I have 3 tabs and all of them has lists inside(different ones of course). When i click on tab I see the proper result(result which i would like to get).
I know how to get the clicked item info and make request to database about that item and get result and create new intent and put that result in it as a extra. BUT i don't know how I can display my result inside the same fragment without creating new intent. Because when i create new intent and show result in new intent my tabs obviously disappears, but i need them always to be there.
My main activity:
public class MainActivity extends SherlockFragmentActivity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowTitleEnabled(true);
Tab tab = actionBar.newTab()
.setText("Dictionary")
.setTabListener(new DictionaryFragment())
.setIcon(R.drawable.android);
actionBar.addTab(tab);
tab = actionBar.newTab()
.setText("Play")
.setTabListener(new PlayFragment())
.setIcon(R.drawable.apple);
actionBar.addTab(tab);
tab = actionBar.newTab()
.setText("Manage")
.setTabListener(new ManageFragment())
.setIcon(R.drawable.apple);
actionBar.addTab(tab);
}
}
One of my fragments:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
built_in_DB_setup dbOpenHelper = new built_in_DB_setup(getActivity().getBaseContext(), DB_NAME);
database = dbOpenHelper.openDataBase();
fillFreinds();
ArrayAdapter<String> adapter = new
ArrayAdapter<String>(getActivity().getBaseContext(), android.R.layout.simple_expandable_list_item_1, friends);
setListAdapter(adapter);
return super.onCreateView(inflater, container, savedInstanceState);
}
And here is the item click listener inside this class
public void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
String a=getData(((TextView) v).getText().toString());
Intent i = new Intent("com.example.fragmenttest.VIEWWORD");
i.putExtra("result", a);
startActivity(i);
}
Ones I have String a which i have got from onListItemClick how can I replace current Tab data with this string?

I am working with Android Studio and I want to retrieve data from Firestore and use the document data as information for individual list items in the RecyclerView container.
Basically the components are an Activity consisting of a Fragment which houses the RecyclerView. This is the code I used in my Fragment to obtain and display the data (the one in the code is a sample):
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_transport_requests_client, container, false);
firebaseAuth = FirebaseAuth.getInstance();
db = FirebaseFirestore.getInstance();
RecyclerView recyclerView = view.findViewById(R.id.recyclerView);
swipeContainer = view.findViewById(R.id.swipeContainer);
final ArrayList<String> list = new ArrayList<>();
DocumentReference documentReference = db.collection("transportRequests").document("T_client#eldereach.com_23 May 20 03:19 PM_");
documentReference.get().addOnCompleteListener(new OnCompleteListener<DocumentSnapshot>() {
#Override
public void onComplete(#NonNull Task<DocumentSnapshot> task) {
if (task.isSuccessful()) {
DocumentSnapshot document = task.getResult();
assert document != null;
list.add((String) document.getData().get("email"));
}
}
});
listAdapter = new TransportRequestsListAdapter(list);
recyclerView.setAdapter(listAdapter);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
recyclerView.setLayoutManager(layoutManager);
The issue here isn't that the code doesn't work, I think the retrieval works, however, nothing is displayed when the Fragment is launched. The data is only displayed when I click the Fragment. This doesn't occur when I just add random strings instead of data from the document, e.g. list.add("random data"). Any idea what is the issue here? Thanks in advance!
been alright so far. I try to use docs or find my issues.
However my mainActivity has 4 buttons. These buttons depending on which view is clicked passes the R.id.button. I pass this value into an intent which Activity2 uses bundle to get id integer. I then setContentView using this.
However im having issues getting correct view to inflate now, it seems like its loading an old layout. My aim is to inflate 3 separate layout on Activity2 depending which button was clicked.
I know my other other button does inflate another activity and get proper xml layout.
Why are my other 3 buttons not inflating on Activity2 properly?
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
Button pizza;
Button hamburger;
Button icecream;
Button history;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pizza = findViewById(R.id.buttonPizza);
hamburger = findViewById(R.id.buttonBurger);
icecream = findViewById(R.id.buttonIceCream);
history = findViewById(R.id.buttonHistroy);
pizza.setOnClickListener(this);
hamburger.setOnClickListener(this);
icecream.setOnClickListener(this);
history.setOnClickListener(this);
}
#Override
public void onClick(View v){
int idView = v.getId();
switch(v.getId()) {
case R.id.buttonBurger : startOrderActivity(R.layout.burger_layout);
makeToast(idView);
break;
case R.id.buttonPizza : startOrderActivity(R.layout.pizza_layout);
makeToast(idView);
break;
case R.id.buttonIceCream : startOrderActivity(R.layout.icecream_layout);
makeToast(idView);
break;
case R.id.buttonHistroy : startOrderActivity(R.layout.history_layout);
makeToast(idView);
break;
}
}
private void startOrderActivity(int id){
if(id != R.layout.history_layout) {
Intent intentOrder = new Intent(this, MakeOrderActivity.class);
intentOrder.putExtra("layout", id);
startActivity(intentOrder);
}
else {
Intent intentOrder = new Intent(this, OrderHistoryActivity.class);
intentOrder.putExtra("layout", id);
startActivity(intentOrder);
}
}
public void makeToast(int id){
String txt = String.valueOf(id);
Toast newToast = Toast.makeText(getApplicationContext(),txt,Toast.LENGTH_LONG);
newToast.show();
}
}
public class MakeOrderActivity extends AppCompatActivity {
Button placeOrderButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle data = getIntent().getExtras();
int layoutNum = data.getInt("layout");
setContentView(layoutNum);
placeOrderButton = findViewById(R.id.placeOrder);
}
#Override
protected void onStart() {
super.onStart();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.order, menu);
return true;
}
public void onCheckboxClicked(View view){
}
}
Answer is to create a View which is created by getInflator.

I'm trying to use a RadioGroup widget inside a fragment instead of an activity. I'm getting an error on the following line of code:
RadioButton button = new RadioButton(this);
I'm not sure what to pass instead of 'this'
I believe the problem is either in the snippet above or here:
RadioGroup group = (RadioGroup) getView().findViewById(R.id.radioGroup);
Full code:
public class fragment1 extends Fragment {
private Button btnNextFrag;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment1_layout, container, false);
createRadioButtons();
return view;
}
private void createRadioButtons() {
RadioGroup group = (RadioGroup) getView().findViewById(R.id.radioGroup);
String[] questions1 = getResources().getStringArray(R.array.question_1_answers);
for (int i=0;i<questions1.length;i++){
String question = questions1[i];
RadioButton button = new RadioButton(this);
button.setText(question);
group.addView(button);
}
}
}
The constructor requires context so use getActivity() instead of this. You can also use getContext().
public class fragment1 extends Fragment {
private Button btnNextFrag;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment1_layout, container, false);
createRadioButton(view);
return view;
}
private void createRadioButton(View view) {
RadioGroup group = (RadioGroup)view.findViewById(R.id.radioGroup);
String[] questions1 = getResources().getStringArray(R.array.question_1_answers);
for (int i=0;i<questions1.length;i++){
String question = questions1[i];
RadioButton button = new RadioButton(getActivity());
button.setText(question);
group.addView(button);
}
}
}
When I click first or second item from 1st array list I get first item from array list two, but I need if i click second item on array list 1 I get shown second item from list two
public class SecondActivity extends AppCompatActivity {
ListView listView;
ArrayList<String> 1stArrayList;
ArrayList<String> 2ndArrayList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
listView = (ListView) findViewById(R.id.listView);
1stArrayList = new ArrayList<>();
1stArrayList .add("A");
1stArrayList .add("B");
1stArrayList .add("C");
2ndArrayList = new ArrayList<>();
2ndArrayList.add("1");
2ndArrayList.add("2");
2ndArrayList.add("3");
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, R.layout.item, 1stArrayList);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
String 2ndArrayList= listView.getItemAtPosition(position).toString();
SharedPreferences settings = getSharedPreferences("PREFS", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("2ndArrayList ", 2ndArrayList );
editor.apply();
Intent intent = new Intent(getApplicationContext(), ThirdActivity.class);
startActivity(intent);
}
});
}
}
A possible solution would be getting the value directly from the array using the position of the view clicked. Like the following:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
String secListItem = secArrayList.get(position);
SharedPreferences settings = getSharedPreferences("PREFS", 0);
SharedPreferences.Editor editor = settings.edit();
editor.putString("2ndArrayList", secListItem );
editor.apply();
Intent intent = new Intent(getApplicationContext(), ThirdActivity.class);
startActivity(intent);
}
});
But you have to be sure that both the arrays will have the same size or you may have an IndexOutOfBoundsException.
Another solution would be using some Map with the values from arraylist1 and arraylist2, implementing a custom adapter that extends BaseAdapter, populating the views with the values from the first array with getView() and using getItem() to return the values from the second list, but that's harder to do.
Also if you don't mean to persist the item and only transfer them between activities, you can use the Intent to do it. In this way:
Intent intent = new Intent(getApplicationContext(), ThirdActivity.class);
Intent.putExtra("2ndArrayList", secListItem);
startActivity(intent);
And recover in the third activity with something like:
String secArrayItem = "";
Bundle extras = getIntent().getExtras();
if (extras != null) secArrayItem = extras.getString("2ndArrayList");
i am new to android java programming. I am adding a custom dynamic layout to a dialog box. i have 2 classes , Mainactivity.java and Getval.java
The Mainactivity.java create a dialoge and Getval generates dynamic layout at run time.
Every thing works good but when it tried to call Getval.java's method, it gives an exception. here is the code of both classes.
The g.setval(); in Mainactivity.java cause problem.
:::::Mainactivity.java:::::
public class MainActivity extends Activity {
private Button button;
public Getval g=new Getval();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button= (Button) findViewById(R.id.buttonShowCustomDialog);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//set up dialog
g.setval();
Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.attributewin);
dialog.setTitle("Attribute Window");
dialog.setCancelable(true);
dialog.show();
}
});
::::Getval::::
public class Getval extends Activity{
String names[]={"test","chaeck","kajsdhasj","dlasdig"};
String values[]={"test","chaeck","kajsdhasj","dlasdig"};
String test[]={"Attribut","Value"};
public void setval(){
TableLayout tl = (TableLayout) findViewById(R.id.tly);
Button b=new Button(this);
for (int i = 0; i < names.length; i++) {
//Row
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
//TextViews
TextView tv0 = new TextView(this);
tv0.setText(names[i]);
tv0.setMaxWidth(75);
TextView tv1 = new TextView(this);
tv1.setText(values[i]);
tv1.setMaxWidth(150);
View line = new View(this);
line.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 1));
line.setBackgroundColor(Color.BLACK);
//Setting Views
tr.addView(tv0);
tr.addView(tv1);
tl.addView(tr);
tl.addView(line);
}
//Button Row
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));
tr.setGravity(0x11);
b.setId(100);
b.setText("Return");
b.setGravity(0x11);
tr.addView(b);
tl.addView(tr);
}
}
Looking over this without seeing your xml or complete code (or exception that is thrown), I would be willing to guess that you are trying to inflate/modify a view (R.id.tly) from an activity other than the one where it was originally inflated from (MainActivity).
Generally speaking, you can't do this without doing some tricks with cross activity handlers or other methods. Perhaps change your code to inflate the views (R.id.tly) in MainActivity (and in your dialog if it is inside of R.layout.attributewin), do your processing in Getval, return them to MainActivity so it can populate the views.
But again, this is just a guess, since I don't see your xml or exception.
