1px artifact in middle of range selection

[npmrtsv]

When I'm using custom CellDecorator with DayViewAdapter, I have a strange artefact.

@quaddef without seeing your code, it's impossible to diagnose. either share your xml+DayViewAdapter+CellDecorator code, or try to repro in the sample app and comment here with a link to your fork

@edenman Ok, no problem, here is an example. https://github.com/quaddef/android-times-square-example

i have some problem to, when i set the divider color to 0 (i want no divider) in CalenderPickerView, this thing happen

Here is my code
Day view Adapter

public class MyDayViewAdapter implements DayViewAdapter {
    @Override
    public void makeCellView(CalendarCellView parent) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_custom_dayview,parent);
        TextView textView = (TextView)v.findViewById(R.id.my_day_textview);
        parent.setDayOfMonthTextView(textView);
    }

CellDecorator

public class MyDecorator implements CalendarCellDecorator {
    @Override
    public void decorate(Context context, CalendarCellView cellView, Date date) {
        ImageView image = (ImageView) cellView.getChildAt(0).findViewById(R.id.my_day_imageview);
        TextView textView = (TextView)cellView.getChildAt(0).findViewById(R.id.my_day_textview);
        textView.setTextColor(cellView.getContext().getColor(R.color.whiteText));
        if(!cellView.isEnabled()||!cellView.isSelectable()){
            textView.setTextColor(cellView.getContext().getColor(R.color.myInactive));
        }
        if(cellView.getRangeState().equals(RangeState.FIRST)){
            image.setImageResource(R.drawable.bg_firstrange_sample);
        }
        else if(cellView.isSelected()&&cellView.isToday()){
            image.setImageResource(R.drawable.bg_selected_sample);
        }
        else if(cellView.getRangeState().equals(RangeState.MIDDLE)){
            image.setImageResource(R.drawable.bg_midrange_sample);
        }
        else if(cellView.getRangeState().equals(RangeState.LAST)){
            image.setImageResource(R.drawable.bg_range_last);
        }
        else if(cellView.isToday()){
            image.setImageResource(R.drawable.bg_today_sample);
        }
        else if(cellView.isSelected()){
            image.setImageResource(R.drawable.bg_selected_sample);
        }
        else
            image.setImageResource(0);
    }
}

custom dayview xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@null">
    <ImageView
        android:id="@+id/my_day_imageview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@null"/>
    <TextView
        android:id="@+id/my_day_textview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        style="@style/CalendarCell.CalendarDate"
        android:layout_gravity="center"
        android:text=""/>
</FrameLayout>

Sorry for delayed response. I looked at this a bit on Friday but couldn't figure out why there's a 1px gap. I'll try to look again soon, but can't promise I'll get to it this week. Let me know if you figure it out.

@edenman Sometimes such artifacts happen using ViewPager with non-standard page width, for example 7% of the view's width.

Maybe there is another way to disable the divider except make it 0 in CalenderPickerView.class ?

I have this exact issue that I commented in #371

I have this exact issue #377

Same issue at our side #377

I was able to workaround this problem.

I checked the values for width at CalendarCellView and the generated TextView and found out, that they do not match always.

At my device (Samsung Galaxy S7) with a full width of 1080 the CalendarCellView got following width values (from left to right per row)
154,154,154,155,154,154,155 - thats fine to get the full 1080. But the TextView was always set to 154.

So I created my own DayViewTextView class inherited from TextView and just overrode the layout method in following way

override fun layout(l: Int, t: Int, r: Int, b: Int) {
        super.layout(l, t, (parent as CalendarCellView).width, b)
    }

After that I created my own DayViewAdapter and just adapted it from the default one but used DayViewTextView:

object dayViewAdapter : DayViewAdapter {
        override fun makeCellView(parent: CalendarCellView) {
            val textView = DatePickerTextView(ContextThemeWrapper(parent.context, com.squareup.timessquare.R.style.CalendarCell_CalendarDate))
            textView.isDuplicateParentStateEnabled = true
            parent.addView(textView)
            parent.setDayOfMonthTextView(textView)
        }
    }

and used it

calendarPickerView.setCustomDayView(dayViewAdapter)

This solved the problem with the small gap.
