How to Refresh Fragments with swipe to refresh widget?

How to Refresh Fragments with swipe to refresh widget? - java

I wanted to refresh my fragment with SwipeToRefresh widget.
This is my XML Code
<?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:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradient_drawable"
android:padding="10dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".Fragment_1">
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="#+id/swipe"
android:layout_width="match_parent"
android:layout_height="match_parent">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar
android:id="#+id/progress"
android:layout_width="76dp"
android:layout_height="64dp"
android:elevation="10dp"
android:foregroundGravity="center"
android:indeterminateTint="#color/black"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.84" />
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:padding="5dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</FrameLayout>
and this is my JAVA code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_1, container, false);
newconfig= getResources().getConfiguration();
db=new DBHandler(getActivity());
swipeRefreshLayout=view.findViewById(R.id.swipe);
recyclerView=view.findViewById(R.id.listview);
progressBar=view.findViewById(R.id.progress);
if(book.size()==0) {
book = db.readCourses();
}
progressBar.setVisibility(View.GONE);
BookFragAdapter adapter = new BookFragAdapter(Fragment_land1.this,book);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(),RecyclerView.VERTICAL,false));
recyclerView.setAdapter(adapter);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
this.onRefresh();
getFragmentManager().beginTransaction().detach(Fragment_land1.this).attach(Fragment_land1.this).commit();
swipeRefreshLayout.setRefreshing(false);
}
});
return view;
}
When I try to refresh it doesn't refresh and the widget doesn't stops after 250ms. I assume that the code inside onRefreshListener is not actually executing therefore the next line is ignored. I don't know how change it with. I surfed in Stackoverflow and Developer.android none of the answers solved my problem. Can anyone help me?

first check that you have added dependencies in build.gradle file
i.e implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"
Secondly swipe to refresh layout tag should start from start instead of fragment
for eg :
<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/swipe"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/gradient_drawable"
android:padding="10dp"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".Fragment_1">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar
android:id="#+id/progress"
android:layout_width="76dp"
android:layout_height="64dp"
android:elevation="10dp"
android:foregroundGravity="center"
android:indeterminateTint="#color/black"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.84" />
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:padding="5dp"/>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
third then write swipeRefreshLayout.setOnRefreshListener code in java file

Why ListView is always empty in Fragment Dialog

The Dialog shows properly but the listview is always empty.
Here is what I get when I launch the Activity
enter image description here
public class MainFragment extends Fragment {
String[] cities = {"Tanger", "Meknes", "Casablanca",
"Fes", "Tetouan", "Taza", "Rabat"};
Dialog dialog;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
TextView currentCity = view.findViewById(R.id.city);
currentCity.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog = new Dialog(getContext());
dialog.setContentView(R.layout.dialog_searchable_spinner);
dialog.getWindow().setLayout(800, 1000);
View spinnerView = getLayoutInflater().inflate(R.layout.dialog_searchable_spinner, container, false);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.show();
EditText searchTextView = spinnerView.findViewById(R.id.editText);
ListView citiesListView = spinnerView.findViewById(R.id.citiesListView);
ArrayAdapter<String> adapter = new ArrayAdapter<>(getActivity(), android.R.layout.simple_list_item_1, cities);
citiesListView.setAdapter(adapter);
}

It is a problem with your layout. ConstraintLayout is somehow hiding the listview. You have to do some changes in your layout files. For example, this has worked for me using LinearLayout
Dialog dialog;
dialog = new Dialog(this);
dialog.setContentView(R.layout.dialog_searchable_spinner);
dialog.getWindow().setLayout(800, 1000);
//View spinnerView = getLayoutInflater().inflate(R.layout.dialog_searchable_spinner,binding.getRoot());
//dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
ListView citiesListView = dialog.findViewById(R.id.citiesListView);
ArrayAdapter<String> adapter = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_list_item_1, cities);
citiesListView.setAdapter(adapter);
dialog.show();

RecyclerView is shown as empty

My recyclerView is not showing anything. I looked through the other similar questions posted on the site, but I can't find anything that seems relevant. When I open the activity, I just see the bar on top with the app name and nothing else below it.
My goal is to get a list of items, where each item has a "delete" icon that can be clicked to delete it. For this purpose, I have a custom layout for the recyclerView item.
I made a simplified version of the code to try and isolate the problem. Here it is:
Activity:
public class CategoryManagerActivity extends AppCompatActivity {
private RecyclerView categoryRecyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_category_manager);
categoryRecyclerView = findViewById(R.id.category_edit_recycler);
ArrayList<String> categoryList = new ArrayList<>();
categoryList.add("CAT1");
categoryList.add("CAT2");
categoryList.add("CAT3");
CategoryEditRecyclerViewAdapter adapter = new CategoryEditRecyclerViewAdapter(categoryList);
categoryRecyclerView.setLayoutManager(new LinearLayoutManager(this));
categoryRecyclerView.setAdapter(adapter);
}
}
Adapter class:
public class CategoryEditRecyclerViewAdapter extends
RecyclerView.Adapter<CategoryEditRecyclerViewAdapter.CategoryEditViewHolder>{
private ArrayList<String> categories;
public CategoryEditRecyclerViewAdapter(ArrayList<String> items){
categories = items;
}
#NonNull
#Override
public CategoryEditViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
Context context = parent.getContext();
View view = LayoutInflater.from(context).inflate(R.layout.categories_edit_recycler_item,
parent, false);
return new CategoryEditRecyclerViewAdapter.CategoryEditViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull CategoryEditViewHolder holder, int position) {
final String category = categories.get(position);
holder.categoryName.setText(category);
holder.deleteButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
delete_category(category);
}
});
}
#Override
public int getItemCount() {
return categories.size();
}
private void delete_category(String category){
//I have code here to delete an item
}
public class CategoryEditViewHolder extends RecyclerView.ViewHolder{
TextView categoryName;
ImageView deleteButton;
public CategoryEditViewHolder(View itemView) {
super(itemView);
categoryName = itemView.findViewById(R.id.categoryEditText);
deleteButton = itemView.findViewById(R.id.deleteCategory);
}
}
}
recyclerView item layout:
(I used the #drawable/delete in other activities in the app, so I don't think it should be a problem)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

android:orientation="vertical">
<androidx.constraintlayout.widget.ConstraintLayout
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/categoryEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="24dp"
android:layout_marginTop="22dp"
android:layout_marginBottom="690dp"
android:text="TextView"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="1.0" />
<ImageView
android:id="#+id/deleteCategory"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginTop="22dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="679dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:srcCompat="#drawable/delete" />
</androidx.constraintlayout.widget.ConstraintLayout>
</LinearLayout>
Activity layout:
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />

try this for item layout

Modify your RecyclerView Item Layout s below.
<RelativeLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:id="#+id/categoryEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="24dp"
android:layout_marginTop="22dp"
android:text="TextView" />
<ImageView
android:id="#+id/deleteCategory"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_marginTop="22dp"
android:layout_marginEnd="16dp"
android:layout_alignParentEnd="true"
android:src="#drawable/ic_drawable_delete" />
</RelativeLayout>

Please modify your categories_edit_recycler_item Item Layouts below:
<?xml version="1.0" encoding="utf-8"?>

Main Fragment Overlaps with child fragment

I am trying to make a basic Countdown app.
Below is my main Activity
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/chronometer" />
</android.support.constraint.ConstraintLayout>
I have created two fragments
1)SetTimer.java\fragment_set_timer.xml With a EditText and Button
2)TimerButtons.java\fragment_timer_buttons.xml Three Buttons
SetTimer Activity is below
public class SetTimer extends Fragment{
View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view=inflater.inflate(R.layout.fragment_set_timer, container, false);
Button button=(Button)view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
FragmentManager fm=getFragmentManager();
FragmentTransaction ft =fm.beginTransaction();
Fragment fragment=new TimerButtons();
ft.replace(R.id.fragment,fragment);
ft.addToBackStack(null);
ft.commit();
}
});
return view;
}}
SetTimer xml is below
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

app:layout_constraintStart_toEndOf="#+id/editText2"
app:layout_constraintTop_toTopOf="parent"
/>
</android.support.constraint.ConstraintLayout>
</FrameLayout>
When i run the project and click on Set Button
this is what happens
and background frame is even Clickable
but shouldn't using .replace() destroy previous fragment
Why is it happening and how can i correct it?

SwipeToRefreshview swipe error

I have a swipe to refresh view and a listview within in the swipe to refresh view
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout

android:layout_marginBottom="0dp"
app:layout_constraintBottom_toBottomOf="parent">
</ListView>
</android.support.constraint.ConstraintLayout>
</android.support.v4.widget.SwipeRefreshLayout>
I can scroll down the list but when i want to go back up, the swipe to refresh kicks in and I got to be able to view the entire list, any recommendations ??
and this is the implementation for the listener
srl = (SwipeRefreshLayout) view.findViewById(R.id.refreshView);
srl.setOnRefreshListener(srfListener());
function for listener
protected SwipeRefreshLayout.OnRefreshListener srfListener() {
return new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
update();
}
};
}
and update function
#Override
protected void update() {
HomeActivity.getInstance().onResume();
srl.setRefreshing(false);
}

Use like this
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swipe_refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/ArrayList"
android:scrollbars="vertical"
android:paddingBottom="85dp"
android:clipToPadding="false"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.v4.widget.SwipeRefreshLayout>

<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/refreshView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ListView
android:id="#+id/ArrayList"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_marginTop="0dp"
app:layout_constraintTop_toTopOf="parent"
android:layout_marginRight="0dp"
app:layout_constraintRight_toRightOf="parent"
android:layout_marginLeft="0dp"
app:layout_constraintLeft_toLeftOf="parent"
android:layout_marginBottom="0dp"
app:layout_constraintBottom_toBottomOf="parent">
</ListView>
</android.support.v4.widget.SwipeRefreshLayout>
Swipe refresh view should only wrap around the listview/recyclerViews .....not around the parent view

Try this:
srl.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener()
{
#Override
public void onRefresh()
{
update();
}
});
instead of this:
protected SwipeRefreshLayout.OnRefreshListener srfListener() {
return new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
update();
}
};
}
Xml:
Take Linear layout instead of ConstraintLayout.

CardView doesn't work properly

I have a work with the RecyclerView, and I use the CardView as well.I have made all these standards procedures (created the ViewHolder, implemented necessary methods) but the problem is that CardView's corners aren't rounded.I get only rectangular corners of the CardView.
Here is the XML code of Adapter's "main layout":
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="250dp"
android:layout_margin="15dp"
card_view:cardElevation="10dp"
card_view:cardCornerRadius="30dp">
<RelativeLayout
android:layout_margin="20dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/adapterText"
android:text="#string/textCaption"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/adapterDate"
android:text="#string/date"
android:layout_marginTop="10dp"
android:layout_alignParentStart="true"
android:layout_alignParentLeft="true"
android:layout_below="#+id/adapterText"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
</android.support.v7.widget.CardView>
And another layout with RecyclerView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_margin="10dp"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/contactList"
android:scrollbars="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
And initialization of the RecyclerView:
#Override
public void onViewCreated(View root, Bundle savedInstanceState) {
if (root != null) {
RecyclerView mRecyclerContactList=(RecyclerView)(root.findViewById(R.id.contactList));
mContactAdapter=new ContactAdapter(getContext(),mContextualMultiMode,mContactList);
mRecyclerContactList.setAdapter(mContactAdapter);
RecyclerView.ItemAnimator animator=new DefaultItemAnimator();
mRecycle
rContactList.setItemAnimator(animator);
RecyclerView.ItemDecoration mVerticalDecoration=new DividerItemDecoration
(getContext(), LinearLayoutManager.VERTICAL);
mRecyclerContactList.addItemDecoration(mVerticalDecoration);
mRecyclerContactList.setLayoutManager(new LinearLayoutManager(getContext()));
}
}
Does anybody know how to solve this issue?

Cardview as root causes strange problems to me. Try to use Relativelayout as root.

Hi try using this code
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cardview="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="250dp"
android:baselineAligned="false"
android:elevation="6dp"
cardview:cardCornerRadius="6dp"
cardview:cardElevation="6dp"
cardview:cardPreventCornerOverlap="false"
cardview:cardUseCompatPadding="true"
cardview:contentPadding="0dp">
</android.support.v7.widget.CardView>

Use this code when you are using cardview
<android.support.v7.widget.CardView
android:id="#+id/cardview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:elevation="100dp"
card_view:cardBackgroundColor="#color/cardview_initial_background"
card_view:cardCornerRadius="8dp"
android:layout_marginLeft="#dimen/margin_large"
android:layout_marginRight="#dimen/margin_large"
