How to remove paddings from both sides? Or just put the element starting from the beginning, insterad of mid.

There's any way to remove the padding from the left to the element starts from the beginning of the layout?

Support multi line text

Hi thanks for the awesome library. I just had a small requirement where I needed to have a single textView but in 2 lines. For eg:
17/8 18/8
45 23

Something like the above. But at the moment, I don't think the library supports this feature. Can you please let me know how to enable this?

java.lang.RuntimeException

In case of low memory there is a RuntimeException because of the incomplete parcelable SavedState

exception java.lang.RuntimeException
message Parcel android.os.Parcel@42c741b0: Unmarshalling unknown type code 3014765 at offset 240

the solution is to simply add these lines to the SavedState Class

public static class SavedState extends BaseSavedState {

        .....

        @SuppressWarnings("hiding")
        public static final Parcelable.Creator<SavedState> CREATOR

Errore java.lang.NullPointerException: Attempt to read from null array & Rendering Problems

Hi, i have this problem with your library

first problem with layout :

Missing styles. Is the correct theme chosen for this layout? Use the Theme combo box above the layout to choose a different layout, or fix the theme style references. Failed to find style 'horizontalPickerStyle' in current theme (2 similar errors not shown) onLayout error java.lang.NullPointerException   at com.wefika.horizontalpicker.HorizontalPicker.startMarqueeIfNeeded(HorizontalPicker.java:886)   at com.wefika.horizontalpicker.HorizontalPicker.calculateItemSize(HorizontalPicker.java:859)   at com.wefika.horizontalpicker.HorizontalPicker.onSizeChanged(HorizontalPicker.java:442)

and next problem

     java.lang.NullPointerException: Attempt to read from null array

but in my activity

    HorizontalPicker test = (HorizontalPicker) findViewById(R.id.testPicker);

    List<String> listItems = new ArrayList<String>();

    listItems.add("Item1");
    listItems.add("Item2");
    listItems.add("Item3");

    final CharSequence[] charSequenceItems = listItems.toArray(new CharSequence[listItems.size()]);

    test.setSideItems(charSequenceItems.length);
    test.setValues(charSequenceItems);

in the logcat :: Caused by: java.lang.NullPointerException: Attempt to read from null array

thanks

NullPointerException when "Over Scroll Never" Used

Setting "Over Scroll Never" means that mLeftEdgeEffect and mRightEdgeEffect are null.

In this condition, if you touch the scroller, you encounter a NPE at line 482/487. Just needs a null check added.

Add padding between items

There should be option to set padding between individual items.

No divider shows up

No matter what values I put for picker:dividerSize or android:divder, no divider shows up. Is there something else I need to do?

Fading edges when using marquee

Add support for fading edges when using ellipsize="marquee"

Swipe directly leads on next or previous item

It'll be nice to have a mode for the HorizontalPicker where if the velocity of the swipe is huge, you don't scroll over 3,4,X items before stopping on an item far away but you only go to the next or the previous (swipe from left to right) item.

No resource identifier found for attribute 'dividerSize' in package 'com.wefika.horizontalpicker'

While running the application with the HorizontalPicker I am getting this error "Error:(33) No resource identifier found for attribute 'dividerSize' in package 'com.wefika.horizontalpicker'"

Change item background color depending on position

I have a picker with numbers, I need to segment the background in different colors depending on its value, for example: 1-5 red, 6-10 orange, 10-15 yellow.
How can I achieve this?

Thanks in advance

Conflicts with scrollview

Hi, First off, I love this library, and it works really fantastic.
One thing I seem to notice is that it conflicts with androids scrollview.
The slider would not show up if it is wrapped inside a scrollview.
Is there a possible work around for this?

Thank you

get values from HorizontalPicker

as the title says, how to get value from HorizontalPicker?

How reduce the space between items ?

How can we reduce the space between items ?

Error:(167) Attribute "values" has already been defined

The library has a conflict with MultiStateToggleButton library and most probably any library which contains attribute with the name values

Error:(167) Attribute "values" has already been defined

<declare-styleable name="MultiStateToggleButton">
<attr format="reference" name="values"/>
</declare-styleable>

This can be easily solved by adding a library prefix (hp_) for all the attributes that might cause such issues.

ArrayIndexOutOfBoundsException when setting sideItem

Hello,

I have some issues with the picker. My app is crashing everytime I set the side item and when I start to scroll or if the array has only one element. It's happening only in my phone, that's quite weird.
Furthermore, is it possible to change the text color of the middle item and not for all the elements?

Thanks!

Ellipsize marquee does not work

When ellipsize property is set to marquee text is drawn outside of its bounds instead of animating.

No resource identifier found for attribute

Hi blazsolar,
I have a problem to use your nice library. I really need it.
I'm using android studio 1.3.
After import your library through gradle, I added your example code at xml.
When build my project, that error occurs.

Error:(43) No resource identifier found for attribute 'values' in package 'com.wefika.horizontalpicker'
Error:(43) No resource identifier found for attribute 'dividerSize' in package 'com.wefika.horizontalpicker'
Error:(43) No resource identifier found for attribute 'sideItems' in package 'com.wefika.horizontalpicker'

Is it still working xmlns:picker="http://schemas.android.com/apk/res/com.wefika.horizontalpicker"?
Please let me know how to solve this problem.

Thank you!

Not working if put up in a Scroll View.

I am making a form where Horizontal Picker will be basic form of input. There are multiple entries in the form and therefore I need to put them in a ScrollView. But as soon I put it in ScrollView, none of the element show up. I tried doing nestedScrolling enabled, but no luck. Please help urgently.

Crashes on overscroll

My app is crashing when scrolling to the limits (end or to the start). Version 1.1.1.

Logcat is showing this Exception:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.EdgeEffect.onAbsorb(int)' on a null object reference
                                                                                at com.wefika.horizontalpicker.HorizontalPicker.computeScrollX(HorizontalPicker.java:806)

This is how I put HorizontalPicker in the layout:

<com.wefika.horizontalpicker.HorizontalPicker
                android:id="@+id/picker"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="center_vertical"
                android:marqueeRepeatLimit="-1"
                android:overScrollMode="never"
                android:ellipsize="marquee"
                android:layout_marginLeft="1dp"
                android:layout_marginRight="1dp"
                android:textColor="@android:color/black"
                android:textSize="18dp"
                />

And this is how I initialize it in my Activity:

String[] values = new String[160+1];
        for (int i = 0; i <= 160; i++) {
            values[i] = String.valueOf(i);
        }

        picker = (HorizontalPicker) findViewById(R.id.picker);
        picker.setOnItemClickedListener(this);
        picker.setOnItemSelectedListener(this);
        picker.setValues(values);
        picker.setSideItems(3);

What am I doing wrong?
Thanks in advance

Callbacks must add text or a content description in populateNodeForVirtualViewId()

Hi, may I know is this project no longer maintained?
Currently I found that it crashes in lots of Android 7.0/ 7.1.1 and some of Android 6.0 / 5.0 devices.
This may be a core library bugs in Android system which you have used.

The crash message is hard to read and untraceable.
Callbacks must add text or a content description in populateNodeForVirtualViewId()

I have googled, datePicker is a known bug in ALL Samsung Android 5.0 devices, but now it happens in Android 7.0 or above.

Selected item text color

Howdy! Is it possible to change the selected item text color?

Null pointer on mTextColor

When I try to open an activity that has the HorizontalPicker included I get the following error:

java.lang.NullPointerException: Attempt to invoke virtual method 'int android.content.res.ColorStateList.getDefaultColor()' on a null object reference
            at com.wefika.horizontalpicker.HorizontalPicker.getTextColor(HorizontalPicker.java:424)
            at com.wefika.horizontalpicker.HorizontalPicker.onDraw(HorizontalPicker.java:262)

I think it has something to do with using a custom style, but I don't know why exactly. It seems mTextColor is never set.

Null Pointer Exception

I've got one picker on the activity that when selected, populates another picker with values that depend on the selected item from the first picker.

second picker is defined as follows:

<com.wefika.horizontalpicker.HorizontalPicker
    xmlns:picker="http://schemas.android.com/apk/res/com.wefika.horizontalpicker"
    android:id="@+id/prod_category_picker"
    android:textColor="@color/light_gray"
    android:layout_below="@+id/prod_type_picker"
    android:layout_height="40dp"
    android:layout_width="match_parent"
    android:background="@color/slider_background"
    android:textSize="14sp"
    android:ellipsize="none"
    android:marqueeRepeatLimit="-1"
    android:visibility="gone"
    />

When I select an item in the first picker, intermittantly, I get this:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.graphics.RectF.set(android.graphics.RectF)' on a null object reference
        at com.wefika.horizontalpicker.HorizontalPicker.onDraw(HorizontalPicker.java:293)

I have not been able to figure out what sequence of events triggers this crash. Any thoughts?

Dynamically sized elements.

Is there a way to have the picker dynamically size the view that each option is in, instead of needing the ellipse?

Yeah, I know this would be an enhancement... thoughts?

Continue scroll/slide even with finger exits view bounds

This is something similar to how a browser's bottom / up scroll works while using a mouse. Hovering over the actual scrollbar to slide up & down is not required. The scroll bar can be caught and dragged up & down even with the mouse diagonally. The control stays with the mouse until the button is released. Similarly, while the MotionEvent.ACTION_MOVE event is fired, & the user leaves the bounds of the view, the view should keep scrolling until MotionEvent.ACTION_UP is registered.

I hope I was clear enough in the explanation. I'll post a small GIF if you want me to elucidate further.

Rendering Problems Missing styles. Is the correct theme chosen for this layout?

Failed to find style 'horizontalPickerStyle' in current theme (2 similar errors not shown) Couldn't resolve resource @dimen/textSize (2 similar errors not shown) java.lang.NumberFormatException: Color value '@color/textColor' must start with #   at com.android.layoutlib.bridge.impl.ResourceHelper.getColor(ResourceHelper.java:79)   at android.content.res.BridgeTypedArray.getColorStateList(BridgeTypedArray.java:372)   at com.wefika.horizontalpicker.HorizontalPicker.(HorizontalPicker.java:162)   at com.wefika.horizontalpicker.HorizontalPicker.(HorizontalPicker.java:140)

I traced the problem on textColor = a.getColorStateList(R.styleable.HorizontalPicker_android_textColor);

It says here that R.styleable was already removed: http://stackoverflow.com/questions/1717489/android-hello-gallery-tutorial-r-styleable-cannot-be-resolved

Boring Layouts do not show up when placed inside a ScrollView

The BoringLayout does not show up when the HorizontalPicker view is placed inside a ScrollView. It works flawlessly when the same is implemented elsewhere though. There's no exception thrown, and there are no call backs triggered when items are selected.

Null pointer exception when parent view became visible

My app has a RelativeLayout as a parent of HorizontalPicker. It has INVIZIBLE or GONE visibility value at application startup.
When I make RelativeLayout visible in my application, app crashes with Null Pointer exception .
Is it a bug or I am doing something wrong?

BTW, I am adding values programmatically by setValues() method.

Change color of selected item

I don't know where to look since there is not much documentation, but how do I change the color of the item that is selected (or change the color of hte unset items)

Right now every item is the same color and the end user might not now which item is selected

Maybe make it easier to style selected item (i.e. color and size)

it'd be cool to have methods to set the color and size of the selected item

Is it possible to set values of images in horizontal picker?

Text Typeface

Nice library!

Any way to change the typeface of the picker?

Thanks.

Null Pointer Exception

When trying to implement this, it throws the following null pointer during run time (omitting everything not within this package):
"java.lang.NullPointerException
at com.wefika.horizontalpicker.HorizontalPicker.startMarqueeIfNeeded(HorizontalPicker.java:876)
at com.wefika.horizontalpicker.HorizontalPicker.calculateItemSize(HorizontalPicker.java:853)
at com.wefika.horizontalpicker.HorizontalPicker.onSizeChanged(HorizontalPicker.java:441)"

My code is as follows:

where "WheelNums" is:

Also, I'm using version 1.0.1

I'm not sure if this is my fault or not, but feel free to correct me if it is!

PS - I believe your front page should read "xmlns:picker="http://schemas.android.com/apk/lib/com.wefika.horizontalpicker" " rather than "xmlns:picker="http://schemas.android.com/apk/res/com.wefika.horizontalpicker" " (lib vs res).

Thanks!
