Android 进度对话框消息中的两种颜色文本

Question

我有一个进度对话框，我想显示如下文本消息

1. 下载
2. 解压

我可以将“1. 正在下载”显示为绿色，将“2. 解压缩”显示为红色。我的代码在哪里

mProgressDialog.setMessage("1. Downloading \n 2. Decompressing");

Answer 1

看看这段代码。

final SpannableStringBuilder sb = new SpannableStringBuilder("your text here");
   final ForegroundColorSpan fcs = new ForegroundColorSpan(Color.rgb(158, 158, 158)); 

   // Span to set text color to some RGB value
   final StyleSpan bss = new StyleSpan(android.graphics.Typeface.BOLD); 

   // Span to make text bold
   sb.setSpan(fcs, 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE); 

   // Set the text color for first 4 characters
   sb.setSpan(bss, 0, 4, Spannable.SPAN_INCLUSIVE_INCLUSIVE); 

   // make them also bold
   yourTextView.setText(sb);
