Usage

1. Add the library as a dependency

1.1 in Project level build.gradle add those repositories

   maven { url  'https://dl.bintray.com/sysdata/maven' }
   maven { url 'http://repo.pageturner-reader.org' }
   mavenCentral()

1.2 in your App level build.gradle add this dependecy

    implementation 'it.sysdata.mobile:htmlspanner:1.0.0'
    implementation 'net.sourceforge.htmlcleaner:htmlcleaner:2.16'

1.3 Use HtmlSpanner in your TextView :

In the xml layout file define a simple TextView then in the Activity do

        String html=loadStringFromAssetFile(this,"example.html");
        TextView tv = (TextView) findViewById(R.id.text);
        int col=tv.getSolidColor();
        HtmlSpanner htmlSpanner=new HtmlSpanner(tv.getCurrentTextColor(), tv.getTextSize());
        htmlSpanner.setBackgroundColor(col);
        tv.setText(htmlSpanner.fromHtml(html));

If you want to handle href you need to add

        tv.setMovementMethod(LinkMovementMethod.getInstance());

You can also use an SDHtmlTextView instead of text view :

1. Add the library as a dependency

1.1 in Project level build.gradle add those repositories

   maven { url  'https://dl.bintray.com/sysdata/maven' }
   maven { url 'http://repo.pageturner-reader.org' }
   mavenCentral()

1.2 in your App level build.gradle add this dependecy

    implementation 'it.sysdata.mobile:htmltextview:1.0.0'
    implementation 'net.sourceforge.htmlcleaner:htmlcleaner:2.16'

1.3 add the SDHtmlTextView via xml and then in your code set the html

kotlin:

        String html=loadStringFromAssetFile(this,"example.html")
        htmlTextView.htmlText = html

java:

        String html=loadStringFromAssetFile(this,"example.html");
        SDHtmlTextView htmlTextView = (SDHtmlTextView) findViewById(R.id.text);
        htmlTextView.setHtmlText(html);
