Fragment does not close

I'm creating a fragment which is supposed to act like a menu. I have successfully inflated it to the activity where I wanted it to be, however I now I realise that I cannot close the fragment. Furthermore I am able to scroll the contents of the activity which the fragment is placed over. How can I edit my code in such a way that the fragment will close after an action on the activity is detected, or one of it's contents is clicked?
I created the fragment by simply adding a fragment via new -> Fragment -> Fragment(Blank). I have not touched any of the code and have initialized the fragment like so in a on click:
findViewById(R.id.Menu).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.enter_from_left, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_left);
MenuFragment menuFragment = new MenuFragment();
fragmentTransaction.replace(android.R.id.content, menuFragment);
fragmentTransaction.commit();
}
});
This is what it looks like, ignore the horrendous design.

how to remove fragment over an activity layout

I am really new to android development. I have created a simple main activity and add an icon on top left. Clicking it I can show a blank fragment.on my screen replacing a layout which is loaded in onCreate method. Now clicking another icon I want to hide that fragment and load that layout again. How to do that?? any helps??
Below is my code
//part of oncreate where my layout is loaded
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
// part of code when icon clicked and fragment is loaded
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
BlankFragment frag = new BlankFragment();
fragmentTransaction.replace(R.id.content_main, frag);
fragmentTransaction.commit();
//another nearby icon clicked
//now i want to replace this fragment from content_main layout
//what code to add??

If I got your question right, then this is the right answer I guess.
//keep track of all fragments you add by tagging
fragmentTransacaction.add(R.id.content, new FragA(), "first");
//and when removeing
Fragment f = getFragmentManager().findFragmentByTag("first");
if(f!=null) fragmentTransac.remove(f);
fragmentTransac.commit();
I got this from here

You can toggle visibilty by below code.
public void toggleVisibility(Fragment fragment){
FragmentTransaction transaction = getFragmentManager().beginTransaction();
if (fragment.isHidden()) {
transaction.show(fragment);
} else {
transaction.hide(fragment);
}
transaction.commit();
}

how to switch from one fragment to another fragment android

Hi I have 5 fragments Now first time when I go to Activity of that fragments then default First fragment is called,then on first Fragment there is a button by clicking that button I go to the second fragment,similarly in Second fragment There is a button and clicking that button I go to the third fragment and so on.
Now My Question is that Current I am on Fifth fragment ,Now I want to go fifth fragment to second fragment,what should I do for this?
Can any one please tell me?

You can pop the fragment by name. While adding fragments to the back stack, just give them a name.
fragmentTransaction.addToBackStack("frag2");
Then in fragment5, pop the back stack using the name ie.. frag2 and include POP_BACK_STACK_INCLUSIVE
someButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fm = getActivity()
.getSupportFragmentManager();
fm.popBackStack ("frag2", FragmentManager.POP_BACK_STACK_INCLUSIVE);
}
});

Here is the method to add and replace fragment.
public void addReplaceFragment(Fragment fragment, int addOrReplace) {
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
switch (addOrReplace) {
case addFragment:
transaction.add(R.id.frame_containerforsearchable, fragment);
transaction.commit();
break;
case replaceFragment:
transaction.replace(R.id.frame_containerforsearchable, fragment);
transaction.commit();
break;
default:
break;
}
}
call of fragment is..
addReplaceFragment(currencyFragmentWithSearch, replaceFragment);
replaceFragment integer variable
currencyFragmentWithSearch Fragment instance

You can always do this :)
getActivity().getSupportFragmentManager().replace(R.id.yourFrameLayout,new Fragment2(),"FRAG2");
OR
Fragment fragment = getActivity().getSupportFragmentManager().findFragmentByTag("FRAG2");
getActivity().getSupportFragmentManager().replace(R.id.yourFrameLayout,,"FRAG2");

Try this code:
Fragment fragment = new SecondFragmentName();
FragmentManager fm = getActivity().getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.content_frame, fragment);
ft.commit();

just small correction to mudit_sen code. It is working, only if you add .beginTransaction. Thank you.
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.FrameLayoutId,new FragmentName()).commit();

Opening Fragment from a DialogFragment (replacing the Dialogs parent)

Let's say I have Fragment A, from which I open a DialogFragment like this:
FragmentActivity fragmentActivity = (FragmentActivity) view.getContext();
FragmentTransaction ft = fragmentActivity.getSupportFragmentManager().beginTransaction();
Fragment prev = fragmentActivity.getSupportFragmentManager().findFragmentByTag("dialog");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);
DialogFragment fragmentDialog = MyDialogFragment.newInstance();
fragmentDialog.show(ft, "dialog");
From this Dialog, after clicking (positive / neutral / negative) button, I want to open Fragment B, which should replace Fragment A.
In the Dialog's onClick method I run a callback method of parent Activity:
#Override
public void onClick(DialogInterface dialog, int which) {
switch(which) {
case DialogInterface.BUTTON_NEUTRAL:
detailsCallbacks.openMoreDetails();
break;
}
}
And finally my Activity's openMoreDetails() method looks like this:
#Override
public void openMoreDetails() {
Fragment fragmentB = Fragment.newInstance();
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.fragment_container, fragmentB);
ft.addToBackStack(null);
ft.commit();
}
What I get is strange. Fragment B blinks on the screen just for a fraction of a second and then is replaced (covered?) by Fragment A again.
When I click the 'up' button I get back from Fragment A, so none of these transactions were added to the back stack. I would like to show Fragment B and then, when pressing the 'up' button, go back to Fragment A.
Is it somehow possible? And what's wrong with my approach?

Just had the same problem:
Fragment A display a custom dialog fragment.
At click on one of the buttons of the dialog fragment, I wanted to remove the dialog and show Fragment B.
Fragment B was displayed and instantly disappear. My screen was displaying Fragment A again.
What was wrong on my initial implementation:
private void onClickInscription() {
FragmentInscription frag = FragmentInscription.newInstance();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.main, frag);
ft.addToBackStack(null);
ft.commit();
dismiss();
}
And the correct one:
private void onClickInscription() {
dismiss();
FragmentInscription frag = FragmentInscription.newInstance();
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.main, frag);
ft.addToBackStack(null);
ft.commit();
}
So try to call dismiss first on your dialog then apply the FragmentTransction

I know this it's been a long time since the problem was posted, but I solved it by adding a if(fragmentB.getView != null) before the replace statement.
It finally doesn't do the flash and disappear thing. (:

You shouldn't be opening the dialog from FragmentA. Implement a callback from your FragmentA to your activity and let the activity handle all fragment transactions.

Switch between two fragments

I want to do the following. There are two fragments first and second. Necessary make the transition between them. When I go from first fragment in the second, first stored in the stack. When I click the Back button the second fragment is removed and returned first fragment from the stack. Again I can not go in the second fragment - it has been deleted. How can I solve this problem?
In main activity (callback for Fragment1):
#Override
public void onNavigate() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment1 newFragment1 = (Fragment1) getFragmentManager().findFragmentByTag("frag_1");
Fragment2 newFragment2 = (Fragment2) getFragmentManager().findFragmentByTag("frag_2");
ft.replace(R.id.main, newFragment2);
ft.remove(newFragment1);
ft.addToBackStack(null);
ft.commit();
}
Fragments I added dynamically:
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.add(R.id.main, new Fragment1(), "frag_1");
ft.add(R.id.main, new Fragment2(), "frag_2");
ft.commit();

I solved this problem :). I hide first fragment and add transaction to the back stack. When I click button Back I return to fragment
#Override
public void onNavigate() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
Fragment1 newFragment1 = (Fragment1) getFragmentManager().findFragmentByTag("frag_1");
ft.hide(newFragment1);
ft.addToBackStack(null);
ft.commit();
}
