本文介绍了应用logcat的过滤器编程的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我需要过滤倾倒logcat的编程。我申请亚行logcat -s变量名，但应用程序只是挂。有一个类似的线程，但有没有办法解决：Read过滤日志猫（编程）？

  {尝试
            工艺过程=调用Runtime.getRuntime（）EXEC（logcat的-s XXX）。
            的BufferedReader的BufferedReader =新的BufferedReader（
                    新的InputStreamReader（process.getInputStream（）））;            StringBuilder的日志=新的StringBuilder（）;
            串线;
            而（（行= bufferedReader.readLine（））！= NULL）{
                log.append（线）;
                log.append（FragmentLog.LINE_SEPARATOR）;
            }            （（的TextView）TV）.setText（log.toString（））;        }赶上（IOException异常五）{
            （（的TextView）TV）.setText（R.string.default_blank）;
        }

解决方案

我是用另一种方式来获得我的应用程序的工作。这里是code，如果有人想知道，。

  {尝试
        工艺过程=调用Runtime.getRuntime（）EXEC（logcat的-d）;
        的BufferedReader的BufferedReader =新的BufferedReader（新的InputStreamReader（process.getInputStream（）））;        串线;        模式模式= Pattern.compile（XXX，0）;        而（（行= bufferedReader.readLine（））！= NULL）{
            如果（patternu！= NULL
                    ＆功放;＆安培; ！pattern.matcher（线）.find（））{
                继续;
            }
            log.append（线）;
            log.append（'\\ n'）;
        }    }赶上（IOException异常五）{    }

I need to dump logcat with filter programmatically. I applied adb logcat -s "TAGNAME" but the app just "hung". there is a similar thread but there is no solution: Read filtered log cat(Programmatically)?

        try {
            Process process = Runtime.getRuntime().exec("logcat -s XXX");
            BufferedReader bufferedReader = new BufferedReader(
                    new InputStreamReader(process.getInputStream()));

            StringBuilder log = new StringBuilder();
            String line;
            while ((line = bufferedReader.readLine()) != null) {
                log.append(line);
                log.append(FragmentLog.LINE_SEPARATOR);
            }

            ((TextView) tv).setText(log.toString());

        } catch (IOException e) {
            ((TextView) tv).setText(R.string.default_blank);
        }

解决方案

I am using another way to get my app work. Here is the code, in case anyone wants to know,.

    try {
        Process process = Runtime.getRuntime().exec("logcat -d");
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

        String line;

        Pattern pattern = Pattern.compile("XXX", 0);

        while ((line = bufferedReader.readLine()) != null) {
            if (patternu != null
                    && !pattern.matcher(line).find()) {
                continue;
            }
            log.append(line);
            log.append('\n');
        }

    } catch (IOException e) {

    }
