ImageGetter

Small simple library for downloading images in textView when applying text from html. Uses Picasso as dependency.

Turns this	Into this

To use in simple case of loading images into textView you can use two arguments constructor in which you pass your instance of Picasso and TextView into which pictures should be loaded.

val imageGetter = PicassoImageGetter(Picasso.get(), textView)
textView.text = HtmlCompat.fromHtml(simpleExampleText, HtmlCompat.FROM_HTML_MODE_LEGACY, imageGetter, null)

If needed you can specify UrlEditor if urls you get from html are not full, or need to be modified. Also you can specify placeholder resources for loading and error.

exampleTextView.run {
            val exampleGetter = PicassoImageGetter().apply {
                picasso = Picasso.get()
                textView = this@run
                placeHolderRes = R.drawable.ic_image_black
                errorDrawableRes = R.drawable.ic_error_black
                urlEditor = { source: String ->
                    when {
                        source.startsWith(":") -> "http$source"
                        source.startsWith("/") -> "http:$source"
                        else -> source
                    }
                }
            }
            text = HtmlCompat.fromHtml(exampleText, HtmlCompat.FROM_HTML_MODE_LEGACY, exampleGetter, null)
        }

See the example app for more detailes.

To use this library:

Step 1. Add it in your root build.gradle at the end of repositories:

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Step 2. Add the dependency

	dependencies {
	        implementation 'com.github.ruslansharipov:imagegetter:0.1.0'
	}

Based on this https://stackoverflow.com/a/36251602/10951565 If you don't want to use dependency you can just copy PicassoImageGetter.kt into your project This library is very welcome for contributions, especially for other popular image loading libraries like Glide and Malevich.
