I am trying to make a custom adapter for listview. I've used ArrayList for storing objects of 'CustomListDataModel' class. But when I set Image or textview resources in 'getView()' Such as
viewHolder.image_view.setImageResources(customListDataModelArrayList.get(pos).getImage_id());
showing that getImage_id() is 'cannot resolve'.
This is my problem. getImage_id() method that I set as a getter in 'CustomListDataModel' for specifying my problem clearly here is my code:
public class MainActivity extends AppCompatActivity {
ListView list_view;
CustomListAdapter customListAdapter;
ArrayList <CustomListDataModel> customListDataModelArrayList =new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PopulateData();
initView();
}
public void initView(){
list_view = (ListView) findViewById(R.id.list_view);
customListAdapter = new CustomListAdapter(MainActivity.this, customListDataModelArrayList);
list_view.setAdapter(customListAdapter);
}
public void PopulateData(){
for (int i=0;i<10;i++){
CustomListDataModel customListDataModel = new CustomListDataModel();
switch (i)
{
case 0:
customListDataModel.setImageName("Angry Bird Red");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is red in color");
break;
case 1:
customListDataModel.setImageName("Angry Bird Black");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is black in color");
break;
case 2:
customListDataModel.setImageName("Angry Bird Blue");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is blue in color");
break;
case 3:
customListDataModel.setImageName("Angry Bird Red");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is red in color");
break;
case 4:
customListDataModel.setImageName("Angry Bird Black");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is black in color");
break;
case 5:
customListDataModel.setImageName("Angry Bird Blue");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is blue in color");
break;
case 6:
customListDataModel.setImageName("Angry Bird Green");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is green in color");
break;
case 7:
customListDataModel.setImageName("Angry Bird Yellow");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is yellow in color");
break;
case 8:
customListDataModel.setImageName("Angry Bird White");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is white in color");
break;
case 9:
customListDataModel.setImageName("Angry Bird Red");
customListDataModel.setImage_id(R.drawable.angry_bird);
customListDataModel.setImageDiscription("Angry Bird is white in color");
break;
}
customListDataModelArrayList.add(customListDataModel);
}
}
}
public class CustomListDataModel {
private String ImageName="";

}
public void setImageDiscription(String imageDiscription) {
ImageDiscription = imageDiscription;
}
public int getImage_id() {
return Image_id;
}
public void setImage_id(int image_id) {
Image_id = image_id;
}
}
public class CustomListAdapter extends BaseAdapter{

public static class ViewHolder{

}
ViewHolder viewHolder = null;
// this method is called each time for arraylist data size.
@Override
public View getView(int position, View view, ViewGroup viewGroup) {
View vi=view;
final int pos = position;
if(vi == null){
// create viewholder object for list_rowcell View.
viewHolder = new ViewHolder();

}else {
