How to get size of a particular variable from Model class in Android?
2
I have a model class:
public class Home_Model_ViewPager {
public String buttonLink;
public String tipsDescription;
public String tipsButton;
public Context context;
public Home_Model_ViewPager( Context context, String tipsDescription, String tipsButton, String buttonLink) {
this.context = context;
this.tipsDescription = tipsDescription;
this.tipsButton = tipsButton;
this.buttonLink = buttonLink;
}
public String getButtonLink() {
return buttonLink;
}
public void setButtonLink(String buttonLink) {
this.buttonLink = buttonLink;
}
public String getTipsDescription() {
return tipsDescription;
}
public void setTipsDescription(String tipsDescription) {
this.tipsDescription = tipsDescription;
}
public String getTipsButton() {
return tipsButton;
}
public void setTipsButton(String tipsButton) {
this.tipsButton = tipsButton;
}
}
I have used this model class to use it in viewpager adapter.
So, I am using a recyclerview and setting data to it. Now I have a problem that I have a viewpager in recycleritem. I want to return the size of viewpager adapter of any element in Home_Model_ViewPager as each element has diff size.
This is what I tried in ViewPagerAdapter:
public class ViewPagerAdapter extends PagerAdapter {
// Declare Variables
Context context;
LayoutInflater inflater;
List<Home_Model_ViewPager> totalList;
public ViewPagerAdapter(Context context, List<Home_Model_ViewPager> totalList) {
this.context = context;
this.totalList = totalList;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return totalList.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, final int position) {
// Declare Variables
TextView tricksDescription;
Button tricksButton;
View itemView = inflater.inflate(R.layout.viewpager_item, container,
false);
tricksDescription = itemView.findViewById(R.id.xtv_tricks_description);
tricksButton = itemView.findViewById(R.id.tricks_button);
tricksDescription.setText(Html.fromHtml(totalList.get(position).getTipsDescription()));
tricksButton.setText(Html.fromHtml(totalList.get(position).getTipsButton()));
tricksButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
String url = totalList.get(position).getButtonLink();
intent.setData(Uri.parse(url));
startActivity(intent);
}
catch (Exception e) {
e.printStackTrace();
}
}
});
container.addView(itemView);
return itemView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
View view = (View) object;
container.removeView(view);
}
}
I am using volley to get the values as JSON..
private void Home() {
try {
if (getActivity()!=null)
Commonfunctions.LoadPreferences(getActivity());
System.out.println("Authtoken:" + Commonfunctions.Token_key);
appservice.View_All_Events(Commonfunctions.Token_key, String.valueOf(pagenumber), new Server_Callback() {

which size you want ?
– Rujul Gandhi
Nov 22 '18 at 7:04
the size/length oftipsin model class..
– sanjeev
Nov 22 '18 at 8:15
So in your case every object has only one tips Right ? or it can be more than 1 ?
– Rujul Gandhi
Nov 22 '18 at 8:52
@RujulGandhi the size of tips varies as the value of tips is received through API.

I have a model class:
public class Home_Model_ViewPager {
public String buttonLink;
public String tipsDescription;
public String tipsButton;
public Context context;
public Home_Model_ViewPager( Context context, String tipsDescription, String tipsButton, String buttonLink) {
this.context = context;
this.tipsDescription = tipsDescription;
this.tipsButton = tipsButton;
this.buttonLink = buttonLink;
}
public String getButtonLink() {
return buttonLink;
}
public void setButtonLink(String buttonLink) {
this.buttonLink = buttonLink;
}
public String getTipsDescription() {
return tipsDescription;
}
public void setTipsDescription(String tipsDescription) {
this.tipsDescription = tipsDescription;
}
public String getTipsButton() {
return tipsButton;
}
public void setTipsButton(String tipsButton) {
this.tipsButton = tipsButton;
}
}
I have used this model class to use it in viewpager adapter.
So, I am using a recyclerview and setting data to it. Now I have a problem that I have a viewpager in recycleritem. I want to return the size of viewpager adapter of any element in Home_Model_ViewPager as each element has diff size.
This is what I tried in ViewPagerAdapter:
public class ViewPagerAdapter extends PagerAdapter {
// Declare Variables
Context context;
LayoutInflater inflater;
List<Home_Model_ViewPager> totalList;
public ViewPagerAdapter(Context context, List<Home_Model_ViewPager> totalList) {
this.context = context;
this.totalList = totalList;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return totalList.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, final int position) {
// Declare Variables
TextView tricksDescription;
Button tricksButton;
View itemView = inflater.inflate(R.layout.viewpager_item, container,
false);
tricksDescription = itemView.findViewById(R.id.xtv_tricks_description);
tricksButton = itemView.findViewById(R.id.tricks_button);
tricksDescription.setText(Html.fromHtml(totalList.get(position).getTipsDescription()));
tricksButton.setText(Html.fromHtml(totalList.get(position).getTipsButton()));
tricksButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
String url = totalList.get(position).getButtonLink();
intent.setData(Uri.parse(url));
startActivity(intent);
}
catch (Exception e) {
e.printStackTrace();
}
}
});
container.addView(itemView);
return itemView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
View view = (View) object;
container.removeView(view);
}
}
I am using volley to get the values as JSON..
private void Home() {
try {
if (getActivity()!=null)
Commonfunctions.LoadPreferences(getActivity());
System.out.println("Authtoken:" + Commonfunctions.Token_key);
appservice.View_All_Events(Commonfunctions.Token_key, String.valueOf(pagenumber), new Server_Callback() {

So in your case every object has only one tips Right ? or it can be more than 1 ?

Please try to make one different array list for your viewpager's adapter:
ArrayList<Home_Model_ViewPager> tempList = new ArrayList<>();
for(int k=0;k<viewpagerData.size();k++){
Home_Model_ViewPager object = viewPagerData.get(k);
if(object.getTripDesc()!=null && object.getTripDesc().length() >0){
tempList.add(object);
}
}
ViewPagerAdapter pagerAdapter = new ViewPagerAdapter(getActivity(), tempList);
home_recycler.setAdapter(adapter);
adapter.notifyDataSetChanged();
