Activity view shows up on fragment

I have button on my activity that show up on the fragment and only the button that show up , i did search about it and find out its a rendering issue but the answers didn't worked for me, here how it looks.
Fragment
Activity
is there any chance that the issue code be from the margin of the button
Fragment.java
public class Smsar extends Fragment {
public Smsar() {
// Required empty public constructor
}
View root;
Button mSmsar,mFinder;
#Override
public View onCreateView(LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
root= inflater.inflate(R.layout.fragment_smsar, container, false);
mSmsar=(Button)root.findViewById(R.id.smsar);
mFinder=(Button)root.findViewById(R.id.finder);
mSmsar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getActivity().onBackPressed();
}
});
mFinder.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Open Discover.
}
});
return root;
}
}

Dynamically added EditText is not visible when created

I have been reading about how to dynamically add an EditText field to my Linear Layout, every-time a user clicks a TextView (which has an onClick Listener attached).
I have had some mild success - I know that the EditText field is being created because when the button is clicked, all other elements move up as if something is being added to the screen.
My problem is that the EditText aren't visible and I haven't a clue why that is, so any help would be appreciated.
The the app isn't crashing so nothing to add in terms of the StackTrace and Log, as far as the app is concerned, everything is being created.

I clicked on my clear button and it doesn't work

THANK YOU FOR ALL OF YOUR HELP!! I NEED TO READ A TUTORIAL. :)
I know it's probably elementary and as you can tell I'm a newbie. I compared my code to others and don't see anything wrong. Thanks! When I click the clear Button after entering data, my edit fields are not cleared.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button clear = (Button)findViewById(R.id.btn_clear);
clear.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
EditText potsize = (EditText) findViewById(R.id.et_pot_size);
EditText tocall = (EditText) findViewById(R.id.et_to_call);
EditText bepercent = (EditText) findViewById(R.id.et_be_per);
potsize.setText("");
tocall.setText("");
bepercent.setText("");
TextView potoddscalc = (TextView)findViewById(R.id.tv_pot_odds_calc);
potoddscalc.setText("5");
}
});

Try this instead. I believe your problem may be arising from creating new EditTexts and TextView objects every time you click the clear button. In the below code, the EditTexts and TextView are declared only once ,in the OnCreate method. Also, getText().clear() is the "official" way of clearing the text from an EditText (not that it really makes a visual difference).
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button clear = (Button)findViewById(R.id.btn_clear);
EditText potsize = (EditText) findViewById(R.id.et_pot_size);
EditText tocall = (EditText) findViewById(R.id.et_to_call);
EditText bepercent = (EditText) findViewById(R.id.et_be_per);
TextView potoddscalc = (TextView)findViewById(R.id.tv_pot_odds_calc);
clear.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
potsize.getText().clear();
tocall.getText().clear();
bepercent.getText().clear();
potoddscalc.setText("5");
}
});
}

Cannot find EditText from FragmentActivity

I noticed that it cannot find the views when I am on a different tab.

I declared my first Fragment's elements here:
public static class LaunchpadSectionFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_section_launchpad, container, false);
Spinner spinner = (Spinner) rootView.findViewById(R.id.gender_options);
Spinner civilStatusSpinner = (Spinner) rootView.findViewById(R.id.civil_status);
Spinner positionSpinner = (Spinner) rootView.findViewById(R.id.position);
Spinner departmentSpinner = (Spinner) rootView.findViewById(R.id.department);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
Here's the function for my ActionBar:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
this.finish();
return true;
case R.id.action_save:
EditText code = (EditText) findViewById(R.id.code);
EditText name = (EditText) findViewById(R.id.name);
EditText address = (EditText) findViewById(R.id.address);
EditText birthDate = (EditText) findViewById(R.id.birthdate);
EditText mobile = (EditText) findViewById(R.id.mobile);
EditText workPhone = (EditText) findViewById(R.id.workPhone);
EditText email = (EditText) findViewById(R.id.email);
Spinner gender = (Spinner) findViewById(R.id.gender_options);
Spinner civilStatus = (Spinner) findViewById(R.id.civil_status);
EditText hiredDate = (EditText) findViewById(R.id.hired_date);
EditText location = (EditText) findViewById(R.id.location);
Spinner departmentId = (Spinner) findViewById(R.id.department);
CheckBox isAdmin = (CheckBox) findViewById(R.id.isAdmin);
return true;
case R.id.action_discard:
this.finish();
return true;
}
return super.onOptionsItemSelected(item);
}
All the Views would return null, these views are found on the first fragment. When I did not make the lat two fragments, I could find the views.
Any help would be greatly appreciated. Thanks!

On approach could be to handle your itemMenuClick in our Fragment itself. So you can handle them in your Fragment and get the Information you need: TUTORIAL
The other approach is to keep a Instance of all of your Fragments in your MainActivity globally and ask your Fragment for the values eg:
MainActivity:
Fragment1 _fragment1;
onCreate(..){
_fragment1 = new Fragment1();
}
onMenuItemSelected(....){
String test = _fragment1.getCustomText();
}
Fragment1:
EditText _test;
onCreate(...){
_test = _root.findViewById(R.id.et_test);
}
public String getCustomText(){
return _test.getText().toString();
}

Try given code
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
this.finish();
return true;
case R.id.action_save:
EditText code = (EditText) getView().findViewById(R.id.code);
EditText name = (EditText) getView().findViewById(R.id.name);
EditText address = (EditText) getView().findViewById(R.id.address);
EditText birthDate = (EditText) getView().findViewById(R.id.birthdate);
EditText mobile = (EditText) getView().findViewById(R.id.mobile);
EditText workPhone = (EditText) getView().findViewById(R.id.workPhone);
EditText email = (EditText) getView().findViewById(R.id.email);
Spinner gender = (Spinner) getView().findViewById(R.id.gender_options);
Spinner civilStatus = (Spinner) getView().findViewById(R.id.civil_status);
EditText hiredDate = (EditText) getView().findViewById(R.id.hired_date);
EditText location = (EditText) getView().getView().findViewById(R.id.location);
Spinner departmentId = (Spinner) getView().findViewById(R.id.department);
CheckBox isAdmin = (CheckBox) getView().findViewById(R.id.isAdmin);
return true;
case R.id.action_discard:
this.finish();
return true;
}
return super.onOptionsItemSelected(item);
}

DialogFragment is fullscreen. How to make it small

I have this DialogFragment. When I show it, it becomes fullscreen, I mean it overlaps the current screen. How to make it small like an AlertDialog?
I guessed it's because of the RelativeLayout so I wrapped the LinearLayout outside of RelativeLayout but nothing changes.
public class LoginDialogFragment extends DialogFragment {
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme);
}
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
final Bundle savedInstanceState) {
final View v = inflater.inflate(R.layout.login_dialog, container, false);
final EditText emailEditText = (EditText)v.findViewById(R.id.emailEditText);
final EditText passwordEditText = (EditText)v.findViewById(R.id.passwordEditText);
final Button loginButton = (Button)v.findViewById(R.id.loginButton);
loginButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(final View v) {
checkLogin(emailEditText.getText().toString(), passwordEditText.getText().toString());
}
});
return v;
}
}

Call setStyle(STYLE_NORMAL, android.R.style.Theme_Dialog); instead of setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme); in onCreate(). Did it help?
