ANDROID - How to move to other fragment from fragment

ANDROID - How to move to other fragment from fragment - android

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);

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

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() {

I solve it by surround the button with LinearLayout

OnClickListener and fragments causing application crash

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.

Why fragment layout cannot be displayed?

What have I missed out here? I wanted to open edit_information fragment from edit activity. It can display the Toast but not displaying the edit_information layout.
Edit
listViewEdit.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> listView, View view,
int position, long id) {
// Get the cursor, positioned to the corresponding listview_item_row in the result set
Cursor cursor = (Cursor) listView.getItemAtPosition(position);
// Get the state's capital from this listview_item_row in the database.
String ID =
cursor.getString(cursor.getColumnIndexOrThrow("_id"));
EditInformation fragment2 = new EditInformation();
Bundle bundle = new Bundle();
bundle.putString("ID", ID);
fragment2.setArguments(bundle);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.fragment1, fragment2);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
EditInformation
public class EditInformation extends Fragment {
String ID;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View edit_info = inflater.inflate(R.layout.edit_information, container, false);
Bundle bundle = this.getArguments();
if(getArguments()!=null)
{
ID=bundle.getString("ID");
}
Toast.makeText(getActivity(),"Edit_Information",Toast.LENGTH_LONG).show();
return edit_info;
}
}

Try using FrameLayout as a container for fragment instead of LinearLayout. I believe because of LinearLayout your fragment is getting created out of screen. where as FrameLayout will overlap your fragment on other Views.

Using Sliding tabs in a fragment

I'm working on an app where I am supposed to fragment my MainActivity into 2 fragments. One on the right whitch going to hold some textEdits and buttons, and one on the left that should hold some sliding tabs.
I already did the fragmentation part, and added tabs on the left fragment, but the problem is I don't know how to make the tabs slide. Please I really need your help. Thanks in advance.
This is what I wrote so far:

setContentView(R.layout.activity_app);
if (savedInstanceState == null) {
getSupportFragmentManager()
.beginTransaction()
.add(R.id.main_container_1, new MainTab())
.commit();
getSupportFragmentManager()
.beginTransaction()
.add(R.id.main_container_2, new StaticFragment())
.commit();
}
}
public static class MainTab extends Fragment {
private FragmentTabHost mTabHost;
//Mandatory Constructor
public MainTab() {
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_main_tab,container, false);
mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("fragmenta").setIndicator("Biometric operations"),
Tab1.class, null);
mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("DataBase operations"),
Tab2.class, null);
return rootView;
}
}
public static class Tab1 extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,

ANDROID - How to move to other fragment from fragment - android

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);
