Dynamic Components

This project contains a set of useful classes which can be used to hold various data sources regardless of their format.

DynamicText

Data class which can be used to combine String data with string resource identifiers. Can be used for regular strings or plurals.

Use the library adding implementation 'com.twocoders.dynamic:text:3.0.0' into your build.gradle file.

Usage

One of the usage cases this comes handy is when you want to conditionally set either String text or StringRes id to one TextView using data-binding.

Code in ViewModel:

val title = MutableLiveData<DynamicText>()

fun onDataLoaded(response: Response) {
    title.value = if (response.success) {
        DynamicText.from(response.data.title) //-> data.title is String
    } else {
        DynamicText.from(R.string.oh_no) //-> id of a string from resources is Int
    }
}

Code in layout file:

<TextView
    android:text="@{viewModel.title}" />

DynamicColor

Data class which can be used to hold ColorInt, ColorRes or AttrRes data.

Use the library adding implementation 'com.twocoders.dynamic:color:1.0.0' into your build.gradle file.

Usage

One of the usage cases this comes handy is when you want to conditionally set either ColorInt or ColorRes to one View using data-binding.

Code in ViewModel:

val backgroundColor = MutableLiveData<DynamicColor>()

fun onDataLoaded(response: Response) {
    backgroundColor.value = if (response.success) {
        DynamicColor.fromColorInt(response.data.backgroundColor) //-> data.backgroundColor is ColorInt
    } else {
        DynamicColor.fromColorRes(R.color.red) //-> R.color.red is ColorRes
    }
}

Code in layout file:

<View
    android:background="@{viewModel.backgroundColor}" />
