Open custom menu on tap of option menu

I have activity with custom actionbar(Basically custom layout xml), therefore I have created a custom menu button as well in layout file and showing a popup,
I am usingthis callback to showing same popup on tap of hardware option menu, but give a weird behaviour e.g this will open custom menu whenvery onresume is run.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//return super.onCreateOptionsMenu(menu);
showHideMenu();
return false;
}
can you please suggest where I can placeshowHideMenu(); will which work like custom option menu
//showHideMenu() code
private void showHideMenu() {
if (mPopUpMenu.isShowing())
dismissPopUpMenu();
else
showMenu();
}
private void dismissPopUpMenu() {
// dismiss menu
if (mPopUpMenu != null)
mPopUpMenu.dismiss();
}

You should look for an up keyevent:
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU) {
showHideMenu();
return true;
}
return super.onKeyUp(keyCode, event);
}
Include this for PopUp:
mPopUpMenu.getContentView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_MENU) {
// ... payload action here. e.g. popupMenu.dismiss();
return true;
}
return false;
}
});
Reference:
Detecting physical Menu key press in Android

you can use PopupMenu for showing custom menu.
for this you have to find a view to attach menu.and then you can wrote
//Creating the instance of PopupMenu
PopupMenu popup = new PopupMenu(MainActivity.this, button1);
//Inflating the Popup using xml file
popup.getMenuInflater().inflate(R.menu.popup_menu,popup.getMenu());
popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(MainActivity.this,"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();
return true;
}
});
popup.show();//showing popup menu

Menu key is triggered twice android

If I the press menu key, it is triggered twice in all of my app's Activities
I tried to override onKeyUp and onKeyDown but no use any suggestions as to why is this happening?? Thanks in advance code goes on like this..
public class MainActivity extends ActionBarActivity {
private MainActivityDrawer mainActivityDrawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Toolbar toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
mainActivityDrawer = (MainActivityDrawer) getSupportFragmentManager().findFragmentById(R.id.fragment_main_activity_drawer_in);
mainActivityDrawer.setUp(R.id.fragment_main_activity_drawer_in, (DrawerLayout) findViewById(R.id.mainDrawer1), toolbar);
new clicklisteners().execute();
DrawerLayout drawerLayout = ((DrawerLayout) (findViewById(R.id.mainDrawer1)));
drawerLayout.setStatusBarBackground(R.color.PrimaryColorDark);
registerReceiver(err, new IntentFilter("ERROR_LOG_BUTTON_CLICKED"));
//toolbar.setOnKeyListener(this);
}
#Override
public boolean onKeyMultiple(int keyCode, int repeatCount, KeyEvent event) {
return false;
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
return false;
}
#Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if(event.getAction()==KeyEvent.ACTION_UP)
{
if(event.getKeyCode()==KeyEvent.KEYCODE_MENU)
{
ShowToast("Hello");
return true;
}
}
if(event.getKeyCode()==KeyEvent.KEYCODE_BACK)
{
if(mainActivityDrawer.isOpened())
{
mainActivityDrawer.close();
}
else
{
finish();
}
}
return false;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater=getMenuInflater();
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
return super.onPrepareOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
......
}

It seems the library 'com.android.support:appcompat-v7:22.0.0' has a problem with the menu button ,When i made that v7:22.0.0 to v7:21.0.0 the menu key works properly

submit a query when click on search button in keyboard

I have search view in my fragment. when I click on it , keyboard is open and I can type text. I want when I click on search button in keyboard , my query send to my server and get result but I don't know how get search event. any solution?

You have to extend OnQueryTextListener, attach the listener and implement onQueryTextSubmit.
Example:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
searchView = (SearchView) menu.findItem(R.id.mActionSearch).getActionView();
searchView.setOnQueryTextListener(this);
return true;
}
#Override
public boolean onQueryTextSubmit(String query) {
//Do something here
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}

Pozzo Apps Answer is right
but for api below 11 and compat library you can use something like this :
MenuItem search_menu=(MenuItem)menu.findItem(R.id.action_search);
SearchView searchView =(SearchView)MenuItemCompat.getActionView(search_menu);

You can also apply setOnKeyListener on search view like as below:
searchview.setOnKeyListener(new View.OnKeyListener(
{
Public boolean onKey(View v, int keyCode, KeyEvent event)
{
if(event.getAction() == KeyEvent.ACTION_DOWN)
{
switch(keyCode)
{
Case KeyEvent.KECODE_ENTER:
// Apply action which you want on search key press on keypad
return true;
default:
break;
}
} return false;
}
});

You have to add new OnQueryTextListener, and implement onQueryTextSubmit. This also works in a fragment.
Example:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main_search, menu);
SearchView sv = (SearchView) menu.findItem(R.id.action_search).getActionView();
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
//Do something here
Toast.makeText(getActivity(), "Search: " + query, Toast.LENGTH_SHORT ).show();
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
super.onCreateOptionsMenu(menu,inflater);
}

How to disable the home button in android 4.0+ versions

I tried following code but it is not getting to disable the home button above 4.0 versions in android
public class DHActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dh);
getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.dh, menu);
return true;
}
#Override
public void onAttachedToWindow()
{
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
public boolean onKeyDown(int keyCode, KeyEvent event){
if (keyCode == KeyEvent.KEYCODE_HOME) {
Log.i("TESTE", "BOTAO HOME");
return true;
}
return super.onKeyDown(keyCode, event);
}
#Override
public void onBackPressed() {
}
}

In the lower versions of android you can catch the home button , in later versions for security reason Google not allowing to override home button press.

Android don't want to see the OptionMenu

I have added a button in the action bar, it works fine but if I press the physical menu button, the menu appears action_settings. Instead I want to use only the menu in the ActionBar and not that of the physical menu button.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
getActivity().getMenuInflater().inflate(R.menu.menu_scegli, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.add_c:
Intent intent = null;
intent = new Intent(getActivity(), Inserisci_.class);
startActivity(intent);
return true;
case R.id.action_settings:
return false;
default:
return super.onOptionsItemSelected(item);
}
}

You can try overriding onKeyDown method in your activity and returning true if the menu key was pressed - this will effectively prevent android from internally handling the menu key:
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_MENU) {
return true;
}
else {
return false;
}
}
