Handling Click Event for menu Used for Floating Action Button Options

I used a library recently that Provides a Floating Action Button and changing to a Something like Navigation bar by clicking on it.
but i cant set click Event for my navigation bar Items.
after Pressing on items i don't see any reaction!
Anyone can help me?
fabOptions = (FabOptions) findViewById(R.id.fabcontainer);
fabOptions.setButtonsMenu(R.menu.menu1);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu1, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.back:
newBack();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void newBack() {
Toast.makeText(this, "back", Toast.LENGTH_SHORT).show();
}
}

First of all you should have to use break whenever you use switch statement otherwise the program will go to default status. so use break; the code below.
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getId(); // Retrieve the id of the selected menu item
switch(id) {
case R.id.back:
newBack();
return true;
break;
case ...
}
return super.onOptionsItemSelected(item);
}

Focus ListView Items on Button Click

Is it possible to focus the List View Items through any button click?
Like i want that when user click on Floating Action Button then the listview gets focused. I dont want to show checkbox type layout on button clicked. I just want to show the same like in the screenshot on Button click.
What i did is I put the listview onItemLongClick code in the button click blocks but it doesnot work.
fabButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
listViewMessages.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
listViewMessages.setMultiChoiceModeListener(new MultiChoiceModeListener() {
#Override
public void onItemCheckedStateChanged(ActionMode mode, int position,
long id, boolean checked) {
tv.setText(listViewMessages.getCheckedItemCount()+ " Selected");
}
#Override
public boolean onActionItemClicked(final ActionMode mode, MenuItem item) {
switch (item.getItemId()) {
case R.id.menu:
}
});
mode.finish();
return true;
default:
return false;
}
}
#Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// Inflate the menu for the CAB
MenuInflater inflater = mode.getMenuInflater();
inflater.inflate(R.menu.contextual, menu);
fabButton.setVisibility(View.INVISIBLE);
fabButtonn.setVisibility(View.VISIBLE);
fabButtonn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
for ( int i=0; i< messageListAdapter.getCount(); i++ ) {
listViewMessages.setItemChecked(i, true);
}
}
});
return true;
}
#Override
public void onDestroyActionMode(ActionMode mode) {
fabButton.setVisibility(View.VISIBLE);
fabButtonn.setVisibility(View.GONE);
}
#Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// Here you can perform updates to the CAB due to
// an invalidate() request
return false;
}
});
With this code if user clcik on button then he/she has too long press items again to focus the list items which is not what i want. I want to focus items right when button click. Any explanation or link provided will be helpful

How to open New activity on click on Button in Action Bar?

This is my ActionBar, it has two buttons:
private void showActionBar() {
LayoutInflater inflator = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.activity_main_actions, null);
ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setCustomView(v);
}
I used this method to show buttons. I called this method in onCreate.
Now i want when i click on Any button which is in action bar New activity open.
For example i have AskActivity.java and MessageActivity.java
now when i click on ASK button AskActivity.java opens.
Is this possible?
I have used this but its not working.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Take appropriate action for each action item click
switch (item.getItemId()) {
case R.id.action_ask:
Intent i = new Intent(getApplicationContext(), AskActivity.class);
startActivity(i);
return true;
case R.id.action_message:
Intent ij = new Intent(getApplicationContext(), MessageActivity.class);
startActivity(ij);
return true;
default:
return super.onOptionsItemSelected(item);
}
}

I think it's because the onOptionsItemSelected method is related to MenuItem and not the CustomView. The two buttons are not option menu items, they are buttons inside the layout activity_main_actions. You have two choices - either create a new on click listener, as follows:
Button action_ask = (Button) findViewById(R.id.action_ask);
action_ask.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v){
// do something
}
}
Or, use the on click attribute method:
<Button
android:id="#+id/action_ask"
...
android:onClick="actionAskClicked" />
And then inside your Activity:
public void actionAskClicked() {
// do something
}
Same for the other button action_message. Hope this helps.

You need to create a method to open an activity from menu button click:
public boolean onOptionsItemSelected(MenuItem item) {
// Take appropriate action for each action item click
switch (item.getItemId()) {
case R.id.action_ask:
startActivity(AskActivity.class);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
protected void StartActivity(Class<?> cls) {
Intent intent = new Intent(activity, cls);
activity.startActivity(intent);
}

int id = item.getItemId();
if(id==R.id.action_search){
View v = (View) item.getActionView();
search = ( EditText ) v.findViewById(R.id.txt_search);
search.requestFocus();
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
search_cancle=(Button)v.findViewById(R.id.search_cancel);
search_cancle.setOnClickListener(new OnClickListener() {
#Override

item.collapseActionView(); // Here I have set it.....
search.setText("");
}
});

Android options menu button only works after second click

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.
