But I don't know what should I do to change color of some words.

Please tell me what should I do?

Answer 1

How about using a WebView instead of a TextView, then you can just update the HTML. It is definitely uses more resources, but may do what you need.

Answer 2

Use Html.fromHtml to create a Spanned text and assign it to the TextView.

Answer 3

I thought that you want to provide About us/Help file inside your android application , then you can perform as the following:

1. Create a Help file in HTML
2. Put that HTML Help file inside the assets folder that you found inside your Android project structure
3. Now, you can load that HTML file inside the WebView using the below code:

webview.loadUrl("file:///android_asset/about_applicatio.html");

This way you can create a HTML file and thereby you can apply the color/javascript/bold/italic that you want inside the HTML file.
