I have a ViewPager set up with my app and am trying to also set two floating action buttons, a left one and a right one, to do the same thing as the ViewPager, so that the user has a choice in terms of navigation. I'm trying to have it set so that the left button is invisible on the first page, and the right button is invisible on the last page, but the appearances of the buttons seem to be sporadic. I've tried debugging the app, and upon testing each situation, the appropriate code is executed, so I can't understand why this behavior is happening. Any help would be appreciated.

I'm using TabLayout and ViewPager in MainActivity and I want to open a specific website in a fragment(BrowserFragment) that contains a webview by clicking a button in another fragment(FragmentHome). In HomeFragment I've 2 buttons, goToFacebook which lead to Facebook and goToAmazon which lead to Amazon.

Hey guys I have a recyclerview adapter that populates list of some data on a cardview. I created a three dot menu towards the lower right bottom of the card layout which would actually delete the card row from the recyclerview and also make delete of the item from the sqlite database that stores rows data. The issue is I couldn't figure out how to integrate the method that would implement the delete into the recyclerview ViewHolder. Here is the source code
public class BeneficiaryRecyclerAdapter extends RecyclerView.Adapter<BeneficiaryRecyclerAdapter.BeneficiaryViewHolder> {
private List<Beneficiary> listBeneficiary;
public ImageView overflow;
private Context mContext;
public BeneficiaryRecyclerAdapter(){
}
public BeneficiaryRecyclerAdapter(List<Beneficiary> listBeneficiary, Context mContext) {
this.listBeneficiary = listBeneficiary;
this.mContext = mContext;
}
#Override
public BeneficiaryViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
// inflating recycler item view
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_beneficiary_recycler, parent, false);
return new BeneficiaryViewHolder(itemView);
}
#Override
public void onBindViewHolder(final BeneficiaryViewHolder holder, int position) {
holder.textViewName.setText(listBeneficiary.get(position).getName());
holder.textViewEmail.setText(listBeneficiary.get(position).getEmail());
holder.textViewAddress.setText(listBeneficiary.get(position).getAddress());
holder.textViewCountry.setText(listBeneficiary.get(position).getAddress());
holder.overflow.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showPopupMenu(holder.overflow);
}
});
}
/**
* Showing popup menu when tapping on 3 dots
*/
private void showPopupMenu(View view) {
// inflate menu
PopupMenu popup = new PopupMenu(this.mContext, view);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.beneficiary_m, popup.getMenu());
popup.setOnMenuItemClickListener(new MyMenuItemClickListener());
popup.show();
}
//NOTE: The method that would delete the item from the database and recyclerview but i need this method to be called from the onMenuItemClick of the case with id of case R.id.action_delete_beneficiary
public void deleteItem(final BeneficiaryViewHolder holder, int position) {
final DatabaseHelper2 db = new DatabaseHelper2(mContext);
db.open();
db.deleteContact(position);
db.close();
listBeneficiary.remove(position);
notifyItemRemoved(position);
notifyItemRangeChanged(position, listBeneficiary.size());
holder.itemView.setVisibility(View.GONE);
}
/**
* Click listener for popup menu items
*/
class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener {
public MyMenuItemClickListener() {
}
#Override
public boolean onMenuItemClick(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.action_delete_beneficiary:
Toast.makeText(mContext, "deleting beneficiary", Toast.LENGTH_SHORT).show();
return true;
case R.id.action_edit_beneficiary:
Toast.makeText(mContext, "editing beneficiary", Toast.LENGTH_SHORT).show();
return true;
default:
}
return false;
}
}
#Override
public int getItemCount() {
Log.v(BeneficiaryRecyclerAdapter.class.getSimpleName(),""+listBeneficiary.size());
return listBeneficiary.size();
}
/**
* ViewHolder class
*/
public class BeneficiaryViewHolder extends RecyclerView.ViewHolder {
public AppCompatTextView textViewName;
public AppCompatTextView textViewEmail;
public AppCompatTextView textViewAddress;
public AppCompatTextView textViewCountry;
public ImageView overflow;
public BeneficiaryViewHolder(View view) {
super(view);
textViewName = (AppCompatTextView) view.findViewById(R.id.textViewName);
textViewEmail = (AppCompatTextView) view.findViewById(R.id.textViewEmail);
textViewAddress = (AppCompatTextView) view.findViewById(R.id.textViewAddress);
textViewCountry = (AppCompatTextView) view.findViewById(R.id.textViewCountry);
overflow = (ImageView) view.findViewById(R.id.overflow);
}
}
}
I would be glad if anybody can help me with this.
Use this code to delete recyclerview items on same row click button.
holder.deleteImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(list.size()!=0){
list.remove(position);
notifyItemRemoved(position);
notifyItemRangeChanged(position,list.size());
}
}
});
I am trying to make an app that which is like a place picker, meaning you write down a product like pizza or burger, and u get all the places around you that have pizza or burger.
now I'm using RecyclerView in my fragment and i also have Map fragment

is this line come in 112 in your class file, it's seems like, you have not defined view id or view in XML, please check line number 112 in PlacesAdapter.class
Problem 1: Setting onclick listener twice. In onbindviewholder you have put holder.itemView.setOnclicklistener and then again in static class viewholder, you have put itemview.setOnclickListener. When you assign setOnclicklistener inside the static viewholder class, it means it will behave in a particular way uninfluenced by values present in any other views (like textview, imageview) or any such factors which depend on some 'value' property of the views. For most purposes you should have setOnClicklistener onto the itemview/textview/etc inside the static viewholder class which in your case is called placeholder.
Problem 2: Here is the reason why I believe you are getting NullPointerException. onbindviewholder has access to only the views declared in static viewholder class. If you want itemview to be accessible to onbindviewholder then make the following changes:
public static class PlaceHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
PlacesFragmantListener listener;
View iv;
public PlaceHolder(View itemView, PlacesFragmantListener placesFragmantListener) {
super(itemView);
iv = (View)itemView;
//then rest of the code
Now in your onbindviewholder write the following instead of holder.itemview.setonclicklistener
holder.iv.setonclicklistener...
Problem 3: in your static viewholder, you have put:
imgplace.setOnClickListener(this);
itemView.setOnClickListener(this);
itemview is the layout in which imgplace exists. And you have setonclicklistener on both of them. This is like putting a button on a button. It makes no sense. I think this will lead you into lot of mess. For some reason you want both to perform the same function on being clicked (you have put 'this' inside setOnClickListener). This is completely illogical. So set the clicklistener to either imgplace or itemview but not both
viewPager4 Fragment Activities
If I click on the Texts that play short sounds, one after another then after sometimes the mediaplayer hangs and doesn't play any sound. But if I'm able to destroy activity and recreate the same activity with refresh button in Action Bar, I'd be able to click sounds again.
So what to write in the code for R.id.item2?
Or there is any other way that continuous clicking on short sounds by these texts is possible without any hang kind of problem?
Following is the reference code:
public class module1 extends FragmentActivity {
static Context con;
static int length = 0;
ViewPager mViewPager;
SectionsPagerAdapter mSectionsPagerAdapter;
static MediaPlayer mediaplayer, mediaplayert, m;
#Override

con = this;
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
}

}

//what should i write here? to destroy and recreate the same fragment activity again.
//Problem: After clicking fast on one after another text links, mediaplayert hangs and doesnt play
//Solution: exit app destroy and reopen, then mediaplayer works fine...
