I'm trying to use fragments to programatically change the text on a screen. To do this I'm setting up an on click listener on a text view and then if it's clicked starting a fragment manager, replacing the current fragment with the new fragment. However, this causes my app to crash when it's started.
From reading the crash report it seems like the error is happening at tv1.setOnClickLIstener...
Finally, Android Studio keeps giving me a type mismatch when I use fragment or support fragment. That is why you see android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
Java Code:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//begin transaction
android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
//replace the contents of the container with the new fragment
ft.replace(R.id.placeHolder, new SplashScreenFragment());
ft.commit();
TextView tv1 = (TextView) findViewById(R.id.whatIsHumanTrafficing);
tv1.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View view) {
android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.placeHolder, new whatIsHumanTrafficing());
ft.commit();
}
});
}
}

Fragment named human trafficking that I'm trying to inflate:
public class whatIsHumanTrafficing extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){
//inflate the layout for this fragment
return inflater.inflate(R.layout.what_is_human_trafficing, container, false);
}
}
You have used activity_main in your MainActivity as follows
setContentView(R.layout.activity_main);
and you are accessing whatIsHumanTrafficingnamed TextView in the same MainActivity which is not possible as it is not present in activity_main and which is present in another xml. So you are getting NullPointerException there.

I'm trying to make a fragment appear next to my activity view when I click on a button, but I keep having this error and I can't solve this.

EDIT:
I had to remove the second setContentView() to make it work.
i made a 2 fragment layout one for the login screen and the other for the Register screen and in the main screen i put a fragment for login screen and a button if the user want to register he click in that button and the register fragment appears to him and the login fragment disappear
the problem is after i press the register button in the main screen the login screen appears to be behind the register screen
here's a photo for it
login behind Register
i don't know what's the problem or i misunderstanding the fragments i don't know
here's the onclick method on the MainActity class
#Override
public void onClick(View view) {
String mytxt = inversebutton.getText().toString();
Fragment fragmentSign = new Signin();
Fragment fragmentregister = new Register();
if(mytxt.equals("Register")){ // call signin frame
android.support.v4.app.FragmentManager fragmentManager= getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragmentplace ,fragmentregister).commit();
inversebutton.setText("SignIn");
}else{ // call register fra

Rather than taking fragment tag in xml,it would be good for taking just a layout by giving its id and replace it by fragment transaction dynamically
In your layout, change it by taking simple Relative or Linear layout and must give that layout background,remove that fragment tag and replace fragment by java coding according to you need
and then replace it at start of your class in onCreate() method by->`
getSupportFragmentManager().beginTransaction().replace(R.id.fragmentplace, new Your_frag(), Constant.FragmentTags.fragmentTag).commit();
I think you should use DialogFragment which are here for those kind of popups in front of others.
You use it like that
DialogFragment registerFragment = RegisterFragment.newInstance(0);
registerFragment.show(getFragmentManager().beginTransaction(), "RegisterPopup");
And your fragment will be of class DialogFragment. Usually you pop a Dialog starting like that. Then depending on what you want many options are possible.
public class RegisterFragment extends DialogFragment {
...
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
...
}
}
And you can find the example on the Android Developer
DialogFragment
I made a progress-bar fragment; the goal is to show it whenever the buttons in my MainActivity are clicked. However, I encountered this dilemma (using Android 5.1):
https://gyazo.com/8632f6e50cdce599847258939cc4f109
Any ideas what's the deal here? I can't pin-point the problem. The only solution is to hide the button when clicked. It works but I interpret is as badly-written code.
Main Activity
#Override
protected void onCreate(Bundle savedInstanceState) {
final Button bRegister = (Button) findViewById(R.id.bRegister);
final Button bTest = (Button) findViewById(R.id.bTest);
bTest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.activity_register, progressFragment);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
ProressFragment
public class ProgressFragment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_progress, container, false);
ProgressBar pb = (ProgressBar) view.findViewById(R.id.progressBar);
pb.setVisibility(View.VISIBLE);
return view;
}
}

It happens because the two buttons have an elevation that is not 0 while your RelativeLayout in your Fragment have an elevation of 0.
You can fix it wrapping the RelativeLayout of the Activity in a FrameLayout, like this:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_register"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="googleplayservices.samples.android.teamtreehouse.com.kibbleuserc.RegisterActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Add all the views that you have inserted in your RelativeLayout -->
</RelativeLayout>
</FrameLayout>
However the optimized solution is to set the elevation in your Fragment's root View with ViewCompat.setElevation(View,int) but you have to know the right elevation to set to bring the View on top of the others. In this case you won't need the FrameLayout wrapper and the onDraw() and onLayout() calls will be optimized.
I have an Activity called summaryActivity includes a fragment called completionFragment which has a popup called payment popup which has an EditText component when focus to it I need to display the datePicker as popup inside the payment popup (PaymentDialog)
SummaryLayout => Completion Fragment => Payment popup (Dialog) => datepicker (Fragment + DialogFragment)
here is my code:

Payment Dialog (Popup):
public class PaymentDialog: BaseDialog
{
readonly Activity activity;
FrameLayout fragment_container;
public PaymentDialog (Activity activity)
: base (activity)
{
this.activity = activity;
}
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView (Resource.Layout.AddPaymentDetailsLayout);
SetCancelable (true);
var cancel = (Button)FindViewById (Resource.Id.sequenceCancelButton);
cancel.Click += (sender, e) => Dismiss ();
//LinearLayout layout = (LinearLayout)FindViewById (Resource.Id.dtpExpirationDateLayout);
EditText txtExpirationDate = (EditText)FindViewById (Resource.Id.txtExpirationDate);
fragment_container = (FrameLayout)FindViewById(Resource.Id.fragment_container);
txtExpirationDate.ShowSoftInputOnFocus = false;
txtExpirationDate.FocusChange +=txtExpirationDate_FocusChange;
void txtExpirationDate_FocusChange(object sender, View.FocusChangeEventArgs e)
{
if (e.HasFocus)
{
var fragment = activity.FragmentManager.FindFragmentById<ConfirmationFragment>(Resource.Id.contentFrame);
var fragTx = fragment.ChildFragmentManager.BeginTransaction();
var frag = new DatePickerFragment ();
fragTx.Add(fragment_container.Id, frag);
fragTx.Commit ();
}
}
So when I need to focus on the date field inside payment popup the fragment after it committed gives the following error
"No view found for id 0x7f0b007d (com.MyProjectName:id/fragment_container) for fragment DatePickerFragment{4266acd8 #0 id=0x7f0b007d}"
I have few suggestions.
1) I think ID fragment_container.Id is not correct, try R.id.fragment_container. Change code...
From:
fragTx.Add(fragment_container.Id, frag);
TO:
fragTx.Add(R.id.fragment_container, frag);
2) I suspect contentFrame is not a Fragment, as it should. This is from the code
FragmentManager.FindFragmentById<ConfirmationFragment>(Resource.Id.contentFrame);
3)
Try code: View view = activity().findViewById(R.id.fragment_container); in txtExpirationDate_FocusChange().
Does view object return null? IF so, then this is a hint of the problem.
Usually, if we want to go to other page. We use code
Intent i = new Intent(getApplicationContext(), Home.class);
startActivity(i);
finish();
I confuse to go to other page with fragment.
TEACHER_Class.java
public class TEACHER_Class extends Fragment {
Button tambahKelasButton;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.teacher_class, container, false);
tambahKelasButton = (Button) rootView.findViewById(R.id.tambah_kelas_button);
tambahKelasButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Fragment FRAGMENT = new TEACHER_AddClass();
FragmentManager fragmentManager = getActivity().getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
//I think I get error in here
fragmentTransaction.replace(R.layout.teacher_class, FRAGMENT);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
return rootView;
}
}
TEACHER_AddClass.java
public class TEACHER_AddClass extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.teacher_add_class, container, false);
return rootView;
}
}
I want to move from TEACHER_Class.java to TEACHER_AddClass.java
This is teacher_class.xml

FragmentManager fragmentManager = getActivity().getFragmentManager();
you should use getChildFragmentManager, to perform transaction from a Fragment
fragmentTransaction.replace(R.layout.teacher_class, FRAGMENT);
the first parameter has to be the id (R.id.) of the ViewGroup that hosts the Fragment itself, and not the id of layout.
I suspect R.id.layout.teacher_class is the fragment you want removed? The first argument for the replace function is the container holding the fragment, not the actual fragment to be replaced.
fragmentTransaction.replace([TARGET_CONTAINER], FRAGMENT);
