使用Thread.currentThread().stackTrace获取调用者信息
本质是打印代码逻辑堆栈的方式，也是为了通过加日志定位一些调用关系的方法
val stack = Thread.currentThread().stackTrace
for (info in stack) {
Log.d("stackTrace_debug", info.toString())
}
一个例子
示例代码
获取指定堆栈的行数
2021-11-27 14:06:55.523 12533-12533/com.fadi.demo:ui D/UiModuleController: scan: called from: 4, caller: (MainActivity.java:201)<--(Instrumentation.java:1486), state: 0
完整如下
@AnyThread
fun scan(from: Int, callback: Callback? = null) {
Log.d(TAG, "scan: called from: $from, caller: ${LogUtils.getCaller()}, state: $state")
}
@JvmStatic
fun getCaller(): String {
val stack = Thread.currentThread().stackTrace
for (info in stack) {
Log.d("stackTrace_debug", info.toString())
}
return stack[4].simpleString() + "<--" + stack[5].simpleString()
}
打印结果
