Cannot find EditText from FragmentActivity

Cannot find EditText from FragmentActivity - android

I am trying to save all the information entered from all EditTexts in each of my 3 Fragments. I am trying to get these information from an option button in my ActionBar.
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);
}

final EditText etPassword = (EditText) getView().findViewById(R.id.etPassword);
final Button btLogin = (Button) getView().findViewById(R.id.btLogin);
Button btlink = (Button) getView().findViewById(R.id.btlink);
btlink.setOnClickListener(new View.OnClickListener() {

If someone could i would be thankfull.

At first set rootView instead of getView().
final EditText etUtilizador = (EditText) rootView.findViewById(R.id.etUtilizador);
final EditText etPassword = (EditText) rootView.findViewById(R.id.etPassword);
final Button btLogin = (Button) rootView.findViewById(R.id.btLogin);
Button btlink = (Button) rootView.findViewById(R.id.btlink);
And use getActivity().
Return the Activity this fragment is currently associated with.
new Intent(getActivity(), registar.class);
Code Will
Intent registerIntent;
registerIntent = new Intent(getActivity(), registar.class);
getActivity().startActivity(registerIntent);

change
Intent registerIntent;
registerIntent = new Intent(login.this, registar.class);
login.this.startActivity(registerIntent);
To
Intent registerIntent = new Intent(getActivity(), registar.class);
startActivity(registerIntent);
also need to change
final EditText etUtilizador = (EditText) rootView.findViewById(R.id.etUtilizador);
final EditText etPassword = (EditText) rootView.findViewById(R.id.etPassword);
final Button btLogin = (Button) rootView.findViewById(R.id.btLogin);

public class login extends Fragment{
Context context;
#Override
onAttach(Activity activity){
context=(Context)activity;}
...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
...
registerIntent = new Intent(context, registar.class);

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 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");
}
});
}

// try this way

declare all three objects of Edittext in the oncreate method and then try it
enter code here #Override

public void onClick(View v)
{
swiech(v.getid())
{
case R.id.btn_clear:
potsize.setText("");

EditText prints a letter twice

I know this is kinda silly and weird question, but its really bugging me. As my post subject says, when I enter a letter in the edit text its printing twice. I tried to find the issue, but couldn't. Here is my code,
changecode.xml
<EditText
android:id="#+id/oldcode"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/changecodetxt"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="20dp"
android:hint="Enter Old Pass Code"
android:inputType="number"
android:password="true" />
<EditText
android:id="#+id/newcode"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/oldcode"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="20dp"
android:hint="Enter New Pass code"
android:inputType="number"
android:password="true" />
<EditText
android:id="#+id/renewcode"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/newcode"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="25dp"

android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="#drawable/button_style"

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#id/savenewcode"
android:layout_below="#id/renewcode"
android:gravity="center" >
<ToggleButton
android:id="#+id/cc_togglebutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:textOff="123"
android:textOn="ABC!##" />
</LinearLayout>
In MainActivity.java
oldcode = (EditText) findViewById(R.id.oldcode);
newcode = (EditText) findViewById(R.id.newcode);
renewcode = (EditText) findViewById(R.id.renewcode);
savenewcode = (Button) findViewById(R.id.savenewcode);
cc_toggle = (ToggleButton) findViewById(R.id.cc_togglebutton);
cc_toggle.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
boolean on = cc_toggle.isChecked();
if (on) {
oldcode.setInputType(InputType.TYPE_CLASS_TEXT);
newcode.setInputType(InputType.TYPE_CLASS_TEXT);
renewcode.setInputType(InputType.TYPE_CLASS_TEXT);
}
else {
oldcode.setInputType(InputType.TYPE_CLASS_NUMBER);
newcode.setInputType(InputType.TYPE_CLASS_NUMBER);
renewcode.setInputType(InputType.TYPE_CLASS_NUMBER);
}
}
});
Any kind of help or suggestion is much appreciated.

Android : on changing EditText background color, EditText style getting changed

Hi When I change the Background color of EditText of two EditText they are looking like both merging.
My layout code goes like this `
<EditText
android:id="#+id/editText4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text1"
android:singleLine="true" />
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text2"
android:singleLine="true" >
</EditText>
<AutoCompleteTextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:singleLine="true"
android:imeOptions="actionNext"/>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text3"
android:singleLine="true" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text4"
android:singleLine="true" />
</LinearLayout>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
`
and My Activity code goes like this
public class MainActivity extends Activity {
EditText editText1, editText2, editText3, editText4;
Button button;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
editText1.setBackgroundColor(getResources().getColor(android.R.color.primary_text_dark_nodisable));
editText3.setBackgroundColor(getResources().getColor(android.R.color.darker_gray));
}
});
}
private void init() {
editText1 = (EditText) findViewById(R.id.editText1);
editText2 = (EditText) findViewById(R.id.editText2);
editText3 = (EditText) findViewById(R.id.editText4);
button = (Button) findViewById(R.id.button1);
}
}
Refer the attached Screen shots below
Layout before clicking Button
Layout after clicking Button

As you can see here using EditText.setBackgroundColor(any color) will color your outline too. To keep the outline aspect i would recommend to include the edittext in a table row and use margin. Try this in your xml and see the result:
<TableRow
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:orientation="vertical" >
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/holo_orange_dark"
android:layout_margin="1dip"
android:text="cosmincalistru" />
</TableRow>

You have set the same id for both the edittext. #+id/editText2
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text3"
android:singleLine="true" />
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ems="10"
android:hint="Text4"
android:singleLine="true" />
