"bitcoin:address?label=mylabel&amount=12" 

然后返回比特币地址，金额，标签的值。

Answer 1

String bitcoinUrl = "bitcoin:address?label=mylabel&amount=12"; 
String address = bitcoinUrl.replaceAll("bitcoin:(.*)\\?.*", "$1"); 
String label = bitcoinUrl.replaceAll(".*label=(.*)&.*", "$1"); 
String amount = bitcoinUrl.replaceAll(".*amount=(.*)(&.*)?", "$1"); 

Log.d("bitcoin", address); 
Log.d("bitcoin", label); 
Log.d("bitcoin", amount); 

结果

D/bitcoin﹕ address 
D/bitcoin﹕ mylabel 
D/bitcoin﹕ 12
