android log util中的行号

Question

有没有办法用android Log打印文件行号？

Answer 1

获取行号`

public static int getLineNumber() {
    return Thread.currentThread().getStackTrace()[2].getLineNumber();
}
or 
Thread.currentThread().getStackTrace()[2].getLineNumber()
 in Log()

` 尝试它会帮助你....

Answer 2

为了实现这一点，这就是我所做的（％L输出行号）：

## log4j.properties
log4j.rootLogger=DEBUG, CA

log4j.appender.CA=org.apache.log4j.ConsoleAppender

log4j.appender.CA.layout=org.apache.log4j.PatternLayout
log4j.appender.CA.layout.ConversionPattern=%-4r [%t] %-5p %c %x (%F:%L) - %m%n

Answer 3

使用带有日志行号的木材更好地登录Android

在 /app/build.gradle 文件中

implementation 'com.jakewharton.timber:timber:4.7.1'

在“应用程序”类中

Timber.plant(new Timber.DebugTree() {
                @Override
                protected @Nullable String createStackElementTag(@NotNull StackTraceElement element) {
                    return super.createStackElementTag(element) + ":"+element.getLineNumber();
                }
            });

Answer 4

object Logg {
  private fun tag(): String? {
    return Thread.currentThread().stackTrace[4].let {
      "App# ${it.className.substringAfterLast(".")}.${it.methodName}(${it.fileName}:${it.lineNumber})"
    }
  }

  fun v(msg: String?) {
    Log.v(tag(), "" + msg)
  }

  fun d(msg: String?) {
    Log.d(tag(), "" + msg)
  }

  fun i(msg: String?) {
    Log.i(tag(), "" + msg)
  }

  fun w(msg: String?) {
    Log.w(tag(), "" + msg)
  }

  fun w(e: Throwable?) {
    Log.w(tag(), "" + e?.localizedMessage)
  }

  fun w(e: Exception?) {
    Log.w(tag(), "" + e?.localizedMessage)
  }

  fun e(msg: String?) {
    Log.e(tag(), "" + msg)
  }
}

使用方法：

Logg.e("====== log here ==========")

结果：
