Step 1: Format the Java String as html
String formattedMessage = document.replaceAll("(\\r|\\n)", "<br/>");
formattedMessage = formattedMessage.replaceAll("\\s", " ");
Step 2: Display the text in a pre tags
StringBuilder sb = new StringBuilder();
sb.append("<html><body><pre>");
sb.append(formattedMessage);
sb.append("</pre></body></html>");
return sb.toString();
Step 3: Display in an AlertDialog using a WebView
public void showHtml(String html) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.dialog_information);
WebView webView = new WebView(this);
webView.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
webView.loadData(html, "text/html", "utf-8");
builder.setView(webView);
builder.show();
}
