.
When the user goes to the Settings.java page, and they click on the Home option from the menu, nothing happens. I know this is because the onOptionsItemSelected(MenuItem menu) is only defined in the MainActivity.java class and not in the Settings.java class.
I'm overcoming this right now by copying the onOptionsItemSelected(MenuItem menu) from MainActivity.java into Settings.java. But this is very redundant.
Where should I be declaring methods that could be reused in different classes?
MainActivity.java
public class MainActivity extends Activity {
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
showMsg("Settings Clicked");
this.startActivity(new Intent(this, Settings.class));
return true;
case R.id.action_home:
showMsg("Home clicked");
this.startActivity(new Intent(this, MainActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void showMsg(String msg) {
Toast toast = Toast.makeText(this.getBaseContext(), msg, Toast.LENGTH_LONG);
toast.show();
}
}
Settings.java
public class Settings extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.settings);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_settings:
this.startActivity(new Intent(this, Settings.class));
return true;
case R.id.action_home:
this.startActivity(new Intent(this, MainActivity.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

If you create an Activity called BaseActivity that has your common onOptionsItemSelected() code then extend this class to create MainActivity and Settings both of these classes will use the super class' (i.e. BaseActivity's) onOptionsItemSelected().
Another approach is to switch to Fragments, since Fragments use the host Activity's onOptionsItemSelected() as well as their own. Both of these tactics allow you to use "centralized" code and not have to maintain multiple "cut and paste" copies.

Menu Button Trouble on Android

I am trying to use the menu button on the phone but for some reason it is not working? There is no error but the when I press menu it does nothing. I am running a 2.3.3 Android emulator.
Here is my Activity:
public boolean onCreatOptionsMenu(Menu menu){
MenuInflater Inflater = getMenuInflater();
Inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case R.id.MenuClass:
startActivity (new Intent ("com.clayton.calendar.TOCLASS"));
return true;
case R.id.MenuFriends:
startActivity (new Intent ("com.clayton.calendar.TOFRIENDS"));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Here is my XML:
<item
android:id="#+id/MenuClass"
android:title="Open Classes"/>
<item
android:id="#+id/MenuFriends"
android:title="Open Friends"/>

Try this:
#Override
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater Inflater = getMenuInflater();
Inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case R.id.MenuClass:
startActivity (new Intent ("com.clayton.calendar.TOCLASS"));
return true;
case R.id.MenuFriends:
startActivity (new Intent ("com.clayton.calendar.TOFRIENDS"));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
(Don't put this inside the onCreate() method)
