[英]Android rich text Mark Down
I'm looking for a library or optimized examples on using Mark Down to create Rich Text. 我正在寻找使用Mark Down创建Rich Text的库或优化示例。
For example, something to turn: 例如,要转向:
1 - *Bold* -> Bold 1 - * Bold * - > Bold
2 - _Italic_ -> Italic 2 - _Italic_ - > 斜体
Long example: 很长的例子:
3 - _Hello_ *World* -> Hello World 3 - _Hello_ *世界* - > Hello World
And so on. 等等。
I've seen many apps use it, like Discord, Whatsapp, Skype. 我见过许多应用程序使用它,如Discord,Whatsapp,Skype。
I've done something similar, but I know it's not optimized and can lead to runtime errors. 我做了类似的事情,但我知道它没有优化,可能导致运行时错误。
You don't need any extra library... 你不需要任何额外的库......
Just have a look into android.text.SpannableStringBuilder
... 看看android.text.SpannableStringBuilder
......
This will allow you to get text features like: 这将允许您获得如下文本功能:
Here you have an example on how to apply a Bold style on a word in a TextView : 这里有一个关于如何在TextView中对单词应用粗体样式的示例:
String text = "This is an example with a Bold word...";
// Initialize a new SpannableStringBuilder instance
SpannableStringBuilder strb = new SpannableStringBuilder(text);
// Initialize a new StyleSpan to display bold text
StyleSpan bSpan = new StyleSpan(Typeface.BOLD);
// The index where to start applying the Bold Span
int idx = text.indexOf("Bold");
strb.setSpan(
bSpan, // Span to add
idx, // Start of the span
idx + 4, // End of the span
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
);
// Display the spannable text to yourTextView
yourTextView.setText(ssBuilder);
I think you have to look for library that support mark down 我认为你必须寻找支持降价的图书馆
SpannableStringBuilder str = new SpannableStringBuilder("Your awesome text");
str.setSpan(new android.text.style.StyleSpan(android.graphics.Typeface.BOLD), start_int, end_int, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView tv=new TextView(context);
tv.setText(str);
