First and Last Position Need to add Long indicator with values

Hello

First and Last Position of Ruler need long indicator height with below text values.
for example if the min value is 10 and the maximum value is 30 then the ruler should start from 10 with long indicator and end with long indicator with value of 30. please help me to modify the library in that way.

Thank you,

Infinite value for the max_value

I want to scroll the item without any max_value number. then how can I set these?
I need to scroll the layout endless without any end point, and If there should be end point then last number of the Integer like Integer.MAX_VALUE.

Can anyone help on this?

New Idea

Please help me change modify some existing method to show text for diff time slots.

Thanks master

How to make vertical ruler picker?

Hi,
Is there is a way to make this ruler view vertical?

How to disable scrolling the ruler

Hi, is there a way to disable scrolling of the rule picker?

selectValue method isn't safe

so i've discovered that selectValue method isn't safe. If you call it multiple times in a row it will do some asynchroniuos way of setting value for each all which will eventually mess up the visible value (even if you're setting up the same value all the time).

Case of usage:

1. onCreateView you setlectValue and rotate the screen.
2. your onCreateView selectValue gets called and default selectValue from restoring state gets called
3. in result if you wanted to set value 1 in range [0, 10] your final value will be 2, if it was 2 then final value will be 4

set value

how to set the value for the ruler form the edit text.
I had already set selected value on initialize.
I am having edit text to enter the value on focus changed the value for the ruler is not set instead it is adding the value to the old value.

Importing ruler fails with Unable to merge dex exception

trying to use the ruler, but getting build errors. I've added this line to gradle:
implementation 'com.kevalpatel2106:ruler-picker:1.0'

synct and tried to build, got the error:
Error:java.lang.RuntimeException: java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
Error:java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

Error:com.android.dex.DexException: Multiple dex files define Landroid/support/design/widget/CoordinatorLayout$ViewElevationComparator;

Then i tried to enable multidexing, syncing and rebuilding again. I've set in gradle:
multiDexEnabled true

And got the following error while trying to rebuild:
Error:java.lang.RuntimeException: java.io.IOException: Can't write [../app/build/intermediates/multi-dex/debug/componentClasses.jar] (Can't read [../app/build/intermediates/transforms/desugar/debug/35.jar(;;;;;;* .class)] (Duplicate zip entry [35.jar:android/support/design/widget/CoordinatorLayout$Behavior.class]))

So some kind of dublicate zip entry... Removing implementation 'com.kevalpatel2106:ruler-picker:1.0' project compiles well... gonna try to investigate more...

Full error:

Would be usefull to be able to label each step, not only every 5 steps

It would be nice to be flexible on "what to label" and "how often to label".
I've given untested pull request of the fix which allows to customise the interval for long indicator.
Customising it will allow not only to place every "X" a long interval, but will place a label as well.

Usefull when you have a small ruler and want to have every value shown. So you could chose X = 1 and have all values labeled :).

Looking towards your test / merge aproval and next release. Cheers!

Custom interval support [QUESTION/FEATURE]

** Custom interval for each hop**

Really cool lib, did I miss something but is there a way to define custom intervals between each point.

Seems to me like current hop is 1. What if I want it to be 5, 10 , 100, making the scroll much more manageable ? Or do you already have that in? and I missed it?

onIntermediateValueChange gets called few times with same value

I've updated picker to 1.1 and i noticed that onIntermediateValueChange might be called a bit too often although it's value remains the same. Is it a desired functionality?

You can recreate this by having picker and two buttons: one to lower the value of the picker, another to rise it by 1. Picker limits are [1; 7]. Also we can notice a bit different behaviour while up / down are being pressed.

+extra: would be usefull to be able to label each step, not only every 5 steps =). Or every X steps.

        int counter = 3
         picker.selectValue(3);

        picker.setValuePickerListener(new RulerValuePickerListener() {
            @Override
            public void onValueChange(int x) {
                 counter = x;
                 displayNumber.setText(x);
            }

            @Override
            public void onIntermediateValueChange(int selectedValue) {
                displayNumber.setText(selectedValue );//get's a few calls with selectedValue being the same although we rise / lower by 1 
            }
        });

        down.setOnClickListener(v -> {
displayNumber.setText(counter - 1);
counter.selectValue(counter - 1); 
});
        up.setOnClickListener(v -> {
displayNumber.setText(counter +1);
counter.selectValue(counter + 1); 
});
