Custom Adapter

[alaa7731]

again, thank you for your work so far.

I have a question regarding implementing Custom adapter, I assume that the Type of adapter can be anything, so in case i made the type as a custom model, which have icon and text, and need to implement the adapter to have icon and text, in the onSegmentBind how can I know if this is the selected or not?

is it even possible to implement it like that, below is my implementation for the custom ViewHolder

public class AppSegmentedViewHolder extends SegmentViewHolder<SegmentedTypeModel> {
    TextView tvTitle;
    ImageView ivIcon;

    public AppSegmentedViewHolder(@NonNull View sectionView) {
        super(sectionView);
        tvTitle = sectionView.findViewById(R.id.tvTitle);
        ivIcon = sectionView.findViewById(R.id.ivIcon);

    }

    @Override
    protected void onSegmentBind(SegmentedTypeModel segmentedTypeModel) {
        tvTitle.setText(segmentedTypeModel.getTitle());
        ivIcon.setImageResource(segmentedTypeModel.getIcon());
    }
}

Hi !!! try to override onSegmentSelected(boolean isSelected, boolean isReselected) method inside your AppSegmentedViewHolder.

Also take a look at this utility helper class, for background and radius handling

https://github.com/RobertApikyan/SegmentedControl/blob/master/segmentedcontrolmodule/src/main/java/segmented_control/widget/custom/android/com/segmentedcontrol/utils/Utils.java

As an example of implementation look at SegmentAdapterImpl.java and SegmentViewHolderImpl.java classes

great, will check it and give you the result after that

below are my SegmentViewHolder & SegmentAdapter

SegmentAdapter

public class AppSegmentedAdapter extends SegmentAdapter<SegmentedTypeModel, AppSegmentedViewHolder> {
    private Context context;

    public AppSegmentedAdapter(Context context) {
        this.context = context;
    }

    @NonNull
    @Override
    protected AppSegmentedViewHolder onCreateViewHolder(@NonNull LayoutInflater layoutInflater, ViewGroup viewGroup, int i) {
        return new AppSegmentedViewHolder(context, layoutInflater.inflate(R.layout.segmented_item, null));
    }
}

SegmentViewHolder

public class AppSegmentedViewHolder extends SegmentViewHolder<SegmentedTypeModel> {
    TextView tvTitle;
    ImageView ivIcon;
    Context context;

    public AppSegmentedViewHolder(Context context, @NonNull View sectionView) {
        super(sectionView);
        this.context = context;
        tvTitle = sectionView.findViewById(R.id.tvTitle);
        ivIcon = sectionView.findViewById(R.id.ivIcon);

    }

    @Override
    protected void onSegmentBind(SegmentedTypeModel segmentedTypeModel) {
        tvTitle.setText(segmentedTypeModel.getTitle());
        ivIcon.setImageResource(segmentedTypeModel.getUnselectedIcon());
    }

    @Override
    public void onSegmentSelected(boolean isSelected, boolean isReselected) {
        super.onSegmentSelected(isSelected, isReselected);

        if (isSelected) {
            tvTitle.setTextColor(ContextCompat.getColor(context,R.color.colorPrimaryDark));
            ivIcon.setColorFilter(ContextCompat.getColor(context,R.color.colorPrimaryDark));
        }else{
            tvTitle.setTextColor(ContextCompat.getColor(context,R.color.colorPrimary));
            ivIcon.setColorFilter(ContextCompat.getColor(context,R.color.white));
        }
    }
}

I have a class called SegmentedTypeModel which is my custom model , contains Text and Icon

[alaa7731]

and my implementation of setAdapter

segmentedTypesFilter.setAdapter(new AppSegmentedAdapter(MessageListActivity.this));

        ArrayList<SegmentedTypeModel> bottomFilter = new ArrayList<SegmentedTypeModel>();

        SegmentedTypeModel segmentedTypeModel = new SegmentedTypeModel();
        segmentedTypeModel.setTitle("1");
        segmentedTypeModel.setSelectedIcon(R.drawable.platinum_icon_act);
        segmentedTypeModel.setUnselectedIcon(R.drawable.platinum_icon);
        bottomFilter.add(segmentedTypeModel);

        segmentedTypeModel = new SegmentedTypeModel();
        segmentedTypeModel.setTitle("2");
        segmentedTypeModel.setSelectedIcon(R.drawable.elder_act);
        segmentedTypeModel.setUnselectedIcon(R.drawable.elder);
        bottomFilter.add(segmentedTypeModel);

        segmentedTypeModel = new SegmentedTypeModel();
        segmentedTypeModel.setTitle("3");
        segmentedTypeModel.setSelectedIcon(R.drawable.disabled_act);
        segmentedTypeModel.setUnselectedIcon(R.drawable.disabled);
        bottomFilter.add(segmentedTypeModel);

        segmentedTypesFilter.addSegments(bottomFilter);

My Bad, i found the problem, I was assigning an array in the XML, which cause the exception, when i removed it it works
