Combine use of OnClickListener and OnLong Click Listener

Actually I created a pdf viewer and i jus want to create a longclicklistener to open my new activity and as u can see here
Screenshot
And there is already a click listener assigned with this button and i also want to combine longclicklistener so when i long click that button then automatically launch my second activity
public void actionButtonClick(View view) {
if (pageCount == 0) {
Toast.makeText(getApplicationContext(), getString(R.string.no_selected_pdf), Toast.LENGTH_LONG).show();
return;
}
final BottomSheetDialog dialog = new BottomSheetDialog(MainActivity.this);
dialog.setContentView(R.layout.bottom_sheet);
dialog.setCanceledOnTouchOutside(true);
NumberPicker numberPicker = (NumberPicker) dialog.findViewById(R.id.number_picker);
if (numberPicker != null) {
numberPicker.setMaxValue(pageCount);
numberPicker.setValue(pdfView.getCurrentPage() + 1);
numberPicker.setOnValueChangedListener((picker, oldVal, newVal) -> {
pdfView.jumpTo(newVal - 1, true);
});
}
dialog.show();
}
public void openButtonClick(View view) {
launchPicker();
}
private void startAnimation(int state) {
actionLayout.animate()
.translationY(state == 0 ? actionLayout.getHeight() : 0)
.alpha(state == 0 ? 0 : 1.0f)
.setDuration(300).setListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
menu.findItem(R.id.hide_or_show_button).setChecked(state != 1);
super.onAnimationEnd(animation);
}
});
}
private void hideOrShowActionButton() {
if (actionLayout.getAlpha() == 1.0)
startAnimation(0);
else
startAnimation(1);
}
private void showSnackBar(#NonNull String msg, boolean isError) {
Snackbar snackbar = Snackbar
.make(findViewById(R.id.main_layout), msg, Snackbar.LENGTH_SHORT);
snackbar.setBackgroundTint(ContextCompat
.getColor(Objects.requireNonNull(getApplicationContext()),
isError ? R.color.err_color : R.color.main_color));
snackbar.setTextColor(ContextCompat
.getColor(Objects.requireNonNull(getApplicationContext()), R.color.white));
snackbar.show();
}
#Override
public void loadComplete(int nbPages) {
pageCount = nbPages;
warningLayout.setVisibility(View.GONE);
PdfDocument.Meta meta = pdfView.getDocumentMeta();
detailsMap.clear();
detailsMap.add(meta.getTitle());

String date = data.substring(2);
String y = date.substring(0, 4);
String m = date.substring(4, 6);
String d = date.substring(6, 8);
return y + "/" + m + "/" + d;
} else {
return data;
}
}
#Override

How can I show image in Recyclerview - Recyclerview image display error

Firstly sorry if my english explanation is bad. My issue is, I am trying to make weather app and I want to show 5 day forecast.I keep the data in arraylist that I pull in api and send to my adapter class. As you know weahter icons are expressed as string in weather api. such as "010d" is sunny something like that.I am going to show recyclerview that I wrote 5 day forecast. Everything is working but icons doesn't show. I am sharing codes that I did.

i am using other layout elements and recyclerview in a layout and inflating cardview layout in oncreateViewHolder (custom adapter). Methods are only called when i just user recyclerview in a layout not with other layout elements.

you replace this
static class BidsAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> implements
RecyclerView.OnItemTouchListener {
instead
static class BidsAdapter extends RecyclerView.Adapter<BidsAdapter.BidView> implements
RecyclerView.OnItemTouchListener {

android - MapFragment inside ScrollView inside Fragment

My goal is to let MapFragment handle touch event instead of ScrollView.
MapFragment is being added programmatically inside of ScrollView which is inside of Fragment.

mapFragment = new FragmentMap();
getChildFragmentManager().beginTransaction().add(R.id.fragment_map, mapFragment, TAG).commit();
getChildFragmentManager().executePendingTransactions();
FragmentMap looks like this:
public class FragmentMap extends SupportMapFragment {
private OnTouchListener mListener;
private boolean mTouchListener = false;
#Override
public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstance) {
View layout = super.onCreateView(layoutInflater, viewGroup, savedInstance);
TouchableWrapper frameLayout = new TouchableWrapper(getActivity());
frameLayout.setBackgroundColor(getResources().getColor(android.R.color.transparent));
frameLayout.addView(layout);
setListener(new OnTouchListener() {
#Override
public void onTouch() {
//Prevents NullPointerException
}
});
return frameLayout;
}
public void setListener(OnTouchListener listener) {
mListener = listener;
}
public interface OnTouchListener {
public abstract void onTouch();
}
public boolean getTouch() {
return mTouchListener;
}
public class TouchableWrapper extends FrameLayout {
public TouchableWrapper(Context context) {
super(context);
}
#Override
public boolean dispatchTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mTouchListener = true;
break;
case MotionEvent.ACTION_UP:
mTouchListener = false;
break;
}
mListener.onTouch();
return super.dispatchTouchEvent(event);
}
}
}
I set listener on a map:
mapFragment.setListener(new FragmentMap.OnTouchListener() {
#Override
public void onTouch() {
scrollView.requestDisallowInterceptTouchEvent(true);
}
});
This is supposed to work when map fragment is declared in the XML layout but when I am adding it programmatically, it doesn't.

To enable or disable intercepting event in a parent view, you have Android's onInterceptTouchEvent(MotionEvent ev) method. But it is propagated from the top-down (i.e. the parent view returns true if it consumed the event, false otherwise) . So create a class extending the ScrollView, and override that method:
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if(checkCoordinateCross(ev, YOUR_TARGET_VIEW_ID)) {
return false;
}
return true;
}
private boolean checkCoordinateCross(MotionEvent ev, int resId) {
View target = findViewById(resId);
if(target == null) {
return false;
}
if(ev.getX() > target.getX() && ev.getX() < target.getX() + target.getWidth() && ev.getY() > target.getY() && ev.getY() < target.getY() + target.getHeight()) {
return true;
}
return false;
}
Note that YOUR_TARGET_VIEW_ID has to be the child of the ScrollView or findViewById(...) will return null.
