Multi audio picker customization

The multi audio picker customization modifier

You'd be calling a picker using

    //multi picker as simple as
    MultiVideoPicker.showPicker(context = this){ doSomethingWithTheImageList(it) }

Where the pickerModifier = {} is a lambda that builds MultiAudioPickerModifier that inherits all of the arguments from BaseMultiPickerModifier except it has an additional viewHolderTitleTextModifier

The BaseMultiPickerModifier has

    doneButtonModifier: DoneButtonModifier
    titleTextModifier: TitleTextModifier
    selectIconModifier: SelectIconModifier
    unSelectedIconModifier: SelectIconModifier
    indicatorsGravity: Gravity
    viewHolderPlaceholderModifier: ImageModifier
    noContentTextModifier: TitleTextModifier
    loadingIndicatorTint: Int?
    viewHolderTitleTextModifier: TitleTextModifier 

So you have two options on how to customize the picker, it is really user preference, whether you choose to do one approach or the other it's up to you, do note that if you're using

   titleTextModifier.apply {

   }

Use a lambda function

   setupBaseMultiPicker(
                    tintForLoadingProgressBar = ContextCompat.getColor(this@MainActivity, R.color.colorPrimaryDark),
                    gravityForSelectAndUnSelectIndicators = BaseMultiPickerModifier.Gravity.TOP_RIGHT,
                    titleModifications = {
                        textAlignment = TextView.TEXT_ALIGNMENT_CENTER
                        textStyle = TitleTextModifier.TextStyle.ITALIC
                        textColor = Color.BLACK
                        marginBottom = 30 // use dp or sp this is only for demonstration purposes
                        textPadding = 5 // use dp or sp this is only for demonstration purposes
                        textSize = 30f  // use sp this is only for demonstration purposes
                        textString = "Pick multiple audios"
                    },
                    selectIconModifications = {
                        resID = R.drawable.ic_checked
                        tint = Color.BLACK
                    },
                    unSelectIconModifications = {
                        resID = R.drawable.ic_unchecked
                        tint = Color.BLACK
                    },
                    viewHolderPlaceholderModifications = {
                        resID = R.drawable.ic_close
                    }
            )

      setupViewHolderTitleText {
                
            }

Option 1

     MultiAudioPicker.showPicker(this, {

            viewHolderTitleTextModifier.apply {

            }
            loadingIndicatorTint = Color.RED // or use ContextCompat.getColor
            titleTextModifier.apply {

            }
            noContentTextModifier.apply {

            }

        },::doSomethingWithAudioList)

Option 2

MultiAudioPicker.showPicker(this, {
            setupViewHolderTitleText {
                textColor = ContextCompat.getColor(this@MainActivity, R.color.colorPrimaryDark)
                textStyle = TitleTextModifier.TextStyle.BOLD
                textPadding = 10 // use dp or sp this is only for demonstration purposes
            }
            setupBaseMultiPicker(
                    tintForLoadingProgressBar = ContextCompat.getColor(this@MainActivity, R.color.colorPrimaryDark),
                    gravityForSelectAndUnSelectIndicators = BaseMultiPickerModifier.Gravity.BOTTOM_LEFT,
                    titleModifications = {
                        textAlignment = TextView.TEXT_ALIGNMENT_VIEW_START
                        textStyle = TitleTextModifier.TextStyle.ITALIC
                        textColor = Color.BLACK
                        marginBottom = 30 // use dp or sp this is only for demonstration purposes
                        textPadding = 5 // use dp or sp this is only for demonstration purposes
                        textSize = 30f  // use sp this is only for demonstration purposes
                        textString = "Pick multiple songs"
                    },
                    selectIconModifications = {
                        resID = R.drawable.ic_checked
                        tint = Color.BLACK
                    },
                    unSelectIconModifications = {
                        resID = R.drawable.ic_unchecked
                        tint = Color.BLACK
                    },
                    viewHolderPlaceholderModifications = {
                        resID = R.drawable.ic_album_second
                    }
            )
        }, ::doSomethingWithAudioList)

It's really important to restore the listeners state, so in your onRestoreInstanceState, you need to call restore listener

 override fun onRestoreInstanceState(savedInstanceState: Bundle) {
        super.onRestoreInstanceState(savedInstanceState)
        //audios
        MultiAudioPicker.restoreListener(this, ::loadAudios)
    }
