Question

我想制作一个标记信息窗口，它有3行，每条单行包含2种颜色。我在

的帮助下制作了3行

 class MyTask extends AsyncTask<Void,Void,String>
{
    EditText et1 = (EditText)findViewById(R.id.et1);

    public String doInBackground(Void... unused)
    {
        HttpURLConnection conn = null;
        try
        {
            URL url = new URL("http://www.free-map.org.uk/course/mad/ws/hits.php?artist=",et1);
            conn = (HttpURLConnection) url.openConnection();
            InputStream in = conn.getInputStream();
            if(conn.getResponseCode() == 200)
            {
                BufferedReader br = new BufferedReader(new InputStreamReader(in));
                String result = "", line;
                while((line = br.readLine()) !=null)
                    result += line;
                return result;
            }
            else
                return "HTTP ERROR: " + conn.getResponseCode();
        }
        catch(IOException e)
        {
            return e.toString();
        }
        finally
        {
            if(conn!=null)
                conn.disconnect();
        }
    }

但我对颜色很感兴趣。

请帮助：）

您可以使用 SpannableString 在TextView或其他启用文字的组件中的单个字符串句子中设置多种颜色

String strMessage="I am android developer";
Spannable spannable = new SpannableString(strMessage);

//"I am android" red colored
spannable.setSpan(getTextAppearanceSpan(ContextCompat.getColor(mContext, android.R.color.RED)), 0, 12, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        textView.setText(spannable);


//"developer" blue colored
spannable.setSpan(getTextAppearanceSpan(ContextCompat.getColor(mContext, android.R.color.BLUE)), 14, strMessage.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        textView.setText(spannable);

TextAppearanceSpan 方法，以自定义文字颜色

/*
 *get customized text with color, style
 */
private TextAppearanceSpan getTextAppearanceSpan(int color) {
    ColorStateList blueColor1 = new ColorStateList(new int[][]{new int[]{}}, new int[]{color});
    return new TextAppearanceSpan(null, Typeface.NORMAL, -1, blueColor1, null);
}
