add below library in your build.gradle file

compile 'org.jsoup:jsoup:1.8.3'

and

TextView txt_htmltext;
Button btn;


txt_htmltext = (TextView) findViewById(R.id.txt_htmltext);
btn = (Button) findViewById(R.id.btn);

txt_htmltext.setText(R.string.temp_html_text);

btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        txt_htmltext.setText(html2text(txt_htmltext.getText().toString()));
    }

});

public String html2text(String html) {
    try {
        return Jsoup.parse(html).text();
    } catch (Exception ignored) {
