android 正则表达式截取字符串问题

[weixin_36528687]

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.activity_main );
        textView = findViewById( R.id.textview );
        editText = findViewById( R.id.edittext );
        
        button1 = findViewById( R.id.button );
        button1.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String str = textView.getText().toString();
                String regEx = "--sector:\\s*?(\\d+),\\s*block:\\s*\\d+,\\s*key\\s*type:[A-Z],\\s*key\\s*count:\\s*\\d+\\s*Found";
                Pattern pattern = Pattern.compile( regEx );
                Matcher matcher = pattern.matcher( str );
                boolean s = matcher.matches();
                int i = (s==true?1:0);
                //System.out.print( s );

                String str2 = textView.getText().toString();
                String regEx2 = "type:([AB]),\\\\s*key\\\\s*count:\\\\s*\\\\d+\\\\s*Found";
                Pattern pattern2 = Pattern.compile( regEx2 );
                Matcher matcher2 = pattern2.matcher( str2 );
                boolean b = matcher2.matches();
                int o = (b==true?1:0);

     

                textView.setText("No key specified, trying default keys          \n" +
                        "--sector:13, block: 55, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "--sector:14, block: 59, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "--sector:15, block: 63, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "Found keys have been transferred to the emulator memory          \n");

                if(-1!= (textView.getText().toString().indexOf("Found keys have been transferred to the emulator memory")))
                {
                    ((SectorandKey) getApplication()).setI(textView.getText().toString());
                    ((SectorandKey) getApplication()).setO(textView.getText().toString());

                    editText.setText("hf mf nested 1 ".toCharArray(),i,o);
                }
            }


        } );

        }
    }

我是这样写的 为什么正则表达式没有截取到值呢 求大神解答一下 感谢啦

断点调试查看一下某个变量的值看看哦

"No key specified, trying default keys          \n" +
                        "--sector:13, block: 55, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "--sector:14, block: 59, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "--sector:15, block: 63, key type:B, key count:13           \n" +
                        "Found valid key:[ffffffffffff]          \n" +
                        "Found keys have been transferred to the emulator memory          \n"

请问就是这些数据，想要截取Found valid key:[ffffffffffff]上面出现的--sector后面的值，就比如说现在的数据，想要得到13，有什么办法吗

String result = "No key specified, trying default keys \n" +
"--sector:13, block: 55, key type:B, key count:13 \n" +
"Found valid key:[ffffffffffff] \n" +
"--sector:14, block: 59, key type:B, key count:13 \n" +
"Found valid key:[ffffffffffff] \n" +
"--sector:15, block: 63, key type:B, key count:13 \n" +
"Found valid key:[ffffffffffff] \n" +
"Found keys have been transferred to the emulator memory \n";
Pattern pattern = Pattern.compile("--sector:(.*)block");
Matcher m = pattern.matcher(result);
List<String> list= new ArrayList<>();
while (m.find()) {
list.add(m.group(1));
}
LogUtil.e(list);

Log输出 [13, , 14, , 15, ] 然后去掉每个item的都好就是了 //("--sector:(.*),block"); 这样截取的话输出是[]，不知道为什么

逗号和block之间空格了一个字符
