Android 自定义View 实现图文混排

对自定义标签 TagHandler处理

public class MTagHandler implements Html.TagHandler {
    private int mListItemCount = 0;
    private Vector<String> mListParents = new Vector<String>();
    private Vector<Integer> mListCounter = new Vector<Integer>();


    @Override
    public void handleTag(final boolean opening, final String tag, Editable output, final XMLReader xmlReader) {

        if (tag.equals("ul") || tag.equals("ol")) {
            if (opening) {
                mListParents.add(mListParents.size(), tag);
                mListCounter.add(mListCounter.size(), 0);

            } else {
                Log.d("Bohhh", " tolgo " + mListParents.get(mListParents.size() - 1));
                mListParents.removeElementAt(mListParents.size() - 1);
                Log.d("Bohhh", "lunghezza " + mListParents.size());
                mListCounter.removeElementAt(mListCounter.size() - 1);

            }

        } else if (tag.equals("li") && opening) {
            handleListTag(output);
        }


    }


    private void handleListTag(Editable output) {

        if (mListParents.lastElement().equals("ul")) {
            if (output.length() != 0)
                output.append("\n");
            for (int i = 1; i < mListCounter.size(); i++)
                output.append("\t");
            output.append("• ");
        } else if (mListParents.lastElement().equals("ol")) {
            mListItemCount = mListCounter.lastElement() + 1;
            if (output.length() != 0)
                output.append("\n");
            for (int i = 1; i < mListCounter.size(); i++)
                output.append("\t");
            output.append(mListItemCount + ". ");
            mListCounter.removeElementAt(mListCounter.size() - 1);
            mListCounter.add(mListCounter.size(), mListItemCount);
        }
    }
}
