Usage

XML

            android:id="@+id/snoo_body_view"
            android:padding="16dp"

See example

Java

Basic usage

SnooView snooView = (SnooView) findViewById(R.id.snoo_body_view);
SnooParser parser = new SnooParser();

String exampleHtml = getCommentHtml();
List<RedditBlock> blocks = parser.getBlocks(exampleHtml);

snooView.setBlocks(blocks);

Handling link clicks — Defaults to open in browser, but you can add your own listener

snooView.setOnUrlClickListener(new SnooView.OnUrlClickListener() {
    @Override
    public void onClick(String url) {
        Log.d(TAG, "Url clicked: " + url);
    }
});

Custom tag handling — <pre>, <hr/>, and <table> tags will not be affected

SnooParser parser = new SnooParser();

// Override how the <strong> tag is handled
// All bold text with the strong tag will be displayed as blue colored text
parser.replaceHandler("strong", new ExampleStrongHandler());

public class ExampleStrongHandler extends TagNodeHandler {
    @Override
    public void handleTagNode(TagNode node, SpannableStringBuilder builder, int start, int end) {
        builder.setSpan(new ForegroundColorSpan(Color.BLUE), start, end,
                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    }
}
