unable to fetch images in image slider in fragment

unable to fetch images in image slider in fragment - java

When I extend an Activity this works fine, but when extending ActivityFragment I get an error:
unable to resolve constructor
At this line: BaseViewPagerAdapter<String> adapter = new BaseViewPagerAdapter<String>(this). I'm just fetching the image from a URL and displaying it in an image slider. If anyone knows any links or tutorials feel free to suggest me. Thanks.

onClick event badly managed with three recyclerviews

I'm displaying three recyclerviews inside a fragment. I have recently changed my implementation so I can display some feature on a dropdown menu while long pressing on an item inside one of the three recyclerview.
Since then my app treats the click event on the two first recyclerview incorrectly (out of bound issue) and I know from debbuging that those click events are managed onely by the third adapter.
Here's my fragment code displaying the three recyclerviews:
public class ActivityFragment extends Fragment {
private int Index;
private ForecastRecyclerAdapter FirstView_Adapter;
private ForecastRecyclerAdapter SecondView_Adapter;
private ForecastRecyclerAdapter ThirdView_Adapter;
private CardView FirstCard, SecondCard, ThirdCard;
private LinearLayout SeparatorLayout1, SeparatorLayout2;
private ArrayList<MainViewArrayListRecycler> ListFirstView;
private ArrayList<MainViewArrayListRecycler> ListSecondView;
private ArrayList<MainViewArrayListRecycler> ListThirdView;
public static ActivityFragment newInstance(int Index) {
Bundle args = new Bundle();
ActivityFragment fragment = new ActivityFragment();
args.putInt(GETINDEX, Index);
fragment.setArguments(args);
return fragment;
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View mview = inflater.inflate(R.layout.fragment_mainactivity_forecast, container, false);
if (getArguments() != null) {
Index = getArguments().getInt(GETINDEX);
}
ViewModel viewModel = new ViewModelProvider(this).get(ViewModel.class);
viewModel.getInfo().observe(getViewLifecycleOwner(), Informations -> {
if (Informations != null) {
FillUpArray(Informations.get(Index));
}
});
FirstCard = mview.findViewById(R.id.FirstCard);
SecondCard = mview.findViewById(R.id.SecondCard);
ThirdCard = mview.findViewById(R.id.ThirdCard);
SeparatorLayout1 = mview.findViewById(R.id.SeparatorLayout1);

What can be the issue ?

get context after returning from adapter to fragment

I am using contextual action bar in my fragment("UnitsFragment.java") to delete and edit items of recyclerview. But when I come back from recyclerview adapter class("UnitsRv.java"). The context seems to be null. I tried returning context from adapter and it worked for function "prepareSelection". However for "onActionItemClicked" under ActionMode.callback, I need to get context so that I can use alertdialog for editing the items.
The "requireContext()" throws this error: Fragment UnitsFragment{e3a36c8 (b4957397-055a-4b1c-8af2-fee89a3e9b35)} not attached to a context.
Here are my codes.

This is my Adapter class.

v.setOnLongClickListener(this);
}
#Override
public void onClick(View view) {

}
}
#Override

return true;
}
}
#NonNull
#Override

View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.units_item, parent, false);
return new ViewHolder(itemView);
}
#Override
public void onBindViewHolder(#NonNull final ViewHolder holder, final int position) {
holder.unit_name.setText(munitsLists.get(position).getUnit_name());
if (UnitsFragment.isInActionMode){
if (UnitsFragment.selectionList.contains(munitsLists.get(position))){
holder.itemView.setBackgroundResource(R.color.colorSelected);
}
}
}
#Override
public int getItemCount() {
return munitsLists.size();
}
public static ArrayList<UnitsList> getDataSet() {
return munitsLists;
}
public void changeDataItem(int position, UnitsList unitsList) {
munitsLists.set(position, unitsList);
notifyDataSetChanged();
}
public void removeData(ArrayList<UnitsList> list) {
for (UnitsList unitsList : list) {
munitsLists.remove(unitsList);
}
notifyDataSetChanged();
}
}

First, you should not create instance of your UnitsFragment inside your adapter.
You can use EventBus to communicate between Activities, Fragments, Adapters, etc.
Or You can do your task using interface. like below.
Create an interface like this
public interface AdapterCallback {
void prepareSelection(Context context,int position);
}
In your UnitsFragment implement the above interface. like the following
public class UnitsFragment extends Fragment implements AdapterCallback{
// your other codes
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_units, container, false);
setHasOptionsMenu(true);
// .... your other codes
Log.d(TAG, "onCreateView: " + getContext());
// modify below line like this
mAdapter = new UnitsRv(mcontext, unitsLists, this); // here you have to pass an extra parameter that will implement your callback method from adapter.
recyclerView.setAdapter(mAdapter);
return rootView;
}
// ... you other codes
#Override
public void prepareSelection(Context context,int position) {
if(actionMode == null) {
isInActionMode = true;
for (String string : list) {
unitsLists.add(new UnitsList(string));
}
mAdapter = new UnitsRv(context, unitsLists,this); // add this as parameter.
Log.d(TAG, "prepareSelection: " + mAdapter);
Log.d(TAG, "prepareSelection1: " + dcontext);
mcontext = (Activity)context;
actionMode = mcontext.startActionMode(actionModeCallback);
mAdapter.notifyDataSetChanged();
if (!selectionList.contains(unitsLists.get(position))) {
selectionList.add(unitsLists.get(position));
}
updateViewCounter();
}
}
// other codes
}
Now, inside your Adapter you need to add an extra argument in constructor of UnitsRv and call your interface method from adapter ussing mAdapterCallback.
public class UnitsRv extends RecyclerView.Adapter<UnitsRv.ViewHolder> {
private static final String TAG = "UnitsRv";
private static ArrayList<UnitsList> munitsLists = new ArrayList<>();
UnitsFragment unitsFragment = new UnitsFragment(); // remove this line
private AdapterCallback mAdapterCallback; // add this line
Context mcontext;
public UnitsRv(Context context,ArrayList<UnitsList> unitsLists, AdapterCallback callback) {
mcontext = context;
munitsLists = unitsLists;
this.mAdapterCallback = callback; // add this line
}
class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
TextView unit_name;
public ViewHolder(View v) {
super(v);
unit_name = v.findViewById(R.id.unit_name);
v.setOnLongClickListener(this);
}
#Override
public void onClick(View view) {
if (UnitsFragment.isInActionMode){
mAdapterCallback.prepareSelection(mcontext,getAdapterPosition()); // modify this line
notifyItemChanged(getAdapterPosition());
}
}
#Override
public boolean onLongClick(View view) {
Log.d(TAG, "onLongClick: " + getAdapterPosition());
mAdapterCallback.prepareSelection(view.getContext(),getAdapterPosition()); // modify this line
return true;
}
}
// your other codes....
}

You should check for your fragment is attached or not with isAdded()
place if(!isAdded()) return in your onActionItemClicked. and replace requireContext() with getContext() because requireContext() always throws IllegalStateException if fragment is not attached.

override onAttach method to save context in your fragment.
#Override
public void onAttach(Context context) {
super.onAttach(context);
this.context= context;
}
Hope this helps.

How to display the Auto Scrolling RecyclerView position on TextView?

I am doing an app which auto-scrolls images, at the bottom of the screen there is a static layout, which I need to display the value of images that have already passed (i.e. position).
I get the correct value of images passed by implementing :
int position = holder.getAdapterPosition();
in the RecyclerViewListAdapter.java
now I need to display this value in the RecyclerViewListActivity.java
on a text view at the static layout beneath the Recycler view?
public class RecyclerViewListAdapter extends RecyclerView.Adapter {
Context context;
List<Data> dataList;
private SharedPreferences preferences;
public RecyclerViewListAdapter(Context context, List<Data> dataList) {
this.context = context;
this.dataList = dataList;

}
#Override
public void onBindViewHolder(final MyViewHolder holder, final int position) {
holder.mImage.setImageResource(dataList.get(position).getImage());
holder.mImage.setImageResource(dataList.get(position).getImage());
**int position = holder.getAdapterPosition();**
}
#Override
public int getItemCount() {
if (dataList == null || dataList.size() == 0)
return 0;
return dataList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder {

So, How can I show the position value on textView in a real-time, as position is a dynamic value, I expect the output on the textView to change as the images passed to the top.
Many Thanks in advance.

This how I solve my problem:
I save the position value in a power Preference(an easier version of shared Preferences)-many thanks to:
Ali Asadi(https://android.jlelse.eu/powerpreference-a-simple-approach-to-store-data-in-android-a2dad4ddc4ac)
I use a Thread that updates the textview every second-many thanks to:

Thanks for all.

OnClickListener in PagerAdapter

I have an Activity that uses a ViewPager, within this ViewPager is a TouchImageView (an ImageView that detects gestures and zooms/moves accordingly).
Now I want to change some things in the UI whenever the image is clicked, but because the TouchImageView is declared in the PagerAdapter I can't reach it and if I would setup something on the side of the PagerAdapter I couldn't reach the UI components I want to change (I would also like to use the same adapter somewhere else in my app when I got this working). I've tried setting up an onClickListener on the ViewPager itself, but that doesn't trigger. Now I really don't know what to do.
Here is the adapter:
public class FullScreenImageAdapter extends PagerAdapter {
private ArrayList<MediaFile> images;
public FullScreenImageAdapter( ArrayList<MediaFile> images) {
this.images = images;
}
#Override
public int getCount() {
return images.size();
}
#Override
public View instantiateItem(ViewGroup container, int position) {
TouchImageView img = new TouchImageView(container.getContext());
Bitmap bitmap = BitmapFactory.decodeFile(images.get(position).getPath());
img.setImageBitmap(bitmap);
container.addView(img, ViewPager.LayoutParams.MATCH_PARENT, ViewPager.LayoutParams.MATCH_PARENT);
return img;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
}
And here is the method that interacts with it (in the ProjectOverviewActivity class):
private void viewPicture(final int position) {
View decorView = getWindow().getDecorView();
statusBarVisibility = decorView.getSystemUiVisibility();
// Hide the status bar.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
} else {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
FullScreenImageAdapter imageAdapter = new FullScreenImageAdapter(mediaFiles);
final ViewPager viewPager = (ViewPager) findViewById(R.id.image_pager);
viewPager.setAdapter(imageAdapter);
viewPager.setCurrentItem(position);
View fancyBox = findViewById(R.id.fancyBox);
fancyBox.setVisibility(View.VISIBLE);
viewPager.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View btnClose = findViewById(R.id.fancyBoxBtnClose);
View btnPrev = findViewById(R.id.fancyBoxBtnPrev);
View btnNext = findViewById(R.id.fancyBoxBtnNext);
if (overlayButtonsVisible) {
btnClose.setVisibility(View.GONE);
btnPrev.setVisibility(View.GONE);
btnNext.setVisibility(View.GONE);
} else {
btnClose.setVisibility(View.VISIBLE);
if (viewPager.getCurrentItem() > 0) {
btnPrev.setVisibility(View.VISIBLE);
}
if (viewPager.getCurrentItem() < (mediaFiles.size() - 1)) {
btnNext.setVisibility(View.VISIBLE);
}
}
overlayButtonsVisible = !overlayButtonsVisible;
}
});
View fancyBoxBtnClose = findViewById(R.id.fancyBoxBtnClose);
final View fancyBoxBtnPrev = findViewById(R.id.fancyBoxBtnPrev);
final View fancyBoxBtnNext = findViewById(R.id.fancyBoxBtnNext);
fancyBoxBtnClose.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View decorView = getWindow().getDecorView();
// Show the status bar.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
decorView.setSystemUiVisibility(statusBarVisibility);
} else {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, statusBarVisibility);
}
findViewById(R.id.fancyBox).setVisibility(View.GONE);
setViewAndChildrenEnabled(findViewById(R.id.layoutProjectOverview), true);
overlayButtonsVisible = false;
}
});
fancyBoxBtnPrev.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewPager.setCurrentItem(viewPager.getCurrentItem() - 1);
if (viewPager.getCurrentItem() == 0) {
fancyBoxBtnPrev.setVisibility(View.GONE);
}
}
});
fancyBoxBtnNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewPager.setCurrentItem(viewPager.getCurrentItem() + 1);
if (viewPager.getCurrentItem() == (mediaFiles.size() - 1)) {
fancyBoxBtnNext.setVisibility(View.GONE);
}
}
});
}

You can try this
Update:
I think you should create your custom ViewPager with GestureDetector
Example:
public class ClickableViewPager extends ViewPager {
private OnItemClickListener mOnItemClickListener;
public ClickableViewPager(Context context) {
super(context);
setup();
}
public ClickableViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
setup();
}
private void setup() {
final GestureDetector tapGestureDetector = new GestureDetector(getContext(), new TapGestureListener());
setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
tapGestureDetector.onTouchEvent(event);
return false;
}
});
}
public void setOnItemClickListener(OnItemClickListener onItemClickListener) {
mOnItemClickListener = onItemClickListener;
}
public interface OnItemClickListener {
void onItemClick(int position);
}
private class TapGestureListener extends GestureDetector.SimpleOnGestureListener {
#Override
public boolean onSingleTapConfirmed(MotionEvent e) {
if(mOnItemClickListener != null) {
mOnItemClickListener.onItemClick(getCurrentItem());
}
return true;
}
}
}
and then in your activity
ClickableViewPager viewPager = (ClickableViewPager) findViewById(R.id.viewPager);
viewPager.setOnItemClickListener(new ClickableViewPager.OnItemClickListener() {
#Override
public void onItemClick(int position) {
// HADNLE YOUR CLICKS
}
});

please helpme...i'm a beginner :)

Create the adapter like so:
public class CustomAdapter extends RecyclerView.Adapter<Custom.ViewHolder> {
private List<SomeObject> mDataSet;
public OnItemClickListener mItemClickListener;
private Context mContext;
public CustomAdapter(Context context, List<SomeObject> myDataset, OnItemClickListener mItemClickListener) {
this.mDataSet = myDataset;
this.mItemClickListener = mItemClickListener;
this.mContext = context;
}
public void updateData(List<SomeObject> mDataSet) {
this.mDataSet = mDataSet;
notifyDataSetChanged();
}
public void removeItem(int position) {
mDataSet.remove(position);
notifyItemRemoved(position);
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
return new ViewHolder(v);
}
#Override
public void onBindViewHolder(final ViewHolder holder, int position) {
// - get element from your dataset at this position
// - replace the contents of the view with that element
final SomeObject obj = mDataSet.get(position);
holder.name.setText(obj.getName());
}
#Override
public int getItemCount() {
return mDataSet.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
TextView name;
public ViewHolder(View v) {
super(v);
name = (TextView) v.findViewById(R.id.naam);
v.setOnClickListener(this);
v.setOnLongClickListener(this);
}
#Override
public void onClick(View v) {
// If not long clicked, pass last variable as false.
mItemClickListener.onItemClick(v, getLayoutPosition(), false, mDataSet);
}
#Override
public boolean onLongClick(View v) {
// If long clicked, passed last variable as true.
mItemClickListener.onItemClick(v, getLayoutPosition(), true, mDataSet);
return true;
}
}
public interface OnItemClickListener {
void onItemClick(View view, int position, boolean isLongClick, List<SomeObject> mFilteredList);
}
}
And set the adapter like this:
mAdapter = new CustomAdapter(getActivity(), dataSet, new CustomAdapter.OnItemClickListener() {
#Override
public void onItemClick(View v, int position, boolean isLongClick, List<SomeObject> mDataSet) {
if (isLongClick) {
//Long click
SomeObject obj = mDataSet.get(position);
} else {
//Normal click
SomeObject obj = mDataSet.get(position);
}
}
});

Use interfaces to handle onClicks.
Put this in the adapter:
public interface OnItemClickListener {
void onClickItem(View view, int position);
}
public void SetOnItemClickListener(OnItemClickListener mItemClickListener) {
this.mItemClickListener = mItemClickListener;
}
and then in view holder do this:
public class PasalBabVH extends RecyclerView.ViewHolder {
public TextView p_TextView;
public TextView b_TextView;
public PasalBabVH(View itemView) {
super(itemView);
p_TextView = (TextView) itemView.findViewById(R.id.uud_pasal);
b_TextView = (TextView) itemView.findViewById(R.id.uud_bab);
p_TextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mItemClickListener != null) {
}
}
});
b_TextView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (mItemClickListener != null) {
}
}
});
}
public void bind(PasalBabModel mx) {
p_TextView.setText(mx.getpasalbab_p());
b_TextView.setText(mx.getpasalbab_b());
}
}
In fragment do this:
adapter.SetOnItemClickListener(new PasalBabAdapter.OnItemClickListener() {
#Override
public void onClickItem(View view, int position) {
}});
